The state of knowledge regarding trends and an understanding of their causes is presented
for a specific subset of extreme weather and climate types. For severe convective storms …

In late June 2021 a heatwave of unprecedented magnitude impacted the Pacific Northwest
region of Canada and the United States. Many locations broke all-time maximum …

The AR5 concluded that human influence on the climate system is clear, evident from
increasing greenhouse gas concentrations in the atmosphere, positive radiative forcing …

For generations, climate scientists have educated the public that 'weather is not climate', and
climate change has been framed as the change in the distribution of weather that slowly …

Although anthropogenic climate change is expected to have caused large shifts in
temperature and rainfall, the detection of human influence on global drought has been …

Climate models have continued to be developed and improved since the AR4, and many
models have been extended into Earth System models by including the representation of …

This chapter assesses the causes of observed changes assessed in Chapters 2 to 5 and
uses understanding of physical processes, climate models and statistical approaches. The …

A changing climate can lead to changes in the frequency, intensity or duration of an extreme
event, or result in an 3 unprecedented, previously unobserved, extreme. As well, a weather …

Global warming increases available sensible and latent heat energy, increasing the
