  • The global warming potential of wheat

    Nitrous oxide concentrations in the earth’s atmosphere have increased since the industrial revolution. This is of concern as nitrous oxide contributes to global warming and the destruction of the ozone layer. It has 310 times the global warming potential of carbon dioxide and a lifespan of 120 years. Emissions from agricultural soils are considered to account for 70 to 80 percent of the increase. ...

  • Global warming to affect metabolism of mosquitoes

    The impact of global warming on the metabolism of mosquitoes could further complicate predictions of how climate change will affect malaria, according to scientists. Scientists have for the first time estimated how warmer climate will affect the metabolism of cold-blooded animals, such as mosquitoes, on a global scale. Such animals depend on outside temperature to regulate their body's ...

  • Are sunspots prime suspects in global warming?

    (AXcess News) - It's a modern-day climate scuffle William Herschel would recognize. He should. He helped trigger it. In 1801, the eminent British astron­­omer reported that when sunspots dotted the sun's surface, grain prices fell. When sunspots waned, prices rose. He suggested that shifts in grain prices were a stand-in for shifts in climate. Large numbers of sunspots led to a ...

  • Global warming threatens colder climate for Europe

    Scientists have yet again warned that weakening ocean circulation in the North Atlantic could deliver a climate paradox − a colder Europe as a consequence of global warming. A study published in Nature Climate Change found that as sea ice off Iceland and Greenland retreats, the flow of cold, dense water to the bottom of the North Atlantic ocean could be reduced, ...

  • Brazilian companies announce global warming game plan

    The Brazil Greenhouse Gas Protocol Program was launched on Tuesday and its 12 founding corporate members have voluntarily agreed to report their global-warming emissions. “The program provides options for sound measurement and allows members to take action to reduce their GHG emissions,” said Thelma Krug, secretary of climate change, Brazil Environment Ministry, at the launch event here in the ...

  • Global warming brings more snow to Antarctica

    Although it sounds paradoxical, rising temperatures might result in more snowfall in Antarctica. Each degree of regional warming could increase snowfall on the ice continent by about 5 percent, an international team of scientists led by the Potsdam Institute for Climate Impact Research now quantified. Published in the journal Nature Climate Change, their work builds on high-quality ice-core data ...

  • Why Diatoms could help stop global warming?

    The shells of diatoms are so heavy that when they die in the oceans they typically sink to watery graves on the seafloor, taking carbon out of the surface waters and locking it into sediments below. Scientists have reported the discovery of whole subsets of genes and proteins that govern how one species of diatom builds its shell. For oceanographers, the work might one day help them understand ...

  • Honeywell`s Low-Global-Warming Potential Performance Fluid Approved By U.S. Environmental Protection Agency For Use As Aerosol Solvent

     Honeywell (NYSE: HON) announced today the U.S. Environmental Protection Agency has approved Honeywell's new low-global-warming-potential Solstice™ Performance Fluid (PF) for use in aerosol solvent applications. "The availability of Solstice PF as an aerosol solvent, and Honeywell's low-global-warming-potential Solstice Propellant, means that manufacturers and marketers of aerosol ...

  • IMF urges action soon on global warming

    Climate change is likely to have an adverse impact on economic growth over the long run and will set back efforts to help the poorest countries, unless the international community takes decisive action, IMF Deputy Managing Director Takatoshi Kato told the UN Conference on Climate Change in Bali, Indonesia. 'Climate change is perhaps the largest collective action problem that the world faces,' ...


  • US lawmakers urged to lead global warming battle

    The head of the United Nations scientific climate panel spoke with U.S. lawmakers Wednesday, encouraging them lead the world in cooling the overheated planet. 'We really don't have a moment to lose,' said Rajendra Pachauri, chair of the UN Intergovernmental Panel on Climate Change, IPCC.  The massive reductions in greenhouse gas emissions needed to avoid serious disruptions to Earth's climate ...

  • UN: Global Warming Will Change the Lives of Millions

    TROMSO, Norway (ENS) - As the Earth warms, hundreds of millions of people worldwide will be affected by melting snow covers, ice and glaciers, according to a new United Nations report issued to mark World Environment Day, observed on June 5 each year. The availability of water supplies for both drinking and agriculture will also be impacted, while rising sea levels will affect ...

  • Preparing for global warming`s health crisis

    Hurricanes pound the Gulf Coast with unrelenting force. Floods deluge the Midwest. Wildfires rage out of control in California and Florida. A 'red tide' of algae blooms off the West Coast, endangering marine and coastal wildlife. Dengue fever spikes in Mexico and looms over the United States.  No one can say with certainty that any single one of these events is due to global climate change. But ...

  • Impacts of global warming will impoverish oceans – New Report

    Ocean ecosystems and fisheries could be at risk of collapse under the combined assault of global warming and increasingly acid seas. This bleak image of impoverished and increasingly hostile oceans emerges not from any one new study of human impact on the 70 per cent of the ...

  • Pennsylvania Assembly passes first global warming law

    Global warming legislation will be enacted for the first time in Pennsylvania when Governor Ed Rendell signs the Pennsylvania Climate Change Act as he is expected to do. The measure was overwhelmingly approved today by both houses of the Pennsylvania General Assembly. A coal-rich state, Pennsylvania emits one percent of the world’s greenhouse gases responsible for global warming, more than the ...

  • Stabilizing global warming - we have the technology

    The bad news according to Princeton University's Carbon Mitigation Initiative, carbon emissions from fossil fuel burning are projected to double in the next 50 years keeping the world on course to more than triple the atmospheres carbon dioxide (CO2) concentration from its pre-industrial level. The good news is we already have the technology we need to take the world off the path toward dramatic ...

  • Will it really cost US$45tr to combat global warming?

    A UN-network of scientists concluded last year that emissions have to be cut by at least half by 2050 to avoid an increase in world temperatures of between 3.6 and 4.2 degrees above pre-18th century levels. 'Meeting this target of 50 percent cut in emissions represents a formidable challenge, and we would require immediate policy action and technological transition on an unprecedented scale,' IEA ...

  • IPCC report more certain about global warming

    Development experts and scientists have reacted cautiously to leaked versions of the first part of the fifth assessment report of the Intergovernmental Panel on climate change (IPCC), which deals with the physical science of climate change and will be released in Stockholm, Sweden, on Monday (30 September). ...

  • Will it really cost $45 trillion to combat global warming?

    Last week the Paris-based International Energy Agency released a study suggesting the world must invest $45 trillion in coming decades to cut greenhouse gas emissions by at least half by 2050. This would be needed to finance some 1,400 nuclear power plants, the development of carbon sequestration technology and the expansion of wind power. Not everyone agrees the price tag would be so costly, or ...
