Worst-case climate scenario fades, warming does not
- The worst-case climate scenario predicting over 4 degrees Celsius warming by 2100, known as RCP8.5 and SSP5-8.5, is now considered less probable due to faster renewable energy adoption and emissions controls.
- Despite this decline, the world is still likely to exceed 1.5 degrees Celsius warming temporarily and could reach about 3 degrees Celsius by the end of the century, worsening heatwaves, droughts, floods, crop failures, and sea level rise affecting millions.
- The United Nations General Assembly endorsed a non-binding resolution supporting international legal obligations for countries to combat climate change, despite opposition from the US, Russia, Iran, and Saudi Arabia.

The glimmers of hope should push us to accelerate our efforts, not to slow them down.
The World Climate Council has withdrawn its extreme scenario for global warming as "unplausible." Can one now try to switch from panic mode to pragmatism in terms of climate protection?

LatestlyWorst-case climate scenario fades, warming does not
For years, a worst-case climate scenario served as a stark warning of what could happen if the world failed to curb fossil fuel use. A temperature rise of more than 4 degrees Celsius (7.2 Fahrenheit) by the end of the century would bring with it catastrophic consequences including deadly heatwaves, rising seas, crop failures and mass displacement. But a scientific paper published last month says that doomsday pathway — known as RCP8.5 and later …
A scenario with extremely high CO2 emissions has long been considered implausible in professional circles. Now it is put to the record. However, the concerns about the climate are not dealt with.
The worst and the best possible scenario is off the table. What this means is explained by SRF rector Klaus Ammann.
IPCC Retires Its Most Implausible Global Warming Scenarios
"New and improved" climate models are offered, but the 'plausibility vacuum' remains. Furthermore, IPCC fails to acknowledge the damage to society and science done by its previous assessments. The post IPCC Retires Its Most Implausible Global Warming Scenarios first appeared on Le·gal In·sur·rec·tion.
