Mapped: Where Are the World's Most Sustainable Companies? For many people, the concept of a shorter workweek is enticing.

Mapped: Where Are the World's Most Sustainable Companies?

After all, it can be difficult to find enough time for the things we love. Is it reasonable then, in our quest for happiness, to begin working less?

Nucléaire. Why Renewables Can’t Save the Planet. When I was a boy, my parents would sometimes take my sister and me camping in the desert. A lot of people think deserts are empty, but my parents taught us to see the wildlife all around us, including hawks, eagles, and tortoises. After college, I moved to California to work on environmental campaigns. I helped save the state’s last ancient redwood forest and blocked a proposed radioactive waste repository set for the desert. In 2002, shortly after I turned 30, I decided I wanted to dedicate myself to addressing climate change. I was worried that global warming would end up destroying many of the natural environments that people had worked so hard to protect. The argument over plant learning and memory. Monica Gagliano studies learning and memory in plants.

The argument over plant learning and memory

She's an “evolutionary ecologist" who performs behavioral experiments on plants that are adapted from studies of animal intelligence. Her work has convinced her that plants learn and have memories. Gagliano's been cited in The New Yorker, and she spoke recently to radiolab. Her peer-reviewed conclusions are at times controversial, though specific criticisms of her methodologies have been sparse. Openness to Experience linked to reduced cortical thickness in several brain regions. Individual differences in the personality trait Openness to Experience are associated with variation in brain structure, according to new neuroimaging research.

The findings, published in the journal Human Brain Mapping, shed new light on the neural basis of creativity. The magnetic resonance imaging study found Openness to Experience correlated with reduced cortical thickness in several brain regions. “Historically, one of the most robust findings in the literature on creativity is that there is a relationship between personality and creativity,” said study author Oshin Vartanian of the University of Toronto and Defence Research and Development Canada. “More recently, researchers in the field of personality neuroscience have begun to explore regions of the brain that are related to variations in different personality factors—one of which is openness to experience. The study — like all research — includes some limitations. Global warming may be twice what climate models predict. A new study based on evidence from past warm periods suggests global warming may be double what is forecast.

Global warming may be twice what climate models predict

Future global warming may eventually be twice as warm as projected by climate models and sea levels may rise six metres or more even if the world meets the 2°C target, according to an international team of researchers from 17 countries. The findings published last week in Nature Geoscience are based on observational evidence from three warm periods over the past 3.5 million years when the world was 0.5°C-2°C warmer than the pre-industrial temperatures of the 19th Century. The research also revealed how large areas of the polar ice caps could collapse and significant changes to ecosystems could see the Sahara Desert become green and the edges of tropical forests turn into fire dominated savanna. "This suggests the carbon budget to avoid 2°C of global warming may be far smaller than estimated, leaving very little margin for error to meet the Paris targets.

Elle vise à augmenter la fertilité des sols en couvrant la terre le plus possible et en abandonnant le labour. Frédéric Thomas, agriculteur spécialiste des techniques sans labour et fondateur de la revue TCS (Techniques Culturales Simplifiées), analyse les débats qui agitent cette agriculture. En quoi l’agriculture de conservation est-elle, comme vous l’affirmez, une « troisième voie » entre bio et conventionnel ?

La France creuse la « dette écologique » A compter du 5 mai, si le monde entier vivait comme les Français, les ressources naturelles que la planète peut renouveler en un an seraient consommées.

La France creuse la « dette écologique »

La France a commencé à réduire son déficit budgétaire, mais son déficit écologique, lui, continue de se creuser inexorablement. C’est l’alerte que lance le WWF, dans un rapport publié vendredi 4 mai. A compter de samedi, les Français vivront en quelque sorte à crédit : si leur niveau de consommation était généralisé sur la planète, l’ensemble des ressources que la nature peut renouveler en un an serait d’ores et déjà épuisé. Le sable, une ressource en voie d’épuisement. C’est maintenant que tout se joue… Le désastre environnemental s’accélère et s’aggrave, les citoyens sont de plus en plus concernés, et pourtant, le sujet reste secondaire dans le paysage médiatique.

Fifty years ago, on April 4, 1968, Martin Luther King Jr. was assassinated in Memphis, Tennessee.

The Arctic may have ice-free summers if Paris climate goals are exceeded a half-degree

The murder of the civil-rights advocate at age 39 rocked a country where memories of the slayings of John F. Kennedy and Malcolm X remained fresh. And just months later, Robert F. Kennedy would be gunned down in Los Angeles. King’s murder fueled decades of conspiracy theories and allegations of a government coverup from those who believe James Earl Ray, the man who initially confessed, couldn’t have acted alone. Five decades later, according to some of those closest to the case—including King’s own family—the question of exactly what happened on the second-floor balcony of the Lorraine Motel that April 4 has still not been definitively answered.

The world needs to build 2 billion new homes over the next 80 years

According to the UN, the global population is set to reach over 11.2 billion by the year 2100, up from the current population which was estimated at the end of 2017 to be 7.6 billion. And that is considered to be “medium growth”. The upscaling required in terms of infrastructure and development, not to mention the pressure on material resources, is equivalent to supplying seven times the population of the (pre-Brexit) European Union countries, currently 511m.
