The ever-increasing threat of coronavirus, but the global heating threat is even worse

Climate change is the greatest threat, The Canberra Times, 18 Jul 20    While the world was preoccupied with an ever increasing number of coronavirus cases this week, a hugely significant scientific report was allowed to pass under-reported and unremarked.

This was the study of the 2020 Siberian heatwave by World Weather Attribution, a group of scientists who have been monitoring extreme weather events for years.

The heatwave had contributed to raising the world’s average temperature to the second highest on record for the period from January to May this year.

WWA said Siberia had experienced “unusually high temperatures”, including a record-breaking 38 degrees celsius in the town of Verkhoyansk on June 20, causing wide-scale impacts including “wildfires, loss of permafrost, and invasion of pests”.

The Russian government was forced to declare a state of emergency in response to these disasters.   It is believed that at least 56 Megatons of carbon dioxide was released into the atmosphere in June alone. There has also been an explosion in the population of Siberian silk moths with massive swarms causing further damage to forests, making them even more prone to fire.

While all of this, and reports food supplies are being affected with fish swimming deeper in search of cooler water, is alarming, the real cause for concern is the finding the prolonged heatwave had been made “600 times more likely as a result of human-induced climate change”……….

while it is a given that the climate deniers will dismiss the report as “bunkum” and “fake news”, those who actually know what they are talking about have no such doubts.

Michael Wehner, a senior scientist at Lawrence Berkeley National Laboratory – who was not involved in the study – said the methodology was “state of the art” and that the findings were, if anything, “conservative”.

If, as many believe, temperatures in Arctic and Antarctic regions are “canaries in the coal mine”, this latest report is a warning that should not be ignored. Given it comes on top of linkages between Australia’s spring and summer bushfires and man-made global heating, it is yet another argument for this country to do much more to reduce to carbon dioxide emissions as a matter of urgency.

And let’s not forget, if 2019 was anything to go by, our next bushfire season is just around the corner.

While the federal government has done a commendable job in seeking the best possible expert advice on the coronavirus and then following it, it has yet to do the same with climate and energy policy. That has to change. Coronavirus is a crisis, climate change is an existential threat. https://www.canberratimes.com.au/story/6838483/climate-change-is-the-existential-crisis/?cs=14245

Global heating is turning cities into death traps

Cities Are Becoming Climate Death Traps    https://newrepublic.com/article/158537/cities-becoming-climate-death-traps  17 July 20  A new era of heat waves is here. We aren’t ready.    As the coronavirus pandemic continues throughout the United States, another deadly pandemic comes out to strike in the summer: extreme heat. Year after year, more people are dying because it’s simply too hot. As of right now, both this country and others lack even an accurate way of counting those deaths—let alone a comprehensive plan to reduce them. Thanks to climate change, it’s about to get much worse.

For the past week, the American South and Southwest have been experiencing record-breaking temperatures. The National Oceanic and Atmospheric Administration has predicted above-average heat for nearly the entire U.S. this summer. Unprecedented, early-summer heat waves roasted the Middle East in May and Siberia in June, setting the latter on fire. Arizona had its earliest-ever hundred-degree heat wave in April—and another 110 degree heat wave in May. Spain endured 105 degree heat this month.

When the heat index, a “feels-like” combination of temperature and humidity, reaches 104 degrees Fahrenheit indoors or out, human body temperature risks rising above the typical roughly 99 degrees Fahrenheit. When body temperature rises above 104 degrees, the consequences can be fatal within 30 to 60 minutes.

“Heat-related deaths are notoriously difficult to track because the role of heat isn’t always obvious. One 2017 study found that extreme heat can kill people in 27 different ways,” Juanita Constible, senior advocate, climate and health at the National Resources Defense Council, told me. “If someone dies of a heart attack during a heat wave, there’s a good chance that’s how their death will be recorded by officials, even if high temperatures were the trigger.”

Many scientists argue that official heat-death counts underestimate substantially. According to the World Health Organization, 166,000 people died due to heat waves between 1998 and 2017, but the true figure may be far higher. In the U.S., the Centers for Disease Control and Prevention only count deaths where heat illness is explicitly noted, so the official CDC count of heat-triggered deaths sits at just around 600 per year. Epidemiologists estimate that the real figure may be closer to 12,000—20 times higher than the official count.

Climate change is making heat waves longer, hotter, and more deadly. Scientists estimate that 80 percent of record-breaking heat waves would not have occurred without human-caused warming due to greenhouse gas emissions. And urban areas, in particular, face special risk of heat deaths because of the heat island effect, in which dark pavement, roofs, and concrete absorb additional heat, making temperatures much hotter than the reported weather in any given city.

In the U.S., heat deaths have more than doubled in Arizona in the last 10 years. Last year, a dangerous heat wave hit while storms left residents in the D.C. and New York City metro areas without power. Power outages can be deadly in a heat wave because without air conditioning, many people can’t cool off. In two heat deaths in a 2018 Arizona heat wave, the deceased were found indoors with a broken air conditioning unit that they couldn’t afford to fix.

“Some people won’t use their air conditioning because they’re afraid of the bills,” Patricia Solís, executive director of the Knowledge Exchange for Resilience at Arizona State University, told National Geographic. “They think they’re OK without it, but that’s how people die.”

“There are huge policy gaps in the U.S. with respect to extreme heat protections,” Rachel Licker, a senior climate scientist at the Union of Concerned Scientists, told me. “We found that without real action on climate change, by midcentury more than 250 cities across the U.S. are projected to experience 30 or more days with a heat index above 100 degrees Fahrenheit. This includes many cities that historically haven’t experienced this level of extreme heat.”

Forest fires raging over wide areas of the Brazilian Amazon

Dramatic footage fuels fears Amazon fires could be worse than last year
As dry season starts campaigners sound alarm over ‘shocking’ scale of fires, as Bolsonaro doubles down on denials,
Guardian, Dom Phillips in Rio de Janeiro, Sat 18 Jul 2020 Dramatic new images have shown fires raging over wide areas of the Brazilian Amazon nearly a year after blazes across the region sparked an international crisis for the far-right government of President Jair Bolsonaro.

The video images and photographs were filmed during a flight by Greenpeace over a wide area of forest in Mato Grosso state in the south of the Amazon on 9 July. Filmed just as the Amazon dry season was beginning, they raise fears that this year’s fires could be as devastating and perhaps worse than 2019’s.

“It was shocking to see the size of this deforestation and fires, at a time when the government is dismantling environment protection,” said Rômulo Batista, senior Amazon campaigner for Greenpeace, who spent days flying over a wide area. “It is the beginning of the dry season and we saw fires and areas being prepared for deforestation.”……….

official data shows the Brazilian government’s efforts so far this year have failed to bring results. Brazil saw more fires in the Amazon this June than in any year since 2007. Brazil’s space research agency INPE spotted 2,248, compared with 1,880 in June last year. Preliminary data showed deforestation from January to June, at 3,069 sq km, was 25% up on the same period last year. ……… https://www.theguardian.com/environment/2020/jul/17/dramatic-footage-fuels-fears-amazon-fires-could-be-worse-than-last-year

Siberia’s heat-wave – global heating is what made this possible

Siberia heatwave was ‘almost impossible’ without climate change, scientists say, SBS News 16 Jul 20, An extreme heatwave in the Arctic is a problem for the entire planet, say scientists, because the region regulates weather around the globe and contains much of the world’s carbon-rich permafrost.A recent heatwave in Siberia that saw temperature records tumble as the region sweltered in 38-Celsius highs was “almost impossible” without the influence of man-made climate change, leading climate scientists say.

An international team of researchers found that the record-breaking warm period was more than 2 degrees hotter than it would have been if humans had not warmed the planet through decades of greenhouse gas emissions.

The five hottest years in history have occurred in the last five years and there’s a better-than-even chance that 2020 will be the hottest ever recorded.

Earth’s poles are warming faster than the rest of the planet, and temperatures in Siberia – home to much of the world’s carbon-rich permafrost – were more than 5 degrees hotter than average between January and June. ………

‘Important for everyone’

The team behind the calculations stressed that the Siberian heatwave was a problem for the entire globe. Some 1.15 million hectares of forest going up in flames released millions of tonnes of CO2 into the atmosphere.

At the same time, the wildfires and sustained heatwaves accelerated the region’s permafrost melt. This caused an oil tank built on frozen soil to collapse in May, leading to one of the region’s worst-ever oil spills…….

The 2015 Paris climate deal commits nations to capping temperature rises to “well-below” 2 degrees above pre-industrial levels and to strive for a 1.5 degrees limit if at all possible. With just 1 degree of warming so far, Earth is already buffeted by record-breaking droughts, wild fires and super storms made more potent by rising sea levels.

To keep in line with the 1.5-degree target, the United Nations says global emissions must fall by 7.6 per cent every year this decade.

Sonia Seneviratne, from ETH Zurich’s Department of Environmental Systems Science, said the research showed the heatwave was an example of “extreme events which would have almost no chance of happening” without man-made emissions. https://www.sbs.com.au/news/siberia-heatwave-was-almost-impossible-without-climate-change-scientists-say

HEAT – Climate science must stop ignoring Southern Africa

Climate Science Has a Blind Spot When it Comes to Heat Waves in Southern Africa 

The lack of detailed information on extreme heat impacts hinders disaster response and preparedness.

BY BOB BERWYN, INSIDECLIMATE NEWS  13 July 20

Centered in the equatorial tropics, Africa is the world’s hottest continent, and millions of people there are facing a growing threat from deadly heat waves. But no one knows how many people have died or been seriously affected in other ways by extreme heat because the impacts have been poorly tracked.

Coordinated reporting is lacking and, at the global level, research and tracking of the impacts of climate change are biased toward developed countries, scientists concluded in a new study published Monday in the journal Nature Climate Change.

Africa is warming faster than the global average, and the lack of data is a roadblock to effective disaster preparation, assessment of vulnerability and planning for climate resilience, said co-author Friederike Otto, acting director of the University of Oxford Environmental Change Institute. She said she noticed the information gap when she reviewed the international disasters database (EM-DAT), for another recent study on extreme weather events in lower income countries. ………

Temperatures in southern Africa, with a population of 1.1 billion, have increased steadily over the last 70 years. Since 1990, the continent’s average temperature has increased at a rate of 0.65 degrees Fahrenheit per decade.

Because the region is so warm already, it doesn’t take much for temperatures to reach life-threatening levels. Research shows that heat waves have been increasing since at least 2000. The study shows obstacles faced by the least developed countries in Sub-Saharan Africa as they try to detect heat waves and their impacts, said Izidine Pinto, a climate researcher at the University of Cape Town who was not involved in the study. …..

Climate Justice

“Heat waves are one of the most deadly impacts of human-caused global warming in terms of lives,” Otto said. “It would be really important to highlight that in Africa.” 

She said the issue falls squarely into the realm of climate justice. One of the key obstacles to compiling useful heat wave data in southern Africa is weak governance in some countries, which can be traced back to a colonial legacy that destroyed and disempowered local cultures.

Developing countries in southern Africa contribute very little to human-caused warming in terms of emissions compared to the wealthy nations of North America, Europe and Asia, but they are among the hardest hit by its impacts. Per capita annual emissions in Sub-Saharan Africa are about 0.849 tons per person, according to the World Bank, compared to nine tons in Germany and 16 tons per capita annually in the United States………..

Finding Solutions

Otto said that researchers need to change the way climate science is done and who is doing it……….

Successful pilot projects are under way in Ghana and Gambia, where collaborations between local researchers, hospitals and epidemiologists are helping identify the direct health impacts of extreme heat, she said. That information can be combined with data on heat-related power outages and transport disruptions to further improve heatwave identification in sub-Saharan Africa.

In addition, more analysis of historical climate data from extreme heat periods is also needed, Otto wrote in a blog post for Carbon Brief accompanying the release of her new paper. That information combined with other data would help build effective early warning systems to save lives, Otto said.

“There is early warning on droughts, and other kinds of extremes, and they have improved a lot, but not really on heat wave warnings,” she added.

People in Africa are certainly aware of the growing number of heatwaves on the continent, said Mohamed Adow, Director of Power Shift Africa, a Nairobi-based climate and energy think tank. “But if they are not being recorded by scientists it will be much harder for African voices to be heard in the climate debate.” https://insideclimatenews.org/news/13072020/africa-heat-waves-climate-science

Nuclear power is excluded from European Commission’s strategies for a Green Deal

New EC ‘Green Deal’ strategies ignore nuclear power, Nuclear Engineering 13 July 2020  The European Commission (EC) on 8 July presented two strategies as part of its Green Deal –  “An EU Strategy for Energy System Integration”, and “A hydrogen strategy for a climate-neutral Europe”.The 21-page strategy for Energy System Integration aims to provide the framework for the green energy transition. The EC said: “The current model where energy consumption in transport, industry, gas and buildings is happening in ‘silos’ – each with separate value chains, rules, infrastructure, planning and operations – cannot deliver climate neutrality by 2050 in a cost efficient way; the changing costs of innovative solutions have to be integrated in the way we operate our energy system. New links between sectors must be created and technological progress exploited.”

There are three main pillars to this strategy:

  • First, a more ‘circular’ energy system, with energy efficiency at its core.
  • Second, a greater direct electrification of end-use sectors – a network of one million electric vehicle charging points will be among the visible results, along with the expansion of solar and wind power.
  • For those sectors where electrification is difficult, the strategy promotes clean fuels, including renewable hydrogen and sustainable biofuels and biogas. The Commission will propose a new classification and certification system for renewable and low-carbon fuels………..

To help deliver on this Strategy, the Commission announced the launch of the European Clean Hydrogen Alliance with industry leaders, civil society, national and regional ministers and the European Investment Bank. The Alliance will build up an investment pipeline for scaled-up production and will support demand for clean hydrogen in the EU.

“To target support at the cleanest available technologies, the Commission will work to introduce common standards, terminology and certification, based on life-cycle carbon emissions, anchored in existing climate and energy legislation, and in line with the EU taxonomy for sustainable investments.”

Neither of the reports made any mention of nuclear power either as part of energy system integration or as an energy source for the production of hydrogen. …

Antarctic glacier melting at an alarming rate

Climate change: what Antarctica’s ‘doomsday glacier’ means for the planet, 

Thwaites Glacier is melting at an alarming rate, triggering fears over rising sea levels Ft.com  Leslie Hook on the Antarctic Peninsula, Steven Bernard and Ian Bott in London , 13 Jul 20, 

 Even by the standards of Antarctica, there are few places as remote and hostile as Thwaites Glacier. More than 1,000 miles from the nearest research base, battered by storms that can last for weeks, with temperatures that hit -40C in winter, working on the glacier is sometimes compared to working on the moon.
 Dubbed the “doomsday” glacier, Thwaites, perhaps more than any other place in the world, holds crucial clues about the future of the planet. Only a handful of people had ever set foot on Thwaites before last year.
Now it is the focus of a major research project, led by British and American teams, as scientists race to understand how the glacier — which is the size of Britain and melting very quickly — is changing, and what that means for how much sea levels rise during our lifetimes.  ……
  understanding the Thwaites Glacier is not just academic — it is crucial for predicting how sea level rises will impact on cities, and how we should prepare for a radically different world. If Thwaites continues to deteriorate, then by the end of the century the glacier could be responsible for centimetres or tens of centimetres of sea level rise.
 “That doesn’t sound like much, but it is,” says David Vaughan, director of science at the British Antarctic Survey. “It is not about the sea coming up the beach slowly over 100 years — it is about one morning you wake up, and an area that has never been flooded in history is flooded.”

Antarctica holds around 90 per cent of the ice on the planet. It is equivalent to a continent the size of Europe, covered in a blanket of ice 2km thick. And as the planet heats up due to climate change, it doesn’t warm evenly everywhere: the polar regions warm much faster. It puts the icy continent of Antarctica and Greenland, the smaller Arctic region, right at the forefront of global warming. The South Pole has warmed at three times the global rate since 1989, according to a paper published last month.

As Antarctic ice melts and the glaciers slide toward the ocean, Thwaites has a central position, that governs how the other glaciers behave. Right now, Thwaites is like a stopper holding back a lot of the other glaciers in West Antarctica. But scientists are worried that could change. ……..

  Right now climate modellers say sea levels will rise between 61cm and 110cm by the end of the century, assuming the world keeps emitting carbon dioxide at current levels.

Impact of warming oceans The good news is that the Antarctic continent is not melting that much, yet. It currently contributes about 1mm per year to the sea level rise, a third of the annual global increase. But the pace of change at glaciers like Thwaites has accelerated at an alarming rate, even though it would take thousands of years for Antarctica itself to melt.

 As concentrations of carbon dioxide in the atmosphere increase to levels never before experienced by humans, researchers are trying to understand how the planet is changing.
Antarctica is central to that task. “Antarctica is by far the biggest risk,” in terms of extreme sea level rise, says Anders Levermann, a professor at the Potsdam Institute for Climate Impact Research, and the author of several papers on the Antarctic ice sheet.  https://www.ft.com/content/4ff254ed-960d-4b35-a6c0-1e60a6e79d91

The new normal for Northern Siberia – thawing permafrost,forests on fire

The Moscow Times reports economic losses from thawing permafrost alone is expected to cost Russia’s economy up to $2.3 billion US per year. Last year’s fires likely cost rural communities in the region almost $250 million US.   In March, Russia announced 29 measures it would be taking to try to deal with climate change over its vast landmass but critics complained the efforts have been more focused on exploiting natural resources in the Arctic than mitigating the impacts of a warming climate.

“They are actively going after every mineral and oil and gas deposit that they can,”

As permafrost thaws under intense heat, Russia’s Siberia burns — again,   https://www.cbc.ca/news/world/siberia-burning-climate-change-russia-1.5645428

Russia’s northern landscape is being transformed by heat and fire, Chris Brown · CBC News : Jul 12, Right around now, University of British Columbia climatologist and tundra researcher Greg Henry would usually be up at Alexandra Fiord on the central-east coast of Canada’s Ellesmere Island experiencing the Arctic’s warming climate up close.

Instead, the pandemic has kept his research team grounded in Vancouver — and his focus has shifted to observing the dramatic events unfolding across the Arctic ocean in northern Siberia.

“It’s remarkable — it’s scary,” said Henry of the incredible run of high temperatures in Russia’s far north that have been breaking records for the past month.

This week, a European Union climate monitoring project reported temperatures in June were up to 10 degrees higher than usual in some parts of Russia’s Arctic, with an overall rise of five degrees.

The heat and dry tundra conditions have also triggered vast forest fires. Currently, 1.77 million hectares of land are burning with expectations that the total fire area could eventually surpass the 17 million hectares that burned in 2019.

Equally striking is where the fires are burning.

“Now we are seeing these fires within 15 kilometres of the Arctic Ocean,” said Henry. “Usually there’s not much fuel to burn there, because it’s kept cold by the ocean so you don’t get ignition of fires that far north.”

This year though, he said the heat has dried the ground out enough to change the dynamics.

“It’s a harbinger of what we are in for because the Arctic has been warming at twice the rate of the rest of the planet.”

Lower-latitude oceans drive complex changes in the Arctic Ocean,

Arctic Ocean changes driven by sub-Arctic seas   https://www.eurekalert.org/pub_releases/2020-07/uoaf-aoc071020.php  b  UNIVERSITY OF ALASKA FAIRBANK  New research explores how lower-latitude oceans drive complex changes in the Arctic Ocean, pushing the region into a new reality distinct from the 20th-century norm.

The University of Alaska Fairbanks and Finnish Meteorological Institute led the international effort, which included researchers from six countries. The first of several related papers was published this month in Frontiers in Marine Science.

Climate change is most pronounced in the Arctic. The Arctic Ocean, which covers less than 3% of the Earth’s surface, appears to be quite sensitive to abnormal conditions in lower-latitude oceans.

“With this in mind, the goal of our research was to illustrate the part of Arctic climate change driven by anomalous [different from the norm] influxes of oceanic water from the Atlantic Ocean and the Pacific Ocean, a process which we refer to as borealization,” said lead author Igor Polyakov, an oceanographer at UAF’s International Arctic Research Center and FMI.

Although the Arctic is often viewed as a single system that is impacted by climate change uniformly, the research stressed that the Arctic’s Amerasian Basin (influenced by Pacific waters) and its Eurasian Basin (influenced by Atlantic waters) tend to differ in their responses to climate change.

Since the first temperature and salinity measurements taken in the late 1800s, scientists have known that cold and relatively fresh water, which is lighter than salty water, floats at the surface of the Arctic Ocean. This fresh layer blocks the warmth of the deeper water from melting sea ice.

In the Eurasian Basin, that is changing. Abnormal influx of warm, salty Atlantic water destabilizes the water column, making it more susceptible to mixing. The cool, fresh protective upper ocean layer is weakening and the ice is becoming vulnerable to heat from deeper in the ocean. As mixing and sea ice decay continues, the process accelerates. The ocean becomes more biologically productive as deeper, nutrient-rich water reaches the surface.

By contrast, increased influx of warm, relatively fresh Pacific water and local processes like sea ice melt and accumulation of river water make the separation between the surface and deep layers more pronounced on the Amerasian side of the Arctic. As the pool of fresh water grows, it limits mixing and the movement of nutrients to the surface, potentially making the region less biologically productive.

The study also explores how these physical changes impact other components of the Arctic system, including chemical composition and biological communities.

Retreating sea ice allows more light to penetrate into the ocean. Changes in circulation patterns and water column structure control availability of nutrients. In some regions, organisms at the base of the food web are becoming more productive. Many marine organisms from sub-Arctic latitudes are moving north, in some cases replacing the local Arctic species.

“In many respects, the Arctic Ocean now looks like a new ocean,” said Polyakov.

These differences change our ability to predict weather, currents and the behavior of sea ice. There are major implications for Arctic residents, fisheries, tourism and navigation.

This study focused on rather large-scale changes in the Arctic Ocean, and its findings do not necessarily represent conditions in nearshore waters where people live and hunt.

The study stressed the importance of future scientific monitoring to understand how this new realm affects links between the ocean, ice and atmosphere.

In 2020, a new radioological danger in Chernobyl

Chernobyl Is Again Close To A Disaster! What Happened There In 2020?  http://www.thesentrybugle.com/2020/07/chernobyl-is-again-close-to-disaster.html#.XwZuet3J6Vg.twitter    Ukrainian officials have sought calm after forest fires in the restricted zone around Chernobyl, scene of the world’s worst nuclear accident, led to a rise in radiation levels.

Firefighters said they had managed to put out the smaller of two forest fires that began at the weekend, apparently after someone began a grass fire, and had deployed more than 100 firefighters backed by planes and helicopters to extinguish the remaining blaze.
The fire had caused radiation fears in Kyiv, Ukraine’s capital, which is located about 60 miles south of the Chernobyl exclusion zone. Government specialists on Monday sent to monitor the situation reported that there was no rise in radiation levels in Kyiv or the city suburbs.
“You don’t have to be afraid of opening your windows and airing out your home during the quarantine,” wrote Yegor Firsov, head of Ukraine’s state ecological inspection service, in a Facebook post about the results of the radiation tests.
As of Monday afternoon, the country’s emergency ministry said that the remaining fire in the Chernobyl Exclusion Zone covered about 20 hectares and was still being extinguished. Footage released by the ministry showed firefighters dousing flames on the forest floor, and clouds of smoke rising.
Police have arrested a suspect believed to have caused the blaze, a 27-year-old man from the area who reportedly told police he had set grass and rubbish on fire in three places “for fun”. After he had lit the fires, he said, the wind had picked up and he had been unable to extinguish them.
An earlier post by Firsov had warned about heightened radiation levels at the site of the fire, which he said had been caused by the “barbaric” practice of local grass fires often started in the spring and autumn. “There is bad news – radiation is above normal in the fire’s center,” Firsov wrote on Sunday.
The post included a video with a Geiger counter showing radiation at 16 times above normal. The fire had spread to about 100 hectares of forest, Firsov wrote.
The country’s emergency ministry put out a warning for Kyiv on Monday about poor air quality but said it was related to meteorological conditions, and not to the fire.
The service had said on Saturday that increased radiation in some areas had led to “difficulties” in fighting the fire while stressing that people living nearby were not in danger. On Monday, it said that gamma radiation levels had not risen near the fire.
Chernobyl polluted a large area of Europe when its fourth reactor exploded in April 1986, with the region immediately around the power plant the worst affected. People are not allowed to live within 30km of the power station.
The three other reactors at Chernobyl continued to generate electricity until the power station finally closed in 2000. A giant protective dome was put in place over the fourth reactor in 2016.
Fires are common in the forests near the disused power plant.

Climate change’s big problem – there’s no quick fix

There’s no quick fix for climate change  https://www.theverge.com/21315822/climate-change-global-temperature-study-decades-fixScientists looked for a ‘shortcut’ and didn’t find one

By Justine Calma@justcalma  Jul 7, 2020,  It could take decades before cuts to greenhouse gases actually affect global temperatures, according to a new study. 2035 is probably the earliest that scientists could see a statistically significant change in temperature — and that’s only if humans take dramatic action to combat climate change.
Specifically, 2035 is the year we might expect to see results if we switch from business-as-usual pollution to an ambitious path that limits global warming to under 2 degrees Celsius — the target laid out in the Paris climate agreement. The world isn’t on track to meet that goal, so we might not see the fruits of our labor until even later. That means policymakers need to be ready for the long haul, and we’re all going to need to be patient while we wait for the changes we make now to take effect.

“I foresee this kind of train wreck coming where we make all this effort, and we have nothing to show for it,” says lead author of the study, Bjørn Samset. “This will take time.”

It will be time well spent if we manage to cut emissions — even if we have to wait to see results. Humans have so far warmed up the planet by about 1 degree Celsius. That’s already come with more devastating superstorms and wildfires and has forced people from Louisiana to Papua New Guinea to abandon their homes as rising sea levels flood their lands. Even keeping the planet to the 2 degree goal would result in the near annihilation of the world’s coral reefs. Taking into consideration all of the commitments from world leaders to work together on climate change, we’re currently careening toward global warming of about 3 degrees Celsius above preindustrial levels.

To avoid burnout and keep aspirations high when it comes to tackling climate change, scientists and policymakers will need to be realistic about what’s ahead. The first line of the new study, published today in the journal Nature Communications, reads: “This paper is about managing our expectations.”

The study looks at the effects of cutting down on carbon dioxide, black carbon, and methane emissions. Carbon dioxide is the toughest greenhouse gas to tackle because so much of the world economy still relies on burning fossil fuels.

Methane (a more potent greenhouse that comes from agriculture and natural gas production) and black carbon (a big component of soot) are, in theory, easier to cut back. Using climate models and statistical analysis, Samset and his colleagues wanted to know whether addressing these other pollutants might lead to faster results. Their analysis isolated the effects that reducing methane and black carbon might have. They found that temperatures might respond quicker to axing these pollutants, but it wouldn’t have as big of an effect in the long term as pushing down our carbon emissions. The best bet is to tackle all three at once.

“We kind of break this apart and try to see, is there a shortcut? Is there anything we can do to give people the impression that things are having an effect? And unfortunately, the answer is no,” says Samset. “There’s no quick fix to this.”

Part of the problem is that carbon dioxide can persist in the atmosphere for hundreds of years after being released by burning coal, oil, and gas. Natural variations in climate can also delay the impact that cutting down greenhouse gases has on global temperatures.

“There is this fundamental misunderstanding of the climate system by non climate scientists trying to use trends on a 10 year time scale for climate change, when [with] climate change a 100 or 200-year timescale is relevant,” explains Natalie Mahowald, a climate scientist at Cornell University who was not involved in the study.

“All our hard work today, we will not be able to see for 20 or 30 years — this is the crux of the problem,” Mahowald says. “Humans have a really hard time doing something for future generations.”

Climate change is seriously hitting women, right now

Climate woes growing for women, hit worst by displacement and migration

by Megan Rowling | @meganrowling | Thomson Reuters Foundation, Tuesday, 7 July 2020 

Extreme weather and rising seas are increasing the burden of work, ill-health and violence faced by women who are forced to leave home or left behind as menfolk seek jobs elsewhere

BARCELONA, – From sexual violence in displacement camps to extra farm work and greater risk of illness, women shoulder a bigger burden from worsening extreme weather and other climate pressures pushing people to move for survival, a global aid group said on Tuesday.

Scientists expect forced displacement to be one of the most common and damaging effects on vulnerable people if global warming is not limited to an internationally agreed aim of 1.5 degrees Celsius, CARE International noted in a new report.

“This report shows us that climate change exacerbates existing gender inequalities, with women displaced on the frontlines of its impacts bearing the heaviest consequences,” said CARE Secretary General Sofia Sprechmann Sineiro.

For example, women and girls uprooted by Cyclone Idai, which hit Mozambique, Zimbabwe and Malawi in 2019, are still facing serious health threats due to poor access to basic services and sanitary products, the report said.

And in Ethiopia, where about 200,000 people were forced from their homes last year by drought and floods, women living in overcrowded shelters face higher levels of sexual violence there and on longer, more frequent trips to fetch water and firewood.

Sven Harmeling, CARE’s global policy lead on climate change and resilience, said displacement linked to climate stresses was already “a harsh reality for millions of people today”.

If global warming continues at its current pace towards 3C or more above pre-industrial times, “the situation may irrevocably escalate and evict hundreds of millions more from their homes”, he added.

Climate change impacts are likely to strengthen and “unfold over the next couple of years, and not only in the distant future”, he told the Thomson Reuters Foundation.

Failure to prepare for them will lead to more suffering and people having to abandon their land, he said. Many places already are affected by multiple climate shocks and rising seas, making it harder for those displaced to return, he added.

“(Climate extremes) may mean more men are leaving to try to find income elsewhere, and that puts additional burden on the women who stay back and have to try to earn (money) while taking care of the family,” he said. ……….

In most countries, climate measures supported by public finance do not adequately prioritise women, CARE noted, calling for at least 85% of funding for adaptation projects to target gender equality as an explicit objective by 2023 at the latest.

But some projects are making women a priority, it said……… https://news.trust.org/item/20200707051425-a5d5v/
