Deep Oceans May Mask Global Warming for Years at a Time

*Computer simulations of global climate lead to new conclusions*

Earth’s deep oceans may absorb enough heat at times to flatten the rate of global warming for periods of as long as a decade–even in the midst of longer-term warming. This according to a new analysis led by scientists at the National Center for Atmospheric Research (NCAR).

The study, based on computer simulations of global climate, points to ocean layers deeper than 1,000 feet as the main location of the “missing heat” during periods such as the past decade when global air temperatures showed little trend. (more…)

Arctic Ice Melt Could Pause in Coming Decades

*Researchers find unexpected results in study of ice cover in the Arctic*

Despite the rapid retreat of Arctic sea ice in recent years, the ice may temporarily stabilize or somewhat expand at times over the next few decades, new research indicates.

Results of a study by scientists at the National Center for Atmospheric Research (NCAR) appear this week in the journal Geophysical Research Letters (GRL), published by the American Geophysical Union.

The National Science Foundation (NSF), NCAR’s sponsor, funded the work. (more…)

Economic Cost of Weather May Total $485 Billion in U.S.

*Routine weather events can add up to huge annual economic impact*

Everything has its price, even the weather.

New research indicates that routine weather events such as rain and cooler-than-average days can add up to an annual economic impact of as much as $485 billon in the United States.

The study, led by scientists at the National Center for Atmospheric Research (NCAR), found that finance, manufacturing, agriculture and every other sector of the economy is sensitive to changes in the weather. The impacts can be felt in every state. (more…)

Air Quality Worsened by Paved Surfaces

*Widespread urban development alters weather patterns*

New research focusing on the Houston area suggests that widespread urban development alters weather patterns in a way that can make it easier for pollutants to accumulate during warm summer weather instead of being blown out to sea.

The international study, led by the National Center for Atmospheric Research (NCAR), could have implications for the air quality of fast-growing coastal cities in the United States and other mid-latitude regions overseas. (more…)

The United States and many other heavily populated countries face a growing threat of severe and prolonged drought in coming decades, according to results of a new study by National Center for Atmospheric Research (NCAR) scientist Aiguo Dai. (more…)
