Hannah Ritchie argues that the 1.5-degree Celsius climate target is no longer feasible due to the immense challenge of required emissions reductions. However, she emphasizes that striving for even slight increases in temperature, like 1.6 or 1.7 degrees, can mitigate risks associated with climate change. While she believes keeping global warming below two degrees is still achievable, it requires ambitious actions across four key sectors: energy, transport, food, and construction, entailing a shift toward renewable and low-carbon energy sources.
I tend to think that the 1.5 degree target is no longer feasible. The scale and pace of emissions reductions needed is probably out of reach.
For every increment of warming, the risk of climate change increases. We need to fight for 1.6, 1.7 and 1.8 because it reduces risks.
It's feasible to keep temperatures below two degrees. If countries achieve their targets, we could possibly sneak just under two degrees.
Key areas to target in solving climate change include energy, transport, food, and construction, focusing on transitioning to low carbon energy sources.
