• Global average temperature was 0.98°C (1.76 °F) higher in 2020 than in the late 1800s.15 • The warmest year on record since records began in 1880 was 2016, with 2020 ranking second. In 2020 global average land temperatures experienced a record high, while 2016 global ocean temperatures remain the highest on record.
Climate change is altering temperature, precipitation, sea levels, and will adversely impact human and natural systems, including water resources, human settlements and health, ecosystems, and biodiversity. 1 The unprecedented acceleration of climate change over the last 50 years and the increasing confidence in global climate models add to the ...

Geoengineering (PDF - 1.9MB) Daniel Cziczo. This section provides the schedule of lecture topics and instructors along with lecture notes for select sessions.
Scientists know that recent climate change is largely caused by human activities from an understanding of basic physics, comparing observations with models, and fingerprinting the detailed patterns of climate change caused by different human and natural influences.
temperature-albedo feedback. That is, warming of the atmosphere or ocean causes a decrease of sea ice extent, the exposure of more open water (as well as more melt ponds over sea ice), and increased absorption of solar radiation at the surface, leading to further warming.
current understanding of global warming and climate change, as well as societal implications and the political barriers to sound, rational policy. Its co-authors are well recognized experts in science and in public policy.
