thanks to brilliant for sponsoring a section of this video I have a cold by the way scientists keep making predictions that the world will warm by one or two or three or however many degrees it is in 30 years time but why do they keep making these predictions if none of them have been correct so far you may remember climate scientist James Hansen f...

Questions & Answers

Q: Why do climate scientists keep making predictions about global warming if none of them have been correct so far?

Climate scientists continue to make predictions because recent analyses show that their predictions have been largely accurate. The misconception that none of them have been correct arises from deliberate misrepresentation of the most extreme predictions.

Q: How do climate scientists ensure the accuracy of their predictions?

Climate scientists use ensembles of computer models, each representing different aspects of the Earth's system, to create statistical models. While no single model is correct, combining them provides a more accurate representation and allows for consistent predictions.

Q: Why do some people still doubt climate change predictions?

There are several reasons for skepticism, including the intentional misrepresentation of predictions by those with vested interests in maintaining the current fossil fuel-based system. Additionally, humans tend to accept information that aligns with their existing beliefs, leading to motivated reasoning.

Q: How do climate change predictions affect our future?

Climate change predictions inform us about the potential impacts of global warming, such as more extreme weather events and rising temperatures. Taking action based on these predictions can help mitigate the worst effects and create a more sustainable future.

Summary & Key Takeaways

  • Scientists analyzed computer models used in climate change predictions and found them to be accurate in predicting global temperature increase from 2004 to 2020.

  • Older predictions from the 1970s were also largely accurate, despite being less sophisticated.

  • Climate scientists use ensembles of models to create robust statistical representations of reality, combining different models to make predictions.
