Climate Change Two-thirds of glacial melting in the past 20 years was due to human-caused climate change, according to new research published in the journal Science, the Guardian reported. Researchers used computer models to identify how the role of factors like greenhouse gas emissions and land use change compared to the role of volcanic eruptions […]
Water Scarcity New research has quantified the amount of water being virtually exported from and imported to Chinese provinces, confirming that arid regions are sending huge amounts of water to more water-rich areas in the form of agricultural products, Reuters reported. The research, published in the journal Environmental Science and Technology, found that this imbalance […]
Climate Change Large areas of Southeast Asia used for rice production, including crop regions in Bangladesh and Vietnam, could disappear as global sea levels rise, according to a new study that takes into account the melting of the Western Antarctica ice sheet, the Guardian reported. Studies recently found that the ice sheet has been destabilized […]
One year later, Circle of Blue’s senior editor Keith Schneider returns to India for our second round of reporting on water, food, energy problems in the region.
Oceans are rising faster and becoming more acidic, snowpack is decreasing, and the Earth is heating up. The latest report on climate change from an international panel of scientists is a story of epochal transformations to the Earth’s land, air, and water systems. Greenhouse gas concentrations in the atmosphere are the highest in 800,000 years, […]
Water Infrastructure The United States spends just 2 percent of its gross domestic product on water infrastructure, while China spends 7 percent and India spends 5 percent, according to the U.S. Army Corps of Engineers, Bloomberg News reported. The U.S. Environmental Protection Agency estimates that the U.S. needs to spend $US 384 billion by 2030 […]
One of the reasons that climate change is such a big issue is because the global climate is an integral part of the Earth’s entire ecosystem, tied to so many of the big and little things that society cares about.
Water Supply A new study about Andean glaciers found that the pace of ice retreat in the tropical Andes is “unprecedented,” putting the water supply for many South American communities at risk, the Guardian reported. The study, published in Cryosphere, claims that an average temperature rise of 0.7 degree Celsius over 70 years is behind […]
India’s climate outlook in the upcoming century is bleak, according to an analysis of eighteen different climate models reported in The Hindu. Average annual surface temperatures are expected to rise by 4-7 degrees Celsius, part of a warmer world with heat waves severe drought, and major floods, according to a World Bank-sponsored report. Read the […]
The Supreme Court seemed ready on Tuesday to overturn a lower court’s ruling in a case about stormwater pollution in the Los Angeles area, the Associated Press reports.
