April Flowers for redOrbit.com - Your Universe Online The world's largest tropical desert, the Sahara, has suffered a catastrophic collapse of its wildlife populations, according to a new study led by the Wildlife Conservation Society (WCS) and Zoological Society of London (ZSL). The research team consisted of 40 scientists from 28 international organizations. They assessed 14 desert species, finding that half of those are regionally extinct or confined to one percent or less of their...

University of Arizona Comparing plant communities today with a survey taken 50 years ago, a UA-led research team is providing the first on-the-ground evidence for Southwestern plants being pushed to higher elevations by an increasingly warmer and drier climate. In a rare opportunity to directly compare today's plant communities with a survey taken in the same area 50 years ago, a University of Arizona-led research team has provided the first on-the-ground evidence that Southwestern...

This Envisat image shows part of central Morocco from the Atlantic Ocean to the west, over the Atlas mountains and into arid parts of Algeria further inland. The snow-capped High Atlas mountain range divides Morocco from the Sahara desert´s climatic influences in Algeria. Northwest of the mountains, the area experiences a more Mediterranean-like climate, with dry and hot summers and moderate winters with a fair amount of rain. Several peaks in the mountain range exceed 4000 m and...

  [ View the Video ] A NASA-led team has used radar sounding technology developed to explore the subsurface of Mars to create high-resolution maps of freshwater aquifers buried deep beneath an Earth desert, in the first use of airborne sounding radar for aquifer mapping. The research may help scientists better locate and map Earth's desert aquifers, understand current and past hydrological conditions in Earth's deserts and assess how climate change is impacting them. Deserts...

Australians can learn much from their deserts and from desert people about how to cope with climate change and scarce resources. That's one of the messages of a new book launched in the Federal Parliament by Senator Trish Crossin today for the Desert Knowledge CRC and CSIRO Publishing. "Dry Times: Blueprint for a Red Land" argues that desert plants, animals and people have been surviving and thriving for thousands of years on scarce resources and uncertain climates "“ and they have the...

Global warming is giving a boost to Sonoran Desert plants that have an edge during cold weather, according to new research. Although the overall numbers of winter annuals have declined since 1982, species that germinate and grow better at low temperatures are becoming more common. "It's an unexpected result -- that global warming has led to an increase in cold-adapted species," said lead author Sarah Kimball, a research associate at the University of Arizona in Tucson. "Because the winter...

On Thursday, one of the world's wealthiest men, Mexican billionaire Carlos Slim, launched a joint $100 million project with the Mexican government and the World Wildlife Fund to protect Mexico's environment. "I believe that looking after the environment will be one of the big generators of jobs in the future," Slim told the AFP while on a beach on Mexico's Caribbean island of Cozumel. "Whether there's a crisis or not, the cost of looking after the environment and reducing risks is more...

Reconstructing the climate of the past is an important tool for scientists to better understand and predict future climate changes that are the result of the present-day global warming. Although there is still little known about the Earth's tropical and subtropical regions, these regions are thought to play an important role in both the evolution of prehistoric man and global climate changes. New North African climate reconstructions reveal three "Ëœgreen Sahara' episodes during...
