Climatologie actuelle, un (petit) pas vers plus de réalisme ?

by SCE-INFO, 7 février 2020 in ScienceClimatEnergie

Nature, l’une des plus célèbres revues scientifiques à l’échelle mondiale, vient de publier un article assez inattendu. Celui-ci se permet une analyse critique des scénarios climatiques proposés dans les rapports du GIEC (scénarios RCP, i.e. “Representative Concentration Pathways”). Comme on peut le constater chaque jour en consultant les médias, ce sont toujours les scénarios les plus catastrophiques qui sont relayés.

Economic impact of energy consumption change caused by global warming

by P. Lange & K. Gregory, February 8, 2020 in ClimateEtc.

A new paper ‘Economic impact of energy consumption change caused by global warming’ finds global warming may be beneficial.

In this blog post we reproduce the Abstract, Policy Implications and Conclusions and parts of the Introduction, Results and Discussion. We encourage you to read the entire paper.

Abstract: This paper tests the validity of the FUND model’s energy impact functions, and the hypothesis that global warming of 2 °C or more above pre-industrial times would negatively impact the global economy. Empirical data of energy expenditure and average temperatures of the US states and census divisions are compared with projections using the energy impact functions with non-temperature drivers held constant at their 2010 values. The empirical data indicates that energy expenditure decreases as temperatures increase, suggesting that global warming, by itself, may reduce US energy expenditure and thereby have a positive impact on US economic growth. These findings are then compared with FUND energy impact projections for the world at 3 °C of global warming from 2000. The comparisons suggest that warming, by itself, may reduce global energy consumption. If these findings are correct, and if FUND projections for the non-energy impact sectors are valid, 3 °C of global warming from 2000 would increase global economic growth. In this case, the hypothesis is false and policies to reduce global warming are detrimental to the global economy. We recommend the FUND energy impact functions be modified and recalibrated against best available empirical data. Our analysis and conclusions warrant further investigation.

Ukraine and Romania were two of the hardest hit Eastern European nations during last week’s extreme winter weather.

In Romania’s capital Bucharest, the severe blizzard has reportedly felled more than 100 trees — many falling onto roads and vehicles — while billboards, traffic lights, and “construction elements” were also toppled, according to the Bucharest-Ilfov Emergency Inspectorate.

450+ schools were closed across the country on Feb. 6 and 7 due to the heavy snowfall, and public transport was cancelled following an incident with a bus colliding with a tram in icy conditions.
