Deep-sea Core From Okinawa Trough Gives 200,000-year Environmental History Of Continental Shelf
2013-09-26 09:38:37

Science China Press A new research paper shows that a great number of nearby terrigenous pollen and charcoal have been found from the deep-sea sediments of the last 200 kyrs in Okinawa Trough. It is tesitfied that the continental shelf of the East China Sea was exposed and covered with the huge wetland and grassland ecosystems during the the last two glacial periods. They discovered that the variation of terrestrial sources is concordent with global glacial volume and sea-level changes at...

Higher Latitude Moths Less Susceptible To Temperature Changes
2013-09-24 10:11:14

Dartmouth College Moths in northern Finland are less susceptible to rising temperatures than expected, suggesting high latitude moth populations around the world may be partly buffered from the effects of rapid climate warming, according to a new Dartmouth-Finnish study based on the most extensive analyses yet conducted of seasonal patterns in forest animals. The results are important because moths are a key food source for birds, bats and many other predators, and (in their caterpillar...

Global Warming To Shift Rain And Wind Belts: Experts
2013-09-24 04:32:23

April Flowers for redOrbit.com - Your Universe Online A new study from Columbia University's Lamont-Doherty Earth Observatory reveals that a northward shift of Earth's wind and rain belts could make a broad swath of regions drier. The findings, published in Proceedings of the National Academy of Sciences, show that these drier regions include the Middle East, American West and Amazonia, while Monsoon Asia and equatorial Africa will become wetter as humans continue to heat the planet....

While we grapple with the impact of climate change, archaeologists suggest we spare a thought for Aboriginal Australians who had to cope with the last ice age. "The period scientists call the Last Glacial Maximum, or LGM for short, is the most significant climatic event ever faced by humans on this continent," Associate Professor Sean Ulm from James Cook University in Cairns said. Research recently published in the Journal of Archaeological Science sheds new light on the ways Aboriginal...

Our current pledges to reduce greenhouse gas emissions, which are projected to set the global mean temperature increase at around 3.5°C above pre-industrial levels, will expose 668 million people worldwide to new or aggravated water scarcity. This is according to a new study published today, 13 September, in IOP Publishing's journal Environmental Research Letters, which has calculated that a further 11 per cent of the world's population, taken from the year 2000, will live in water-scarce...

Marine Animals Follow Cooler Waters To Escape Climate Change
2013-09-13 11:21:50

Brett Smith for redOrbit.com - Your Universe Online Like humans headed for air-conditioning during the hot summer months, mobile marine life will often move en masse to avoid rising temperatures. With climate change expected to drive ocean temperatures up a few degrees, a team of American and Canadian scientists decided to investigate how shifting temperatures might affect the large scale movements of marine life, in a new report published Friday in the journal Science. According to...

Understanding A Century Of Human Impact On Arctic Climate
2013-09-12 13:02:22

Desert Research Institute The Arctic is the most rapidly warming region of the globe, but warming has not been uniform and the drivers behind this warming not fully understood even during the 20th century. A new study authored by Canadian and American investigators and published in Scientific Reports, a primary research publication from the publishers of Nature, suggests that both anthropogenic and natural factors – specifically sulphate aerosols from industrial activity and volcanic...

Many climate studies have predicted that tree species will respond to global warming by migrating via seed dispersal to cooler climates. But a new study of 65 different species in 31 eastern states finds evidence of a different, unexpected response. Nearly 80 percent of the species aren’t yet shifting their geographic distributions to higher latitudes. Instead, they’re staying in place – but speeding up their life cycles. The Duke University-led study, published online Wednesday...

Europe's Hottest Days Becoming Hotter Because Of Climate Change
2013-09-12 06:19:13

redOrbit Staff & Wire Reports - Your Universe Online While climate change has caused temperatures to spike throughout much of the world, a stretch of Europe from southern England and northern France to Denmark has been especially affected, according to new research published Wednesday in the journal Environmental Research Letters. Researchers, from the Grantham Research Institute on Climate Change and the Environment at the London School of Economics and Political Science and the...

Rainfall In South Pacific Varied Much More Dramatically Before 20th Century
2013-09-10 09:16:25

The University of Texas at Austin A new reconstruction of climate in the South Pacific during the past 446 years shows rainfall varied much more dramatically before the start of the 20th century than after. The finding, based on an analysis of a cave formation called a stalagmite from the island nation of Vanuatu, could force climate modelers to adjust their models. The models are adjusted to match the current levels of climate variability that are smaller now than they were in the recent...

Climate Change
2013-04-01 11:05:27

Climate change is a substantial and lasting change in the statistical distribution of weather patterns over periods of time ranging from decades to millions of years. It might be a change in the average weather conditions, or in the distribution of weather around the average conditions. Climate change is a result of factors that include oceanic processes, biotic processes, variations in solar radiation received buy Earth, volcanic eruptions, and plate tectonics, and human induced alterations...

Current Sea Level Rise
2013-04-01 10:39:21

The sea levels all around the world are rising. Current sea-level rise has the potential to affect human populations and the natural environment. Two key factors have contributed to the observed sea level rise. The first is thermal expansion: as the ocean water warms, it expands. The second is from the influence of land-based ice because of increased melting. The major store of water on land is found in the glaciers and the ice sheets. The rising of sea levels is one of several lines of...
