Greenhouse Gas Emissions from US Corn Belt have been Underestimated

Climate Change News - ENN - July 29, 2015 - 9:55am
Estimates of how much nitrous oxide, a significant greenhouse gas and stratospheric ozone-depleting substance, is being emitted in the central United States have been too low by as much as 40 percent, a new study led by University of Minnesota scientists shows.

How Corn Became King

Climate Change News - ENN - July 28, 2015 - 10:12am
Ten thousand years ago, a golden grain got naked, brought people together and grew to become one of the top agricultural commodities on the planet.Now, University of Wisconsin-Madison researchers have found that just a single letter change in the genetic script of corn's ancestor, teosinte, helped make it all possible.Publishing in the journal Genetics this month, UW-Madison genetics Professor John Doebley and a team of researchers describe how, during the domestication of corn, a single nucleotide change in the teosinte glume architectural gene (tga1) stripped away the hard, inedible casing of this wild grass, ultimately exposing the edible golden kernel.

California Farmers Switch to Less Thirsty Crops

Climate Change News - ENN - July 28, 2015 - 9:56am
Water scarcity is driving California farmers to plant different crops. Growers are switching to more profitable, less-thirsty fruits, vegetables and nuts.

ACC Welcomes House Roundtable on Impacts of EPA Ozone Proposal

Environmental Regulations - July 28, 2015 - 6:07am
We remain concerned about how businesses, households and communities will be affected by a lower ozone standard, which is not supported by the health science evidence and could slow or stall manufacturing growth.

Arctic ice growth doesn't disprove climate change

Climate Change News - ENN - July 27, 2015 - 9:52am
New data shows that in 2013 Arctic ice actually grew rather than retreating as climate change models had predicted. Far from proving climate change is a myth or that ice retreat has ended, as skeptics are now claiming, this reveals something much more interesting about our warming climate.

New MIT study on the historical climate of the American West

Climate Change News - ENN - July 27, 2015 - 7:56am
All around the deserts of Utah, Nevada, southern Oregon, and eastern California, ancient shorelines line the hillsides above dry valley floors, like bathtub rings — remnants of the lakes once found throughout the region. Even as the ice sheets retreated at the end of the last ice age, 12,000 years ago, the region remained much wetter than it is today. The earliest settlers of the region are likely to have encountered a verdant landscape of springs and wetlands.So just when and why did today’s desert West dry out?

Ocean acidification is impacting phytoplankton now

Climate Change News - ENN - July 26, 2015 - 9:37am
Scientists are warning that ocean acidification is impacting microorganisms in our ocean known as phytoplankton and, as they pay a key role in ocean habitats, any future loss or change in species numbers could impact marine life in a big way.Ocean acidification isn’t always mentioned in conjunction with phytoplankton blooms, and the U.S. Government has been slow to link the two, but MIT researchers say acidification of our oceans could impact phytoplankton in a big way, and that will be bad news for our marine life.

Mangroves help protect against sea level rise

Climate Change News - ENN - July 23, 2015 - 3:28pm
Mangrove forests could play a crucial role in protecting coastal areas from sea level rise caused by climate change, according to new research involving the University of Southampton.

Disaster displacement on the rise

Climate Change News - ENN - July 22, 2015 - 9:54am
In the last seven years, an estimated one person every second has been forced to flee their home by a natural disaster, with 19.3 million people forced to flee their homes in 2014 alone, according to a new report. The research suggests disaster displacement is on the rise, and as policy leaders worldwide advance towards the adoption of a post-2015 global agenda, the time has never been better to address it.

NASA finds Greenland glaciers melting faster than thought

Climate Change News - ENN - July 22, 2015 - 7:49am
Greenland's glaciers flowing into the ocean are grounded deeper below sea level than previously measured, allowing intruding ocean water to badly undercut the glacier faces. That process will raise sea levels around the world much faster than currently estimated, according to a team of researchers led by Eric Rignot of the University of California, Irvine (UCI), and NASA's Jet Propulsion Laboratory, Pasadena, California.The researchers battled rough waters and an onslaught of icebergs for three summers to map the remote channels below Greenland's marine-terminating glaciers for the first time. Their results have been accepted for publication in the journal Geophysical Research Letters and are now available online.

Where does water from rain and snow melt actually go?

Climate Change News - ENN - July 20, 2015 - 10:00am
More than a quarter of the rain and snow that falls on continents reaches the oceans as runoff. Now a new study helps show where the rest goes: two-thirds of the remaining water is released by plants, more than a quarter lands on leaves and evaporates and what’s left evaporates from soil and from lakes, rivers and streams.

Warming impacting bird populations in Hawai'i

Climate Change News - ENN - July 20, 2015 - 8:07am
Hawai‘i, the name alone elicits images of rhythmic traditional dancing, breathtaking azure sea coasts and scenes of vibrant birds flitting through lush jungle canopy. Unfortunately, the future of many native Hawaiian birds looks grim as diseases carried by mosquitoes are due to expand into higher elevation safe zones.A new study published in Global Change Biology, by researchers at the U.S. Geological Survey and the University of Wisconsin-Madison, assesses how global climate change will affect future malaria risk to native Hawaiian bird populations in the coming century.

Does past sea level rise portend future rise from warming?

Climate Change News - ENN - July 19, 2015 - 8:13am
You may have seen claims in recent weeks that historic records show a global temperature rise could give us sea levels 20 feet higher than the norm. How accurate are these claims, and why is it important that we take this issue seriously?The reports are a result of a University of Florida study that was recently published in the journal Science. The researchers, including lead author Andrea Dutton, wanted to investigate how historically Greenland and Antarctic ice sheets have reacted to global temperature rises and therefore get a glimpse of how current climate change might impact our sea levels.

The role of oceanic plankton in cloud formation

Climate Change News - ENN - July 18, 2015 - 7:40am
Nobody knows what our skies looked like before fossil fuel burning began; today, about half the cloud droplets in Northern Hemisphere skies formed around particles of pollution. Cloudy skies help regulate our planet’s climate and yet the answers to many fundamental questions about cloud formation remain hazy.Satellites use chlorophyll’s green color to detect biological activity in the oceans. The lighter-green swirls are a massive December 2010 plankton bloom following ocean currents off Patagonia, at the southern tip of South America.NASA

How clouds get their brightness

How clouds form and how they help set the temperature of the earth are two of the big remaining questions in climate research. Now, a study of clouds over the world's remotest ocean shows that ocean life is responsible for up to half the cloud droplets that pop in and out of existence during summer.

Oceans slowed global temperature rise

Climate Change News - ENN - July 17, 2015 - 10:16am
A new study of ocean temperature measurements shows that in recent years, extra heat from greenhouse gases has been trapped in the subsurface waters of the Pacific and Indian oceans, thus accounting for the slowdown in the global surface temperature increase observed during the past decade, researchers say.

Seaweed that tastes like bacon? Sign me up!

Oregon State University researchers have patented a new strain of a succulent red marine algae called dulse that grows extraordinarily quickly, is packed full of protein and has an unusual trait when it is cooked.This seaweed tastes like bacon.

As species adapt to a warming climate, ecosystems change

Climate Change News - ENN - July 15, 2015 - 8:39am
If it seems like you're pulling more bass than trout out of Ontario's lakes this summer, you probably are.Blame it on the ripple effect of climate change and warming temperatures. Birds migrate earlier, flowers bloom faster, and fish move to newly warmed waters putting local species at risk.To mitigate the trend and support conservation efforts, scientists at the University of Toronto (U of T) are sharing a way to predict which plants or animals may be vulnerable to the arrival of a new species.

Greenland ice sheet melting more rapidly from impact of rainfall

Climate Change News - ENN - July 14, 2015 - 7:24am
According to a new study published in Nature Geoscience, the Greenland ice sheet has been shown to accelerate in response to surface rainfall and melt associated with late-summer and autumnal cyclonic weather events.Samuel Doyle and an international team of colleagues led from Aberystwyth University's Centre for Glaciology combined records of ice motion, water pressure at the ice sheet bed, and river discharge with surface meteorology across the western margin of the Greenland ice sheet and captured the wide-scale effects of an unusual week of warm, wet weather in late August and early September, 2011.
