@unep.org report on Limiting Overshoot: There are no good outcomes in overshooting and remaining above 1.5°C We need rapid near-term action to limit overshoot magnitude and duration and the damage it will cause for people and the Earth – including the cryosphere www.unep.org/resources/li... ❄️🧪🌊

If you want 1.5C, 1.8C, 2C, overshoot, no-overshoot, etc, then they all require the same thing: rapid short-term emission reductions reaching net zero CO2 emissions as soon as possible. This has been clear from the IPCC Special Report on 1.5C, which depicts "overshoot" on its cover! 1/

In Nepal, it will most likely take months for scientists to understand exactly what led to deadly flash floods that killed over 1,000 people and left thousands missing. Early theories posit glacier meltwater and a thawing permafrost could have contributed to bedrock collapse.

Deadly Flash Floods in Nepal Most Likely Caused by Weakened Bedrock
As the planet warms, glacier meltwater and a thawing permafrost could have contributed to destabilizing the rock.

Under the banner of ‘Friends of Science’, in an overflowing press conference at SB64, diplomats from Fiji, Nepal, the EU, Switzerland, Sierra Leone and Panama vowed to ensure that decision-making in the UN climate process remains based on the “best available science”. @climatechangenews.com 🔗 ⬇️

Yesterday, ICCI had the privilege of co-moderating two sessions at the Dialogue on Mountains and Climate Change at #SB64. Mountains are of global importance. Their glaciers and snowpack regulate river flow, support agriculture and livelihoods, and store freshwater that billions of people depend on.
