Our team has summarised the findings of the latest IPCC report on climate science
1. Our understanding of the climate system has only continued to strengthen in the last six years. Ocean and air temperature are rising, mass from glaciers and ice sheets is being lost, and sea level is rising.
2. Scientists are more certain than ever that increasing global temperatures since 1950 have been caused primarily by human activities.
3. A warming climate is increasing the frequency and severity of many extreme weather events and is changing rainfall patterns, creating risks for human well-being, the economy and the environment.
4. Stabilising the climate system will require substantial and sustained reductions of carbon dioxide (CO2) emissions. We will have to decarbonise the economy.
