Beating Global Heat, But Only By Dumb Luck
After sweltering in New York City’s record temperatures the last couple of months, I recently traveled to the Peruvian Amazon. Oy, I thought. But instead of entering the mother of all sweat lodges, I found relief; for the most part, it was cooler in those tropical lowlands near the equator than outside my office at the corner of Broadway and 114th Street.…

Does temperature control atmospheric carbon dioxide concentrations?
A record of temperature and atmospheric CO2 from Antarctic ice cores shows the tight relationship between the two over the past 800,000 years (see figure). It is frequently asserted that changes in Earth’s temperature or, more specifically, the temperature of the ocean, caused atmospheric CO2 concentrations to vary over that time period. The underlying principle…

Dust and its Impact on Earth’s Climate System
Last month, Columbia’s Lamont-Doherty Earth Observatory hosted a conference on dust in the climate system as part of the NOAA funded Abrupt Climate Change in a Warming World (ACCWW) project. Most often, we think of dust simply as the stuff that accumulates on our windowsills, but those fine particles floating in the air play an…

An Active Hurricane Season Predicted
The IRI’s latest forecast for the Atlantic hurricane season, which started June 1, points to significantly increased hurricane activity this year. In fact, the likelihood of having an above-normal year is more than three times that of having a below-normal year. This could spell trouble for highly vulnerable Caribbean nations such as Haiti – still…
