The twenty-first century was marked by a number of extreme weather events over northern continents. Amplified warming in the Arctic region and associated changes in atmospheric dynamics may provide a clue for understanding the origin of these recent extremes.
Firmly establishing Earth's surface temperatures during a sustained episode of global warming in the Pliocene will help 'ground truth' projections of future climate based on computer simulations using global climate models.
Glacial meltwater contributions to rivers are declining in many parts of the world, but the effect of these changes on river communities remains poorly understood. Now a quantitative analysis points to the potential scale of this biodiversity problem.
As the evidence for a tight link between greenhouse-gas emissions and climate change accrues, scientists — and editors — should moderate their use of international air travel.
Development expert Barbara Harriss-White leads a team of specialists from agriculture to economics, environmental science and policy to investigate neglected aspects of the climate change response in India.
China, the world's largest emitter of greenhouse gases, is developing seven experimental carbon-trading schemes. Anna Petherick looks for clues as to how that's going.
Substantial work has shown the potential energy and climate benefits of full battery electric vehicles (BEVs) — an important policy option to mitigate climate change — but there are still uncertainties about their market diffusion. Research shows the importance of assessing BEV diffusion from an integrated perspective, focusing on the interaction between technology and behaviour.
The newly observed economic phenomenon carbon-market intelligence was worth over £35 billion in 2010–2011 and is forecast to experience annual double-digit growth over the next five years.
Teaching the science of climate change has become a political issue in many schools across the United States. Nature Climate Change look at an education battle against denialists.
Tackling greenhouse-gas emissions from aircraft was never going to be easy, but Europe is laying the groundwork. Sonja van Renssen investigates whether the plans have wings.
Several factors can either increase or buffer the effects of climate change on the volatility of grain prices. A study shows that US corn price volatility is more sensitive to near-term climate change than to energy policy or agriculture–energy market integration. A biofuels mandate increases price sensitivity to climate change by more than 50%.
Kevin Anderson, Deputy Director of the UK Tyndall Centre and an expert on greenhouse-gas emissions trajectories explains to Nature Climate Change why he believes that carbon offsetting can be worse than useless.
The 2010 Cancún Agreement established a financial mechanism, through the Green Climate Fund, to support developing countries in greenhouse-gas emissions abatement. However, the different countries’ financial needs are often assessed on the basis of top-down cost estimates of energy technologies. Now a study provides a more fine-grained bottom-up approach that highlights the need for a ‘fair’ baseline calculation methodology and calls for a phase-out of fuel subsidies.
