When the climate warmed relatively quickly about 14,700 years ago, seasonal monsoons moved southward, dropping more rain on the Earth's oceans at the expense of tropical areas, according to climate researchers. If the same pattern occurs in the coming decades as the Earth's temperatures rises due to climate change, the highly-populated regions of the world that depend on monsoons could face more wildfires, water shortages and lower agricultural production.In an article to be published in the...

 At times in the distant past, an abrupt change in climate has been associated with a shift of seasonal monsoons to the south, a new study concludes, causing more rain to fall over the oceans than in the Earth's tropical regions, and leading to a dramatic drop in global vegetation growth.If similar changes were to happen to the Earth's climate today as a result of global warming "“ as scientists believe is possible - this might lead to drier tropics, more wildfires and declines in...

Dust trapped deep in Antarctic ice sheets is helping scientists unravel details of past climate change. Researchers have found that dust blown south to Antarctica from the windy plains of Patagonia "“ and deposited in the ice periodically over 80,000 years "“ provides vital information about glacier activity. Scientists hope the findings will help them to better understand how the global climate has changed during the past ice age, and so help predict environmental changes in the...

The Antarctic Peninsula juts into the Southern Ocean, reaching farther north than any other part of the continent. The southernmost reach of global warming was believed to be limited to this narrow strip of land, while the rest of the continent was presumed to be cooling or stable. Not so, according to a new analysis involving NASA data. In fact, the study has confirmed a trend suspected by some climate scientists. "Everyone knows it has been warming on the Antarctic Peninsula, where there...

Scientists are now making an alarming claim that the earth is on the brink of entering another Ice Age that could last the next 100,000 years. They believe a 12,000-year warming period is currently winding down. They say ice cores, ocean sediment cores, the geologic record, and studies of ancient plant and animal populations all demonstrate a regular cyclic pattern of Ice Age patterns, separated by intervening warm interglacials, each lasting about 12,000 years. Experts point out that most...

New research indicates that the ocean could rise in the next 100 years to a meter higher than the current sea level "“ which is three times higher than predictions from the UN's Intergovernmental Panel on Climate Change, IPCC. The groundbreaking new results from an international collaboration between researchers from the Niels Bohr Institute at the University of Copenhagen, England and Finland are published in the scientific journal Climate Dynamics.According to the UN's...

But global warming may have helped override some recent eruptions Climate researchers have shown that big volcanic eruptions over the past 450 years have temporarily cooled weather in the tropics "” but suggest that such effects may have been masked in the 20th century by rising global temperatures. Their paper, which shows that higher latitudes can be even more sensitive to volcanism, appears in the current issue of Nature Geoscience. Scientists already agree that large eruptions have...

Cooperative agreements signed with teams from the University of Wisconsin, Dartmouth College, University of New Hampshire are vital to climate studies The National Science Foundation (NSF)'s Office of Polar Programs (OPP) announced today the signing of cooperative agreements, one with a university collaboration comprising Dartmouth College, the University of New Hampshire, and the University of Wisconsin-Madison, and the other with the University of Wisconsin-Madison alone, that together...

The common wisdom is that the invention of the steam engine and the advent of the coal-fueled industrial age marked the beginning of human influence on global climate. But gathering physical evidence, backed by powerful simulations on the world's most advanced computer climate models, is reshaping that view and lending strong support to the radical idea that human-induced climate change began not 200 years ago, but thousands of years ago with the onset of large-scale agriculture in Asia and...

When Ohio State glaciologists failed to find the expected radioactive signals in the latest core they drilled from a Himalayan ice field, they knew it meant trouble for their research. But those missing markers of radiation, remnants from atomic bomb tests a half-century ago, foretell much greater threat to the half-billion or more people living downstream of that vast mountain range. It may mean that future water supplies could fall far short of what's needed to keep that population alive....
