Just over a century ago in Ludwigshafen, Germany, a scientist named Carl Bosch assembled a team of engineers to exploit a new technique in chemistry. A year earlier, another German chemist, Fritz Haber, hit upon a process to pull nitrogen (N) from the air and combine it with hydrogen (H) to produce tiny amounts of ammonia (NH₃). But Haber’s process was delicate, requiring the maintenance of high temperatures and high pressure.

Evidence for man-made global warming has reached a “gold standard” level of certainty, adding pressure for cuts in greenhouse gases to limit rising temperatures, scientists said on Monday.

“It is, I promise, worse than you think.” That was was the first line of David Wallace-Wells’s horrifying 2017 essay in New York magazine about climate change. It was an attempt to paint a very real picture of our not-too-distant future, a future filled with famines, political chaos, economic collapse, fierce resource competition, and a sun that “cooks us.”

It’s OK to believe in climate change and be Republican. Actually, it's OK to believe in climate change and be a good Republican. A few months ago, I had lunch with a senior Republican official in Arizona. The conversation shifted to the environment and renewable energy.

OSLO (Reuters) - Evidence for man-made global warming has reached a “gold standard” level of certainty, adding pressure for cuts in greenhouse gases to limit rising temperatures, scientists said on Monday.

The move would be the administration’s most forceful effort to date to challenge the scientific consensus that greenhouse gas emissions are helping drive global warming. “The president wants people to be able to decide for themselves,” says a senior administration official.

As scientific projections of the effects of climate change become more robust, the threats posed by extreme storms, catastrophic flooding, heat waves, and droughts have gotten clearer and more frightening. The Intergovernmental Panel on Climate Change has predicted that global temperatures could rise 1.5 degrees Celsius above preindustrial levels – the threshold for severe effects of climate change – by 2040. By the turn of the century, temperatures could climb even higher, spelling disaster in some areas.

A new expansion has added environmental challenges to Sid Meier’s Civilization VI, the latest in a popular series of strategy video games that has been running since the 1990s. The expansion – called Gathering Storm – adds new features to the game, most notably anthropogenic climate change and natural disasters. The game involves developing a civilisation from its humble beginnings in the Stone Age to nowadays and beyond, while choosing from a vast array of technologies and cultural policies. As the game and the ages progress, your energy choices become increasingly important.

The promise of a Green New Deal has become a galvanizing force in US politics, inspiring climate activists and building much-needed pressure behind a sweeping federal climate plan. But the proposed environmental and economic policy package has contained a technical flaw from the start that’s coming into sharper relief as interest groups seek to translate its high-minded ideals into nuts-and-bolts policies.

While there are many drivers of climate, CO2 is the most dominant radiative forcing and is increasing faster than any other forcing.

On the surface it certainly can appear that way. But just because some of us are suffering through a particularly cold and snowy winter doesn’t refute the fact that the globe is warming as we continue to pump carbon dioxide and other greenhouse gases into the atmosphere. According to the National Aeronautics and Space Administration (NASA), the 10 warmest years on record have occurred since 1997. And the National Atmospheric and Oceanographic Administration (NOAA) reports that recent decades...

The world is literally a greener place than it was 20 years ago, and the data from NASA satellites has revealed a counterintuitive source for much of this new foliage: China and India. This surprising new study shows that the two emerging countries with the world’s biggest populations are leading the improvement in greening on land. The effect stems mainly from ambitious tree planting programs in China and intensive agriculture in both countries. In 2017 alone, India broke its own world record for the most trees planted after volunteers gathered to plant 66 million saplings in just 12 hours.

Who’s afraid of the Green New Deal? I’m not. It’s ambitious, aspirational, improbable, impractical — almost as audacious as putting a man on the moon. We used to be able to think big. Let’s do it again. Since the 14-page resolution was introduced in Congress this month by Sen. Edward J. Markey (D-Mass.) and Rep. Alexandria Ocasio-Cortez (D-N.Y.), critics have been falling over themselves to denounce the Green New Deal’s policies as prohibitively expensive...

Sea level rise, driven by climate change, is causing increased flooding during high tides along much of the U.S. coastline. Though such floods are usually minor, a new study suggests that car traffic patterns could help reveal how floods harm an area’s business revenues. Tidal flooding events “are not one in a hundred years or one in a thousand years. They’re once a week,” says Miyuki Hino, an environmental social scientist at Stanford University.

The age of climate panic is here. Last summer, a heat wave baked the entire Northern Hemisphere, killing dozens from Quebec to Japan. Some of the most destructive wildfires in California history turned more than a million acres to ash, along the way melting the tires and the sneakers of those trying to escape the flames. Pacific hurricanes forced three million people in China to flee and wiped away almost all of Hawaii’s East Island.

A majority of likely 2020 voters support key aspects of a Green New Deal even when faced with potential costs and downsides, but strict regulations to decarbonize the nation’s top polluters could trigger a backlash, according to a new poll from proponents of the policy. The survey, released by the think tank Data for Progress and shared with HuffPost, found net support for a range of policies, including improving drinking water infrastructure, reforesting land, providing job training and insurance to displaced workers, and guaranteeing clean-energy jobs.

University students should support “badass” teenagers who skip school to strike for climate action by walking out of lectures alongside them, a leading youth activist has said. In recent months more than 20,000 children have skipped school across Germany, Belgium, Switzerland and Australia, demanding governments and politicians do more to limit the effects of global warming. There are more strikes planned in the coming months.

The world is warming and ecosystems are dying. To avoid disastrous climatic change, massive reductions in CO2 emissions are required in all sectors, reaching net-zero globally no later than 2050. This requires an unprecedented and rapid change in our ways of life. In this, the world of research is challenged for two reasons. First, researchers are the source of the increasing number of warnings about the state of our climate and biodiversity, and their credibility would be damaged by not setting an example.

A planned protest on Friday will see schoolchildren across the UK walk out of their lessons to demand action over climate change. We have been to meet some of the teenagers looking to take control of their futures. Every Friday morning, 13-year-old Holly Gillibrand, from Fort William, skips school for an hour. She says the "sacrifice", as she describes it, is "a small price to pay for standing up for our planet". "If you get a detention, that's nothing to how we will suffer in future if nothing is done," she tells the BBC's Victoria Derbyshire programme.

Climate-related disasters have cost the world $650 billion over the last three years, and North America is shouldering most of the burden, according to a new report from Morgan Stanley. While governments and corporations are taking steps to mitigate the impacts of climate change, Morgan Stanley says private enterprises need to strongly consider preparing for a world gripped by more frequent and intense weather events, rising sea levels, changes to agriculture and the spread of infectious disease.
