Earth is heading for 2.7°C warming this century. We may avoid the worst climate scenarios – but the outlook is still dire.

 Is climate action a lost cause? The United States is withdrawing from the
Paris Agreement for the second time, while heat records over land and sea
have toppled and extreme weather events have multiplied.

In late 2015,
nations agreed through the Paris Agreement to try to hold warming well
under 2°C and ideally to 1.5°C. Almost ten years later, cutting emissions
to the point of meeting the 1.5°C goal looks very difficult. But humanity
has shifted track enough to avert the worst climate future.

Renewables,
energy efficiency and other measures have shifted the dial. The worst case
scenario of expanded coal use, soaring emissions and a much hotter world is
vanishingly unlikely. Instead, Earth is tracking towards around 2.7°C
average warming by 2100. That level of warming would represent
“unprecedented peril” for life on this planet. But it shows progress is
being made.
