• Proposed border wall will harm Texas plants, animals: Scientists

    In the latest publication on the potential impacts of a border wall on plants and animals, conservation biologists say that border walls threaten to harm endangered Texas plants and animals and cause trouble for the region’s growing ecotourism industry.

  • A court case could set precedent for climate change litigation

    A closely watched federal trial pitting two cities against major oil companies has taken surprising and unorthodox turns. Stanford researchers examine the case, which could reshape the landscape of legal claims for climate change-related damages.

  • U.K.'s best cyber defenders compete for chance to take on the U.S. cyber best

    Inter-ACE, now in its third year, was established to help resolve the vast and growing cyber security skills gap, with an estimated shortfall of 1.8 million workers worldwide by 2022. More than 130 students representing eighteen of the U.K.’s top cybersecurity universities battled it out at the Inter-ACE 2018 cybersecurity challenge, hosted by the University of Cambridge. The competition, supported by GCHQ’s National Cyber Security Center, and designed to attract the next generation of cybersecurity talent.

  • Water crisis spurring protests in Iran

    A lack of water has been spurring protests in Iran against the regime since the beginning of the year, Reuters reported Thursday. The water crisis have taken place mostly in Isfahan, located in central Iran, and, the Khuzestan province in the west, which is largely inhabited by non-Persian Arabs who call the region Ahwaz.

  • Climate-proofing to meet increased frequency, intensity of extreme weather events

    Man-made climate change has been proven to have increased recent extreme rainfall and associated floods; coastal flooding due to sea-level rise; heatwaves in Australia, China, and Europe; and increased risks of wildfires with implications for humans and animals, the environment, and the economy. Climate proofing can help to limit these impacts.

  • Geoengineering polar glaciers to slow sea-level rise

    Targeted geoengineering to preserve continental ice sheets deserves serious research and investment, argues an international team of researchers. Without intervention, by 2100 most large coastal cities will face sea levels that are more than three feet higher than they are currently.

  • We need laws on geoengineering, and soon

    Humans have been accidentally altering the planet’s climate for thousands of years. Soon, it may be possible alter it intentionally. The deliberate, large-scale manipulation of climate is called geoengineering. The term encompasses a variety of proposals, from pulling carbon dioxide out of the atmosphere to reflecting sunlight back into space in an attempt to slow the earth’s warming. Global geoengineering tactics haven’t yet been deployed, but as climate change starts to spin out of control, support for some forms of geoengineering seems to be growing.

  • The effects of climate change on California watersheds

    California relies on the Sierra Nevada snowpack for a significant portion of its water needs, yet scientists understand very little about how future changes in snowpack volume and timing will influence surface water and groundwater. Now researchers are developing an advanced hydrologic model to study how climate change might affect California watersheds.

  • Climate change to fuel more extreme heat waves in western U.S. by 2020

    Human-caused climate change will drive more extreme summer heat waves in the western United States, including in California and the Southwest as early as 2020, new research shows. Understanding the driving forces behind the projected increase in occurrence and severity of heat waves is crucial for public health security and necessary for communities to develop extreme heat mitigation strategies, said the authors.

  • Climate change could force over 140 million to migrate within countries by 2050

    The worsening impacts of climate change in three densely populated regions of the world could see over 140 million people move within their countries’ borders by 2050, creating a looming human crisis and threatening the development process, a new World Bank Group report finds.

  • Addressing climate migration within borders helps countries plan, mitigate effects

    Migration in response to climate change is a big topic in the media. But the focus is all too often on either international cross-boundary movements or short-term population displacement from major floods or droughts. While these forms of population movement are important, they are by no means the whole story. A new report is the first to focus on longer-term climate impacts on crop and water resources and the ways in which they may influence internal migration.

  • L.A. could achieve independence from imported water

    During the height of the California drought that began in late 2011, Los Angeles imported 89 percent of its water from more than 200 miles away — an energy-intensive process. After a yearlong reprieve, Southern California is again under severe water scarcity conditions: Only 2 1/2 inches of rain have fallen in Los Angeles during the past twelve months. This time around, could Los Angeles shift its dependence from imported water to local water? A new report says the city could, eventually — if it does a better job of capturing local stormwater, increases the use of recycled water, cleans up groundwater and steps up conservation measures.

  • South Africa can avoid a national water crisis

    Even if South Africa uses less water and applies all of government’s existing plans, the country will still face a water crisis in the next twenty years. Solutions are within reach – but turning things around will take significant financial investment and political will. A new study sets out aggressive measures to offset guaranteed water shortages in the future.

  • Warm Arctic means colder, snowier winters in Northeastern U.S.

    Scientists have linked the frequency of extreme winter weather in the United States to Arctic temperatures. “Warm temperatures in the Arctic cause the jet stream to take these wild swings, and when it swings farther south, that causes cold air to reach farther south. These swings tend to hang around for awhile, so the weather we have in the eastern United States, whether it’s cold or warm, tends to stay with us longer,” one scientist explains.

  • Several ways limit global temperature rise to 1.5°C

    There are several ways to limit global temperature rise to 1.5°C by 2100, new research says. The study is the first to look at how socioeconomic conditions such as inequalities, energy demand, and international cooperation might affect the feasibility of achieving these goals, and also considers technological and resource assumptions.
