COP26: U.N. climate summit in Glasgow

…science has gotten yet stronger about the difference between one-and-a-half and two degrees since 2015, and because many countries, including the United States, have suffered from climate damages that are attributable—that is you can nail it as being the result of climate change—there was a high expectation that countries would come in with some revolutionary…

Dr. Miyuki Hino: After climate-linked disasters, rebuild or move on?

…a lot of discussion recently about how climate change is going to affect where people live and certainly a lot of research indicating that climate risk is going to increase in some places. And that might lead to a lot of people deciding that where they live now is too hazardous or too dangerous to…

…are occurring five times more often than would be expected without global warming, suggesting that 80 percent of such monthly heat records are due to human-caused climate change.4Coumou, D. et al. (2013), Climatic Change, 118(3-4). 771. View Source With continued climate change, the frequency of these intense events is likely to increase5Mann, M.E., et al.,…

The climate-energy nexus

Key Concepts CO2 emissions from human activity are by far the primary cause of climate change, and about 93% of these CO2 emissions are caused by burning fossil fuels. That points to three powerful means of mitigating the negative effects of climate change: (1) transition to lower- or non-carbon energy sources such as hydropower, wind,…

Urban Heat: How rising temperatures affect U.S. cities

…wanted to point out is that climate change has already made it worse. So I’m sure you’ve heard reports about the recent devastating heat wave in the Pacific Northwest and that would have been virtually impossible without climate change. But beyond that, a study published earlier this year looking at data from over 40 countries…

Methane emissions in the United States

…However, there’s about 200 times less of it in the atmosphere because emissions are smaller, and it’s removed by chemistry. Chemistry in climate models used for the recent Intergovernmental Panel on Climate Change report, or the IPCC report, provide estimates of how different gases have contributed to changes in observed global temperature. According to climate…
