Arctic amplification (AA)—referring to the enhancement of near-surface air temperature
change over the Arctic relative to lower latitudes—is a prominent feature of climate change …

The ambition and effectiveness of climate policies will be essential in determining
greenhouse gas emissions and, as a consequence, the scale of climate change impacts …

Previous studies have identified a recent increase in wildfire activity in the western United
States (WUS). However, the extent to which this trend is due to weather pattern changes …

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 …

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 …

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 …

Despite a steady increase in atmospheric greenhouse gases (GHGs), global-mean surface
temperature (T) has shown no discernible warming since about 2000, in sharp contrast to …

Despite continued growth in atmospheric levels of greenhouse gases, global mean surface
and tropospheric temperatures have shown slower warming since 1998 than previously …

We use a newly developed technique that is based on the information flow concept to
investigate the causal structure between the global radiative forcing and the annual global …

Ozone changes and associated climate impacts in the Coupled Model Intercomparison
Project Phase 5 (CMIP5) simulations are analyzed over the historical (1960–2005) and …
