How ocean acidification is affecting marine life

Climate Change News - ENN - June 16, 2014 - 6:39am
A new study by researchers at the University of Bristol and Plymouth Marine Laboratory has shed light on how different species of marine organisms are reacting to ocean acidification. Since the Industrial Revolution, nearly 30 per cent of all the carbon dioxide produced by manmade emissions has been absorbed by the ocean, causing a drop in pH of ocean surface waters: ocean acidification.

Nasa Prepares To Launch First Satellite Dedicated To Measuring CO2 Levels

Climate Change News - ENN - June 13, 2014 - 5:49pm
NASA's first spacecraft dedicated to measuring carbon dioxide levels in Earth’s atmosphere is in final preparations for a July 1 launch from Vandenberg Air Force Base, California. The Orbiting Carbon Observatory-2 (OCO-2) mission will provide a more complete, global picture of the human and natural sources of carbon dioxide, as well as their "sinks," the natural ocean and land processes by which carbon dioxide is pulled out of Earth’s atmosphere and stored.

Penguin populations may have benefited from historic climate warming

Climate Change News - ENN - June 13, 2014 - 10:10am
While penguins have adapted to extremely cold weather, harsh winters are still difficult for populations especially when it comes to breeding and finding food. So with warming climates on the horizon, are penguin populations going to be better off? Not necessarily. However, a new study does reveal that penguin populations over the last 30,000 years have benefitted in some ways from climate warming and retreating ice. An international team, led by scientists from the University of Southampton and Oxford University, has used a genetic technique to estimate when current genetic diversity arose in penguins and to recreate past population sizes.

Wasted heat from air conditioners causes warmer nighttime temperatures

Regulatory news - ENN - June 12, 2014 - 9:01am
With summer temperatures fast approaching, households across the country are installing and prepping air conditioning units in anticipation of hot, sticky weather. However, a potentially brutal cycle may be in store if summertime extreme-heat days are projected to become more frequent and intense as a result of climate change. According to a new study conducted in Phoenix by Arizona State University researchers, so much wasted heat is emitted by air conditioning units that it actually raises the city's outdoor temperature at night by 1-2.7 degrees! Consequently, these warmer temperatures may encourage individuals to further their demands and energy use of their air conditioners. The research, published last month in the Journal of Geophysical Research, investigates the effects of air-conditioning systems on air temperature and examines their electricity consumption for a semiarid urban environment.

Using too much fertilizer is bad for crops AND bad for climate!

Climate Change News - ENN - June 12, 2014 - 7:30am
Using too much fertilizer is a very bad idea. It doesn't help crops, and in fact can be harmful to them. Excess fertilizer runs off and contributes to river and stream contamination and a new study shows that it is bad for the climate too! But farmers sometimes think that if some is good, more MUST be better! Helping farmers around the globe apply more precise amounts of fertilizer nitrogen is a great objective that can improve crop yields, reduce pollution, and combat climate change. That's the conclusion of a study published this week in the journal Proceedings of the National Academy of Sciences. In the paper, researchers at Michigan State University (MSU) provide an improved prediction of nitrogen fertilizer's contribution to greenhouse gas emissions from agricultural fields.

How forest debris affects freshwater food chains

While one may think that forest and lake ecosystems are two separate networks, new research shows how forest debris is an important contributor to freshwater food chains. How? Debris in the form of organic carbon from trees washes into freshwater lakes, which consequently supplements the diets of microscopic zooplankton and the fish that feed on them. Researchers at the University of Cambridge conducted a study at Daisy Lake in Ontario, Canadian by observing Yellow Perch fish from different parts of the water body with varying degrees of surrounding forest cover. Carbon from forest debris has a different elemental mass than carbon produced by algae in the aquatic food chain. By analyzing the young Perch that had been born that year, scientists were able to determine that at least 34% of the fish biomass comes from vegetation, increasing to 66% in areas surrounded by rich forest. Essentially, the more forest around the edge of the lake, the fatter the fish in that part of the lake were. Similarly, the sparser the forest leaves, the smaller the fish.

Saving bees with spider venom?

With Europe and the United States slow to ban the pesticides that science says is probably drastically harming our bee populations, could one of the world's most venomous spiders hold one solution to saving our pollinators?

What does the temperature feel like on Mars?

Even though daytime temperatures in the tropics of Mars can be about –20°C, a summer afternoon there might feel about the same as an average winter day in southern England or Minneapolis. That’s because there’s virtually no wind chill on the Red Planet, according to a new study—the first to give an accurate sense of what it might feel like to spend a day walking about on our celestial neighbor. "I hadn't really thought about this before, but I'm not surprised," says Maurice Bluestein, a biomedical engineer and wind chill expert recently retired from Indiana University–Purdue University Indianapolis. The new findings, he says, "will be useful, as people planning to colonize Mars need to know what they’re getting themselves into."

Geothermal heat is causing the West Antarctic glacier to melt faster

Climate Change News - ENN - June 10, 2014 - 8:37am
Thwaites Glacier, the large, rapidly changing outlet of the West Antarctic Ice Sheet, is not only being eroded by the ocean, it's being melted from below by geothermal heat, researchers at the Institute for Geophysics at The University of Texas at Austin (UTIG) report in the current edition of the Proceedings of the National Academy of Sciences. The findings significantly change the understanding of conditions beneath the West Antarctic Ice Sheet where accurate information has previously been unobtainable.

Playing God with plants!

Climate Change News - ENN - June 9, 2014 - 3:55pm
Plants make and store energy from the sun using a process called photosynthesis. This process has evolved on planet earth over millions of years. How can we mess with plant DNA to improve on what nature has evolved? Three research teams--each comprised of scientists from the United States and the United Kingdom--have been awarded a second round of funding to continue research on news ways to improve the efficiency of photosynthesis. The ultimate goal of this potentially high-impact research is to develop methods to increase yields of important crops that are harvested for food and sustainable biofuels. But if this research is successful, it may also be used to support reforestation efforts and efforts to increase the productivity of trees for the manufacture of wood and paper and thousands of other products that are derived from wood and chemicals extracted from trees. Another reason why photosynthesis is an important research topic: It has made the Earth hospitable for life by generating food and oxygen.

In cutting deforestation, Brazil leads world in reducing emissions

Climate Change News - ENN - June 9, 2014 - 9:53am
Brazil's success in reducing deforestation in the world's largest rainforest has been much heralded, but progress may stall unless farmers, ranchers and other land users in the region are provided incentives to further improve the environmental sustainability of their operations, argues a study published this week in the journal Science.

Bottom feeding fish helping the fight against Global Warming

Climate Change News - ENN - June 9, 2014 - 8:48am
Over-fishing is already a concerning problem, but new research indicates that not only could it mean losing fish species, it could also contribute to global warming more than we'd previously thought. That's because researchers from the Marine Institute and the University of Southampton have found that fish that feed on our ocean floor and do not come to the surface actually act as carbon sinks. Other examples of naturally occurring carbon sinks include forests and, indeed, the oceans themselves. What’s more, the UK-based researchers have found that deep-sea fish might be capturing more than a million tons of carbon dioxide from UK and Irish waters.

Massive rocky planet challenges traditional views of planet formation

Astronomers have discovered a rocky planet that weighs 17 times as much as Earth and is more than twice as large in size. This discovery has planet formation theorists challenged to explain how such a world could have formed. "We were very surprised when we realized what we had found," said astronomer Xavier Dumusque of the Harvard-Smithsonian Center for Astrophysics, Cambridge, Massachusetts, who led the analysis using data originally collected by NASA's Kepler space telescope.

Archaeological expedition reveals first fossil-record evidence of forest fire ecology

Fossils can reveal an incredible amount of information. From what kind of organisms lived when and where to how they may have evolved over time. And now a new discovery of plant fossils with abundant fossilized charcoal reveals something new about prehistoric forest fires. Forest fires affect ecosystems differently and despite the fact that organisms and plant life have had to adapt to cope with these natural phenomena, new research shows that forests have been recovering from fires in the same manner as they did 66 million years ago.

China and Coal

Climate Change News - ENN - June 6, 2014 - 7:56am
Coal consumption in China is likely to dwindle rapidly, writes Alex Kirby, leaving its own mining sector and foreign coal exporters in serious trouble. Australia and Indonesia are at greatest risk as China may soon stop importing any coal at all. Investors need to dispel any belief that Chinese coal demand is insatiable, and integrate this transition into their decision-making. Analysts believe that China - the world's largest producer and consumer of coal, accounting for almost half of global consumption - could be close to making an abrupt, drastic change of track.

CO2 emissions in EU down significantly

Climate Change News - ENN - June 5, 2014 - 4:47pm
The European Union’s greenhouse gas emissions have fallen by 19.2% compared to 1990s levels, according to the European Environment Agency. EU emissions dropped 1.3% in 2012, reaching their lowest level ever recorded, according to data reported to the United Nations by the EEA. The bloc's greenhouse gas output decreased by 1082 megatonnes since 1990, more than the combined emissions of Italy and United Kingdom in 2012.
