“The report provides new estimates of the chances of crossing the global warming level of 1.5°C in the next decades, and finds that unless there are immediate, rapid and large-scale reductions in greenhouse gas emissions, limiting warming to close to 1.5°C or even 2°C will be beyond reach.
The report shows that emissions of greenhouse gases from human activities are responsible for approximately 1.1°C of warming since 1850-1900, and finds that averaged over the next 20 years, global temperature is expected to reach or exceed 1.5°C of warming. This assessment is based on improved observational datasets to assess historical warming, as well progress in scientific understanding of the response of the climate system to human-caused greenhouse gas emissions.”—IPCC 2021
The Cambridge Centre for Climate Science and Cambridge Zero invite you to a panel discussion about the recently published IPCC Working Group I report, Climate Change 2021: the Physical Science Basis. You will hear short summaries of the reports from IPCC authors and join in the debate.
