• Population increases, climate change will cause future U.S. water shortages

    Climate change plus population growth are setting the stage for water shortages in parts of the U.S. long before the end of the century, according to a new study. Even efforts to use water more efficiently in municipal and industrial sectors won’t be enough to stave off shortages, say the authors of the new study. The results suggest that reductions in agricultural water use will probably play the biggest role in limiting future water shortages.

  • “It eats everything” – the new breed of wildfire that’s impossible to predict

    Climate change and negligent forest management are causing higher-intensity, faster-moving fires that can generate enough energy to evolve into erratic firestorms, known as pyroCbs, in the face of which first responders can do little.

  • Climate change increases potential for conflict, violence

    Images of extensive flooding or fire-ravaged communities help us see how climate change is accelerating the severity of natural disasters. The devastation is obvious, but what is not as clear is the indirect effect of these disasters, or more generally of rapid climate change, on violence and aggression.

  • And now, land may be sinking

    In the coming decades, cities and towns up and down the eastern seaboard will have to come to terms with the impact of rising sea level due to climate change. A new study, however, is suggesting that rising sea levels may be only part of the picture — because the land along the coast is also sinking.

  • Rising seas disrupt local economies

    Impacts from climate change are not always easy to see. But for many local businesses in coastal communities across the United States, the evidence is right outside their doors – or in their parking lots. High-tide flooding resulting from climate change is already disrupting the economy of Annapolis, Maryland. As sea levels rise, the impacts are expected to get worse for coastal communities.

  • Keeping the lights on during and after a disaster

    The threat of an inevitable earthquake is the uncomfortable truth we all face in the Cascadia Subduction Zone, which stretches from Alaska to California. Because the last major earthquake in the area was in the 1700s, our infrastructure developed without an appreciation and understanding of earthquake resilience. That means the next major earthquake will likely devastate our buildings, roads, bridges, and utility providers, posing immediate risks for the health and safety of those who live in the region. And later, there will be long-term economic aftershocks.

  • In one generation, climate of North American cities will shift hundreds of miles

    In one generation, the climate experienced in many North American cities is projected to change to that of locations hundreds of miles away—or to a new climate unlike any found in North America today. New web application helps visualize climate changes in 540 North American cities.

  • 2018 fourth warmest year in continued warming trend

    Earth’s global surface temperatures in 2018 were the fourth warmest since 1880, according to independent analyses by NASA and the National Oceanic and Atmospheric Administration (NOAA). Global temperatures in 2018 were 1.5 degrees Fahrenheit (0.83 degrees Celsius) warmer than the 1951 to 1980 mean. Globally, 2018’s temperatures rank behind those of 2016, 2017 and 2015. The past five years are, collectively, the warmest years in the modern record.

  • Lawmakers tell Pentagon to redo climate change report

    Earlier this month, the Pentagon, in compliance with a congressional mandate, released a landmark report which identified the 79 American military installations most vulnerable to the “effects of a changing climate.” Several Democrats on the House Armed Services Committee welcomed the report – but at the same time harshly criticized it for failing to include details requested by Congress, among them the estimates by each of the armed services of the cost of protecting or replacing the ten most vulnerable military bases.

  • Rising seas: to keep humans safe, let nature shape the coast

    Even under the most conservative climate change scenarios, sea levels 30cm higher than at present seem all but certain on much of the U.K.’s coast by the end of this century. Depending on emission scenarios, sea levels one meter higher than at present by 2100 are also plausible. The knee-jerk reaction to sea level rise has traditionally been to maintain the shoreline’s position at all cost, by building new flood defense structures or upgrading old ones, but this traditional approach of “grey” engineered sea defenses locks society into ever increasing costs of replacement and maintenance. The alternatives are “nature-based solutions” to coastal flooding and erosion, which work with natural processes to reduce flood risk and incorporate ecosystems into flood defense.

  • Diffusing the methane bomb

    The Arctic is warming twice as fast as the rest of the planet, causing the carbon containing permafrost that has been frozen for tens or hundreds of thousands of years to thaw and release methane into the atmosphere, thereby contributing to global warming. The findings of a study that included researchers from IIASA, however, suggest that it is still possible to neutralize this threat.

  • Seas may be rising faster than thought

    A new Tulane University study questions the reliability of how sea-level rise in low-lying coastal areas such as southern Louisiana is measured and suggests that the current method underestimates the severity of the problem.

  • Causal link established between climate, conflict, and migration

    Researchers have established a causal link between climate, conflict, and migration for the first time, something which has been widely suggested in the media but for which scientific evidence is scarce. There are numerous examples in recent decades in which climatic conditions have been blamed for creating political unrest, civil war, and subsequently, waves of migration. One major example is the ongoing conflict in Syria, which began in 2011. Many coastal Mediterranean countries in Europe are also inundated with refugees arriving by sea fleeing conflict in Africa.

  • Climate change tipping point may be coming sooner than we think

    Global carbon emissions reached a record high in 2018, rising by an estimated 3.4 percent in the U.S. alone. This trend is making scientists, government officials, and industry leaders more anxious than ever about the future of our planet. While it’s known that extreme weather events can affect the year-to-year variability in carbon uptake, but a new study is the first to actually quantify the effects through the 21st century and demonstrates that wetter-than-normal years do not compensate for losses in carbon uptake during dryer-than-normal years, caused by events such as droughts or heatwaves.

  • New decision-making tool for oil spill clean-up

    Engineers have created an interactive decision tree aimed at finding the best solution for specific oil spill scenarios. Numerous chemical dispersant technologies are available to address different types of oil spills and countless variables and external conditions can play into the effectiveness of any given dispersant. The decision-making tool helps bridge this gap to determine how a dispersant technology will perform under different spill scenarios.
