Green Cement and climate change

Green cement? Captured carbon may fuel new markets and help climate

Capturing planet-warming carbon dioxide and turning it into useful products, from plastics to jet fuel, could make climate action cheaper and become a good business – but market obstacles need to be overcome first, researchers said this week.

11,000 scientists warn: climate change isn’t just about temperature

Exactly 40 years ago, a small group of scientists met at the world’s first climate conference in Geneva. They raised the alarm about unnerving climate trends. Today, more than 11,000 scientists have co-signed a letter in the journal BioScience, calling for urgently necessary action on climate.

Richer nations urged to boost protection against wild weather as economic losses jump

Economic losses caused by the most extreme weather events, from hurricanes to wildfires, are surging fastest in parts of the world outside the tropics – places that once saw relatively few such disasters, scientists and statisticians have warned.

For Rachel Carson, wonder was a radical state of mind

In 1957, the world watched in wonder as the Soviet Union launched Sputnik 1, the first artificial satellite, into outer space. Despite Cold War anxieties, The New York Times admitted that space exploration ‘represented a step toward escape from man’s imprisonment to Earth and its thin envelope of atmosphere’.

Discovering lost skills at the School of Artisan Food

Hidden away in the ancient Sherwood Forest on The Welbeck Estate, the ancestral seat of the Dukes of Portland, is the rather unique School of Artisan Food. The Estate has a fascinating history, but it is its reinvention through The Welbeck Project, of which the School is a part, which will see it prosper and thrive for future generations.

General Sherman, a Californian giant sequoia, is the biggest tree in the world. For a brief period in the late 19th century it was renamed Karl Marx.

A future just, green and free, under a tree named Karl Marx

California has long been seen as the place where the future takes shape, and the state has drawn to it seekers from all over the world and across the political spectrum. It’s a Mecca for the local- and organic-food movement’s pilgrims as well as for today’s disciples of techno-libertarians such as Peter Thiel and Elon Musk.

How to rewild your garden and create a tiny rainforest

Many scientists believe that halting global warming at 1.5°C will require us to invent Negative Emission Technologies – machines that can suck climate warming gases like carbon dioxide (CO₂) from the air. But such technology already exists and has done for over two billion years.

‘Asia undermining efforts to reduce coal dependence,’ says UN

Asia’s dependence on coal is completely at odds with the Paris Agreement to combat climate change, a UN official has warned, as experts from the region met in Bangkok to find ways to intensify efforts to stem global warming.
