Taking Measure of the Greenhouse Effect

WASHINGTON — Scientists have long known that heat-absorbing components of Earth’s atmosphere, such as clouds and certain gases, prevent our planet from being an ice-covered ball. Now a study, for the first time, comprehensively calculates the relative contributions of the components responsible for that heating, known as the greenhouse effect.

Besides clarifying an important aspect of climate science, the study also demonstrates that rising concentrations of one heat-trapping gas — carbon dioxide — leads to much more greenhouse warming than just the heat the gas absorbs directly itself.

Various studies have looked at the contributions of water vapor, CO₂, and other greenhouse gases. But none had systematically estimated the contributions of each of the main players, says climate scientist Gavin Schmidt of NASA Goddard Institute for Space Studies, and lead author of the new research.

The Arctic sea ice cover appears to have reached its minimum extent for the year, the third-lowest recorded since satellites began measuring sea ice extent in 1979, according to the University of Colorado at Boulder’s National Snow and Ice Data Center.

Who Gains Profit from Global Warming Myth?

The unusually hot summer that devastated Russia this year once again reminded of a trendy horror story called “global warming.” Proponents of this hypothesis, talking about their cause, have entirely lost sight of an abnormally cold winter in the Southern Hemisphere. Their opponents said that single point cannot be used for plotting. However, reasonable arguments both for and against the warming have not been presented to the general public.

There is an old joke about a weather station in Chukotka.

Global Warming Could Spell Disaster for Corn Crops

If corn producers continue using the same cultivars, plants selected for their desirable characteristics, global warming could cause production to drop from 1.3 to 10 percent between 2010 and 2039.

*Greenhouse gases are playing a role in changes, say scientists*

Newly detected rising sea levels in parts of the Indian Ocean, including the coastlines of the Bay of Bengal, the Arabian Sea, Sri Lanka, Sumatra and Java, appear to be at least partly a result of human-induced increases of atmospheric greenhouse gases, says a study led by the University of Colorado at Boulder.

The Chaiten Volcano after 9,000 years

By ShamsMay 7, 2008EnvironmentChaiten volcano, Chile, greenhouse gases, NASA, radiocarbon dating

The Chaiten volcano in southern Chile sprung to life for the first time in thousands of years. The powerful eruption sent ash more than 20 km into the sky and caused a poor visibility in the area. After drifting across Argentina (the southern most country), the plume of ash dissipated over the Atlantic.
