• Extreme Coastal Flooding in the U.S. Expected to Rise

    Extreme flooding events in some U.S. coastal areas could double every five years if sea levels continue to rise as expected, a new study says. Today’s “once-in-a-lifetime” extreme water levels — which are currently reached once every fifty years — may be exceeded daily along most of the U.S. coastline. Associated coastal hazards, such as beach and cliff erosion, will likely accelerate in concert with the increased risk of flooding, suggest the authors.

  • Climate-Driven Megadrought Is Emerging in Western U.S.: Study

    With the western United States and northern Mexico suffering an ever-lengthening string of dry years starting in 2000, scientists have been warning for some time that climate change may be pushing the region toward an extreme long-term drought worse than any in recorded history. A new study says the time has arrived: a megadrought as bad or worse than anything even from known prehistory is very likely in progress, and warming climate is playing a key role.

  • Coronavirus Shows We Are Not at All Prepared for the Security threat of climate change

    How might a single threat, even one deemed unlikely, spiral into an evolving global crisis which challenges the foundations of global security, economic stability and democratic governance, all in the matter of a few weeks? My research on threats to national security, governance and geopolitics has focused on exactly this question, albeit with a focus on the disruptive potential of climate change, rather than a novel coronavirus. At this stage in the COVID-19 situation, there are three primary lessons for a climate-changing future: the immense challenge of global coordination during a crisis, the potential for authoritarian emergency responses, and the spiraling danger of compounding shocks.

  • Wind Energy Expansion Would Have $27 Billion Economic Impact

    Wind, which generates less greenhouse gas emission than burning fossil fuels, is making up an increasing share of the energy production portfolio in the United States. But wind is not as efficient as coal or natural gas, causing some concern about its economic impact. A new study that models increased wind production in 10 states shows significant economic impact in those states, as well as billions of dollars spread over the rest of the country.

  • New Website Will Help Steer the U.S. Away from Fossil Fuels

    A new website, Model Laws for Deep Decarbonization in the United States, was launched on Tuesday to help accelerate a sustainable U.S. transition to net-zero greenhouse gas emissions. It will provide policy makers at the federal, state and local levels with the legal tools needed to transition away from fossil fuels.

  • Floating Wind Turbines on the Rise

    Over 26,000 megawatts (MW) of planned offshore wind capacity exists in the offshore wind development pipeline. Rapidly falling technology costs for offshore wind, including floating offshore wind technology, have aided the growth of this pipeline and promise to help wind become a significant part of the power mix in coastal communities.

  • Climate-Related Disasters Increase Risks of Conflict in Vulnerable Countries

    The risk for violent clashes increases after weather extremes such as droughts or floods hit people in vulnerable countries, an international team of scientists finds. Vulnerable countries are characterized by a large population, political exclusion of particular ethnic groups, and low development. The study combines global statistical analysis, observation data and regional case study assessments to yield new evidence for policymakers.

  • Uncertain Climate Future May Disrupt Energy Systems

    Extreme weather events – such as severe drought, storms, and heat waves – have been forecast to become more commonplace and are already starting to occur. What has been less studied is the impact on energy systems and how communities can avoid costly disruptions, such as partial or total blackouts.

  • Australia: Grim Story of Heat, Drought and Fire

    Record hot weather, drought and a devastating bushfire season in 2019 damaged our environment and natural resources on an unprecedented scale, according to the annual Australia’s Environment Report. “Last year was just another step down on the continuing descent into an ever more dismal future - unless we finally take serious action,” said the lead author of the report.

  • Reducing U.S. Fossil-Fuel Dependence: Left, Right Agree on Goal, Differ on Means

    Both sides of the political spectrum recognize a need to reduce American dependence on carbon-based energy sources, but how the nation does so remains a divisive issue, a new study found.

  • Impact of a Second Dust Bowl Would Be Felt Worldwide

    The American Dust Bowl of the 1930s - captured by the novels of John Steinbeck - was an environmental and socio-economic disaster that worsened the Great Depression. The Dust Bowl was an extreme event. But due to climate change, massive crop failures are more likely to happen again in the future. A catastrophic shock to U.S. agriculture would deplete reserves, including those of other countries.

  • Coal Developers Risk $600 Billion As Renewables Outcompete Worldwide

    Coal developers risk wasting more than $600 billion because it is already cheaper to generate electricity from new renewables than from new coal plants in all major markets, the financial think tank Carbon Tracker warns in a new report. The report also finds that over 60 percent of global coal power plants are generating electricity at higher cost than it could be produced by building new renewables. By 2030 at the latest it will be cheaper to build new wind or solar capacity than continue operating coal in all markets.

  • Earth Just Had Its 2nd-Hottest February on Record

    The planet sweated it out again last month, as February 2020 ranked as the second-hottest February in the 141-year global climate record. In addition, meteorological winter hardly made an appearance in large parts of the Northern Hemisphere, as both Europe and Asia recorded their warmest winters ever.

  • Australia’s Bushfires “Made 30% More Likely by Climate Change”

    The World Weather Attribution (WWA) initiative has released the first analysis of the role climate change played in the 2019-2020 bushfire season in South-Eastern Australia, which showed that the risk of intense fire weather has increased by 30 percent since 1900 as a result of anthropogenic climate change.

  • We Climate Scientists Won’t Know Exactly How the Crisis Will Unfold Until it’s Too Late

    When we hold on to things for too long, change can come about abruptly and even catastrophically. While this will ring true for many from personal experience, similar things can happen at large scales as well. Indeed, the history of Earth’s climate and ecosystems is punctuated by frequent large-scale disruptive events.
