WASHINGTON—Rocket exhaust could become a significant contributor to global climate change in coming decades, according to a new study. The research finds that soot emitted by rockets — not their carbon dioxide emissions — has the greater potential to contribute to global climate change in coming decades. (more…)

As Earth’s climate warms, species are expected to shift their geographical ranges away from the equator or to higher elevations.
While scientists have documented such shifts for many plants and animals, the ranges of others seem stable. (more…)
ARMONK, N.Y. – 22 Oct 2010: IBM (NYSE: IBM) inventors have developed a patented natural disaster warning system, which uses analytics to improve the effectiveness and timeliness of post-event rescue efforts in cities and other locations where efficient emergency response is essential following a natural disaster. It also offers a means to accurately predict the location and timing of subsequent catastrophic events, which will further aid evacuation efforts. (more…)

Sixty-three percent of Americans believe that global warming is happening, but many do not understand why, according to a national study conducted by researchers at Yale University.
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 Smithsonian Tropical Research Institute’s Bocas del Toro Research Station and Galeta Point Marine Laboratory are reporting an anomalous sea temperature rise and a major coral bleaching event in the western Caribbean. Although the U.S. National Oceanic and Atmospheric Administration, NOAA, issued an advisory in July announcing above-average sea surface temperatures in the wider Caribbean region, there had been no clear indication of increased sea temperatures in Panama and the western Caribbean until late August-early September.
