Baja watching Tropical Storm Patricia in the latest GOES-11 satellite movie
The nineteenth tropical cyclone of the Eastern Pacific formed over this past weekend, and strengthened into Tropical Storm Patricia. view more (2009-10-14)
Tropical forest seed banks: a blast from the past
Seeds of some tree species in the Panamanian tropical forest can survive for more than 30 years before germinating. view more (2009-04-02)
Forests - just how absorbing are they?
Forests form an integral part of the Kyoto Protocol on climate change because they act as terrestrial "sinks" to soak up the carbon emissions that are contributing to global warming. Countries that have ratified the protocol can offset their carbon emissions quota by planting trees, either at home or in developing countries. But how... view more... (2003-03-13)
Cyclones spurt water into the stratosphere, feeding global warming
Scientists at Harvard University have found that tropical cyclones readily inject ice far into the stratosphere, possibly feeding global warming. view more (2009-04-21)
NASA eyes Hilda's Hawaiian hangout -- south of the islands
Tropical Storm Hilda is hanging on to tropical storm force winds, and continues to track south of the Hawaiian Islands. NASA's Tropical Rainfall Measuring Mission satellite noticed some moderate rainfall in Hilda's center earlier today, but the storm is staying far enough south of Hawaii to not cause trouble for travelers and vacationers. view more (2009-08-27)
Forests Could Benefit When Fall Color Comes Late
Do those fall colors seem to show up later and later-if at all? Scientists say we can blame increasing amounts of carbon dioxide in the atmosphere for prolonging the growing season of the trees. And that may actually be good news for forestry industries. view more (2008-01-23)
Accuracy of past hurricane counts good
Counting tropical storms that occurred before the advent of aircraft and satellites relies on ships logs and hurricane landfalls, making many believe that the numbers of historic tropical storms in the Atlantic are seriously undercounted. view more (2007-11-26)
Global warming dramatically changed ancient forests
The migration of subtropical plants to northern climates may not be too far-fetched if future global warming patterns mirror a monumental shift that took place in the past. view more (2005-11-14)
Nitrogen retained through loss
The nitrogen cycle plays a major role in seagrass fields. Dutch researcher Arie Vonk studied the nitrogen dynamics of seagrasses in Indonesia. He discovered that the interaction between seagrasses, animals and microorganisms results in an efficient nitrogen cycle in tropical seagrass fields. Consequently the nitrogen lost from seagrasses is still... view more... (2008-05-23)
Neglected tropical diseases burden those overseas, but travelers also at risk
Though little known to most Americans, lymphatic filariasis, trachoma, leishmaniasis, onchocerciasis, schistosomiasis and other so-called neglected tropical diseases are responsible for severe health burdens, especially among the world's poorest people. view more (2007-12-26)
Ignacio May Get Some Company in the Eastern Pacific
Tropical Storm Ignacio may not be alone in the Eastern Pacific Ocean for long. There are two areas of showers and thunderstorms that forecasters are watching for development, farther east and closer to land. view more (2009-08-27)
A bee's future as queen or worker may rest with parasitic fly
Strange things are happening in the lowland tropical forests of Panama and Costa Rica. A tiny parasitic fly is affecting the social behavior of a nocturnal bee, helping to determine which individuals become queens and which become workers. view more (2008-07-29)
Diversity of trees in Ecuador's Amazon rainforest defies simple explanation
Trees in a hyper-diverse tropical rainforest interact with each other and their environment to create and maintain diversity, researchers report in the Oct. 24 issue of the journal Science. view more (2008-10-24)
Passenger Screening Advised To Cut Risk Of Importing Drug-Resistant Malaria To Africa
Imported resistance has rendered ineffective the two affordable malaria drugs which have been the mainstay of malaria treatment in Africa for forty years, according to experts writing today in the journal Science. Scientists from the London School of Hygiene and Tropical Medicine and colleagues from institutions in the USA, South Africa and... view more... (2004-08-16)
NASA satellite reveals a depressed and disorganized Henri
Depression happens to everyone, even tropical storms, and Henri is now tropically depressed. NASA satellite imagery has confirmed he's weakened to a tropical depression and he is further expected to degenerate into a remnant low pressure area. view more (2009-10-09)
Genetic study shows humans have pushed orangutans to the brink of extinction
A new study published in the open-access journal PLoS Biology shows strong genetic evidence of a catastrophic collapse in orangutan populations living in the fragmented forests of the Kinabatangan Wildlife Sanctuary in Sabah, Malaysia. view more (2006-01-24)
For hurricanes, storms, raindrop size makes all the difference
When Tropical Storm Gaston hit Richmond, Va., in August 2004, its notable abundance of small and mid-sized raindrops created torrential rains that led to unexpected flash flooding throughout the city and its suburbs. New research from NASA has concluded that tropical cyclones like Gaston produce rain differently than another class of storms called... view more... (2008-06-10)
Fred Fades with a Satellite Exclamation Point
NASA's Aqua satellite flew over the remnants of Fred, September 13 and captured a visible image of the storm's clouds from the Atmospheric Infrared Sounder (AIRS) instrument. The AIRS image showed Fred's clouds stretched from northeast to southwest. view more (2009-09-15)
NASA diagnoses Tropical Storm Gert's growth spurt
Scientists want to know how a tropical cyclone develops from a weak tropical depression into a tropical storm. To answer that question, NASA and other scientists flew over and through storms in 2005 and obtained and combined data that let them see the storm in four dimensions. view more (2006-12-12)
NASA sees high thunderstorms in newly formed Tropical Cyclone 4A near India
Tropical Cyclone 4A formed yesterday, November 10 off the western coast of India in the Arabian Sea, and NASA's infrared imagery captured some high, powerful thunderstorms developing in the storm's center. view more (2009-11-11)
