• Previously Unrecognized Tsunami Hazard to Coastal Cities Identified

    A new study found overlooked tsunami hazards related to undersea, near-shore strike-slip faults, especially for coastal cities adjacent to faults that traverse inland bays. Several areas around the world may fall into this category, including the San Francisco Bay Area, Izmit Bay in Turkey and the Gulf of Aqaba in Egypt.

  • Solar Geoengineering May Alleviate Impacts of Global Warming on Crops

    Solar geoengineering — putting aerosols into the atmosphere to reflect sunlight and reduce global warming — is not a fix-all for climate change but it could be one of several tools to manage climate risks. A growing body of research has explored the ability of solar geoengineering to reduce physical climate changes. But much less is known about how solar geoengineering could affect the ecosystem and, particularly, agriculture.

  • “Viable but Narrow” Pathway to Zero Carbon Emissions by 2050: IEA

    The world has a viable pathway to building a global energy sector with net-zero emissions in 2050, but it is narrow and requires an unprecedented transformation of how energy is produced, transported and used globally, the International Energy Agency said in a landmark special report released Tuesday.

  • A Dangerous Fire Season Looms as the Drought-Stricken Western U.S. Heads for a Water Crisis

    Just about every indicator of drought is flashing red across the western U.S. after a dry winter and warm early spring. The snowpack is at less than half of normal in much of the region. Reservoirs are being drawn down, river levels are dropping and soils are drying out. It’s only May, and states are already considering water use restrictions to make the supply last longer.

  • Seeking Inclusive Strategies to Help Coastal Communities Adjust, Plan for Sea-Level Rise

    Recurring flood damage to homes and powerful storms that threaten infrastructure are realities facing many coastal North Carolina communities. However, for three predominately African-American, rural communities near the coast, NC State researchers documented additional injustices that threaten the communities’ ability to adapt to a changing climate.

  • Antarctica Remains the Wild Card for Sea-Level Rise Estimates

    Estimates show that limiting global warming to 1.5 degrees C above pre-industrial temperatures would cut projected 21st century sea-level rise from land ice in half, relative to currently pledged emissions reductions.

  • Coral Reefs Prevent More than $5.3 Billion in Potential Flood Damage for U.S. Property Owners

    Coral reefs provide many services to coastal communities, including critical protection from flood damage. A new study reveals how valuable coral reefs are in protecting people, structures, and economic activity in the United States from coastal flooding during storms.

  • The New U.S. Climate Normals Are Here

    Every 10 years, NOAA releases an analysis of U.S. weather of the past three decades that calculates average values for temperature, rainfall and other conditions. That time has come again. Known as the U.S. Climate Normals, these 30-year averages — now spanning 1991-2020 — represent the new “normals” of our changing climate.

  • Antarctic Ice-Sheet Melting to Lift Sea Level Higher Than Thought: Study

    Global sea-level rise associated with the possible collapse of the West Antarctic Ice Sheet has been significantly underestimated in previous studies, meaning the sea level in a warming world will be greater than anticipated, according to a new study. New calculations show the rise due to warming would be 30 percent above forecasts.

  • California's Wildfire Season Has Lengthened, and Its Peak Is Now Earlier in the Year

    California’s wildfire problem, fueled by a concurrence of climate change and a heightened risk of human-caused ignitions in once uninhabited areas, has been getting worse with each passing year of the 21st century.Researchers have found that the annual burn season has lengthened in the past two decades and that the yearly peak has shifted from August to July.

  • Interstate Water Wars Are Heating Up Along with the Climate

    Interstate water disputes are as American as apple pie. States often think a neighboring state is using more than its fair share from a river, lake or aquifer that crosses borders. Climate stresses are raising the stakes.

  • U.S. Power Sector is Halfway to Zero Carbon Emissions

    Concerns about climate change are driving a growing number of states, utilities, and corporations to set the goal of zeroing out power-sector carbon emissions. To date 17 states plus Washington, D.C. and Puerto Rico have adopted laws or executive orders to achieve 100% carbon-free electricity in the next couple of decades. Additionally, 46 U.S. utilities have pledged to go carbon free no later than 2050. Altogether, these goals cover about half of the U.S. population and economy.

  • The U.S. Water and Wastewater Crisis – How Many Wake-up Calls Are Enough?

    In February, much of Texas plunged into darkness when the state’s electricity grid failed due to extreme cold weather conditions. What started as a foreseeable blackout quickly became a life-threatening calamity. “This catastrophe illustrates what happens when aging and inadequate infrastructure is hit by extreme rain or snow—an increasingly regular occurrence due to climate change,” Lucía Falcón Palomar, Obinna Maduka, and JoAnn Kamuf Ward write. “And, the matter extends well beyond Texas. It is easy to forget that, within U.S. borders, communities have long endured the conditions seen in Texas in February.”

  • Could South African Mine Wastes Provide a Feasible Storage Method for Millions of Tons of CO2?

    Mine sites are literally well-oiled machines, and it is easy to witness both the pros and cons that sites have on our society. However, hidden in plain sight among the hectic operations is perhaps the biggest untapped source of material that could help us in our ongoing battle with climate change. A material often perceived as having a negative effect on the environment – mine wastes known as tailings.

  • How Microorganisms Can Help Us Get to Net Negative Emissions

    To reduce our reliance on fossil fuels and reduce greenhouse gas emissions, society has increasingly tried turning to plants to make the everyday products we need. But what if plants could be removed from the picture, eliminating the need for water, fertilizer, and land? What if microbes could instead be harnessed to make fuels and other products? And what if these microbes could grow on carbon dioxide, thus simultaneously producing valuable goods while also removing a greenhouse gas from the atmosphere, all in one reactor?
