The important role of diatoms in the oceans
May 29, 2015 09:07 AM - University of Washington via ScienceDaily.
A glass of seawater is teeming with life, and recent research reveals more about what ocean water contains. Microscopic creatures in the world's oceans weigh more than all of the fish in the sea and produce about half of Earth's oxygen.
Yet the ecology of marine microbes, which are crucial for everything from absorbing carbon dioxide from the air to regulating the productivity of major fisheries, are only beginning to be understood.
Why Heat is Accelerating the California Drought
May 28, 2015 04:03 PM - USGS Newsroom
Although record low precipitation has been the main driver of one of the worst droughts in California history, abnormally high temperatures have also played an important role in amplifying its adverse effects, according to a recent study by the U.S. Geological Survey and university partners.
Greening the Airline Industry
May 28, 2015 11:06 AM - EurActiv
The airline sector is trying to lessen its carbon footprint. In mid-June, the Paris Air Show will host the COP21 seen from the sky conference. Boeing and Airbus are concentrating their commercial efforts on the environment, which is now a selling point. “CO2 affects our ability to grow," said Jonathon Counsell, Head of Environment for British Airways, during a day dedicated to the environment organised by Airbus at its Toulouse site. Airlines make up 2% of worldwide CO2 emissions. But the doubling of passengers every 15 years has made it a growing source of greenhouse gases.
Montreal Protocol Leads to Better Ozone
May 27, 2015 07:53 AM - University of Leeds
We are already reaping the rewards of the Montreal Protocol, with the ozone layer in much better shape than it would have been without the UN treaty, according to a new study in Nature Communications. Study lead author Professor Martyn Chipperfield, from the School of Earth & Environment at the University of Leeds, said: “Our research confirms the importance of the Montreal Protocol and shows that we have already had real benefits. We knew that it would save us from large ozone loss 'in the future', but in fact we are already past the point when things would have become noticeably worse.”
Stable Antarctic glaciers are now melting
May 24, 2015 08:21 AM - Bert Wouters, The Ecologist
A dramatic shift has taken place in the glaciers of the southern Antarctic peninsula, writes Bert Wouters. Six years ago these previously stable bodies suddenly stated shedding 60 cubic kilometres of ice per year into the ocean. A stark warning of further surprises to come?
The fact that so many glaciers in such a large region suddenly started to lose ice came as a surprise. It shows a very fast response of the ice sheet: in just a few years everything changed.
Climate change and human rights
May 22, 2015 07:15 AM - Eniko Horvath, Triple Pundit
Last month, a Peruvian farmer called on German energy company RWE to pay its fair share to protect his home from imminent flooding caused by a glacial lake melted by global warming. “For a long time, my father and I have thought that those who cause climate change should help solve the problems it causes,” Saul Luciano Lliuya told the Guardian. He holds that RWE, one of Europe’s largest emitters of carbon, has contributed to the greenhouse effect causing glacial melting that endangers his home, along with many others in the city of Huaraz.
Lliuya’s story illustrates the tangible human impacts of climate change, which can easily be forgotten amidst high-level debates over carbon emissions reductions. This is a key year for climate action by both governments and companies.
Can Ice Loss Affect Gravity?
May 21, 2015 04:14 PM - University of Bristol
A group of scientists, led by a team from the University of Bristol, has observed a sudden increase of ice loss in a previously stable region of Antarctica. The research is published today in Science.
Coal power in Turkey to double if Turkey's plans go forward
May 20, 2015 08:26 AM - EurActiv
Turkey is planning to double its coal power capacity in four years, the third largest investment in the polluting fossil fuel in the world, health campaigners have warned.
The Health and Environment Alliance (HEAL) today called on the European Union to promote sustainable development in Turkey and end lending for new coal projects.
Future climate of the Midwest hard to predict
May 18, 2015 03:02 PM - Dartmouth College via ScienceDaily.
Will climate change make the U.S. Midwest drier or wetter during the summer growing season? A new Dartmouth-led study finds that the answer remains uncertain.
The findings are important given the Midwest's agricultural output is critical to the U.S. economy and global food security.
The study appears in the journal Water Resources Research. The study included researchers from Dartmouth College, Columbia University, National University of Singapore and Massachusetts Institute of Technology.
US Exposure to Extreme Heat is on the Rise
May 18, 2015 02:33 PM - UCAR AtmosNews
U.S. residents' exposure to extreme heat could increase four- to six-fold by mid-century, due to both a warming climate and a population that's growing especially fast in the hottest regions of the country, according to new research. The study, by researchers at the National Center for Atmospheric Research (NCAR) and the City University of New York (CUNY), highlights the importance of considering societal changes when trying to determine future climate impacts.
