About The Event

Through launch of the 50x30 Coalition, this event aims to inform and engage leaders to act on the results of the IPCC Special Reports on 1.5°C of Warming (SR1.5, 2018) and on the Ocean and Cryosphere in a Changing Climate (SROCC, 2019), as well as science to be included in the Sixth Assessment Report (AR6, 2021).


50x30 aims to highlight the damaging global impacts of “overshoot”, in which emissions remain too high to hold the Earth within 1.5°, or at least 2°C of warming: the temperature goal of the Paris Agreement. The consequences of overshoot are dangerously underestimated by the policy world. While there are other impacts from exceeding Paris limits, those from cryosphere standout, nearly all with global consequences that cannot be reversed on human timescales: unstoppable long-term sea-level rise, polar ocean acidification, loss of glacier- and snow-fed water resources, centuries-long permafrost carbon emissions.
 

Most governments and many businesses have pledged carbon neutrality by 2050; but the IPCC SR1.5 made clear that median global reductions of 50% are needed by 2030 to reach that neutrality goal; and almost no actors are doing so. 50x30 will raise up the policy plans of thosefew that do; making clear both that 1.5°C remains possible, and what will happen if we fail.


Speakers include IPCC scientists and 50x30-consistent governments who have endorsed the 50x30 Mission Statement.

Background

50x30 is a partnership between cryosphere and climate science research institutions, and those governments that have meaningful 50% by 2030 reduction targets. Founding scientific institutions include the Bolin Centre for Climate Research/Stockholm University (Sweden), Grantham Institute of Climate and Environment at Imperial College London (UK), University of Massachusetts-Amherst (U.S.), Bristol University Glaciology Centre (UK), the Antarctic Research Centre/University of Victoria Wellington (New Zealand), American Geophysical Union (AGU), National Snow and Ice Data Center (NSIDC, U.S.), and Climate Analytics (Germany). Governments with 50x30 consistent targets include COP-26 host the United Kingdom, Denmark, Finland, Germany and Sweden. The International Crysophere Climate Initiative (ICCI, Sweden/U.S.) provides administrative support. 50x30 is made possible through foundation support from the Svenska Postkodsstiftelsen.
