CLICK HERE - The Global Risks Report 2019

weforum.org - January 15, 2019

The Global Risks Report 2019 is published against a backdrop of worrying geopolitical and geo-economic tensions. If unresolved, these tensions will hinder the world’s ability to deal with a growing range of collective challenges, from the mounting evidence of environmental degradation to the increasing disruptions of the Fourth Industrial Revolution.

The report presents the results of our latest Global Risks Perception Survey, in which nearly 1,000 decision-makers from the public sector, private sector, academia and civil society assess the risks facing the world. Nine out of 10 respondents expect worsening economic and political confrontations between major powers this year. Over a ten-year horizon, extreme weather and climate-change policy failures are seen as the gravest threats.

Scientists warn policymakers not to ignore links, and stress that ‘every action counts’

Policymakers have severely underestimated the risks of ecological tipping points, according to a study that shows 45% of all potential environmental collapses are interrelated and could amplify one another.

The authors said their paper, published in the journal Science, highlights how overstressed and overlapping natural systems are combining to throw up a growing number of unwelcome surprises . . .

 . . . Until recently, the study of tipping points was controversial, but it is increasingly accepted as an explanation for climate changes that are happening with more speed and ferocity than earlier computer models predicted.

Bank of America Corp. worries flooded homeowners will default on their mortgages. The Walt Disney Co. is concerned its theme parks will get too hot for vacationers, while AT&T Inc. fears hurricanes and wildfires may knock out its cell towers.

The Coca-Cola Co. wonders if there will still be enough water to make Coke.

As the Trump administration rolls back rules meant to curb global warming, new disclosures show that the country’s largest companies are already bracing for its effects. The documents reveal how widely climate change is expected to cascade through the economy -- disrupting supply chains, disabling operations and driving away customers, but also offering new ways to make money.

The faster the ocean warms, the faster key Antarctic glaciers will disintegrate.

A stunning new study on Antarctic sea ice collapse greatly raises the risk of a 10-foot sea level rise this century if President Donald Trump’s climate policies aren’t quickly reversed.

Warming ocean waters drove a 6-fold increase in annual ice mass loss from the Antarctic ice sheet between 1979 and 2017, according to a new study in the Proceedings of the National Academy of Sciences.

It’s been known for a while that the West Antarctic Ice Sheet (WAIS) was unstable and collapsing at an accelerating rate due to global warming. But the new study finds that parts of the vastly larger East Antarctic Ice Sheet (EAIS) are also disintegrating.
