Chat-GPT, what does a four degrees C world mean for life on earth? DALL-E, can you paint that?

“A four degrees Celsius increase in global average temperature above pre-industrial levels would likely have catastrophic and irreversible impacts on life on Earth. This level of warming would be considered as a “Hothouse Earth” scenario, beyond which the impacts of global warming would be difficult or impossible to adapt to, and would lead to the collapse of human civilizations and the extinction of many species.

Some of the potential impacts of a 4 degrees C world include:

Widespread desertification and loss of agricultural productivity, leading to food shortages and famines.

Widespread extinction of plant and animal species, with a significant loss of biodiversity

Widespread flooding of coastal areas and small islands due to rising sea levels

Increased frequency and intensity of extreme weather events leading to increased destruction of infrastructure and human settlements

Disruption of the global water cycle, leading to droughts, floods and water scarcity

Disruption of the global climate system, leading to unpredictable and extreme weather patterns.

In summary, a four degrees Celsius increase in global average temperature would have catastrophic and potentially irreversible impacts on life on Earth, and would have devastating consequences for human societies and the natural world. It is important to note that this scenario should be avoided at all costs and immediate actions need to be taken in order to mitigate greenhouse gas emissions.”

Meanwhile…
“Most analyses (including IPCC scenarios) indicate that limiting warming to 1.5°C requires global greenhouse gas emissions to peak before 2025 and be halved by 2030.” https://lnkd.in/dmyviQEX

IF it peaks, we then have five years after that to halve it. That’s five COPs, barely a political cycle. Is achieving that probable, plausible, possible or preposterous?
