Trump’s dictator-like behaviour is so brazen, so blatant, that paradoxically, we discount it. But now it’s time to call it what it is
A new point in history has been reached, entomologists say, as climate-led species’ collapse moves up the food chain even in supposedly protected regions free of pesticides
When attempting to quantify future harms caused by carbon emissions and to set appropriate energy policies, it has been argued that the most important metric is the number of human deaths caused by climate change. Several studies have attempted to overcome the uncertainties associated with such forecasting. In this article, approaches to estimating future human death tolls from climate change relevant at any scale or location are compared and synthesized, and implications for energy policy are considered. Several studies are consistent with the “1000-ton rule,” according to which a future person is killed every time 1000 tons of fossil carbon are burned (order-of-magnitude estimate). If warming reaches or exceeds 2 °C this century, mainly richer humans will be responsible for killing roughly 1 billion mainly poorer humans through anthropogenic global warming, which is comparable with involuntary or negligent manslaughter. On this basis, relatively aggressive energy policies are summarized that would enable im
The sixth assessment report of the IPCC assessed that the Arctic is projected to be on average practically ice-free in September near mid-century under intermediate and high greenhouse gas emissions scenarios, though not under low emissions scenarios, based on simulations from the latest generation Coupled Model Intercomparison Project Phase 6 (CMIP6) models. Here we show, using an attribution analysis approach, that a dominant influence of greenhouse gas increases on Arctic sea ice area is detectable in three observational datasets in all months of the year, but is on average underestimated by CMIP6 models. By scaling models’ sea ice response to greenhouse gases to best match the observed trend in an approach validated in an imperfect model test, we project an ice-free Arctic in September under all scenarios considered. These results emphasize the profound impacts of greenhouse gas emissions on the Arctic, and demonstrate the importance of planning for and adapting to a seasonally ice-free Arctic in the near
The collapse of modern societies has already begun. That is the conclusion of two years of research by the interdisciplinary team behind Breaking Together. How did it come to this? Because monetary systems caused us to harm each other and nature to such an extent it broke the foundations of our societies. So what can we do? This book describes people allowing the full pain of our predicament to liberate them into living more courageously and creatively.
Governments are ignoring calls to stop fossil fuel expansion—despite there being little time left to avoid the worst effects of global warming.
Dozens of people have been imprisoned, as changes in the law are used to curb protest. Is it part of a turn towards a more authoritarian state?
It is vital Moscow understands that escalation will not be risk-free, and expects a proportionate response
The frightful noise of gunfire, bombing and children’s screams in the cities of Ukraine reverberates across Europe. The full-scale Russian invasion launched last week is an unprovoked, heinous crime perpetrated against Ukraine’s citizens, their sovereign democratic state and all the free peoples of the world. The 24th of February is a day that will live in infamy. It will not be forgiven. It will surely never be forgotten.
A team of experts led by University College London researchers created a mathematical model for car use within a city, which has demonstrated that cities of the future must become fully car-free in order to remain liveable.
