Climatic changes increase malicious parasites potency

Mon, 13/08/2012 - 13:39 by Minnie Mahendru

Climatic changes predict the parasites to become more active and potent attacking the host in a big way. A study highlighted that the frogs when facing unforeseen and surprising changes in the general temperatures experience a larger number of diseases.

Kids' fevers may not always require medicines--pediatricians

Relying too much on medicines like paracetemol and ibuprofen to treat your child's fever? If so, hold on, as a new report from the American Academy of Pediatrics (AAP) suggests that not all fevers require treatment.

Moon of Saturn may have hidden ocean

Fri, 08/10/2010 - 11:15 by Prince damin

Greenbelt, Md. -- A moon of Saturn that should be frozen solid may have liquid oceans, thanks to a "wobble" it experiences as it orbits the ringed planet, researchers say.

With temperatures around 324 degrees below zero Fahrenheit, the surface of Enceladus is indeed frozen, but in 2005 NASA's Cassini spacecraft discovered a giant plume of water gushing from cracks in the surface over the moon's south pole, suggesting there was a reservoir of water beneath the ice, a release from NASA's Goddard Space Center said Thursday.

Analysis of the plume by Cassini shows the water is salty, indicating the reservoir is large, perhaps even a global subsurface ocean.

Huge coral die-off reported in Indonesia

Tue, 17/08/2010 - 09:35 by Prince damin

Jakarta -- A conservation group says a massive "bleaching" die-off of coral in Indonesia has been caused by a rise in surface sea temperatures.

"Bleaching"-- a whitening of corals that occurs when algae living within coral tissues are expelled -- is an indication of stress caused by environmental triggers such as sea surface temperature fluctuations, a Wildlife Conservation Society release said Monday. Marine biologists investigating coral bleaching in May off the northern tip of Sumatra found more than 60 percent of the corals in the area were bleached.

Depending on many factors, bleached coral may recover over time or it can die, the release said.

Warming could affect ocean food chain

Sat, 31/07/2010 - 01:57 by Prince damin

Halifax, Nova Scotia -- Scientists say the amount of ocean plankton, the foundation of the aquatic food chain, has declined over the past century as ocean temperatures have risen.

Researchers say the first comprehensive global look at plankton changes over a long time scale shows Phytoplankton, tiny marine plants, declining in the upper layers of ocean water by about 1 percent a year, the BBC reported Friday.

"What we think is happening is that the oceans are becoming more stratified as the water warms," said research leader Daniel Boyce from Dalhousie University in Halifax, Nova Scotia.

"The plants need sunlight from above and nutrients from below; and as it becomes more stratified, that limits the availability of nutrients," he said.

Great Lakes at near-record temperatures

Detroit -- North America's Great Lakes are warmer than usual -- as much as 15 degrees above normal -- and could get record temperatures this summer, experts say.

Each of the Great Lakes is showing temperatures well above normal for this time of year, the result of a shortened winter season and a hot spring, The Detroit News reported Friday.

"All of the lakes are either at or approaching their normal temperatures for late August," Jay Austin, a physics professor at the University of Minnesota, said. "They're already at what we would have expected to be their peak temperatures for the summer, and we have several more weeks of warming to go."

2010: Warmest year on record?

Sat, 17/07/2010 - 02:09 by Pankaj Damin

Washington -- Record-setting temperatures in March, April and June made 2010 the warmest year worldwide since the start of record keeping in 1880, climate experts say.

National Oceanic and Atmospheric Administration data showed the average temperature in June to be 1.22 degrees higher than the historical average, USA Today reported Friday.

"It's part of an overall trend," Jay Lawrimore, climate analysis chief at NOAA's National Climatic Data Center, said. "Global temperatures ... have been rising for the last 100-plus years. Much of the increase is due to increases in greenhouse gases."

If the trend continues, Lawrimore said, flooding rains will become more common.

Stream and river temperatures increasing

Fri, 09/04/2010 - 12:19 by Pankaj Damin

College Park, Md. -- A study suggests water temperatures are increasing in many U.S. rivers and streams, including the Colorado, Potomac, Delaware and Hudson rivers.

The study -- led by a team of University of Maryland ecologists and hydrologists -- documents 20 major U.S. streams and rivers show statistically significant long-term warming that was typically correlated with increases in air temperatures. The researchers said rates of warming were most rapid in urbanized areas.

Past decade warmest since 1880: NASA

New York, January 22 -- Space agency NASA has released the results of a new study on climate change. According to its estimates, temperatures in the decade ended 2009 were warmest since 1880.
