This is where the world could support new forests. The map excludes existing forests, urban areas, and agricultural lands. J. BASTIN, ET. AL., SCIENCE 365, 76, 2019

. . . What if we grew new forests on vacant city lots, old industrial buildings — even golf courses?

For the first time, scientists have sought to quantify this thought experiment. How many trees could be planted on every available parcel of land on Earth, where they could go, and what impact could that have on our survival?

They concluded that the planet could support nearly 2.5 billion additional acres of forest without shrinking our cities and farms, and that those additional trees, when they mature, could store a whole lot of the extra carbon — 200 gigatons of carbon, to be precise — generated by industrial activity over the last 150 years.

Parts of the study — led by researchers at ETH Zurich, a university that specializes in science, technology and engineering — were immediately criticized.

. . . In most of the western highlands, the question is no longer whether someone will emigrate but when. “Extreme poverty may be the primary reason people leave,” Edwin Castellanos, a climate scientist at the Universidad del Valle, told me. “But climate change is intensifying all the existing factors” . . . Farming, Castellanos has said, is “a trial-and-error exercise for the modification of the conditions of sowing and harvesting times in the face of a variable environment.” Climate change is outpacing the ability of growers to adapt.

If the world hopes to make meaningful progress on climate change, it won’t be enough for cars and factories to get cleaner. Our cows and wheat fields will have to become radically more efficient, too.

That’s the basic conclusion of a sweeping new study issued Wednesday by the World Resources Institute, an environmental group. The report warns that the world’s agricultural system will need drastic changes in the next few decades in order to feed billions more people without triggering a climate catastrophe.

Two giant sinkholes near Wink, Texas, may just be the tip of the iceberg, according to a new study by a Southern Methodist University, Dallas geophysical team that found alarming rates of new ground movement extending far beyond the infamous sinkholes . . .

 . . . Now the team has discovered that various locations in large portions of four Texas counties are also sinking and uplifting.

 . . . ”These hazards represent a danger to residents, roads, railroads, levees, dams, and oil and gas pipelines, as well as potential pollution of ground water," Lu said. "Proactive, continuous detailed monitoring from space is critical to secure the safety of people and property" . . .
