Natural Gas Is Not the Answer, New Study Finds

By Paul Brown

Natural gas will have to be phased out along with coal if the world is to be kept safe from dangerous climate change. And that seems likely to have to happen far sooner than most official forecasts, according to a new report.

If countries want to reach their Paris climate agreement goals of limiting the long-term world temperature rise to 1.5°C, then many of the proposals to increase gas production and distribution will be unnecessary. New terminals and pipelines will never be fully used and will become stranded assets.

Al Gore: Trump Fails to Derail the Energy Revolution

By Paul Brown

Donald Trump "cannot rewrite history," and no matter what he says or does the Paris agreement to limit climate change will survive and is even stronger as a result of Trump's rejection. This is the verdict pronounced by a former U.S. vice-president turned climate campaigner as Al Gore spurns Trump for a failed attempt to derail the energy revolution.

Concentrated Solar Works Day and Night With No Batteries Required

By Paul Brown

The massive expansion of solar panels on rooftops and solar farms across the world has captured the headlines, but the other established way of generating electricity from sunlight—concentrated solar power (CSP), or solar tower power—is also making great strides.

For a long time, using mirrors to concentrate the sun's rays to heat molten salt and produce superheated steam to drive a generator's turbines was thought to be a more promising technology than photovoltaic panels (PV), because it was originally cheaper.

Trump Betrays Science and Scientists With Climate Walkout

By Alex Kirby

President Donald Trump abandoned science with his decision to withdraw the U.S. from the Paris agreement on climate change, saying, "I was elected to represent the citizens of Pittsburgh, not Paris"—a wonderfully clear statement of his inability to recognize that the earth shares one atmosphere.

'Exxons of Agriculture' Take Over World Food System

By Paul Brown

The food industry and big agricultural concerns are driving climate change and at the same time threatening to undermine efforts to feed the world's growing population, according to GRAIN, an organization that supports small farmers.

Particularly singled out for criticism are the large chemical fertilizer producers that have gained access to the United Nations talks on climate change. GRAIN accuses them of behaving like the fossil fuel companies did in the 1990s, pushing false information in the hope of delaying real action on climate change.

Scientists Go to Coldest Place on Earth to Collect Ice Cores for Future Generations to Study

By Alex Kirby

An ambitious scientific expedition is due to start work on May 22 on Bolivia's second-highest mountain, Illimani. The researchers plan to drill three ice cores from the Illimani glacier, and to store two of them in Antarctica as the start of the world's first ice archive.

Oxygen Levels in Oceans Plummet as Planet Warms

By Tim Radford

U.S. scientists who have been warning that warmer oceans are more likely to be poorer in dissolved oxygen have now sounded the alarm: ocean oxygen levels are indeed falling, and seemingly falling faster than the corresponding rise in water temperature.
