NASA study predicts devastating droughts during the last half of the century

By - February 17, 2015 2 Pictures
A new NASA study is predicting the occurrence of severe "megadroughts" across the United States in the second half of this century, that are set to be more extreme and prolonged than any droughts that have taken place in the region for the past 1,000 years. According to the study, one of the key driving forces behind the devastating droughts will be the prolific creation of human-produced greenhouse gasses. Read More

ESA successfully tests FLEX instrument, designed to create maps of photosynthetic activity

By - February 4, 2015 1 Picture
The European Space Agency (ESA) has successfully tested its Fluorescence Explorer mission (FLEX), which is vying for a spot on the organisation’s eight Earth Explorer satellite. The mission, which aims to create global maps of photosynthetic activity, will allow for the identification of vegetation suffering degrees of stress that simply aren’t visible to the human eye. It has the potential to significantly further our understanding of the global carbon cycle, and could have an impact on agricultural management. Read More

New study finds parallels between past and present climate change

By - December 17, 2014 4 Pictures
There's an element of déjà vu in the most recent political news on climate change: UN-led talks, like the recent Lima summit, that end with disgruntled environmentalists and plans for yet another summit. At this point, our best hope is to mitigate the effects of global warming (which is occurring faster than previously thought) and, if possible, keep temperature rises to a maximum of 2° C (3.6° F). While the future of the planet looks uncertain with unpredictable climate patterns, U.S researchers looking to the past to gain a better understanding of modern climate change have found the rate of modern, human-caused global warming resembles that which occurred almost 56 million years ago much more closely than previously thought.

MIT's new cement recipe could cut carbon emissions by more than half

By - September 28, 2014 1 Picture
As one of our most relied upon construction materials, concrete makes a significant contribution to our overall carbon emissions. Calcium-based substances are heated at high temperatures to form the cement, a process that produces carbon dioxide. But by slightly altering the quantities of materials used, scientists from MIT have uncovered a new method of cement mixing that could reduce these emissions by more than half. Read More

Sun’s activity shown to influence natural climate change

By - August 19, 2014 1 Picture
In a new study that may greatly add to our understanding of the drivers behind climate change, researchers from Lund University in Sweden claim to have accurately reconstructed solar activity levels during the last ice age. By analyzing trace elements in ice core samples in Greenland and cave mineral formations in China, the scientists assert that regional climate is more influenced by the sun than previously thought.

Detecting industrial pollution could be an effective approach to finding ET

By - July 31, 2014 1 Picture
According to researchers at the Harvard-Smithsonian Center for Astrophysics (CfA), we might soon be able to detect hints of technologically advanced alien civilizations by measuring high levels of polluting gases in the atmospheres of distant exoplanets. The approach should become viable soon after the James Webb Space Telescope (JWST) is launched in late 2018. Read More
