• Climate Change to Make Wildfires in Oregon's Blue Mountains More Frequent, Severe

    Under a warming climate, wildfires in Oregon’s southern Blue Mountains will become more frequent, more extensive and more severe, a new study finds. The researchers urge forest managers to continue to reduce fuel continuity through accelerated rates of thinning and prescribed burning to help reduce the extent and severity of future fires.

  • Extreme Conditions Created “Perfect Storm” for Catastrophic Aussie Fires

    An Australian fire expert says her analyses of bushlands around Sydney in the final months of 2019 indicated that the landscape was primed for these catastrophic fires—but it was series of other conditions, all happening concurrently, that ultimately led to the disaster. The recent drought conditions were key to creating the “perfect storm” that allowed all other pre-conditions to occur concurrently.

  • Australia’s Fires: The Worst Is Yet to Come

    “Human-caused climate change is most certainly an important contributing factor to the recent fire season in Australia,” says an expert. “What is perhaps most concerning, is that while this year’s fire season, just now underway, appears to be unprecedented, forecasts suggest it will be dwarfed by future conditions.”

  • International Effort to Improve Urban Resilience

    Extreme climate events are severely affecting communities in the U.S. and around the world. The examples are plenty. Bushfires in Australia, wildfires in California, flooding on both U.S. coasts and inland, and much more. In the face of extreme climate events, experts explore developing nature-based solutions.

  • Climate Change Intensified Hurricane Florence’s Precipitation and Size

    found that Hurricane Florence produced more extreme rainfall and was spatially larger due to human-induced climate change. Previous research has suggested that human influences such as emission of greenhouse gasses that alter climate does affect precipitation in extreme storms. The research in this study, however, is a first to use a “forecast attribution” framework that enables scientists to investigate the effect of climate change on individual storm events days in advance.

  • Climate Changes Detected in Daily Weather

    Climate researchers can now detect the fingerprint of global warming in daily weather observations at the global scale. They are thus amending a long-established paradigm: weather is not climate –but climate change can now be detected in daily weather.

  • 6. Climate Change’s Threat to National Security

    The past year saw more military and intelligence services of more governments give expression to their recognition of the serious threat the consequences of climate change pose to national security and international stability.

  • Comparing Floodplain Protection Today to Predicted Future Flood Losses

    A new study seeks to answer an important question related to flooding in the United States – pay now to protect undeveloped areas that are likely to flood in the future or allow developments to go ahead and pay for damage when it occurs.

  • In Win for Harvey Victims, Federal Judge Finds Government Liable for Reservoir Flooding

    During Hurricane Harvey, thousands of properties behind two federally owned reservoirs flooded. On Tuesday, the United States Court of Federal Claims ruled that the government was liable for the flooding and that property owners are eligible for damages.

  • The Earth Needs Multiple Methods for Removing CO2 from the Air to Avert Worst of Climate Change

    Concentrations of carbon dioxide in the atmosphere are higher than at any time in human history, and nine of the warmest years have occurred since 2005. “Avoiding catastrophic impacts on our coastal infrastructure, biodiversity, food, energy and water resources will require more. In particular, many climate researchers like myself believe government needs to advance technology that will actually suck carbon dioxide out of the air and put it away for very long periods,” David Goldberg writes.

  • Harnessing Nature’s Defenses against Tsunamis

    As sea levels rise and adverse weather events become more common, vulnerable coastal communities are at increasing risk of devastation from storm surges and tsunamis. The death toll from tsunamis, at 260,000 during the past century, was higher than that from any other natural hazard. Researchers say that biodiversity can help in protecting coastal communities.

  • Greenland’s Ice Loss “Faster Than Expected”

    Greenland is losing ice faster than in the 1990s and is tracking the Intergovernmental Panel on Climate Change’s high-end climate scenario. As a result, 40 million more people will be exposed to coastal flooding by 2100.

  • The Challenges Facing Fisheries Climate Risk Insurance

    The world’s first “Fisheries Index Insurance” scheme, launched by an international consortium in July, is a sovereign-level instrument designed to protect Caribbean fishing communities from extreme weather events which may become more frequent and intense due to climate change. But insurance schemes with the potential to improve the resilience of global fisheries face a host of future challenges, researchers say.

  • Scientists Warn of Weather Extremes as “New Normal”

    Scientists warned that faster and stronger climate change is threatening the Earth and humankind as extreme weather has become the “new normal,” according to a report presented to UN climate chief. The report found that climate change is forcing people to reconsider the notion of an extreme event. What was once considered unlikely or rare – is becoming part of the “new normal.”

  • Flash Flooding Is a Serious Threat in the U.K. – Here’s How Scientists Are Tackling Its Prediction

    Surface water flooding is what happens in built-up areas when heavy rainfall has nowhere to go. Unable to enter a watercourse or drainage system, the water instead flows over the ground causing flash flooding. Unlike river and coastal flooding, which can be widespread, surface water flooding presents unique challenges because it’s difficult to predict the location, timing and impact of what are typically localized events. As the climate changes and urban populations grow, the number of people at risk of surface water flooding increases.
