Over a course of 12 days Dr. Giuliana Panieri and her colleagues from Centre for Arctic Gas Hydrate, Environment and Climate (CAGE) collected images from seven areas of known methane release in the Arctic Ocean. One of them was Vestnesa Ridge, with over 1000 active seep sites at the depth of over 1000 m.
The threat to human health from climate change is so great that it could undermine the last fifty years of gains in development and global health, according to a major new Commission, published in The Lancet.
Originally it became famous as an anesthetic gas used by dentists. However, laughing gas, or chemically correct nitrous oxide, is also found in large quantities in nature and has serious effects on climate: In the lower atmosphere it is a strong greenhouse gas, and in higher layers of the atmosphere it contributes indirectly to the destruction of ozone.
Global warming leads to the ice sheets on land melting and flowing into the sea, which consequently rises. New calculations by researchers from the Niels Bohr Institute show that the sea level in Northern Europe may rise more than previously thought. There is a significant risk that the seas around Scandinavia, England, the Netherlands and northern Germany will rise by up to about 1½ meters in this century. The results are published in a special issue of the scientific journal Climate Research.
In a study that contradicts the received wisdom on health impacts of climate change, scientists say that we shouldn't expect substantial reduction in winter deaths as a result of global warming. This new research is published today (Friday 19 June) in IOP Publishing's Environmental Research Letters journal.
Over billions of years, the total carbon content of the outer part of the Earth — in its upper mantle, crust, oceans, and atmospheres — has gradually increased, scientists reported this month in the journal Proceedings of the National Academy of Sciences.
Geologists and archaeologists from the Max Planck Institute for Evolutionary Anthropology (Germany), La Trobe University (Australia) and the University of Wollongong (Australia) identify previously unrecognised evidence for a "mega-lake" in the Australian desert 24,000 years ago, at the site of Lake Mungo in south-eastern Australia.
A team of researchers from the National Centers for Environmental Information (NCEI) of National Oceanic and Atmospheric Administration (NOAA) and LMI has performed a study which revealed that the speed of global warming over the last 15 years of this century has been as fast or faster when compared to the rate seen over the last half of the 20th century. The study, which has been published online in the journal Science, contradicts the idea that there has been a hiatus or slowdown in the rate of global warming over the past few years. The researchers used the new global surface temperature data to arrive at this conclusion.
A research team from Oregon State University has discovered that reservoirs on the Klamath River contain harmful algal blooms that are capable of travelling over 180 miles along the lower parts of the river in just a matter of days. These blooms are unaffected while travelling via hydroelectric turbines and ultimately lead to unsafe water conditions downriver in northern California.
For decades, scientists have relied on an established formula to measure the impact of greenhouse gas emissions on climate change.
