“Here’s the scientific dirt: Soil can help reduce global warming.
While farm soil grows the world’s food and fiber, scientists are examining ways to use it to sequester carbon and mitigate greenhouse gas emissions.“We can substantially reduce atmospheric carbon by using soil. We have the technology now to begin employing good soil practices to reduce greenhouse gas emissions,” said Johannes Lehmann, Cornell professor of soil and crop sciences, co-author of the Perspectives piece, “Climate-smart Soils,” published in Nature, April 6.Decreasing greenhouse gas emissions, sequestering carbon and using prudent agricultural management practices that tighten the soil-nitrogen cycle can yield enhanced soil fertility, bolster crop productivity, improve soil biodiversity, and reduce erosion, runoff and water pollution. These practices also buffer crop and pasture systems against the impacts of climate change.
Currently, Earth’s atmosphere holds about 830 petagrams (1 trillion kilograms) of carbon and humans add about 10 petagrams of carbon to the atmosphere every year, because of industrial and agricultural waste, and fossil-fuel burning vehicles, according to Lehmann. Soils, however, hold about 4,800 petagrams of carbon to a depth of 2 meters, which is six times the amount of carbon dioxide currently in the atmosphere. The good news is that soils have the potential to hold even more, said the scientists.”

“The one bright spot amid the generally gloomy news about climate change, and the Trump administration’s resistance to doing anything about it, is the determination of a number of state governments to take action on their own.
California, as usual, has commanded the headlines on this score, having just strengthened its commitment to reducing greenhouse gas emissions. Now the nine Northeastern states that form the Regional Greenhouse Gas Initiative have done much the same, in a further rebuke to the know-littles and do-nothings like Scott Pruitt, the administrator of the Environmental Protection Agency, who are now calling the shots on climate policy in Washington.
The nine states, including Connecticut, Massachusetts and New York, last week agreed to reduce greenhouse gas emissions from power plants an additional 30 percent by 2030, on top of the 40 percent cut they have already achieved since the program began in 2009. R.G.G.I., as the initiative is known, was the nation’s first multistate greenhouse gas initiative. From the beginning (and despite the defection of New Jersey’s Gov. Chris Christie), it has had the backing of governors from both parties. More important, it has quietly achieved substantial emissions reductions at little cost to the states’ economies or to their consumers.”
“SAN FRANCISCO — A start-up company is trying to turbocharge a type of battery that has been a mainstay for simple devices like flashlights and toys, but until now has been ignored as an energy source for computers and electric cars.Executives at Ionic Materials, in Woburn, Mass., plan to announce on Thursday a design breakthrough that could make solid-state alkaline batteries a viable alternative to lithium-ion and other high-energy storage technologies.”
“Stanford, Calif. — California faces serious risks from climate change. Some are already being felt, like the severe heat this summer and recent episodes of extremely low snowpack in the mountains, which the state depends on for much of its water. Those are among the key messages in a new climate science report now under review in the White House. The good news is that California has been working hard to catch up with the climate change that has already happened, and to get ahead of what is still to come.
The past five years have painted a clear picture of what is in store for California, according to numerous scientific studies that underpin the new assessment: Rising temperatures will bring more frequent and severe hot spells, intensifying heat stress; more precipitation will fall as rain rather than snow, increasing storm water runoff; snow that does fall will melt earlier in the year, leaving less for the warm, dry season; and more moisture will be drawn out of soils and vegetation, increasing stress on crops and ecosystems. All of this will lead to more frequent and severe water deficits, punctuated by wet periods with increasing flood risk.”
“Can the courts fix climate change?
Several groups and individuals around the United States have gone to court to try to do what the Trump administration has so far declined to do: confront the causes and effects of global warming.In California, two counties and a city recently sued 37 fossil fuel companies, seeking funds to cover the costs of dealing with a warming world. In Oregon, a federal lawsuit brought on behalf of young people is moving toward a February trial date, though the so-called children’s suit could be tossed out before that. And more than a dozen state attorneys general have sued to block Trump administration moves to roll back environmental regulations.
Efforts in the United States are part of a wave of litigation around the world, including a 2015 decision in which a court in the Netherlands ordered the Dutch government to toughen its climate policies; that case is under appeal. A 2017 report from the United Nations Environment Program found nearly 900 climate litigation suits in more than 20 countries. In Switzerland, a group of nearly 800 older women known as Senior Women for Climate Protection have sued their government over climate change. In New Zealand, a court recently heard a climate case brought by a law student, Sarah Lorraine Thomson; a decision is pending.”

“California, which has long been a pioneer in fighting climate change, renewed its commitment to reducing greenhouse gas emissions last week by extending, to 2030, its cap-and-trade program, which effectively puts a price on emissions. It’s a bold, bipartisan commitment that invites similarly ambitious policies from other states, and it sends a strong signal to the world that millions of Americans regard with utmost seriousness a threat the Trump administration refuses to acknowledge, let alone reckon with.”
“Attention now turns to the Northeast, where nine states, including New York, Connecticut and Massachusetts, are part of what is known as the Regional Greenhouse Gas Initiative, which, like California’s effort, is a market-based cap-and-trade program that goes beyond state boundaries. So far, R.G.G.I., as it known for short, has helped reduce emissions from power plants in the region by 40 percent between 2008 and 2016, according to the Acadia Center, a research and public interest group. States are now negotiating the future of the program beyond 2020.”
“Over the past six years, rooftop solar panel installations have seen explosive growth — as much as 900 percent by one estimate.That growth has come to a shuddering stop this year, with a projected decline in new installations of 2 percent, according to projections from Bloomberg New Energy Finance.
A number of factors are driving the reversal, from saturation in markets like California to financial woes at several top solar panel makers.But the decline has also coincided with a concerted and well-funded lobbying campaign by traditional utilities, which have been working in state capitals across the country to reverse incentives for homeowners to install solar panels.
Utilities argue that rules allowing private solar customers to sell excess power back to the grid at the retail price — a practice known as net metering — can be unfair to homeowners who do not want or cannot afford their own solar installations.”
“So, what’s the big deal? Support for putting a price on carbon emissions is hardly newsworthy. Virtually every environmentalist thinks it’s crucial; many believe it’s the single most important thing we could do.But Michael Crothers doesn’t work for an environmental organization. He’s the president of Shell Canada. Steve Williams is head of Suncor, Canada’s largest oil company. Ben van Beurden is chief executive of Royal Dutch Shell. Bob Dudley is chief executive of BP.
Darren Woods? That statement was part of his first blog post in his new job: chairman and chief executive of Exxon Mobil, replacing Rex Tillerson, the new secretary of state — who also endorsed a carbon tax.All of these energy companies favor a tax on every ton of carbon emissions, which is one of two ways to price emissions. The other way is called “cap and trade” — creating a market in emissions by imposing a maximum. Companies who want to exceed the level can buy the right from others who pollute less.
Let’s assume for now that this support for a carbon tax is genuine. (More about this later.) In the age of Trump, this is a gift that shouldn’t be wasted.Could it actually happen?I’m not proposing to bet on its success, but a carbon tax plan written by the Climate Leadership Council, a group of prominent Republicans that includes George Shultz, James A. Baker III and Henry Paulson, has at least started a debate. The group proposes taxing each ton of carbon emissions — and then returning all the money to Americans by sending everyone a quarterly dividend check.”
