Megafires and orchard health

The frequent and massive megafires in places like Canada and the American west have led to a lot of research on the impact of smoke on humans but there has been less study of the effects of smoke on plant health. Researchers at the University of California, Davis have found that trees are just as […]

The last coal plant in Britain

The Industrial Revolution, which basically got underway in the mid-19th century, was largely enabled by coal, which fueled iron manufacturing, railroads, steam engines, and more. Most of these things got their start in Britain, which inspired the rest of the world to follow suit. The world’s first coal-burning power plant began producing electricity at the […]

Renegade geoengineering

As the dangers of climate change continue to grow, so has interest in geoengineering – deliberate tinkering with the earth’s climate system. In particular, stratospheric solar geoengineering – releasing aerosols into the stratosphere to reduce the amount of heat from the sun reaching the Earth – is attracting increasing interest. Scientists at Harvard, Cornell, Colorado […]

Big Food and greenhouse gas emissions

The global food system is responsible for as much as 40% of human-generated greenhouse gas emissions. The investor advocacy group Ceres has tracked whether the 50 largest North American food and agriculture companies have set targets to lower their emissions and whether doing so has actually resulted in lower emissions. The emissions from food and […]

A structural battery

The size and especially the weight of batteries is a critical factor for most things that use them. Battery weight is a key limitation for computers and cell phones. It is even more of a limitation for electric cars, ships, or planes. If the battery of a device or vehicle can also function as a […]

Ocean geoengineering

As greenhouse gas emissions continue to be dangerously large and the perils of climate change are increasingly apparent, the world is increasingly exploring ways to deliberately intervene in climate systems. A number of these ideas involve introducing substances into the atmosphere, but there are also ways to tinker with the oceans. The oceans naturally absorb […]

Wildlife crossings

Every year, there are one to two million collisions between motor vehicles and large animals in the U.S. About 200 people are killed annually. Counting smaller vertebrates, around a million animals are killed by vehicles each day. Research has shown that global warming is triggering widespread species redistribution. As a result, more and more animals […]
