Global Warming

The new method looks for specific isotopes that point to the origins of methane samples (I...

An MIT-led team of researchers has developed an instrument capable of quickly and accurately analyzing samples of methane, pinpointing how they were formed. The breakthrough could give scientists a greater understanding of the role the gas plays in global warming.  Read More

30-cm (11.8-in)-deep moisture projection based on NASA's high carbon emission scenario in ...

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

FLEX aims to detect abnormal peaks of florescence from space, providing warnings of stress...

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

The banded sedimentary rock layers of the Willwood formation in Wyoming provide clues as t...

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.  Read More

The new CryoSat measurements show a 6.4 percent decrease in the volume of Arctic sea ice (...

The European Space Agency’s CryoSat mission has returned its latest map of Arctic sea ice volumes, recording a slight decrease in thickness over previous measurements. The data flies in the face of the previous downward trend, which was much greater, but is unlikely to indicate a shift in the accepted pattern of degradation.  Read More

New research suggests that it takes just 10 years for CO2 emissions to have maximum effect...

Any given CO2 emission will have its maximum warming effect just 10 years later, new research from the Carnegie Institution for Science shows. The Institute of Physics (IOP) says this research, published in full on the web today, has "dispelled a common misconception" that the warming effects of CO2 emissions aren't felt for decades.  Read More

A study carried out at MIT suggests that altering the quantities of materials in cement mi...

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

A new study from Lund University asserts that regional climate is influenced by the sun (I...

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.  Read More

Scientists suggest looking for industrial pollution as a new way of searching for extrater...

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

A new study predicts that global crop yields could fall by up to ten percent in the next 3...

A new study has examined the potentially disastrous implications that a combination of global warming and air pollution could have on crop yields by the year 2050. The research is one of the first projects to take into account a combination of the two dangers, and highlights the humanitarian crisis that could arise should the threat not be tackled head-on.  Read More
