How Roman priests walked through the “Gates to Hell” — and came back

Modern science explains how an ancient ritual worked.

Every other summer expected to break heat records by 2030

By 2050, virtually every summer will be hotter than anything we’ve experienced to date.

After three flat-line years, global carbon emissions are back on the rise

A sign that far more ambitious action is required in order to avoid runaway climate change.

There hasn’t been this much CO2 in the air in 3 million years. We have to stop, UN warns


Do volcanoes really emit more CO2 than humans?

Volcanoes emit a significant amount of carbon dioxide into the atmosphere, but nowhere near what humans emit.

Coal formation sucked so much CO2 out of the atmosphere that Earth nearly froze over 300 million years ago

“It is quite an irony that forming the coal that today is a major factor for dangerous global warming once almost lead to global glaciation,” the author said.

Trump Forest wants to compensate for the POTUS’ climate policy by planting 100 new billion trees

Nope, it’s not Trump’s idea.

Scientists call out Pruitt’s false view of climate change

These “alternative facts” go against 150 years of research.

The forests won’t fix our CO2 problem — in fact, they’ll scrub less than we assumed

Humanity gives with one hand and takes with the other. We just take a lot more than we give.

Scientists are trapping more and more CO2 into volcanic basalt

Storing CO2 underground might be one pivotal for our climate future.

Cheap catalyst reverses combustion and turns CO2 into ethanol fuel

And its discovery happened by accident, too.

‘We won’t ever see a month below 400ppm,’ said NASA’s chief climate scientist

We’ll have some explaining to do when our kids grow up.

Global warming causes plants and soils to ‘burp’ more CO2

A long-standing assumption that as the planet warms, the biosphere releases more CO2 in a positive feedback loop was confirmed by researchers.

Fastest global emissions rate ever means CO2 levels will never fall below 400ppm in our lifetimes

2016 will go in history as the first year carbon emission stay above 400ppm all year round. I don’t think anyone’s proud about this.

Vegetation on the planet grew by twice the size of mainland USA due to rising CO2 levels

As CO2 builds up in the atmosphere, this warms the planet, acidifies the ocean and melts glaciers. It also promotes plant growth — after all, that’s why it’s called the “greenhouse gas effect”. A huge collaborative effort spanning 32 authors from 24 institutions in eight countries found that in the last 33 years the area occupied by vegetation has significantly increased.

Trees trade carbon through their roots, using symbiotic fungi networks

A forest’s trees capture carbon not only for themselves, but also engage in an active “trade” of sorts with their neighbors, a new study found. University of Basel botanists found that this process, conducted by symbiotic fungi in the forest’s soil, takes place even among trees of different species.

Renewable plastic made from CO2 and waste agriculture

Making bottles to meet America’s demand for bottled water uses more than 17 million barrels of oil annually, enough to fuel 1.3 million cars for a year. Instead of petroleum, Stanford researchers have found a creative way to make plastic for bottles sourced from CO2 and inedible plants like waste agriculture or grasses.

Up to Half of All Fish in the Ocean might get ‘Drunk’ on CO2 by 2100

CO2 interferes with neuroreceptors in the brain of fish, causing them to behave as if drunk. By 2100, fish in half of the world’s water might be intoxicated in this way.

NASA shows how much CO2 we really pump into the atmosphere

Carbon dioxide levels in the atmosphere have never been higher: the average global CO2 levels have reached the 400 parts per million (ppm) milestone in the spring of 2015, The World Meteorological Organization (WMO) announced in the first week of November. Secretary-General Michel Jarraud warns that it won’t be long before even higher levels of the gas become a “permanent reality.”

CO2 in the atmosphere heralds imminent food chain collapse — and it’s gonna start in the oceans

The first global analysis of how marine environments react to the ever-increasing levels of CO2 that humanity is pumping into the atmosphere does not bode well at all for tomorrow’s would-be fishers. Published today in the journal Proceedings of the National Academy of Sciences (PNAS), the work of the University of Adelaide’s marine ecologists states that the warming and expected ocean acidification is likely to produce a reduction in diversity and numbers of various key species that underpin marine ecosystems around the world.
