This episode will explore the science behind climate prediction. Topics will include the differences between weather, climate variability and climate change; climate models; the Coupled Model Intercomparison Project (CMIP); climate model ensembles; the accuracy and reliability of climate prediction; and projections for global warming at the end of the century.
Discover the science behind why our planet is warming and the climate is changing. Learn what needs to be done to mitigate climate change.
There is an overwhelming international scientific consensus on the following three points:
1) Over the past 120 years the Earth has been warming and the climate has been changing at alarming rates.
2) Global warming and the resulting global climate change over the past 120 years have been driven almost exclusively by the Earth’s greenhouse effect and the accumulation of greenhouse gases in the atmosphere caused by human activities.
3) Without dramatic reduction in the emission of greenhouse gases into the atmosphere, the Earth will continue to warm, and the climate will continue to change to the detriment of humankind.
Stated simply: rapid climate change is happening, humans are causing it, and it is not a good thing. Indeed, humanity is facing a climate crisis.
