Extreme weather has limited effect on attitudes toward climate policies

BLOOMINGTON, Ind. -- People who recently experienced severe weather events such as floods, storms and drought are more likely to support policies to adapt to the effects of climate change, according to a new study co-authored by an Indiana University researcher. But the relationship between exposure to extreme weather and support for climate policies is

What changes when you warm the Antarctic Ocean just 1 degree? Lots

After warming a natural seabed in the Antarctic Ocean by just 1° or 2° Celsius, researchers observed massive impacts on a marine assemblage, as growth rates nearly doubled. The findings of what the researchers call the "most realistic ocean warming experiment to date" reported in Current Biology on August 31 show that the effects of

Dramatic changes needed in farming practices to keep pace with climate change

Major changes in agricultural practices will be required to offset increases in nutrient losses due to climate change, according to research published by a Lancaster University-led team. To combat repeated, damaging storm events, which strip agricultural land of soil and nutrients, farmers are already adopting measures to conserve these assets where they are needed. But

Climate change to deplete some US water basins used for irrigation

A new study by MIT climate scientists, economists, and agriculture experts finds that certain hotspots in the country will experience severe reductions in crop yields by 2050, due to climate change’s impact on irrigation. The most adversely affected region, according to the researchers, will be the Southwest. Already a water-stressed part of the country, this

Climate inequalities are moving from North-South to urban-rural

Cities have been recognized as key drivers toward the successful governance of resources and as the front line in combating climate change. But the economic divide between the Global North and South that historically has shaped debates on urbanization and climate change could soon be overshadowed by inequalities related to a potentially stronger disparity between

Climate change could exacerbate economic inequalities in the U.S.

Climate change may make the rich richer and the poor poorer in the United States. Counties in the South face a higher risk of economic downturn due to climate change than their northern counterparts, a new computer simulation predicts. Because southern counties generally host poorer populations, the new findings, reported in the June 30 Science,

Reconciling predictions of climate change

Harvard University researchers have resolved a conflict in estimates of how much the Earth will warm in response to a doubling of carbon dioxide in the atmosphere. That conflict -- between temperature ranges based on global climate models and paleoclimate records and ranges generated from historical observations -- prevented the United Nations' Intergovernmental Panel on

Future of impact, climate investor one, India’s development impact bond, Big Renewables

‘Future of impact’ requires investment, philanthropy — and business as a force for good. As Bill Gates says, “We always overestimate the change that will occur in the next two years and underestimate the change that will occur in the next ten.” For its 10th anniversary last month, Liquidnet For Good hosted “The Future of Impact” forum to

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
