Oxfam: Climate crises to affect 375 million by 2015

global warmingBangkok - Natural disasters caused by climate change are expected to affect 375 million people by the year 2015, threatening to overwhelm the current humanitarian aid system, a confederation of internatonal aid groups warned Tuesday.

Oxfam International Tuesday launched its report entitled The Right to Survive, studying the potential impact of climate change on the current humanitarian aid system.

Climate change aims need to be better integrated

Climate change aims need to be better integratedWashington, March 27 : A report published by the Partnership for European Environmental Research (PEER), has suggested that specific measures to tackle climate change, such as emissions trading, will only be successful if they are coherently supported by other government policies addressing economic and social issues.

The report explains that, in order to create an effective, Europe wide climate policy, climate change issues must be better integrated into both general and sector-specific policies such as taxation, transportation, and land use planning.

Animals may shrink in size because of global warming

Global WarmingLondon, Jan 5 : Ecologists have suggested that as a result of global warming, species will shrink in size, as bigger creatures will have more problems losing heat.

Though the effects of the climate change are likely not to be seen for many more years, it is important to consider how to preserve larger species right now.

"Our collective actions are negatively affecting body sizes of many living species," Kaustuv Roy, a biologist at the University of California in San Diego, told New Scientist.

Global warming can lead to spread of tick-borne disease

Global WarmingWashington, Dec 31 : Global warming might lead to the spread of tick borne diseases in humans, warns a professor at the University of Marseille School of Medicine in France.

Didier Raoult, a professor at the University of Marseille School of Medicine in France suggests that as global climate warms, dog ticks might be more likely to bite people, and tick-transmitted diseases might become more common.

In the spring of 2007, three men in France became seriously ill after sustaining bites from disease-infected dog ticks. The bites occurred after the hottest April since 1950.

Global warming might lead to birth of too many male fish

Washington, Dec 26 : A new study has determined that global warming might be leading to the birth of too many male fish.

According to a report in Live Science, some experts believe that the gender of many fish is determined by temperature, because temperature-dependent sex determination, or TSD, occurs in many species.

But, a critical analysis of the fish literature by Natalia Ospina-Alvarez and Francesc Piferrer, both of the Marine Science Institute in Barcelona, Spain, casts doubt on that assertion.

The pair point out that fourteen of the twenty diverse fish genera previously reported as having TSD in fact have sex chromosomes, and that it takes unnatural temperatures found only in the laboratory to masculinize their genetic females.

Global warming may hasten carbon release from world’s peat bogs

Global warmingWashington, Nov 7: A new analysis has determined that billions of tons of carbon sequestered in the world’s peat bogs could be released into the atmosphere in the coming decades as a result of global warming.

The analysis of the interplay between peat bogs, water tables, and climate change, was done by scientists at Harvard University, Worcester State College, and the Japan Agency for Marine-Earth Science and Technology.

Typically found at northerly latitudes, peat bogs are swampy areas whose cold, wet environment preserves organic matter, preventing it from decaying.
