Best way to fight climate change? Plant a trillion trees

This is by far — by thousands of times — the cheapest climate change solution, study co-author says

The most effective way to fight global warming is to plant lots of trees, a trillion of them, maybe more, according to a new study.

Canada’s economy would be less hurt by climate change than other countries, Moody’s says

Consulting firm says climate change will come with winners and losers, economically speaking

In a new report, Moody’s tried to assess the economic impacts that would entail if some of the more dire predictions of climate change come to pass in the coming decades. The report is based on the extensive report that the Nobel Prize-winning Intergovernmental Panel on Climate Change put out last fall, in which the UN agency laid out a number of dire predictions for what may be in store for the planet’s climate in the years to come.

The main takeaway of that report is that it is basically already too late to hold the global temperature rise to just one degree Celsius — and concludes much bigger temperature rises are quickly becoming more likely, if not inevitable.

The IPCC report concluded that the economic impact of a two-degree rise in global temperature could be as much as $69 trillion US, and even limiting the rise to 1.5 degrees would come with a $54-trillion price tag.

The Moody’s report took a deeper dive into those scenarios, and tried to break down how different parts of the planet would see their economies impacted by a hotter climate. Broadly, the Moody’s report breaks the impact of a hotter planet into six areas:Rising sea levels. 

-Human health effects.

-Heat effect on labour productivity.

-Impact on crop yields and agriculture.


-Energy demand.

Climate change lawsuits spreading around the world, says report

Legal action on climate change has become a global phenomenon, with lawsuits launched against governments and corporate interests in 28 countries so far, according to new research published Thursday.

A report from the Grantham Research Institute at the London School of Economics and Political Science looked at instances of legal action on climate change from 1990 to May 2019.

Researchers found that while the US remains the global leader in terms of climate change litigation, the prevalence of such lawsuits has spread worldwide, according to a press release.

This reflects an increasing willingness to use litigation as a tool to influence policy, according to the report, and human rights and science are playing an increasingly important role in these lawsuits.

Since 2015, the first cases of climate change litigation were recorded in Colombia, Indonesia, Norway, Pakistan and South Africa, according to the report, titled “Global trends in climate change litigation: 2019 snapshot.”

“More and more countries, not only in the global north but in the global south, are bringing cases,” report co-author Joana Setzer, research fellow at the Grantham Research Institute on Climate Change and the Environment.”
