Timber! or: Living in timber cities could avoid emissions…

(Photo by Sarah Worth ) Press release by the Potsdam Institute for Climate Impact Research (PIK) 08/30/2022 Living in timber cities could avoid emissions – without using farmland for wood production Transition to timber cities could avoid more than 100 billion tons of CO2 emissions by 2100– about 10% of the remaining CO2 budget for the 2°C climate target. Wood needed is sourced from natural forests and timber plantations … Read more Timber! or: Living in timber cities could avoid emissions…

Considering catastrophe: high-impact, low-probability climate scenarios “dangerously underexplored”

08/02/2022 Press release by the Potsdam Institute for Climate Impact Research (PIK) Researchers call for a new “Climate Endgame” agenda and say far too little work has gone into understanding the mechanisms by which rising temperatures might pose a “catastrophic” risk to society and humanity: For instance, if temperature rises are worse than many predict or cause cascades of events we have yet to consider, or indeed both. The … Read more Considering catastrophe: high-impact, low-probability climate scenarios “dangerously underexplored”

Today’s children to experience two to seven times more extremes than their grandparents

Press release by the Potsdam Institute for Climate Impact Research (PIK) 09/27/2021 Today’s children will be hit much harder by climate extremes than today’s adults, researchers show in the leading journal Science. During their lifetime, a child born in 2021 will experience on average twice as many wildfires, between two and three times more droughts, almost three times more river floods and crop failures, and seven times more heatwaves … Read more Today’s children to experience two to seven times more extremes than their grandparents

The Gulf Stream May Be Dying

via The Potsdam Institute for Climate Impact Research (PIK) : Major Atlantic ocean current system might be approaching critical threshold The major Atlantic ocean current, to which also the Gulf stream belongs, may have been losing stability in the course of the last century. This is shown in a new study published in Nature Climate Change. The Atlantic Meridional Overturning Circulation, or AMOC, transports warm water masses from the … Read more The Gulf Stream May Be Dying

Few realistic scenarios left to limit global warming to 1.5°C

Press release by the Potsdam Institute for Climate Impact Research (PIK) Few realistic scenarios left to limit global warming to 1.5°C in line with the Paris Agreement. All levers must be pulled, some to a challenging level, to achieve this ambitious climate target. These levers include the energy system but also for instance land-use. Unrealistically optimistic scenarios tend to over-estimate e.g. carbon capture and storage potentials. 05/14/2021 Of … Read more Few realistic scenarios left to limit global warming to 1.5°C
