There is a risk that severity of epidemics of some wheat diseases may increase within the next ten to twenty years due to the impacts of climate change according to a study by international researchers. The researchers carried out a survey in China to establish a link between weather and the severity of epidemics of fusarium ear blight on the wheat crops.
Scientists have produced a synthetic air reference standard which can be used to accurately measure levels of carbon dioxide and methane in the atmosphere. This will greatly help scientists contribute to our understanding of climate change.
The Arctic is home to a growing number of whales and ships, and to populations of sub-Arctic whales that are expanding their territory into newly ice-free Arctic waters. A three-year survey of whales in the Bering Strait reveals that many species of whales are using the narrow waterway, while shipping and commercial traffic also increase.
Computer simulations have shown that offshore wind farms with thousands of wind turbines could have sapped the power of three real-life hurricanes, significantly decreasing their winds and accompanying storm surge, and possibly preventing billions of dollars in damages.
Researchers have studied with computer simulations the long-term global consequences of several 'climate engineering' methods. They show that all the proposed methods would either be unable to significantly reduce global warming if CO2 emissions remain high, or they could not be stopped without causing dangerous climate disruption.
The use of rapeseed cake in the production of livestock feed cuts methane and carbon dioxide emissions by up to 13%, according to the initial results of new research. Specifically, the incorporation of this oilseed plant into animal food cuts methane emissions by between 6% and 13% and carbon dioxide emissions by between 6.8% and 13.6%.
Scientists have debunked two big myths around climate change by proving firstly, that despite predictions, tropical storms are not increasing in number. However, they are shifting, and South Africa could be at increased risk of being directly impacted by tropical cyclones within the next 40 years.
The projected transition of livestock systems from pure grazing diets to diets supplemented by higher quality feeds will cut greenhouse gas emissions from land use change globally by as much as 23 percent by 2030, while improving food availability and farmers' income, shows new research.
As climate changes, Alaska fisheries may depend on winter survival of plankton, oceanographer suggests
As the climate warms, the productivity of Alaska fisheries will be increasingly dependent on the survival rate of plankton through the winter months, new research by a large team of scientists suggests. And warming temperatures may make it difficult for them to survive the season.
Volcanic eruptions in the early part of the 21st century have cooled the planet, according to a new study. This cooling partly offset the warming produced by greenhouse gases.
