Biofuels reduce greenhouse-gas emissions in comparison to fossil fuels. In the Jan. 4 issue of the journal Science, Smithsonian researchers highlight a new study that factors in environmental costs of biofuel production.
An international study investigating the carbon sink capacity of northern terrestrial ecosystems discovered that the duration of the net carbon uptake period (CUP) has on average decreased due to warmer autumn temperatures.
Global warming and other human-caused ecological changes are outpacing the ability of species to adapt, resulting in greater threats of disease, reduced diversity in plant and animal communities, and an overall loss of natural heritage, according to research presented at a University of California, Los Angeles (UCLA) summit and published in the peer-reviewed journal Molecular Ecology.
Carbon emissions from human activities are not just heating up the globe, they are changing the ocean¡¦s chemistry. This could soon be fatal to coral reefs, which are havens for marine biodiversity and underpin the economies of many coastal communities. Scientists from the Carnegie Institution¡¦s Department of Global Ecology have calculated that if current carbon dioxide emission trends continue, by mid-century 98% of present-day reef habitats will be bathed in water too acidic for reef growth. Among the first victims will be Australia¡¦s Great Barrier Reef, the world¡¦s largest organic structure.
The largest living structures on Earth and the millions of livelihoods which depend upon them are at risk, the most definitive review yet of the impact of rising carbon emissions on coral reefs has concluded
A quick and cool way to help combat climate change is now available at www.conservation.org/carboncalculator.
Researchers at the University of Illinois have developed a new model of global carbon and nitrogen cycling that will fundamentally transform the understanding of how plants and soils interact with a changing atmosphere and climate.
The role of Earth Observation satellites in combating climate change is being highlighted at the United Nations climate change conference where thousands of delegates from more than 180 countries are gathered to begin negotiations of an international emissions-cutting agreement to succeed the Kyoto Protocol, whose first commitment period ends in 2012.
Levels of a climate cooling gas will change as carbon dioxide increases, affecting food webs along the way, said Dr Michael Steinke at a Science Media Centre press briefing today.
Climate change will affect national parks, forest reserves and other protected areas around the world, in some cases altering conditions so severely that the resulting environments will be virtually new to the planet, according to a study presented at the U.N. climate change talks in Bali, Indonesia.
