• Aerosols May Have High Impact On Rainfall, Climate Change

    Aerosols may have a greater impact on patterns of Australian rainfall and future climate change than previously thought, according to leading atmospheric scientist, CSIRO's Dr Leon Rotstayn. "We have identified that the extensive pollution haze emanating from Asia may be re-shaping rainfall patterns in northern Australia but we wonder what impact natural and human-generated aerosols are having across the rest of the country," Dr Rotstayn said. >> Read the Full Article
  • Western states' climate laws: the cost of inaction

    If Western states don't substantially reduce greenhouse gas emissions, they could face billions of dollars in health care and other related costs by 2020, according to reports by economists for the University of Oregon's Climate Leadership Initiative's Program on Climate Economics. Washington, Oregon and New Mexico will probably face associated annual costs of $3.8 billion, $3.3 billion and $3.2 billion by 2020, respectively, if they don't rein in greenhouse gas emissions, logging and other factors that drive climate change, according to reports released Monday. >> Read the Full Article
  • Fires and climate change prompt soul-searching in Australia

    Scientists say that Australia can expect more of the scorching conditions that fanned the firestorms that killed at least 181 people this month, prompting a nationwide debate about how to prepare for a hotter, more fire-prone future. As investigators pick through the tangled wreckage left by Australia's deadliest wildfires, which flattened townships and destroyed more than 1,000 homes starting Feb. 7, a wide-ranging discussion has begun about the way the country handles wildfires - from greenhouse-gas emissions standards to planning codes to an emergency protocol that encourages people to stay and defend their properties. >> Read the Full Article
  • North Atlantic is world's 'climate superpower'

    IF EVER there was a superpower of the oceans, the North Atlantic, with its ability to control global weather systems, is it. The bad news is that this region also happens to be especially sensitive to the effects of climate change, so what is happening there could affect the world. The planet's climate goes through periodic convulsions that affect every region simultaneously. The most recent were in the early 1940s and mid-1970s. The latter coincided with the start of more frequent El Niño events in the Pacific and a strong global warming trend. >> Read the Full Article
  • EPA official: we may need to stimulate volcanoes to slow down global warming

    We've heard from far-out talk in the past about trying various ways to slow down global warming, including trying to set off volcanic eruptions. Yes, it sounds like vintage Ray Bradbury. But now the idea is getting blessed by a top U.S. Environmental Protection Agency scientist. According to Inside EPA Weekly Report, the presentation was given earlier this month: A high-ranking EPA official lays out in a new analytical paper key technological and other mitigation options the United States and other countries should pursue to delay the impacts of climate change in an effort to allow time to develop other, more advanced technologies to reduce greenhouse gas (GHG) emissions. >> Read the Full Article
  • Climate change delaying gray whale vacations, scientists say

    Out in the deep waters of Monterey Bay, gray whales will be swimming home later this month after a brief winter vacation in Baja California. Whale watchers and marine scientists say these whales have been delaying their southern sojourns and point to climate change as the culprit. >> Read the Full Article
  • CO2 hits new peaks, no sign global crisis causing dip

    OSLO (Reuters) - Atmospheric levels of the main greenhouse gas are hitting new highs, with no sign yet that the world economic downturn is curbing industrial emissions, a leading scientist said on Thursday. "The rise is in line with the long-term trend," Kim Holmen, research director at the Norwegian Polar Institute, said of the measurements taken by a Stockholm University project on the Arctic archipelago of Svalbard off north Norway. >> Read the Full Article
  • Why Global Warming May Be Fueling Australia's Fires

    The raging infernos that have left more than 160 people dead in southern Australia burned with such speed that they resembled less a wildfire than a massive aerial bombing. Many victims caught in the blazes had no time to escape; their houses disintegrated around them, and they burned to death. >> Read the Full Article
  • Merged climate, pollution fight seen saving cash

    Merging separate fights against air pollution and climate change could save cash and encourage developing nations such as China to do more to curb global warming, researchers said on Wednesday. "There are big gains to be made" from a combined policy, said Petter Tollefsen, a researcher at the Center for International Climate and Environmental Research, Oslo (CICERO). >> Read the Full Article
  • $400 billion: The price of our future

    Just $400 billion - 0.8% of global GDP. That's how much money one of the world's leading economists says governments around the world need to put towards "green" policies that will ensure global finances and the global environment prosper in the 21st century. There's a catch, and it's a big one: the money needs to be set aside by this summer and spent by mid-2010. >> Read the Full Article
