Transatlantic collaboration aims to boost resilience of sea walls

Envirotec Magazine

Around 148 million people worldwide are exposed to coastal flooding events, which are predicted to surge in frequency and severity in the coming decades as climate change drives sea levels higher. It’s hoped this will highlight areas where the design and resilience of sea walls could be strengthened.

Earth is getting extra salty, an ‘existential threat’ to freshwater supplies

Grist

billion acres of soil around the world have gotten saltier, an area roughly the size of the entire United States, and it’s stressing out plants. Salt is even getting kicked up into the air: In arid regions, “lakes are drying up and sending plumes of saline dust into the atmosphere,” such as the Aral Sea in Central Asia, the study says.

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. In the two long weeks since the World Health Organization declared COVID-19 a pandemic, research into our warming climate has been put on hold. Emily Bristol takes soil samples off the coast of Alaska. Bristol is one of the lucky ones.

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.

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. And the land began to sink.

'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.
