What ChatGPT answers to how the world looks like at 4°C increase of the average temperture

Writer: DirkDirk

In France, ministers seems to prepare the public about a 4°C increase of the mean temperature of Earth. They seem to think that it will not be that bad and may minimize the real effects. 



If Earth's mean temperature increases by 4°C compared to pre-industrial levels, the planet would experience drastic and potentially catastrophic changes. 



🌎 Global Changes


More extreme weather: Intense hurricanes, heatwaves, droughts, and floods would become the norm.



Sea level rise: Oceans could rise up to 1 meter (3 feet) or more, submerging coastal cities like Miami, Jakarta, and parts of London.



Unlivable heat: Some regions (e.g., parts of the Middle East, South Asia) could face temperatures above 50°C (122°F) regularly, making them nearly uninhabitable.



❄️ Melting Ice & Rising Seas


Arctic ice and glaciers in Greenland & Antarctica would be in catastrophic decline, contributing heavily to sea level rise.


The Amazon Rainforest could collapse, turning into dry savannah due to increased heat and droughts.



🌿 Biodiversity Crisis


50% or more of species could face extinction due to habitat loss, ocean acidification, and extreme climate conditions.


Coral reefs, including the Great Barrier Reef, would likely die off completely due to severe bleaching.



🍽️ Food & Water Shortages


Agricultural failures would be widespread, with reduced crop yields in many regions, leading to global food crises.


Freshwater supplies would dwindle, particularly in regions relying on glaciers and seasonal rains.



🏙️ Human Impacts


Mass migrations: Hundreds of millions of people could be displaced from coastal and unlivable regions.


Health crises: More heat-related deaths, the spread of tropical diseases, and worsening air pollution.


Economic instability: Infrastructure damage, resource shortages, and forced migrations would cause major financial crises worldwide.



🔥 Worst-Case Scenario


If feedback loops (like methane release from permafrost) accelerate, runaway climate change could make parts of the planet inhospitable for humans.


This is why scientists urge keeping warming below 1.5°C-2°C to avoid catastrophic tipping points. A 4°C warmer world would be unrecognizable from today’s Earth.



This is what ChatGPT answers you. Are you ready?
