• Adaptation to climate risks: Political affiliation matters

    A new study reveals that those who affiliate with the Democratic Party have different views than those who vote Republican on the following issues: the likelihood of floods occurring, adopting protection measures, and expectations of disaster relief from the government.

  • 2015 surpassed 2014 as the warmest year since at least the mid-to-late nineteenth century

    A new State of the Climate report confirmed that 2015 surpassed 2014 as the warmest year since at least the mid-to-late nineteenth century. Last year’s record heat resulted from the combined influence of long-term global warming and one of the strongest El Niño events the globe has experienced since at least 1950. The report found that most indicators of climate change continued to reflect trends consistent with a warming planet. Several markers such as land and ocean temperatures, sea levels, and greenhouse gases broke records set just one year prior.

  • Climate risk and the fossil fuel industry

    Burning coal, oil, and natural gas is responsible for two-thirds of the world’s greenhouse gas emissions. Yet these same fuels are also the economic mainstay of resource-rich countries and the world’s largest companies. According to a new study, this means that climate-change relief actions represent danger for the fossil fuel business.

  • Electric grid vulnerabilities in extreme weather areas

    Climate and energy scientists at the DoE’s Oak Ridge National Laboratory have developed a new method to pinpoint which electrical service areas will be most vulnerable as populations grow and temperatures rise. The scientists’ integrated approach – combining ORNL’s unique infrastructure and population datasets with high-resolution climate simulations run on the lab’s Titan supercomputer —  identifies substations at the neighborhood level and determines their ability to handle additional demand based on predicted changes in climate and population.

  • Sea-level rise threatens many coastal U.S. military bases

    The U.S. Armed Forces depend on safe and functional bases to protect the U.S. national security. Sea levels are rising as global warming heats up the planet, and many military bases along the U.S. East Coast and Gulf of Mexico are at risk of permanently losing land to the ocean in the decades ahead. As the seas rise, high tides will reach farther inland. Tidal flooding will become more frequent and extensive. When hurricanes strike, deeper and more extensive storm surge flooding will occur. The United States must thus prepare for the growing exposure of its military bases to sea level rise.

  • Warmings greater than 1.5 °C inevitable owing to current atmospheric greenhouse concentrations

    Current levels of atmospheric greenhouse gas concentrations already commit the planet to air temperatures over many land regions being eventually warmed by greater than 1.5°C, according to new research. The results of the new study have implications for international discussions of what constitutes safe global temperature thresholds, such as 1.5°C or 2°C of warming since pre-industrial times. The expected extra warming over land will influence how we need to design some cities. It could also impact on the responses of trees and plants, including crops.

  • Climate disasters increase risk of armed conflict in multi-ethnic countries

    Climate disasters like heat-waves or droughts enhance the risk of armed conflicts in countries with high ethnic diversity, scientists found. Each conflict is certainly the result of a complex and specific mix of factors, but it turns out that the outbreak of violence in ethnically fractionalized countries is often linked to natural disasters that may fuel smoldering social tensions.

  • New research predicts a doubling of coastal erosion by mid-century in Hawai’i

    Chronic erosion dominates the sandy beaches of Hawai’i, causing beach loss as it damages homes, infrastructure, and critical habitat. Researchers have long understood that global sea level rise will affect the rate of coastal erosion. Newresearch team developed a simple model to assess future erosion hazards under higher sea levels.

  • Cape Cod susceptible to potential effects of sea-level rise

    Cape Cod is vulnerable to rising water tables and, in some areas, groundwater inundation as a result of rising sea levels, according to a new U.S. Geological Survey study (USGS). Groundwater inundation occurs when the water table reaches or exceeds land surface. The challenges associated with the issue are likely to become more prevalent as seas rise. Depending on the severity, it may make areas unsuitable for residential and commercial development.

  • Managing the endangered Rio Grande River across the U.S.-Mexico border

    The Rio Grande (called Rio Bravo in Mexico) is the lifeline to an expansive desert in the southwest United States and northern Mexico. From Colorado to the Gulf of Mexico, over 3,000 km, people depend on the river to quench their thirst and irrigate their crops. Yet as the river flows from the United States, it brings with it conflicts and challenges. The water level in the river is declining as use exceeds supply. Water demand is rising as the population in the region grows, and corresponding economic growth drives continued development. Moreover, climate change is expected to lower water levels even further, exacerbating the problems.

  • Breaking records: The first six months of 2016 the warmest half-year on record

    Two key climate change indicators — global surface temperatures and Arctic sea ice extent — have broken numerous records through the first half of 2016. While these two key climate indicators have broken records in 2016, NASA scientists said it is more significant that global temperature and Arctic sea ice are continuing their decades-long trends of change. Both trends are ultimately driven by rising concentrations of heat-trapping carbon dioxide and other greenhouse gases in the atmosphere.

  • What do climate tipping points mean for society

    The phrase “tipping point” passed its own tipping point and caught fire after author Malcolm Gladwell’s so-named 2000 book. It is now frequently used in discussions about climate change, but what are “climate tipping points”? And what do they mean for society and the economy? In a new study, scientists tackle the terminology and outline a strategy for investigating the consequences of climate tipping points. The authors recommend using the phrase “climatic tipping elements” to describe portions of the climate system that may be abruptly committed to major shifts as a result of the changing climate.

  • Assessing climate change risks to U.K.

    Climate change is happening now. Globally, 14 of the 15 hottest years on record have occurred since 2000. The impacts of climate change are already being felt in the United Kingdom, and urgent action is required to address climate-related risks, the Committee on Climate Change’s (CCC)’s Adaptation Sub-Committee (ASC) said the other day.

  • 100s of deaths in two cities in 2003 heatwave due to man-made climate change: Scientists

    Scientists have specified how many deaths can be attributed to man-made climate change during an extreme heatwave in two European cities in 2003. The study says that with climate change projected to increase the frequency and severity of future heatwaves, these results highlight an emerging trend. The authors suggest that such research gives policymakers better information about the damaging effects of heatwaves to help them respond to the future challenges of climate change.

  • U.S. suffered at least $8 billion climate-related disasters so far this year

    We are only halfway through 2016 and the United States has already seen eight weather and climate-related disasters* that have each met or exceeded $1 billion in damages. These eight disasters resulted in the loss of thirty lives, and caused at least $13.1 billion. Since 1980 the United States has sustained 196 weather and climate disasters in which overall damages/costs reached or exceeded $1 billion. The total cost of these 196 events exceeds $1.1 trillion.
