China plans cloud seeding to protect grain crop from drought

China plans cloud seeding to protect grain crop from drought

The Associated Press reports: China says it will try to protect its grain harvest from record-setting drought by using chemicals to generate rain, while factories in the southwest waited Sunday to see whether they would be shut down for another week due to shortages of water to generate hydropower. The hottest, driest summer since the government began recording rainfall and temperature 61 years ago has wilted crops and left reservoirs at half their normal water level. Factories in Sichuan province…

The Anthropocene demands a massive realignment of priorities

The Anthropocene demands a massive realignment of priorities

Martin Rees and Charles F. Kennel write: Our Earth has existed for 45 million centuries; and humans for a few thousand. But this century is the first when our species is so numerous—and so demanding of energy and natural resources—that we risk collectively despoiling our planet. It’s surely an ethical imperative that we should not deny future generations the wonders and beauty of the natural world. Policy must, in the words of the Brundtland Commission, “meet the needs of the…

The legacy of James Lovelock

The legacy of James Lovelock

John Gribbin writes: Jim Lovelock (never ‘James’) is remembered as the father of the Gaia hypothesis: the idea that Earth is a self-regulating living organism. Few accepted his argument that this should be elevated to the status of a theory, even though it generated predictions about environmental changes that were borne out by subsequent observations. As a heuristic model, however, Gaia profoundly influenced thinking about the environment and how we interact with it, giving rise to the field of Earth-system…

Desertification in an Iraqi bread basket

Desertification in an Iraqi bread basket

Tessa Fox reports: Palm branches whip back as Hussein Ibrahim walks through his densely planted land in Al Fao, the very last village in Iraq’s south as it reaches the Persian Gulf. Affectionately known as Abu Yusuf in reference to his eldest son, Ibrahim explains that farming is his culture. “I’ve inherited this land from my grandfather and even the father of my grandfather had it. We were all farmers; we were born to be farmers,” says the father of…

Can farmers fight climate change? New U.S. law gives them billions to try

Can farmers fight climate change? New U.S. law gives them billions to try

Science reports: When settlers plowed the North American prairie, they uncovered some of the most fertile soil in the world. But tilling those deep-rooted grasslands released massive amounts of underground carbon into the atmosphere. More greenhouse gases wafted into the skies when wetlands were drained and forests cleared for fields. Land conversion continues today, and synthetic fertilizer, diesel-hungry farm machinery, and methane-belching livestock add to the climate effects; all told, farming generates 10% of climate-affecting emissions from the United States…

Scientists warn of dire effects as Mediterranean heats up

Scientists warn of dire effects as Mediterranean heats up

The Associated Press reports: While vacationers might enjoy the Mediterranean Sea’s summer warmth, climate scientists are warning of dire consequences for its marine life as it burns up in a series of severe heat waves. From Barcelona to Tel Aviv, scientists say they are witnessing exceptional temperature hikes ranging from 3 degrees Celsius (5.4 Fahrenheit) to 5 degrees Celsius (9 Fahrenheit) above the norm for this time of year. Water temperatures have regularly exceeded 30 C (86 F) on some…

Ponder the miracle of a U.S. climate law

Ponder the miracle of a U.S. climate law

Bud Ward writes: Miracles indeed can happen. And sometimes do. Such is the case with enactment of major climate legislation, part of the Inflation Reduction Act now, with President Joe Biden’s signature, enacted. Not just passed by the Senate and the House on strict party-line votes, but passed by each chamber as presented to them, without amendments, without differences requiring a time-consuming and inscrutable House/Senate conference committee. And, it must be emphasized, without a single vote by the Republican narrow…

America is going to have a ‘Heat Belt’

America is going to have a ‘Heat Belt’

The Atlantic reports: When the heat index—the temperature multiplied by humidity—reaches 80 degrees, the National Weather Service advises Americans to take caution. When it reaches 90, that advisory gets bumped to possibly dangerous; at 100, it’s likely so. At a heat index of 125 or above, the National Weather Service warns of “extreme danger” and describes its effect on the body concisely: “heat stroke highly likely.” Until now, that kind of extreme heat has been limited to relatively small parts…

World’s largest ice sheet threatened by warm water surge

World’s largest ice sheet threatened by warm water surge

Nature reports: Westerly winds are thrusting warm waters towards the East Antarctic ice sheet, and have thinned the region’s ice masses at alarming rates over recent decades, a study has found. Scientists say that the research, published in Nature Climate Change on 2 August, also helps to resolve one of the largest uncertainties in projections of future sea-level rise: how vulnerable the East Antarctic Ice Sheet, the world’s largest, is to ocean warming. Ice shelves float on the ocean, extending…

Meet the teenager who helped push Florida toward cleaner energy

Meet the teenager who helped push Florida toward cleaner energy

NPR reports: For most of his 15 years, Levi Draheim led a beachy life on a barrier island on Florida’s east coast, swimming, surfing and sailing in the nearshore waves. He dreamed of someday becoming a marine biologist. But Levi’s world is changing. Warming temperatures led to widespread Sargassum seaweed and harmful algae blooms in the Atlantic Ocean and 156-mile Indian River Lagoon, which together encircle the island. The seaweed and algae blooms have left beaches stinking with rotting seaweed…

Arctic warming is happening faster than previously described, analysis shows

The New York Times reports: The rapid warming of the Arctic, a definitive sign of climate change, is occurring even faster than previously described, researchers in Finland said Thursday. Over the past four decades the region has been heating up four times faster than the global average, not the two to three times that has commonly been reported. And some parts of the region, notably the Barents Sea north of Norway and Russia, are warming up to seven times faster,…

Democrats finally jettison carbon pricing in favor of tax incentives to counter climate change

Democrats finally jettison carbon pricing in favor of tax incentives to counter climate change

Inside Climate News reports: The nation’s first comprehensive climate law, expected to be sealed with a vote in the U.S. House of Representatives on Friday, will not look anything like the program imagined by either climate economists or those in Washington and the environmental movement who had faith in bipartisan action. From the time that the world first agreed to act on climate change 30 years ago at the Earth Summit in Rio de Janeiro, environmentalists talked about putting a…

The fervent debate over the best way to confront climate change

The fervent debate over the best way to confront climate change

By Madeline Ostrander, August 12, 2022 In the late 1950s, Ian Burton, then a geographer at the University of Chicago, learned about a troubling conundrum with levees. These expensive and engineering-intensive strategies — which the U.S. Army Corps of Engineers favored for reining in floods along big river floodplains — worked well for holding back intermediate amounts of water. But they gave people a false sense of safety. After a levee went up, sometimes more people actually built and moved…

Europe on course to suffer worst drought in 500 years

Europe on course to suffer worst drought in 500 years

The Daily Mail reports: Germany’s most-important river is running dry as Europe suffers through a drought that is on course to become its worst in 500 years, with terrifying wildfires burning once again in France. Water levels in the Rhine – which carries 80 per cent of all goods transported by water in Germany, from its industrial heartlands to Dutch ports – are now so low that it could become impassable to barges later this week, threatening vital supplies of…

Carbon-reduction plans rely on technology that doesn’t exist

Carbon-reduction plans rely on technology that doesn’t exist

Naomi Oreskes writes: At last year’s Glasgow COP26 meetings on the climate crisis, U.S. envoy and former U.S. secretary of state John Kerry stated that solutions to the climate crisis will involve “technologies that we don’t yet have” but are supposedly on the way. Kerry’s optimism comes directly from scientists. You can read about these beliefs in the influential Intergovernmental Panel on Climate Change (IPCC) Integrated Assessment Models, created by researchers. These models present pathways to carbon reductions that may…

Caring about the unborn should mean caring about the future of our planet

William MacAskill writes: Humanity, today, is in its adolescence. Most of a teenager’s life is still ahead of them, and their decisions can have lifelong effects. Similarly, most of humanity’s life lies ahead – an estimated 118 billion people have already lived, but vastly more people, perhaps thousands or even millions of times that number, are yet to be born. And some of the decisions we make this century will impact the entire course of humanity’s future. Contemporary society does…
