Shifting Cities: How Hot Will Summers Be By 2100?

Monthly average maximum daily temperature (Tmax) was taken as the median of a suite of 31 global climate models from the Coupled Model Intercomparison Project 5 (CMIP5). Average summertime Tmax was calculated by averaging monthly Tmax for June, July, and August in the northern hemisphere, and December, January, and February in the southern hemisphere. This was done for two periods: 1996-2015 under RCP 8.5 (current), and 2080-2099 under RCP 4.5 and 8.5. To match origin cities to destination cities we found a list of all cities whose current summer Tmax was within 0.5°C of the origin’s projected summer Tmax, then chose the geographically closest destination city. This was repeated for RCP 4.5 and RCP 8.5. Source: climatecentral.org Related post: -  Find cities with similar climate

Air Quality in the Unites States

Climate change will increase the number of bad air days across much of the United States. This puts millions of Americans at risk for irritated eyes, noses, and lungs, but it’s particularly dangerous for young children, older adults, people who work or exercise outside, and our country’s more than 24 million asthma sufferers.

CO2 emissions per capita by country

CO2 emissions are the central driver of global climate change. It’s universally recognized that to evade the most severe consequences of climate change, the world must urgently reduce emissions.   In 1950 the world emitted six billion tonnes of carbon dioxide . By emission had roughly quadrupled, touching more than 22 billion tonnes. Later CO2e missions have proceeded to multiple, reaching more than 36 billion tonnes every year. In the twentieth century, global carbon dioxide emissions were dominated by Europe and the United States. In 1900, more than 90 percent of emissions were created in Europe or the United States. Even by 1950, they estimated for more than 85 percent of emissions each year! In the second half of the twentieth century, everything changed. Significant increases in carbon dioxide emissions have occurred in Asia, especially in China. Today, the United States and Europe estimate for just under 1/3 of emissions of CO2.
