Predicted long-term drought in the Horn of Africa

Predicted long-term drought in the Horn of Africa

Posted Tue, 15 Feb 2011 07:33:00 GMT by Michael Evans

Scientists predict that a warming Indian Ocean will create drought conditions in Kenya and Ethiopia. Regular droughts have long been regarded as a feature of eastern Africa, but over the past 20 years the frequency of these droughts has noticeably increased. According to new research published in Climate Dynamics, this is likely to continue as global temperatures continue to rise.

New research in Australia gives real hope that plants can respond to climate change, by rapidly evolving. This is the first study, published in the Journal of Ecology that shows just how widespread this ability is in plants.

New farming methods to reduce greenhouse gases and improve yields

New farming methods to reduce greenhouse gases and improve yields

By drilling a field in foot wide strips, nine inches deep, and planting maize and adding nitrate fertiliser at the same time, this increases yields and reduces the amount of nitrate escaping into the atmosphere as nitrous oxide. Although carbon dioxide (CO2) is widely held to be the major contributor to global warming, scientists believe that the contribution of nitrous oxide (N2O) is about 300 times more than CO2.

Scientists believe that a shrinking Arctic ice cap is introducing warmer fresh water into the Atlantic to slow the warming effects of the Gulf Stream and cool down northwest Europe as a consequence. Britain has just suffered its coldest winter for 100 years, bringing freezing, snowy weather that paralysed the country. Scientists say that these icy winters could become a regular feature simply because the world is getting warmer.

Man has been influencing Earth's climate for at least 8,000 years say Swiss researchers. The rise and fall of the Roman Empire; the Black Death, and the colonisation of the Americas all had a significant impact on the environment due to changes in forestation. Early man began by clearing woody areas to improve hunting and gathering opportunities. Next the first farmers had a larger impact by clearing forest for early slash and burn agriculture.

Falling ice and snow cover hampering Arctic's reflective capabilities

The degree to which the Arctic region can reflect the sun's rays has declined significantly over the past three decades, a team of US researchers have warned. The ongoing loss of snow and ice in the Northern Hemisphere is not just depriving polar bears of their natural habitat, but it is leading to a reduction of the region's solar reflexivity and thereby exacerbating the problem of global warming.

By looking to the past, one team of US scientists believe they can map out the likely changes to the Earth's climate ongoing rises in carbon emissions will bring. one team of US researchers has been looking to the past in order to gain an understanding of the potential consequences of the major rise in the volume of carbon dioxide in the Earth's atmosphere seen since the dawn of the Industrial Revolution. Specifically, the experts at the National Center for Atmospheric Research in Boulder, Colorado, have been asking: When was the last time the Earth's atmosphere contained as much carbon dioxide as it may by the end of this century?

Smaller glaciers, not giant ice caps, tipped to push sea levels up

Melting mountain glaciers rather than the ice sheets of the Antarctic will be the biggest contributor to rising sea levels over the decades ahead, scientists believe. That climate scientists looking into rising sea levels are currently directing their research at the massive ice caps of the Arctic and the Antarctic is hardly surprising.

Scrap the beef, pork, and chicken from your diet if you want to improve your carbon footprint. Edible insects like mealworms, locusts and crickets produce a fraction of the greenhouse gases per kilo of protein than more conventional meals.

Growth rings in fossil and living deep sea corals tell scientists about Atlantic Ocean currents and may provide clues to links between these and global warming. Like tree rings and ice cores, the annual growth rings in deep sea gorgonian corals can tell us about the past environment, and are a new and dependable source of data about the deep ocean. Dr Owen Sherwood, a biogeochemist and lead author of a new study spoke to Earth Times today

Drilling for half a million years of history under the Dead Sea

A project to drill under the Dead Sea that will hopefully reveal half a million years of the areas's geological and climatic history. There is little doubt in scientific minds that the world is getting warmer. This is particularly evident in the Middle East, but one important question is whether this is something new or whether it is part of some larger cyclical pattern.

The effects of a colder Bering Sea on the feeding habits of pollock

A three-year dip in Bering Sea temperature has caused a change in the distribution of the staple food of pollock. The Bering Sea is considered to be one of the world's most productive fisheries and its northern portions are the home of sea ducks, grey whales, bearded seals and walruses, but a 30-year warming trend has been bad news for those animals that are adapted to a cold-water environment, causing them to migrate further north.

Burps, not farts, cause for methane production among cattle. Every cow, on average, produces 80kg to 100kg (CH4) of methane per year, a gas that has the nasty habit of depleting the ozone layer. The reason for this is enteric - in other words, it's related to digestion, but not in the way you might imagine.

In Africa, the effects of climate change are already being felt, primarily in the form of reduced rainfall and desertification. These effects could substantially alter farming, leading to food shortages. To mitigate such impacts of global warming, information and communication technologies (ICTs) may have an important role to play.

Short-term weather extremes cause melting of Greenland Ice Sheet

Short-term weather extremes cause melting of Greenland Ice Sheet

New research indicates that short-term weather extremes and not global warming are the cause of Greenland ice sheet melt. Roughly 80 per cent of Greenland's land surface is hidden under an ice sheet consisting of layers of compressed snow. It is accepted that approximately 100 billion tonnes of this ice are lost each year as the sheet progressively shrinks.

Although some progress was made this year at the United Nations Framework Convention on Climate Change, there is still much more to be done in the fight to protect the environment. The event was held in Cancun, Mexico, and although there were no giant leaps made, the members left feeling more confident that they can work together in the future and eventually come to a binding global agreement on climate change.
