UN report places new emphasis on climate tipping points

Grist

The science is clear: Atmospheric carbon dioxide is higher than it has been in 2 million years, the earth is hotter than it has been for at least 2,000 years, and sea levels are rising faster than in the last 3,000 years. Globally, permafrost stores almost twice the carbon that is currently in the atmosphere.

IPCC report: The 10 key conclusions

Business Green

Perhaps most worrying of all, impacts such as sea level rise, ocean acidification, and permafrost melt are now inevitable and near-irreversible within timespans stretching from hundreds to potentially thousands of years, leaving only their extent open to question. Natural carbon sinks become less effective as emissions rise.

Can the world overshoot its climate targets — and then fix it later?

Grist

“It will gain increasing importance as the herculean difficulty of reducing emissions to net zero and removing vast stores of carbon from the atmosphere become clearer.”. In the broadest sense, overshoot is a future where the world does not cut carbon quickly enough to limit global warming to 1.5 Climeworks.

Empty labs, abandoned research: Coronavirus puts climate science on hold

Grist

Bristol is studying samples of soil and ice extracted from the north Alaskan coast in 2018. Bristol is trying to understand how much of that carbon stored in the melting permafrost makes its way into the sea, and eventually, into the atmosphere, where it will help heat up the planet.

Want to prevent California’s looming flood disaster? Grow a marsh.

Grist

As they walled off rivers and created dry islands from what was previously soggy marsh, they discovered incredibly rich soil. No one foresaw that this very bounty — soil rich with organic material — would, over time, become a curse of sorts. That organic material contains copious amounts of carbon.

'Every fraction of warming matters': World careering towards irreversible climate impacts, top scientists warn

Business Green

As a result, climate change is already affecting every inhabited region on Earth, and impacts such as sea level rise, ocean acidification, and permafrost melt are inevitable and near-irreversible, leaving only their extent open to question.

Understanding the Anthropocene, Resilience Thinking, and the Future of Industry

Green Business Bureau

Eras in the Earth’s history are defined by major climactic events and distinguished through the fossil record, carbon dating, and other methods. Nitrogen and phosphorous are both essential for plant growth, thus they are made into fertilizers that pollute waterways and coastal zones, and accumulate in the world’s soil and land.
