Enjeux de la transition écologique
Cet ouvrage, aux nombreuses illustrations, donne une vision transversale des changements environnementaux d'échelle mondiale que connaît notre planète aux limites finies. Son objectif est, en particulier, de faire comprendre les mécanismes et conséquences du réchauffement climatique et de l'érosion de la biodiversité ainsi que leurs relations avec nos modes de vie et de consommation. Pour l'essentiel, il reprend l'un des premiers enseignements nu…
Near-real-time monitoring of global CO2 emissions reveals the effects of the Covid-19 pandemic
The COVID-19 pandemic is impacting human activities, and in turn energy use and carbon dioxide (CO 2 ) emissions. Here we present daily estimates of country-level CO 2 emissions for different sectors based on near-real-time activity data. The key result is an abrupt 8.8% decrease in global CO 2 emissions (−1551 Mt CO 2 ) in the first half of 2020 compared to the same period in 2019. The magnitude of this decrease is larger than during previous ec…
Biofuel burning and human respiration bias on satellite estimates of fossil fuel CO 2 emissions
The satellites that have been designed to support the monitoring of fossil fuel CO 2 emissions aim to systematically measure atmospheric CO 2 plumes generated by intense emissions from large cities, power plants and industrial sites. These data can be assimilated into atmospheric transport models in order to estimate the corresponding emissions. However, plumes emitted by cities and powerplants contain not only fossil fuel CO 2 but also significa…
Evaluation of the WRF-UCM mesoscale model and ECMWF global operational forecasts over the Paris region in the prospect of tracer atmospheric transport modeling
The quantification of CO2 emissions from cities using atmospheric measurements requires accurate knowledge of the atmospheric transport. Complex urban terrains significantly modify surface roughness, augment surface energy budgets, and create heat islands, all of which lead to lower horizontal winds and enhanced convection over urban areas. The question remains whether these processes should be included in atmospheric transport models that are us…
Surface Urban Heat Island Across 419 Global Big Cities
Urban heat island is among the most evident aspects of human impacts on the earth system. Here we assess the diurnal and seasonal variation of surface urban heat island intensity (SUHII) defined as the surface temperature difference between urban area and suburban area measured from the MODIS. Differences in SUHII are analyzed across 419 global big cities, and we assess several potential biophysical and socio-economic driving factors. Across the …
