\nClimate Change, Acceleration, and Inertia: 4\u20137\u00b0C of Warming<\/p>\n
Climate change is not simply a matter of temperatures gradually rising.<\/p>\n
It is an energy problem.<\/p>\n
More energy is entering the climate system than leaving it\u2014and most of that excess energy is being absorbed by the oceans.<\/p>\n
That creates INERTIA.<\/p>\n
But something else is happening.<\/p>\n
As warming crosses critical thresholds, self-reinforcing feedbacks become increasingly active:<\/p>\n
\ud83d\udd25 Warming \u2192 \ud83d\udca7 More Water Vapor \u2192 \ud83d\udd25 More Warming \u21ba<\/p>\n
\u2601\ufe0f Fewer Low Clouds \u2192 \u2600\ufe0f More Energy Absorbed \u2192 \ud83d\udd25 More Warming<\/p>\n
\ud83d\udfe0 More Tropospheric Ozone \u2192 \ud83c\udf0e Stronger Greenhouse Effect \u2192 Faster Carbon-Cycle Response<\/p>\n
These feedbacks don\u2019t operate independently. They interact, couple, and reinforce one another.<\/p>\n
That changes the mathematics of climate change.<\/p>\n
The 1.5\u00b0C threshold is not simply a number on a thermometer. It is a tripwire for a climate system increasingly dominated by feedbacks and nonlinear responses.<\/p>\n
The result is a new climate reality:
\nACCELERATION + COUPLING + INERTIA<\/p>\n
The question is no longer simply how much greenhouse gas humans emit. It is how quickly the climate system begins amplifying the warming we have already created.<\/p>\n
Having tripped the 1.5\u00b0C tripwire, both the acceleration and inertia of climate change have created a new reality. The most likely scenario is global warming of approximately 4\u00b0C this century. If humanity does not reach net zero by 2035, approximately 4\u20137\u00b0C of warming by 2150 becomes the most likely scenario.<\/p>\n
