Climate stabilization: Planting trees cannot replace cutting carbon dioxide emissions

Growing plants and then storing the CO2 they have taken up from the atmosphere is no viable option to counteract unmitigated emissions from fossil fuel burning, a new study shows. The plantations would need to be so large, they would eliminate most natural ecosystems or reduce food production if implemented as a late-regret option in

Bird Migration Patterns Are Getting Wrecked by Climate Change

Birds depend on cues from nature to lead their lives — the length of sunlight, temperature changes, ambient scents. For thousands of years, these cues have been remarkably stable and birds have been remarkably consistent in their migration patterns. But in this era of climate change, those cues are getting scattered and birds are getting

Climate seesaw at the end of the last glacial phase

A change in precipitation at one location may be caused by changes on the other side of the planet. An international team with the participation of the GFZ German Research Centre for Geosciences now investigated Japanese lake sediments to decipher the interplay between local climate changes on the northern hemisphere about 12,000 years ago. Their

The major US TV networks of ABC, CBS, NBC, and Fox News spent a grand total of 50 minutes on climate change last year—combined.

By all accounts, 2016 was an eventful year for the planet. It was the year when a record amount of coral perished in Australia’s Great Barrier Reef, deforestation in the Amazon increased nearly 30%, polar sea ice the size of India disappeared, and of course it got hotter. In fact, it was the hottest year

Extreme weather events linked to climate change impact on the jet stream

Unprecedented summer warmth and flooding, forest fires, drought and torrential rain — extreme weather events are occurring more and more often, but now an international team of climate scientists has found a connection between many extreme weather events and the impact climate change is having on the jet stream. "We came as close as one

The More Climate Skeptics There Are, the Fewer Climate Entrepreneurs

According to an October 2016 Pew poll, only about half of Americans believe that climate change is due to human activity. The U.S. remains home to a considerable number of “climate skeptics,” who clearly impact the politics around the issue, as they are unlikely to support costly actions such as carbon taxes intended to mitigate

Climate change to worsen drought, diminish corn yields in Africa

Nearly 25 percent of the world’s malnourished population lives in sub-Saharan Africa, where more than 300 million people depend on corn, or maize, as their main food source. Maize is the most widely harvested agricultural product in Africa and is grown by small farmers who rely heavily on rainwater rather than irrigation. The crop is

Melting Sea Ice May Be Speeding Nature’s Clock in the Arctic

Spring is coming sooner to some plant species in the low Arctic of Greenland, while other species are delaying their emergence amid warming winters. The changes are associated with diminishing sea ice cover, according to a study published in the journal Biology Letters and led by the University of California, Davis. The timing of seasonal events,

Current climate change models understate the problem, scientists argue

An international team of distinguished scientists, including five members of the National Academies, argues that there are critical components missing from current climate models that inform environmental, climate, and economic policies. The article, published in the National Science Review, describes how the recent growth in resource use, land-use change, emissions, and pollution has made humanity

Researchers Report New Understanding of Global Warming

Researchers know that more, and more dangerous, storms have begun to occur as the climate warms. A team of scientists has reported an underlying explanation, using meteorological satellite data gathered over a 35-year period. The examination of the movement and interaction of mechanical energies across the atmosphere, published Jan. 24 in the journal Nature Communications,

Climate change and sustainable farming: one way to address world hunger

In 2015, the United Nations outlined 17 sustainable-development goals aimed at ending poverty and protecting the planet. By 2030, the U.N. hopes to see those 17 goals stimulate change by addressing economic, social and environmental problems. The International Crop Research Institute for the Semi-Arid Tropics (ICRISAT), based in Hyderabad, India, has been working for the

Climate change to shift global pattern of mild weather

As scientists work to predict how climate change may affect hurricanes, droughts, floods, blizzards and other severe weather, there’s one area that’s been overlooked: mild weather. But no more. NOAA and Princeton University scientists have produced the first global analysis of how climate change may affect the frequency and location of mild weather – days

Under-Employed, Under-Inclusive and Under Threat: How WEF Sees the World in 2017

Economic inequality, societal polarization and intensifying environmental dangers are the top three trends that will shape global developments over the next 10 years, according to the World Economic Forum’s Global Risks Report 2017. In the annual survey, some 750 experts assessed 30 global risks, as well as 13 underlying trends that could amplify them or

Why planting more trees is one of the smartest things a city can do

Trees can make a city sidewalk prettier, sure. But that’s not even their best trick. A growing pile of research suggests that planting more urban trees, if done right, could save tens of thousands of lives around the world each year — by soaking up pollution and cooling down deadly heat waves. In fact, as

Americans believe climate change connected to location and local weather

A new study finds local weather may play an important role in Americans’ belief in climate change. The study, published on Monday, found that Americans’ belief that the earth is warming is related to the frequency of weather-related events they experience, suggesting that local changes in their climate influence their acceptance of this worldwide phenomenon.

Nature already dramatically impacted by climate change, study reveals

Global climate change has already impacted every aspect of life on Earth, from genes to entire ecosystems, according to a new University of Florida study. "We now have evidence that, with only a ~1 degree Celsius of warming globally, major impacts are already being felt in natural systems," said study lead author Brett Scheffers, an
