The hefty report, State of the Climate in 2015, was produced by more than 450 scientists from 62 countries around the world — more than any previous edition.

Every single direct indicator of temperature described in the report leaves no doubt that 2015’s global surface temperature towered over any year preceding it. Numerous other climate indicators related to temperature exhibited characteristics consistent with such historic warmth.

2015’s exceptional warmth was fueled by a record-challenging El Niño event, in which warmer-than-normal tropical Pacific Ocean waters infused heat into the atmosphere, and by record-setting concentrations of heat-trapping gases from human activity.

Here are the 10 most impressive findings from this report:

1. The global temperature was the highest on record…….

2. The average ocean surface temperature was warmest on record…..

3. Upper ocean heat content was highest on record…..

4. Global sea level was highest on record…..

5. The El Niño event was among the strongest on record……

6. Greenhouse gases were highest on record……

7. Record number of major tropical cyclones in Northern Hemisphere…….

8. Arctic sea ice had its lowest maximum extent……

9. Glaciers continued shrinking….

10. Extreme temperatures were most extreme on record……

The report is available online and will be published by the Bulletin of the America Meteorological Society. https://www.washingtonpost.com/news/capital-weather-gang/wp/2016/08/02/the-10-most-startling-facts-about-climate-in-2015-the-warmest-year-on-record/
