A new analysis indicates that the UK’s CO2 output is at a record low, and it’s largely down to one major action: a reduction in coal use.

The hidden toll that subsidies for electricity, fossil fuels, and transport have on social welfare, economic growth and technological innovation needs to be exposed through better research says a new paper in Ecological Economics by Benjamin K Sovacool.

Energy subsidies, which have mostly supported fossil fuels and nuclear power over the previous half century, have historically kept energy prices artificially low, compared to market rates. But they come at a high cost to governments and taxpayers. The Indian government, for example, spends as much as it does on fuel subsidies for kerosene and liquid propane, used to light rural houses, as it does on education. India subsidises fossil energy consumption by $21 billion every year, which works out at $16 per person. Given that 500 million of its people live on less than $2 per day, this is a surprisingly large amount.

Accurately predicting the weather - at short and long time scales - is among the most complex and important challenges faced by science. Protecting the nation’s security and economic well-being will increasingly rely on improved skill in forecasting weather, weather-driven events like floods and droughts, and long-term shifts in weather, ocean and sea-ice patterns.

Climate projections for West Africa show that crop yields and grass for livestock grazing are likely to decline in the future. But a new study in the journal Global Environmental Change shows that when ineffective institutions and political instability limit investment in agriculture climate change would have greater impacts on regional food security.

West Africa is a major producer of crops such as cassava, millet, and sorghum but in the future, regional production may not be able to meet the growing demand for food and livestock feed. “How and to what extent the region’s agricultural sector develops in the future will have profound implications for the livelihoods of millions of people,” says IIASA researcher Amanda Palazzo, who led the study.

Environmental scientists and policymakers value long-term research to an extent that far outstrips the amount of funding awarded for it, according to a study published today.

Graduate students and faculty members in the Oregon State University College of Science were part of a collaboration that evaluated the perceived benefits of long-term ecological and environmental studies – known as LTEES – to both researchers and those who determine environmental policy. 

Most strategies to combat climate change concentrate on reducing greenhouse gas emissions by substituting non-carbon energy sources for fossil fuels, but a task force commissioned in June 2016 by former U.S. Secretary of Energy Ernest Moniz proposed a framework in December 2016 for evaluating research and development on two additional strategies: recycling carbon dioxide and removing large amounts of carbon dioxide from the atmosphere. These strategies were developed under a single framework with the goal to produce an overall emissions reduction for the Earth of at least one billion tons of carbon dioxide per year.

Forests are set to play a major role in meeting the objectives of the Paris Climate Agreement - however, accurately monitoring progress toward the 'below 2°C' target requires a consistent approach to measuring the impact of forests on greenhouse gas (GHG) emissions.

In a paper published in the journal, Nature Climate Change: Key role of forests in meeting climate targets but science needed for credible mitigation, scientists are calling for robust, transparent and credible data to track the real mitigation potential of forests.

River diversions are a common coastal wetland restoration tool, but recent research, conducted by U.S. Geological Survey in collaboration with researchers in Louisiana State University’s Department of Civil and Environmental Engineering and the LSU AgCenter, has shown that large-scale Mississippi River diversions may significantly change water quality in estuaries, affecting economically important shellfish and fish species.

Global climate change is affecting our planet and mankind; climate science is thus instrumental in informing policy makers about its dangers, and in suggesting emission limits. Science also shows that staying within limits, while meeting the aspirations of a growing global population requires fundamental changes in energy conversion and storage. The majority of low-carbon technology innovation observed in the last decades, such as the 85% cost reduction in photovoltaic cell production since 2000, was driven by largely uncoordinated national policies. These included research incentives in Japan and the U.S., feed-in tariffs in Germany, and tax breaks in the U.S.

Building the wall that Donald Trump has ordered on January 25th, as one of his first actions as US president, will put on risk more than 50 animal species that share the ecosystem along the border between the United States and Mexico, scientists from various countries have warned.
 
Since 2006, 1,100 kilometers of barriers covering more than 30 per cent of the border between the countries have been built. The newest executive order commands the “immediate construction of a physical wall”, stating that ‘wall’ means “a physical barrier, continuous and impassable”.
