Economic assumptions about risks of the climate crisis are no longer relevant, says the communications expert Genevieve Guenther

Despite mounting evidence of global warming’s costs, the Trump administration has made multiple moves to avoid tracking climate-related economics.

A Dartmouth College research team came up with the estimated pollution caused by 111 companies, with more than half of the total dollar figure coming from 10 fossil fuel providers: Saudi Aramco, Gazprom, Chevron, ExxonMobil, BP, Shell, National Iranian Oil Co., Pemex, Coal India and the British Coal Corporation. For comparison, $28 trillion is a shade less than the sum of all goods and services produced in the United States last year.

A new report from U.K. actuaries and climate scientists "shows a 50% GDP contraction between 2070 and 2090 unless an alternative course is chartered," said the lead author.​

The economic damage wrought by climate change is six times worse than previously thought, with global heating set to shrink wealth at a rate consistent with the level of financial losses of a continuing permanent war, research has found. A 1C increase in global temperature leads to a 12% decline in world gross domestic product (GDP), the researchers found, a far higher estimate than that of previous analyses.

As Malm and Carton explain, if firm policies were put in place to “leave fossil fuels in the ground”, stranding the assets of fossil fuel companies, there would be “layer upon layer” of value destruction.

he global economy could face 50% loss in gross domestic product (GDP) between 2070 and 2090 from the catastrophic shocks of climate change unless immediate action by political leaders is taken to decarbonise and restore nature, according to a new report The stark warning from risk management experts the Institute and Faculty of Actuaries (IFoA) hugely increases the estimate of risk to global economic wellbeing from climate change impacts such as fires, flooding, droughts, temperature rises and nature breakdown.

Climatenomics lays out how ‘supply chain disruptions’ has become a euphemism for the effects of climate change

Many economic assessments of the climate crisis “grossly undervalue the lives of young people and future generations”, Prof Nicholas Stern warned on Tuesday, before the Cop26 climate summit in Glasgow.

Country hopes to ensure effects of climate crisis are always considered in business, investment, lending and insurance decisions

We also asked about organisations’ risk response and approaches to planning. Our survey results support a picture of UK organisations that are taking steps to prepare for similar extreme weather, with the top three actions of organisations affected being capacity training or some form of knowledge transfer, investment in new technologies, and making an insurance claim. While just 16% of organisations reported having an adaptation plan, a considerable proportion (37%) said their organisation was planning to develop one.

As an economist who has studied the effects of weather and climate change, I have examined a large body of work that links heat to economic outcomes. Here are four ways extreme heat hurts the economy – and a little good news.

Consumers are faced with "confusing and often misleading claims about sustainability benefits", according to US vice president's analysis.

New research suggests social transformations that prompt “degrowth” could cut humanity’s climate footprint in time to meet the Paris climate agreement target.

Action on climate change is arguably the greatest challenge for public policy of our times. But despite economic forces being the major driver of the carbon dioxide problem, this column argues that economists have so far been too silent on the subject. For example, the Quarterly Journal of Economics, the most-cited journal in economics, has never published an article on climate change. Good economics can and should play a fundamental role in guiding the policy framework that will influence investment decisions in the coming years, so it is important that the profession dramatically increases its work now.
