Sur les réseaux sociaux, les comptes qui proposent à leurs abonnés de suivre en ligne les trajets des jets privés des milliardaires sont de plus en plus populaires. Une façon de mettre la pression sur ces grands patrons ou stars de la pop, sommés de revoir à la baisse leur train de vie et le bilan carbone qui l'accompagne.
The focus of the opening day of the 17th session of the United Nations Forum on Forests (UNFF17) was a High-Level Roundtable on the UNFF response to, role in, and expectations from forest-related multilateral developments. Members of the Forum also started providing updates on their actions in support of the three UNFF thematic priorities for 2021-2022; these will continue on Tuesday.
Strong measures by Europe could quickly deprive Russia of oil and gas income worth billions, experts say
Politician says droughts and climate-induced famine in the country are a result of the behaviours of rich nations
Researchers examined the economic cost of the climate crisis and found it would cut about 37% from global GDP this century, more than twice the drop experienced in the Great Depression. For every tonne of carbon dioxide emitted, the global economy would be $3,000 worse off by the end of the century, they estimated.
LEDs used in streetlights typically emit white light, while sodium lamps have a characteristic yellow glow – as seen in the picture below. This change in the colour of artificial light is predicted to have major consequences for wildlife.
‘Eco-friendly’ lights found to be worse than sodium ones – but both contribute to insect decline, says study
Quelle est donc cette folie qui consiste à mettre sur le marché des engins électriques ou hybrides rechargeables de plus de 2 tonnes dont la puissance délirante sert au mieux à mouvoir cette masse, au pire ne sert… à rien dans un contexte de zones 30 qui se généralisent?
Depuis, plusieurs méthodes ont été testées pour restaurer les écosystèmes dans la zone. L’une d’entre elles est fondée sur l’introduction de fourmis moissonneuses dans les sols contaminés.
The spread of electrical lighting is blocking out the stars and threatens the health of many species … including humans. Now our national parks plan to take back the night
Light pollution is a significant but overlooked driver of the rapid decline of insect populations, according to the most comprehensive review of the scientific evidence to date.Artificial light at night can affect every aspect of insects’ lives, the researchers said, from luring moths to their deaths around bulbs, to spotlighting insect prey for rats and toads, to obscuring the mating signals of fireflies.
Freshwater availability is changing worldwide. Here we quantify 34 trends in terrestrial water storage observed by the Gravity Recovery and Climate Experiment (GRACE) satellites during 2002–2016 and categorize their drivers as natural interannual variability, unsustainable groundwater consumption, climate change or combinations thereof. Several of these trends had been lacking thorough investigation and attribution, including massive changes in northwestern China and the Okavango Delta. Others are consistent with climate model predictions. This observation-based assessment of how the world’s water landscape is responding to human impacts and climate variations provides a blueprint for evaluating and predicting emerging threats to water and food security. Analysis of 2002–2016 GRACE satellite observations of terrestrial water storage reveals substantial changes in freshwater resources globally, which are driven by natural and anthropogenic climate variability and human activities.
Light pollution conceals true darkness from 80% of Europe and North America. What do we lose when we can no longer see the stars?
