Combatting plastics emissions

The life cycle greenhouse gas emissions from plastic products are expected to increase, and could represent a substantial portion of the global carbon budget by 2050 if current trends are followed. An analysis of mitigation strategies finds that, to keep emissions below the 2015 level, an aggressive strategy of decarbonizing energy infrastructure, improving recycling, adopting bio-based plastics and reduction in demand, is required.

    The unexpected swell of action, sparked by a Swedish teenager, has put climate change back on the political radar. With time on their side, youth will experience longer term climate change impacts more than those in decision making positions, meaning they want a say in their future.

    The way in which climate change research funds are managed is shifting dramatically toward investments in large collaborative research networks. This poses significant challenges for researchers, and requires changes from the institutions and funders that support them.

    Many countries are formulating a long-term climate strategy to be submitted to the United Nations Framework Convention on Climate Change by 2020. Model-based, multi-disciplinary assessments can be a key ingredient for informing policy makers and engaging stakeholders in this process.

    Climate change exposes more people to heat waves and other extreme weather events. New research shows that experiencing a heat wave can affect concerns about energy security, but not enough to change behaviour.

    The frequency of extreme weather events is increasing due to climate change. Here, the authors exploit regional variation in the UK summer heatwave of 2018 and find that exposure to extreme temperatures influenced concern about energy security.

    The life-cycle GHG emissions from plastics are expected to increase. Here, it is shown that an aggressive strategy of decarbonizing energy infrastructure, improving recycling, adopting bio-based plastics and reducing demand is required to keep emissions below 2015 levels.

    Melting glaciers are increasing Himalayan glacial lakes and potentially the risk of outburst floods. An advanced automated algorithm identifies glacial lake outburst floods from Landsat images since the late 1980s to improve understanding of these events and trends in their frequency.

    Fifty years of monthly observation of rainforest canopy trees in the Central Amazon reveals that drought, heat, storms and extreme rain can all increase tree mortality. Pioneers, softwoods and evergreen functional groups were particularly vulnerable.

    The benefits of using natural gas as a bridge fuel are often called into question. A coal-to-gas shift in China, Germany, India and the United States is broadly consistent with climate stabilization goals in the Paris Agreement, except when metrics emphasizing very short-term outcomes are used.

    The Pacific Walker circulation is predicted to weaken, however, observations suggest a current strengthening. Satellite humidity observations show a weaker response than reanalyses; coupled with model simulations, this suggests that internal variability dominates recent strengthening.

    Spaceborne thermal observation is used to monitor discrete phenophases of forest understory plants in near-real time and the thermal relationship is used to project phenological changes under future climates.
