What strikes me is the relative sharp change. CO2 has been rising since, what 250 years ? However real effects of global warming seems to be felt since, like 10 years old ?

That’s very characteristic of highly nonlinear systems, and weather/climate is the textbook nonlinear system.

The year-to-year fluctuations are much stronger than the overall trend. We notice only the record-breaking years and then we feel like the change occurred in the past year.

CO2 and temperature track quite well. However, climate sensitivity actually says the relationship is not linear but logarithmic. Doubling CO2 increases temperature by 2-3 degrees.

The thing is, in the last decade or two we have firmly moved into the regime where we are out of the natural variability. If you get a 30 degree summer every five years instead of every ten that might be a very clear signal for warming, but is not as notable. If every summer is 30 degree and sometimes you get 40 you really feel the new climate normal.

It has been rising exponentially.

Look up glacier timelapses. More vulnerable ecosystems have visibly reflected climate change for far longer than 10 years now.

Atmospheric CO2 has been accelerating. We increased atmospheric CO2 by as much the last 25 years as we did the preceding century.

Keep in mind total emissions grew much much faster in our lifetime (let’s say 1980-2026) than in the prior 200 years, which was before most of the recent huge growth in Chinese and Indian emissions.

Also the ocean and arctic were absorbing the majority of the heat. The arctics been going through these heat waves for 10 years, its white albedo decreasing and potentially permafrost melting making more effective emissions now.

We must act. Stop eating beef. Stop taking trips if possible. Vote for those who care about climate, not bugaboos like immigration. We have real problems like climate, and jump-scare tribal problems like immigrants and foreigners, which are actually good for a nation.

Saying this just having emerged from a heat dome, New England forest is not built for feels like 105F. Many living things in my own backyard are now heavily stressed by climate. We. Must. Act.

> CO2 has been rising

it rises faster now because we have more co2-emitters today than we did 20 years ago. source: economy has grown. idc if this sounds rude, but honestly you shoulve guessed this
