The American Power Act (APA) proposes a comprehensive US framework to reduce greenhouse gas emissions through a mandatory cap-and-trade system, targeted emission reduction goals, and strategic investments in clean energy. The bill establishes a phased-in cap on covered gases, starting in 2013 and reaching an 83 percent reduction below 2005 levels by 2050. It includes specific provisions to expedite nuclear power development, deploy carbon capture and sequestration (CCS), and provide financial assistance to consumers and workers during the transition to a low-carbon economy. The APA also addresses international climate activities, including the use of international offsets and border adjustments to prevent carbon leakage.

The study concludes that human-induced climate change significantly increased the probability of the 2022 summer soil moisture droughts in both West-Central Europe and the Northern Hemisphere extratropics, primarily driven by a strong increase in high temperatures rather than precipitation deficits. For West-Central Europe, the likelihood of root-zone soil moisture drought increased by 3-4 times and surface soil moisture drought by 5-6 times. In the Northern Hemisphere extratropics, the increase was more pronounced, with the likelihood of root-zone drought increasing by at least 20 times and surface drought by at least 5 times. These conditions led to severe impacts on agriculture, energy production, and water infrastructure, compounded by socio-economic stressors such as the conflict in Ukraine.
