Could carbon-capture technology be a silver bullet to stop climate change

Few companies specialize in carbon removal and the tools they produce are currently still expensive — Peter Fiekowsky, a physicist and entrepreneur, hates silver bullets. But at a climate summit in California last month he found himself pitching one. In partnership with the company Blue Planet, he was demonstrating a low-tech-looking machine that can pull …

Analysis: Why the IPCC 1.5°C report expanded the carbon budget

Greenhouse gas emissions from human activity have already raised global temperatures by around 1°C since pre-industrial times. This leaves a rapidly shrinking “carbon budget” to stay within the aspirational 1.5°C of the Paris Agreement on climate change — This budget is a simplified way to measure the additional emissions that can enter the atmosphere to …

We must reduce greenhouse gas emissions to net zero or face more floods

The world heating up by even 1.5°C would have a brutal impact on future generations — The authoritative new report by the Intergovernmental Panel on Climate Change sets the world a clear target: we must reduce emissions of greenhouse gases to net zero by the middle of this century to have a reasonable chance of …

Q&A: How ‘integrated assessment models’ are used to study climate change

Working out the best ways to tackle climate change is one of the key challenges facing policymakers both today and in the decades ahead — To inform these decisions, scientists and economists have developed a suite of tools known as “integrated assessment models” (IAMs). These models are used to answer central questions about climate change, …

California plans to show the world how to meet the Paris climate target

Governor Jerry Brown signed an executive order for statewide carbon neutrality by 2045 — Last week, California Governor Jerry Brown signed State Senator and US Senate candidate Kevin de León’s SB 100, which mandates that the state obtain all of its electricity from zero-carbon sources by 2045. That in itself was a big deal, but …

‘Worrying trend’ in UK emission cuts beyond power and waste, says CCC

Progress in cutting greenhouse gas emissions from the power and waste sectors has “masked the failures in other areas”, says the government’s official climate advisors — The latest annual progress report from the Committee on Climate Change (CCC), published today, says the UK now faces a much tougher challenge to tackle these other sectors, in …

Climate change to become ‘greatest pressure on biodiversity’ by 2070

The combined effects of global warming and land-use change could cause the world’s ecosystems to lose more than a third of their animal species by 2070, a new study finds — Climate change is expected to become the largest driver of biodiversity loss by the second half of the century, the research finds, surpassing the …

World can ‘safely’ store billions of tonnes of CO2 underground

Storing billions of tonnes of CO2 underground would be a “safe and effective” way to help limit the effects of climate change, a new study says — The research suggests that large amounts of CO2 could be stored under the ground or sea with only a small risk of surface leakage in the following 10,000 …
