Mark Lynas has spent decades pushing for action on climate emissions but now says nuclear war is even greater threat Climate breakdown is usually held up as the biggest, most urgent threat humans pose to the future of the planet today. But what if there was another, greater, human-made threat that could snuff out not only human civilisation, but practically the entire biosphere, in the blink of an eye?
f global warming reaches or exceeds two degrees Celsius by 2100, University of Western Ontario's Joshua Pearce says it is likely that mainly richer humans will be responsible for the death of roughly one billion mainly poorer humans over the next century. The oil and gas industry, which includes many of the most profitable and powerful businesses in the world, is directly and indirectly responsible for more than 40% of carbon emissions—impacting the lives of billions of people, many living in the world's most remote and low-resourced communities. A new study proposes aggressive energy policies that would enable immediate and substantive decreases to carbon emissions and recommends a heightened level of government, corporate and citizen action to accelerate the decarbonization of the global economy, aiming to minimize the number of projected human deaths.
Only if there is a fundamental change in the way we manage land we can reach the targets of climate-change mitigation, avert the dramatic loss of biodiversity and make the global food system sustainable.
Three months before COP27, new research suggests the most ambitious climate pledges are also most credible.
Vital United Nations climate talks, billed as one of the last chances to stave off climate breakdown, will not produce the breakthrough needed to fulfil the aspiration of the Paris agreement, key players in the talks have conceded.
Growing global meat consumption threatens to derail the Paris Agreement, but that hasn’t stopped the meat industry insisting it is part of the solution to climate change.
For the last three decades, environmental groups have diligently lobbied their governments to slow carbon and methane emissions. Activists have put pressure on industry too. They’ve been smart, full of energy and creative. Yet, despite several big international treaties — especially the Kyoto Protocol and the Paris Agreement — and some impressive accomplishments including holding up pipelines and getting institutional investors to divest from fossil fuels, the pollution and the warming have not stopped.
