Climate and health impacts of US emissions reductions consistent with 2 °C
If the US were to implement power and transport policies consistent with a 2 °C scenario, it could prevent hundreds of thousands of premature deaths each year and be worth billions of dollars to the US economy.

An increase in aerosol burden and radiative effects in a warmer world
Modelling allows estimation of aerosol–climate feedbacks on the Earth’s radiative balance and suggests that climate change may increase aerosol burden and surface concentration, negatively affecting future air quality.

Future temperature in southwest Asia projected to exceed a threshold for human adaptability
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 the region.

From local perception to global perspective
Local weather influences perception of climate change. Although weather is not representative of climate, this study shows that the percentage of the population experiencing higher temperatures has increased, in line with climate model projections.

Impacts of temperature and its variability on mortality in New England
Modelling shows that although the impact of warmer summers and winters may cancel each other out, climate change could still have a significant impact on mortality rates in New England owing to changes in temperature variability.

All hail robocabs
Connected and automated vehicles enable new business models, such as self-driving taxis, that could transform transportation. These models have the potential to reduce energy consumption and greenhouse-gas emissions, but only if they are developed with energy use in mind.

Effects of climate change and seed dispersal on airborne ragweed pollen loads in Europe
Common ragweed is an invasive plant in Europe, and many people are allergic to its pollen. Modelling results indicate that airborne pollen concentrations are likely to increase in Europe over coming decades, at least in part owing to climate change.

Greenhouse-gas payback times for crop-based biofuels
Greenhouse-gas payback times are derived for biofuel production systems using five feedstocks under high- and low-input farm management to assess replacement of natural vegetation with crop-based biofuels. Estimates ranged from 1–162 years.

US power plant carbon standards and clean air and health co-benefits
Clean electricity generation is good for the climate and improves the quality of the air that we breathe. An analysis of US power plants shows that the magnitude of the resulting health benefits depends greatly on the carbon standards adopted.

Positive but variable sensitivity of August surface ozone to large-scale warming in the southeast United States
The sensitivity of surface ozone, a major pollutant, to climate warming is shown to be positive but variable over the southeast United States.

Increased frequency of extreme La Niña events under greenhouse warming
Extreme La Niña events occur when cold sea surface temperatures across the central Pacific Ocean create a strong temperature gradient to the Maritime continent in the west. This work projects an increase in frequency of La Niña events due to faster land warming relative to the ocean, and a greater chance of them occurring following extreme El Niño events.

Delays in reducing waterborne and water-related infectious diseases in China under climate change
Millions of people in China lack ready access to clean water and sanitation. Projected impacts of climate change may delay China’s progress towards reducing the burden of water-, sanitation- and hygiene-attributable infectious disease.

Threat to future global food security from climate change and ozone air pollution
This study shows that climate change has the potential to substantially increase undernourishment rates and threaten food security in developing countries through crop damage, but that ozone regulation can significantly offset climate impacts, depending on the scenario. The findings should help policymakers devise optimal strategies for food production under global climate change.

Occurrence and persistence of future atmospheric stagnation events
Atmospheric stagnation can have serious health implications due to increased pollution exposure. This study investigates how global warming will alter atmospheric circulation and the resulting changes in the frequency and persistence of stagnation events. The authors find an overall increase in the size of the population exposed to these events and highlight the need to evaluate air pollution management.

Winter weather and health
There has been much debate about whether winter warming due to climate change will substantially decrease mortality in that season. Research now finds that cold severity no longer predicts the number of excess winter deaths in England and Wales.
