  • Magnetic liquids improve energy efficiency of buildings
    on January 16, 2018 at 2:36 pm

    Climate protection and the reduction of carbon dioxide emissions have been on top of global development agendas. Accordingly, research and development projects have been conducted on national and international levels, which aim for the improvement of the CO2-footprint in diverse processes. Apart from particularly energy-intensive sectors of the industry, the building sector in particular is among the biggest CO2-emmitters: from residential homes, manufacturing facilities and storage depots to big commercial buildings, about 40 percent of the energy consumption within the EU are due to the heating, cooling, air conditioning and lighting of buildings. […]

  • Unexpected environmental source of methane discovered
    on January 15, 2018 at 5:05 pm

    Roughly 10 percent of nitrogen-fixing microorganisms contain the genetic code for manufacturing a back-up enzyme, called iron iron-only nitrogenase, to do their job. New research reveals that this enzyme allows these microorganisms to convert nitrogen gas to ammonia and carbon dioxide into methane at the same time. This enzymatic pathway is a previously unknown route for the natural biological production of methane. […]

  • Jet stream changes since 1960s linked to more extreme weather
    on January 12, 2018 at 2:12 pm

    Increased fluctuations in the path of the North Atlantic jet stream since the 1960s coincide with more extreme weather events in Europe such as heat waves, wildfires and flooding. The new research is the first reconstruction of historical changes in the North Atlantic jet stream prior to the 20th century. By using tree rings, the researchers developed a historical look at the position of the North Atlantic jet back to 1725. […]

  • Rising CO2 is causing trouble in freshwaters too, study suggests
    on January 11, 2018 at 7:17 pm

    As carbon dioxide (CO2) levels in the atmosphere rise, more CO2 gets absorbed into seawater. As a result, the world's oceans have grown more acidic over time, causing a wide range of well-documented problems for marine animals and ecosystems. Now, researchers present some of the first evidence that similar things are happening in freshwaters too. […]

  • Climate impacts of deforestation
    on January 11, 2018 at 4:53 pm

    Deforestation is likely to warm the climate even more than originally thought, scientists warn. Research has found reactive gases emitted by trees and vegetation have an overall cooling effect on our climate, meaning deforestation would lead to higher temperatures than previously anticipated as less of the gases would be created. […]

  • As climate is warming up, more bird nests are destroyed in Finnish farmland
    on January 11, 2018 at 3:08 pm

    A new study shows that birds have shifted the time of their breeding much faster than the farmers are anticipating their sowing times in Finnish farmland. This means that more birds are nowadays laying their eggs on fields that are still to be sown, a mismatch in timing that is most likely fatal for the bird nests. […]

  • Hiding from a warmer climate in the forest
    on January 11, 2018 at 1:49 pm

    Global warming threatens forest plants adapted to cooler temperatures. An international team of scientists have unraveled where these species could survive within colder spots in the same forest.

  • Adaptation now: River flood risks increase around the globe under future warming
    on January 10, 2018 at 7:13 pm

    Rainfall changes caused by global warming will increase river flood risks across the globe. Already today, fluvial floods are among the most common and devastating natural disasters. Scientists have now calculated the required increase in flood protection until the 2040s worldwide, breaking it down to single regions and cities. They find that the need for adaptation is greatest in the US, parts of India and Africa, Indonesia, and in Central Europe including Germany. Inaction would expose many millions of people to severe flooding. […]

  • Body size of marine plankton, currents keys to dispersal in ocean
    on January 10, 2018 at 6:23 pm

    A new international study found that the size of plankton, and the strength and direction of currents, are key to how they are dispersed in the ocean -- much more so than physical conditions including differences in temperature, salinity and nutrient availability. […]

  • Spotty coverage: Climate models underestimate cooling effect of daily cloud cycle
    on January 9, 2018 at 5:49 pm

    Researchers have found that the climate models scientists use to project future conditions on our planet underestimate the cooling effect that clouds have on a daily basis, which results in warmer, drier conditions than might actually occur. The researchers found that inaccuracies in accounting for the daily cloud cycle did not seem to invalidate climate projections, but did increase the margin of error for understanding how climate change will affect us. […]

  • Lake Michigan waterfowl botulism deaths linked to warm waters, algae
    on January 9, 2018 at 2:02 pm

    Volunteers tracked bird deaths along Lake Michigan from 2010 to 2013 to discover what conditions lead to large die-offs. The researchers found that warm waters and algae -- both of which have become more frequent over the years -- tended to precede bird deaths, likely because they promoted the growth of botulism toxin-producing bacteria.
