The application of a new metric of seasonal onset over Europe to existing observational data sets indicates that the start of summer has advanced significantly over recent decades, a trend expected to continue under global warming.
An analysis of climate change mitigation policies in an idealized integrated assessment framework highlights the importance of economic growth, and investment in technologies such as large-scale carbon dioxide removal, to limit peak warming.
Modelling shows that twenty-first-century climate change could significantly affect the market value of global financial assets, and suggests that limiting warming to no more than 2 °C would make financial sense to many investors.
An analysis of preliminary official statistics shows that, rather than falling as claimed, coal-derived energy consumption in China stayed flat in 2014, while fossil CO2 emissions probably increased slightly, with a decrease expected for 2015.
Reducing deforestation and forest degradation offers a quick win for climate mitigation. Using satellite data we are now able to better constrain pantropical estimates of forest loss, reshaping our understanding of the annual to decadal variability in land sources and sinks in the global carbon cycle.
A high-impact weather event that occurred at the end of a decade of weather extremes led to the emergence of extreme event attribution science. The challenge is now to move on to assessing the actual risks, rather than simply attributing meteorological variables to climate change.
The recent slowdown in global warming challenged our understanding of climate dynamics and anthropogenic forcing. An early study gave insight to the mechanisms behind the warming slowdown and highlighted the ocean's role in regulating global temperature.
Understanding the potential social and economic damage and loss wrought by tropical cyclones requires not only understanding how they will change in frequency and intensity in a future climate, but also how these hazards will interact with the changing exposures and vulnerabilities associated with social change.
Insurance is gaining importance in and beyond the climate negotiations and offers many opportunities to improve climate risk management in developing countries. However, some caution is needed, if current momentum is to lead to genuine progress in making the most vulnerable more resilient to climate change.
Climate researchers and educators must recognize legitimate disagreements about the risks of climate change, and should support informed dialogue about value-laden choices.
The past five years have been an interesting time for the climate and for climate policy. But how has climate science evolved since Nature Climate Change first launched?
Indigenous knowledge and experience have historically been under-represented in the IPCC's reports. New guidelines, policies and more nuanced content are needed to develop culturally relevant and appropriate adaptation policies.
When setting carbon prices in a warming world, policymakers must be cognizant of the potential economic and environmental consequences of the risk of multiple, interrelated catastrophes.
