The 50×30 coalition is an alliance between cryosphere and emissions research institutions, and governments that have accepted the scientific necessity to reduce emissions 50% by 2030; in order to prevent cascading and irreversible damage, on a planetary scale, from the impact of greenhouse gas emissions on the cryosphere.
Because of cryosphere, carbon neutrality by 2050 is not enough: the way we get there matters. Overshoot of the 1.5°C goal cannot be considered a viable or safe option, from either an economic or social standpoint. This is because much of the Earth’s polar and mountain regions – whether glaciers, snowpack, permafrost, sea ice, polar oceans and seas, or the great polar ice sheets – react directly to peaks in temperature and carbon dioxide emissions.

STOCKHOLM: With impacts from climate change threatening to be as abrupt and far-reaching in the coming years as the current pandemic, leading scientists have released a compilation of the 10 most important insights on the climate from the last year to help inform collective action on the ongoing climate crisis.
In a report presented today to Patricia Espinosa, Executive Secretary of the United Nations Framework Convention on Climate Change (UNFCCC), report authors outlined some of 2020 s most important findings within the field of climate science, ranging from improved models that reveal the need for aggressive emission cuts in order to meet the Paris Agreement to the growing use of human rights litigation to catalyze climate action.
