It’s 2025. Where Do Most People Live?
Researchers at the Center for Climate Systems Research (CCSR), a part of The Earth Institute, have developed a high-resolution map of projected population change for the year 2025. The innovative map shows a world with large areas of population loss in parts of Eastern Europe and Asia, but significant gains elsewhere. The work, Mapping the…

New Study of Glacial Retreat Shows that Much of the World Emerged from Last Ice Age at Nearly the Same Time
The end of the recurring, 100,000-year glacial cycles is one of the most prominent and readily identifiable features in records of the Earth’s recent climate history. Yet one of the most puzzling questions in climate science has been why different parts of the world, most notably Greenland, appear to have warmed at different times and…

Researchers Assess Risks Associated with Living in Low-Lying Coastal Areas
For many, sea-level rise is a remote and distant threat faced by people like the residents of the Tuvalu Islands in the South Pacific, where the highest point of land is only 5 meters (15 feet) above sea level and tidal floods occasionally cover their crops in seawater. Now, however, a recently published study by…

Could Reducing Global Dimming Mean a Hotter, Dryer World?
Despite concerns over global warming, scientists have discovered something that may have actually limited the impact of greenhouse gases in the atmosphere in recent years by reducing the amount of sunlight reaching the surface of the Earth. In research they published last year in the journal Geophysical Research Letters, a team led by Beate Liepert…
