Coastal cities face rising risk of flood losses, study says
The world's 136 largest coastal cities could risk combined annual losses of $1 trillion (750 billion euros) from floods by 2050 unless they drastically raise their defences, a study warned Sunday.
How do you feed 9 billion people?
An international team of scientists has developed crop models to better forecast food production to feed a growing population – projected to reach 9 billion by mid-century – in the face of climate change.
Cities affect temperatures for thousands of miles
Even if you live more than 1,000 miles from the nearest large city, it could be affecting your weather. In a new study that shows the extent to which human activities are influencing the atmosphere, scientists ...
Enough wind to power global energy demand, new research says
There is enough energy available in winds to meet all of the world's demand. Atmospheric turbines that convert steadier and faster high-altitude winds into energy could generate even more power than ground- ...
Marine reserves enhance resilience to climate change
A new study, led by a University of Southampton scientist, highlights the potential for fish communities in marine reserves to resist climate change impacts better than communities on fished coasts.
Even if emissions stop, carbon dioxide could warm Earth for centuries
Even if carbon dioxide emissions came to a sudden halt, the carbon dioxide already in Earth's atmosphere could continue to warm our planet for hundreds of years, according to Princeton University-led research ...
Research highlights urgency of reducing carbon dioxide emissions
(Phys.org) —Just-published research from Victoria University of Wellington and the University of Oxford highlights the urgency of reducing global emissions of carbon dioxide.
Paths out of uncertainty: Increasing extreme confidence
Long-term and average changes are in the focus of the discussion on climate change: globally, as the different scientific climate models all predict, it will be warmer on Earth at the end of the century. For decision-makers ...
Ocean acidification: First demonstration that ocean's CO2 uptake can impair digestion in a marine animal
Ocean acidification impairs digestion in marine organisms, according to a new study published in the journal Nature Climate Change. Researchers from Sweden and Germany have studied the larval stage of gre ...
How do we balance needs of energy, water, and climate?
In deciding how best to meet the world's growing needs for energy, the answers depend crucially on how the question is framed. Looking for the most cost-effective path provides one set of answers; including the need to curtail ...
New study tests 90-year old hybridisation theory
(Phys.org) —Massey University researchers have the first convincing evidence that interbreeding between closely related species (hybridisation) can aid plants during periods of environmental change.
People don't put a high value on climate protection
(Phys.org) —People are bad at getting a grip on collective risks. Climate change is a good example of this: the annual climate summits have so far not led to specific measures. The reason for this is that people attach ...
Delayed gratification hurts climate change cooperation
Time is a huge impediment when it comes to working together to halt the effects of climate change, new research suggests.
China's synthetic gas plants would be greenhouse giants
Coal-powered synthetic natural gas plants being planned in China would produce seven times more greenhouse gas emissions than conventional natural gas plants, and use up to 100 times the water as shale gas production, according ...
