Industrialized economies are increasingly turning their backs on aid and diplomacy to build up their armies.

But analysts fear that hostile and unreliable states like Russia, China and Turkey will step in to fill the gap.

Agreed. See our recent piece showing how global freshwater reserves have significantly declined over the past two decades, leading to the emergence of mega-drying regions.

However, while the aggregate effect is expected to be small, countries need to prepare for significant sectoral and regional shifts. The report highlights measures to reduce five frictions that prevent workers to adjust to a rapidly changing labor market: skills, space, time, norms, and wages.

At the same time, the shift to low-emission development pathways, with emissions reduced by 71 percent by 2050, would have a small and most of the time positive impacts on GDP and labor income.

Key highlights include that climate adaptation could yield labor income benefits equivalent to 150 million jobs by 2050, a combination of new jobs created by investments in infrastructure or nature-based solution and jobs that are protected from negative shocks and impacts.

The 4th “Country Climate and Development Report” summary is out, covering 93 economies, with a focus on jobs.

This report is unique in that it is
based on dozens of individual-country reports, each prepared (and reviewed) individually.

Thanks to renewable power expansion, fuel-importing countries saved more than $1.3tn between 2010 and 2023 that would otherwise have been spent on fossil fuels from overseas. Important contribution from @iea.org to current debates!

Une terrible nouvelle! Personnellement il me semble que ça va contre le “sens de l’Histoire”.

Encore plus personnellement je vais amèrement regretter cette ligne dans mes transits réguliers entre l’Ukraine et la France (en train c’est top)

Ouf: Reste le train de nuit Vienne-Bruxelles

How do we estimate climate change macroeconomic risks in The World Bank's Country Climate and Development Reports? We just published a methodological paper that presents a methodology used in many of them, with our partners at Industrial Economics (IEc). documents1.worldbank.org/curated/en/0...

Firm-Level Climate Change Adaptation : Micro Evidence from 134 Nations Are firms adapting to climate change? This paper studies this question by combining geocoded World Bank Enterprise Survey data with spatially granular weather data to .

From WB colleagues, an assessment of firm-level vulnerability and adaptation. Based on 160,000 firms, they find they small and medium-size firms in low- and low-middle income countries see revenues decline by 12% when temperatures are 0.5◦C above average. documents.worldbank.org/en/publicati...

CCDRs now cover 72 economies, each with its own modeling, and their preparation include the iterative aspects mentioned in the paper, both across disciplines (eg energy and macro) and btw modelers and decision makers.
