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.”

The Water Wars Are Here
Everyone remembers the scene in Chinatown when Jack Nicholson almost gets his nose sliced off, but many do not recall what the dispute was about. It wasn’t drug smuggling or gun running that got Nicholson’s character slashed. It was water rights. Since the film was released in 1974, the question of who will get the limited water in the American West, particularly the all-important flow of the Colorado River, has grown even more contentious. Dystopian novels and movies predict a future in which people fight it out for every last drop of water to quench the thirst of expanding cities, parched agriculture, and wasteful suburban grass lawns. But the future is already here.

Can We Engineer Our Way Out of the Climate Crisis?
The Climate Apocalypse is upon us. More carbon monoxide has been discharged into the atmosphere in the last 50 years than in the whole of human history that went before. Carbon traps heat and the world is getting hotter. Heat holds water vapor and so rainfall is getting more frequent while heat waves last longer. Ice at the poles melts and coastal cities face inundation as sea levels rise. The doom confidently predicted by many climate scientists around the world is being met by optimism among other scientists who are employing innovative technologies that may transform the debate and offer hope for us all. These technological breakthroughs will impact all aspects of climate change from carbon emissions to food production and all forms of energy.

Soils Could Be Affected by Climate Change, Impacting Water and Food
Coasts, oceans, ecosystems, weather and human health all face impacts from climate change, and now valuable soils may also be affected. Climate change may reduce the ability of soils to absorb water in many parts of the world, according to a Rutgers-led study. And that could have serious implications for groundwater supplies, food production and security, stormwater runoff, biodiversity and ecosystems.

Climate Change Influences Magnitude of River Floods
Overflowing rivers can cause enormous damage: Worldwide, the annual damage caused by river floods is estimated at over 100 billion dollars - and it continues to rise. So far it has not been clear how climate change influences the magnitude of river floods. Until now: an large international study involving a total of 35 research groups provides clear evidence that changes in the magnitude of flood events observed in recent decades can be attributed to climate change.

These Dams Needed Replacing 15 Years Ago. Now Texas Will Drain Four Lakes Instead — Causing Other Problems.
Texas officials will start draining four lakes next week in Guadalupe County in Central Texas without a plan in place for when the lakes, and the 90-year-old dams that support them, will be rebuilt. Area homeowners, who got barely a month’s notice, said they felt blindsided by the plan, and they say it will slash their property values, kill their beloved century-old cypress trees and render the lakes — which have hosted water skiing tournaments for decades — unusable.

Microplastics Harming Our Drinking Water
Plastics in our waste streams are breaking down into tiny particles, causing potentially catastrophic consequences for human health and our aquatic systems. Approximately 300 million tons of plastic are produced globally each year and up to 13 million tons of that is released into rivers and oceans, contributing to approximately 250 million tons of plastic by 2025. Since plastic materials are not generally degradable through weathering or ageing, this accumulation of plastic pollution in the aquatic environment creates a major health concern.

Leak Suggests UN Agency Self-Censors on Climate Crisis after U.S. Pressure
Leaked communications suggest that the UN’s migration agency is censoring itself on the climate crisis and the global compact on migration, following pressure from the U.S. government. an email sent by a U.S.-based official of the International Organization for Migration (IOM) on 28 August to colleagues around the world relayed that the U.S. state department’s Bureau of Population, Refugees and Migration (PRM) told the agency documents related to program activities it funds “must not be in conflict with current [U.S. government] political sensitivities.” These sensitivities include mentioning climate change and the UN sustainable development goals.

Bill Gates Is Funding a Chemical Cloud That Could Put an End to Global Warming
Whether you agree or not, global warming is happening. As reported by the minds at NASA, human activity continues to exacerbate the problem. Currently, there is more carbon dioxide in our atmosphere than in all of human history. Two-thirds of extreme weather events from the past 20 years can be tied back to human activity, while both our summers and winters are getting much warmer. Bill Gates is currently backing a potential solution to global warming that centers around the technology of solar geoengineering.

Even for Non-Believers, These Are the Next Steps on Climate Change
Research indicates that we need to go beyond observing the wreckage of major storms and pondering trillion-dollar plans to attempt to mitigate carbon. Businesses, homeowners, and local governments must focus on what can be done today to address these direct threats to people and property. There are three major tools in the “what to do next” approach: probability, selection, and migration.

Damage Estimates for Hurricanes Like Dorian Don’t Capture the Full Cost of Climate Change-Fueled Disasters
Scientists say climate change is causing powerful hurricanes like Dorian to increasingly stall over coastal areas, which leads to heavy flooding. The U.S. government’s Fourth National Climate Assessment offered a range of climate change-induced losses of U.S. GDP which range from as low as 6 percent to as high as 14 percent by 2090. Aa more meaningful assessment of the costs of climate change – using basic economic principles I teach to undergrads – is a hell of a lot scarier.
