Earth’s polar regions — the Arctic and the Antarctic — are far from where most of us live. What’s happening there now as a result of climate change, however, will end up affecting us in very direct ways. Melting glaciers and ice caps are raising sea level worldwide, and new research released in 2012 shows that the melting, especially in Antarctica,… Read More
The gathering of United Nations advisers, climate experts, and international students was billed as a snapshot of the “State of the Planet. As such, it did not paint a very rosy picture.… Read More
Despite a series of low-pressure systems that brought rain to the northern Great Plains, the Midwest, the Mid-Atlantic states, and Florida over the past week or so, the drought that has gripped the Lower 48 states since the spring (and even longer than that, in some areas) is still holding on, according to the latest update of the U.S. Drought … Read More
Scientists expect sea level to go up by 3 feet or so by the end of this century, thanks mostly to changes in the great ice sheets that dominate Greenland and Antarctica — but they worry about unknown factors that might drive ice into the sea faster than projected. Now a pair of MIT scientists has identified what might, in theory, turn out to be one… Read More
The study, which relies on climate model simulations as well as weather data for the past 40 years, shows that the Bermuda High has already expanded westward, which could be making summertime rainfall in the Central and Southeast U.S. much more variable.… Read More
Scientists at Arizona State University have announced a new computer simulation that displays a city’s greenhouse-gas emissions in unprecedented detail, showing how much heat-trapping carbon dioxide individual buildings and highways generate. The model, known as Hestia (after the Greek goddess of the hearth), and described in a paper in the … Read More
NOAA’s latest State of the Climate roundup shows that September marked the 16th month in a row of above-average temperatures for the Lower 48 states of the U.S. Over the month, the mercury averaged 67°F, which is 1.4°F higher than the long-term average. The period April-September, which is considered the “warm season in the continental U.S., was … Read More
If uncertainty could be reduced to zero, though, climate negotiations would be transformed from a classic “prisoner’s dilemma, in which countries have a perverse incentive to do less than what is required in order to solve a shared problem, and into a coordination game, in which countries would work with one another to ensure they are making suffi… Read More
