• An Umbrella to Combat Warming

    Research examines the possibility of spraying tiny particles into the stratosphere to block the sun a bit and cool the planet. Shielding the Earth with a mist of tiny particles sounds like the stuff of sci-fi movies, but since it was first proposed in the 1950s the idea has gained traction among scientists around the world to shield us not from extraterrestrials, as Hollywood might have it, but from the sun. Known as solar geoengineering, the concept is to send planes into the stratosphere — 6 to 31 miles above the Earth — to spray particles that can reflect sunlight back into space and cool the planet.

  • Climate Change Could Cause Drought in Wheat-Growing Areas

    In a new study, researchers found that unless steps are taken to mitigate climate change, up to 60 percent of current wheat-growing areas worldwide could see simultaneous, severe and prolonged droughts by the end of the century. Wheat is the world’s largest rain-fed crop in terms of harvested area and supplies about 20 percent of all calories consumed by humans.

  • India-Pakistan Nuclear War Could Kill Millions, Lead to Global Starvation

    A nuclear war between India and Pakistan could, over the span of less than a week, kill 50-125 million people—more than the death toll during all six years of World War II, according to new research. The researchers calculated that an India-Pakistan war could inject as much as 80 billion pounds of thick, black smoke into Earth’s atmosphere. That smoke would block sunlight from reaching the ground, driving temperatures around the world down by an average of between 3.5-9 degrees Fahrenheit for several years. Worldwide food shortages would likely come soon after. Today, India and Pakistan each have about 150 nuclear warheads at their disposal, and that number is expected to climb to more than 200 by 2025.

  • Designing the Coastal City of the Future

    Boston is situated along the Gulf of Maine, which is warming faster than 99 percent of the ocean due, in part, to changing sea patterns from melting ice in Greenland and the Arctic Ocean. Coupled with increased heat and precipitation, the rising sea level is threatening the low-lying city, much of which was built on landfill over the past 300 years along a 50-square-mile harbor. To save the 685,000-person city, the local government is calling on architects to help implement one of the most ambitious municipal resiliency plans in the United States: Climate Ready Boston. Launched in 2016 by Mayor Martin J. Walsh, Climate Ready Boston is an initiative to prepare the city for the long-term impacts of climate change.

  • Arctic Ice Is Melting Faster Than Expected. These Scientists Have a Radical Idea to Save It.

    glaciers, polar land, and sea ice are rapidly melting, much faster than many scientists expected, as the Intergovernmental Panel on Climate Change’s (IPCC) report on oceans and the cryosphere released Wednesday reiterated. During a five-day heat wave this summer, Greenland lost more than 60 billion tons of ice, including the biggest loss in a 24-hour period since record-keeping began. Recent projections warn that Arctic summers could be nearly ice-free in 10 to 40 years. These grim warnings have prompted more researchers to apply technological solutions that intervene in the earth’s climate systems to slow the impacts of global warming, also known as “geoengineering.”

  • Ecosystem Investments Could Minimize Storm Damage

    A new study provides information on how to invest in natural coastal ecosystems that the Bahamian government, community leaders and development banks are applying in post-disaster recovery and future storm preparation in the Bahamas.

  • 250,000 Cubic Meters of Ice in Danger of Breaking Off Europe's Mont Blanc

    Highlighting concerns about global warming, Italian authorities now fear that part of the glacier on Mont Blanc, Europe’s highest mountain, is at risk of collapse. Experts have been monitoring the Planpicieux glacier on Mont Blanc for some time and concerns have been mounting in Italy that a section of the glacier is at risk of collapsing. Mayors of the picturesque ski towns in the area have been taking civil defense measures, including plans for evacuation on a short notice.

  • Can Going Nuclear Combat Climate Change?

    To mitigate climate change, the proportion of low-carbon electricity generation must increase from today’s 36 percent to 85 percent by 2040, the International Energy Agency (IEA) says. IEA and other advocates argue that nuclear power could help fill this gap. However, barriers to a nuclear energy renaissance include safety concerns, aging reactors and high costs for new ones.

  • Global Climate in 2015-2019 Shows Climate Change Accelerating

    The tell-tale signs and impacts of climate change – such as sea level rise, ice loss, and extreme weather – increased during 2015-2019, which is set to be the warmest five-year period on record, according to the World Meteorological Organization (WMO). Greenhouse gas concentrations in the atmosphere have also increased to record levels, locking in the warming trend for generations to come.

  • NYC Building a Seawall to Protect City from Rising Seas

    On Staten Island, the section of New York City which suffered most of Superstorm Sandy’s devastation, most of the homes destroyed by the storm still sit empty. City engineers have concluded that there was no point fixing and rehabilitating these homes until other measures are taken to protect the Staten Island from the next devastating storms. And climate change will only make these storms more frequent and more intense. These other measures are now underway.

  • Global Warming Has “Profound Consequences” for Oceans, Cryosphere

    The ocean and the cryosphere – the frozen parts of the planet – play a critical role for life on Earth. A total of 670 million people in high mountain regions and 680 million people in low-lying coastal zones depend directly on these systems. Four million people live permanently in the Arctic region, and small island developing states are home to 65 million people. Global warming has profound consequences for these ecosystems: The ocean is warmer, more acidic and less productive; melting glaciers and ice sheets are causing sea level rise; and coastal extreme events are becoming more severe.

  • Global Temperatures Rising More Quickly, Warns UN

    Sea-level rise, ice loss, extreme weather and other effects of climate change are increasing, according to the United Nations’ weather agency. The period from 2015 to the end of 2019 is likely to be the warmest five-year period on record globally, the World Meteorological Organization (WMO) said. Last year there was the largest number of tropical cyclones of any year since 2000 and large parts of Africa, central America, Brazil, the Caribbean and Australia have experienced more frequent droughts since 2015.

  • California Wildfires Can Impact Water Availability

    In recent years, wildfires in the western United States have occurred with increasing frequency and scale. Climate change scenarios in California predict prolonged periods of drought with potential for conditions even more amenable to wildfires. The Sierra Nevada Mountains provide up to 70 percent of the state’s water resources, yet there is little known on how wildfires will impact water resources in the future.

  • In the Event of a Killer Asteroid, Volcanic Apocalypse, or Nuclear Holocaust, Mushrooms Could Save Humanity from Extinction

    About 66 million years ago, an asteroid plummeted through Earth’s atmosphere and crashed into the sea floor, creating an explosion over 6,500 times more powerful than the nuclear bomb the U.S. dropped on Hiroshima. The impact sent clouds of debris and sulfur into Earth’s atmosphere, blocking the sun’s light and warmth for about two years. Photosynthesis ground to a halt, which meant no more plant growth. The surviving dinosaurs starved to extinction. But fossil records show that fungi thrived in the aftermath. “Blot out the sun, and even the best-prepared survivalist, a master of the wilderness, will starve to death along with everyone else,” Bryan Walsh writes in his new book, End Times. In order to survive, he says, people would need to adopt sunlight-free agriculture — cultivating mushrooms, rats, and insects.

  • Bottled Water Is Sucking Florida Dry

    Florida has the largest concentration of freshwater springs in the world, but they are being devastated by increasing pollution and drastic declines in water flow. Some springs have dried up from overextraction; others have shown signs of saltwater intrusion and harmful algae blooms. The answer to this problem is simple: No more extraction permits should be granted, and existing permits should be reduced with the goal of eliminating bottled water production entirely in Florida. But that simple solution is not being implemented. In the next few months, Nestlé, the largest bottled-water company in the world, is set to renew its permit at Ginnie Springs, one of the most popular recreational attractions along the Santa Fe River,” Sainato and Skojec write. “The permit allows Nestlé to take one million gallons per day at no cost, with just a one-time $115 application fee.”
