Natural Hazard Early Warning Systems Improved Using GPS Data

Posted by Mila Luleva in Climate Change on May 21, 2013

Scientists claim that the Global Positioning System (GPS) could save millions of lives by providing detailed information about upcoming natural hazards before they have occurred. As the effects of climate change are continuously accelerating, ice sheets are melting, sea level is rising and atmospheric currents are changing, we keep hearing about more and more cases [...]

The Earth Gets A Reprieve From Global Warming, For Now

Posted by Leigh Kim in Climate Change on May 20, 2013

Climatologists are breathing a collective sigh of relief. New data suggests that over the coming decade, the Earth will warm more slowly than previously thought. However, scientists stress that this is not a long-term reprieve – and temperatures are currently rising faster than they have been for the past 11, 000 years. The Earth warmed [...]

Scientists Optimistic About Temperature Rise Rates

Posted by Mila Luleva in Climate Change on May 20, 2013

Lower rates of global warming over the past few years do not indicate slower increase in temperatures in a long-term, according to a recent study in Nature Geoscience. An international team of scientists conducted a detailed study, which indicates that the lower rates are associated with the absorption of heat by the Earth’s oceans. Using [...]

Climate Change is Man-Made, Scientists Unanimously Agree

Posted by Mila Luleva in Climate Change on May 17, 2013

Scientists from the University of Queensland conducted a survey based on 30,000 scientific peer-reviewed papers published over the past 20 years, identifying that 97.1% of the studies found climate change to be caused by human activities. The findings were published in the journal Environmental Research Letters earlier this week. It was concluded that among scientists, [...]

Vegetarian Diet Key to Curbing Global Warming

Posted by Leigh Kim in Climate Change on May 10, 2013

A recent Cornell University concluded that a global shift toward a vegetarian diet is extremely important in order to combat the worst effects of climate change. Environmentalists stress the need for the general public to understand the connection between land use and the environment. The United Nations has declared that raising animals for food is [...]

Natural Disturbancies Included in Climate Mitigation Strategies

Posted by Mila Luleva in Climate Change on May 9, 2013

A study by researchers at the Joint Global Change Research Institute at Maryland determined that successful climate mitigation strategies in the future should take into account natural disturbances such as fires and hurricanes, which have impact on world’s forested areas. Forests and other ecosystems that control the global carbon cycle are these that are affected by [...]

Impact of Methane Emissions On Climate Understated

Posted by Mila Luleva in Climate Change on May 9, 2013

The impact of methane as a greenhouse gas has been severely understated, as the amount that can be released through fracking has been projected for an 100-year period. Considering that emitted methane can last in the environment for just over eight years, governmental decisions about shale gas exploration have been highly criticised. Politicians are said [...]

Behavior of Marine Microbes Reveals Changes in Global Carbon Cycle

Posted by Mila Luleva in Climate Change on May 1, 2013

A team of scientists from the Lawrence Livermore National Laboratory (LLNL) was granted $1 million by the Gordon and Betty Moore Foundation Marine Microbiology Initiative, to study changes in the carbon cycle due to food, consumed by marine microbes. The method, which will be tested by Xavier Mayali, Jennifer Pett-Ridge, both from LLNL, and a team [...]

Particles Emitted by Green Plants Form Clouds, Reduce Warming

Posted by Mila Luleva in Climate Change on April 29, 2013

A study published in the latest issue of the journal Nature Geoscience emphasises the importance of plants in forming sunshade of clouds, which slow down global warming. Scientists from seven international institutes, who were involved in this research, pointed out that this seemingly small effect of forests could reduce warming by as much as 30% [...]

Adoption of Clean Energy Too Slow to Limit Global Warming

Posted by Leigh Kim in Energy news on April 20, 2013

On Wednesday, the International Energy Agency (IEA) said that low-carbon energy development is progressing far too slowly to have any limiting effect on global warming. Governments are not taking quick enough action, and power generation is still dominated by the fossil fuel industry. Experts have warned that the goal of limiting the global temperature rise [...]

NOAA Study Demonstrates Global Warming Over Land is Real

Posted by Leigh Kim in Climate Change on April 15, 2013

A new study by the National Oceanic and Atmospheric Administration (NOAA) demonstrates that concerns about global warming over land are legitimate. Gilbert Compo, a scientist at NOAA’s University of Colorado Cooperative Institute for Research in Environmental Sciences used a physically-based data assimilation system, 20th Century Reanalysis (20CR) to evaluate the accuracy of global warming theories. [...]

Climate Change Expected to Have Much More Severe Effects, Economist Warns

Posted by Mila Luleva in Climate Change on April 4, 2013

British economist, Nicholas Stern, author of of the most significant and prominent studies on climate change in the last decade, warns that global warming will be much more severe and detrimental than predicted. Stern is a former chief economist for the World bank. In 2006, he released a study on the future cost of climate [...]

Antarctica’s Ice Cover Thickens Due to Climate Change, Affects Sea Level Rise

Posted by Mila Luleva in Climate Change on April 1, 2013

Scientists explain why sea ice around Antarctica is becoming thicker despite the rise in global temperatures in a new study published in the latest issue of Nature Geoscience. During the summer months, ice sheets melt and cause upwelling of fresh water. This water floats on top of the warmer salty water in the form of a [...]

‘Greener’ Arctic Will Cause Raise in Global Temperature, Study Claims

Posted by Mila Luleva in Climate Change on April 1, 2013

According to recent research published in Nature Climate Change earlier this week, The Arctic is about to become ‘greener’ due to global rise in temperatures. The team, led by Richard Pearson, a research scientist at the American Museum of Natural History’s Center for Biodiversity and Conservation, conducted a series of model simulations based on data [...]

Rising CO2 Levels May Lead to Mass Extinction of Species

Posted by Leigh Kim in Climate Change on March 23, 2013

Based upon the levels of CO2 in the atmosphere, which could continue to be released, the Earth may be heading toward conditions like those of the Paleocene-Eocene event. If this is the case, species might not be able to adapt to the extreme rate of current rise in greenhouse gases and temperatures. The incredible rate [...]
