No credible scientist advocates mitigation only. I know many of them.

Mitigation is about the immediate weather incidents accompanying the climate crisis. Mitigation is immediate survival and offers no solution to end the crisis. Ending the climate crisis is paramount to the outcomes of current generations and those to come. A crisis is meant to be ended. 

STOP GREENHOUSE EMISSIONS!

The world is at risk of descending into a climate “doom loop”, a thinktank report has warned. (click here)

It said simply coping with the escalating impacts of the climate crisis could draw resources and focus away from the efforts to slash carbon emissions, making the situation even worse.

The damage caused by global heating across the globe is increasingly clear, and recovering from climate disasters is already costing billions of dollars. Furthermore, these disasters can cause cascading problems including water, food and energy crises, as well as increased migration and conflict, all draining countries’ resources.

The researchers, from the Institute for Public Policy Research (IPPR) and Chatham House, said a current example of the impact of the climate crisis complicating efforts to reduce emissions and other action was the debate over whether keeping the global temperature rise below 1.5C – the international goal – was still possible.

Those arguing 1.5C was still possible risked perpetuating complacency that today’s slow pace of action was sufficient, the researchers said, while those arguing it was not possible risked supporting fatalism that little that could now be done, or “extreme approaches” such as geoengineering.

Avoiding a doom loop required a more honest acceptance by politicians of the great risks posed by the climate crisis, the researchers said, including the looming prospect of tipping points and of the huge scale of the economic and societal transformation required to end global heating. This should be combined with narratives that focused on the great benefits climate action brought and ensuring policies were fairly implemented....

Climate Tipping Points should be observed and reported on regularly.

.

Climate tipping points are conditions beyond which changes in a part of the climate system become self-perpetuating. These changes may lead to abrupt, irreversible, and dangerous impacts with serious implications for humanity. Armstrong McKay et al. present an updated assessment of the most important climate tipping elements and their potential tipping points, including their temperature thresholds, time scales, and impacts. Their analysis indicates that even global warming of 1°C, a threshold that we already have passed, puts us at risk by triggering some tipping points. This finding provides a compelling reason to limit additional warming as much as possible. —HJS
