The extent to which distant populations fluctuate similarly has significant ecological consequences, but can be difficult to investigate. Now research reveals the drivers of phenological synchrony for aphid pest species across the United Kingdom.

Incorporating temperature acclimation of photosynthesis and foliar respiration into Earth system models improves their ability to reproduce observed net ecosystem exchange of CO₂, and reduces the temperature sensitivity of terrestrial carbon …

Arctic temperatures are most sensitive to emissions of short-lived climate forcers from a small number of Arctic nations (Russia and Nordic countries) that are also the most impacted by this warming, easing the implementation of mitigation …

An application of network science reveals the institutional and corporate structure of the climate change counter-movement in the United States, while computational text analysis shows its influence in the news media and within political circles.

Rapid growth in global CO₂ emissions from fossil fuels and industry ceased in the past two years, despite continued economic growth. Decreased coal use in China was largely responsible, coupled with slower global growth in petroleum and faster …

Policymakers have committed to tackling loss and damage as a result of climate change across three high-profile international processes. Framing post-2015 development as a means to address loss and damage can synergize these agendas.

Tropical forests could offset much of the carbon released from the declining use of fossil fuels, helping to stabilize and then reduce atmospheric CO₂ concentrations, thereby providing a bridge to a low-fossil-fuel future.

The scarcity of robust scientific evidence supporting the attribution of observed impacts to climate change in some vulnerable regions does not indicate that no such impacts have occurred.

Climate models include many processes that may be simplified to save computational time. This work shows that model representation of upper atmosphere ozone can impact on the projected climate sensitivity.

Greenhouse-gas emissions are likely to have an impact on the damage caused by extreme weather events, such as tropical cyclones. A study predicts that climate change will increase the frequency of these high-intensity storms in selected ocean basins …

Regional climate models for the Persian (Arabian) Gulf indicate that extremes of wet-bulb temperature—a measure of temperature and humidity—may exceed a critical threshold for human tolerance with implications for the future human habitability of …
