Diabetes and climate change: current evidence and implications for people with diabetes, clinicians and policy stakeholders

Author: Ratter-Rieck, Jacqueline M.; Roden, Michael; Herder, Christian Description: Climate change will be a major challenge for the world’s health systems in the coming decades. Elevated temperatures and increasing frequencies of heat waves, wildfires, heavy precipitation and other weather extremes can affect health in many ways, especially if chronic diseases are already present. Impaired responses to heat stress, including compromised vasodilation and sweating, diabetes-related comorbidities, insulin resistance and chronic low-grade inflammation make people with diabetes particularly vulnerable to environmental risk factors, such as extreme weather events and air pollution. Additionally,…

Nuclear energy – The solution to climate change?

Author: Muellner, Nikolaus; Arnold, Nikolaus; Gufler, Klaus; Kromp, Wolfgang; Renneberg, Wolfgang; Liebert, Wolfgang Description: With increased awareness of climate change in recent years nuclear energy has received renewed attention. Positions that attribute nuclear energy an important role in climate change mitigation emerge. We estimate an upper bound of the CO2 saving potential of various nuclear energy growth scenarios, starting from our projection of nuclear generating capacity based on current national energy plans to scenarios that introduce nuclear energy as substantial instrument for climate protection. We then look at needed uranium…

Soil microbiomes and climate change

Author: Jansson, Janet K.; Hofmockel, Kirsten S. Description: The soil microbiome governs biogeochemical cycling of macronutrients, micronutrients and other elements vital for the growth of plants and animal life. Understanding and predicting the impact of climate change on soil microbiomes and the ecosystem services they provide present a grand challenge and major opportunity as we direct our research efforts towards one of the most pressing problems facing our planet. In this Review, we explore the current state of knowledge about the impacts of climate change on soil microorganisms in different…

Climate change has likely already affected global food production

Author: Ray, Deepak K.; West, Paul C.; Clark, Michael; Gerber, James S.; Prishchepov, Alexander V.; Chatterjee, Snigdhansu Description: Crop yields are projected to decrease under future climate conditions, and recent research suggests that yields have already been impacted. However, current impacts on a diversity of crops subnationally and implications for food security remains unclear. Here, we constructed linear regression relationships using weather and reported crop data to assess the potential impact of observed climate change on the yields of the top ten global crops-barley, cassava, maize, oil palm, rapeseed, rice,…

Climate change and the South Asian summer monsoon

Author: Turner, A.G.; Annamalai, H. Description: The vagaries of South Asian summer monsoon rainfall on short and long timescales impact the lives of more than one billion people. Understanding how the monsoon will change in the face of global warming is a challenge for climate science, not least because our state-of-the-art general circulation models still have difficulty simulating the regional distribution of monsoon rainfall. However, we are beginning to understand more about processes driving the monsoon, its seasonal cycle and modes of variability. This gives us the hope that we…

Fire history and climate change in giant sequoia groves

Author: Swetnam, T.W. Description: Fire scars in giant sequoia [Sequoiadendron giganteum (Lindley) Buchholz] were used to reconstruct the spatial and temporal pattern of surface fires that burned episodically through five groves during the past 2000 years. Comparisons with independent dendroclimatic reconstructions indicate that regionally synchronous fire occurrence was inversely related to yearly fluctuations in precipitation and directly related to decadal-to-centennial variations in temperature. Frequent small fires occurred during a warm period from about A.D. 1000 to 1300, and less frequent but more widespread fires occurred during cooler periods from about…

Using archived television video footage to quantify phenology responses to climate change

Author: De Frenne, Pieter; Van Langenhove, Lisa; Van Driessche, Alain; Bertrand, Cedric; Verheyen, Kris; Vangansbeke, Pieter Description: Predicting how the timing of cyclic life-history events, such as leafing and flowering, respond to climate change is of paramount importance due to the cascading impacts of vegetation phenology on species and ecosystem fitness. However, progress of this field is hampered by the relative scarcity, and geographic and phylogenetic bias, of long-term phenology datasets. By taking advantage of archived television video footage, we here developed an innovative tool using previously unexploited records to…

Climate change and wind intensification in coastal upwelling ecosystems

Author: Sydeman, W.J.; Garcia-Reyes, M.; Schoeman, D.S.; Rykaczewski, R.R.; Thompson, S.A.; Black, B.A.; Bograd, S.J. Description: In 1990, Andrew Bakun proposed that increasing greenhouse gas concentrations would force intensification of upwelling-favorable winds in eastern boundary current systems that contribute substantial services to society. Because there is considerable disagreement about whether contemporary wind trends support Bakun’s hypothesis, we performed a meta-analysis of the literature on upwelling-favorable wind intensification. The preponderance of published analyses suggests that winds have intensified in the California, Benguela, and Humboldt upwelling systems and weakened in the Iberian…

Climate change increases risk of extreme rainfall following wildfire in the western United States

Author: Touma, Danielle; Stevenson, Samantha; Swain, Daniel L.; Singh, Deepti; Kalashnikov, Dmitri A.; Huang, Xingying Description: Post-wildfire extreme rainfall events can have destructive impacts in the western United States. Using two climate model large ensembles, we assess the future risk of extreme fire weather events being followed by extreme rainfall in this region. By mid-21st century, in a high warming scenario (RCP8.5), we report large increases in the number of extreme fire weather events followed within 1 year by at least one extreme rainfall event. By 2100, the frequency of…

Consequences of future climate change and changing climate variability on maize yields in the midwestern United States

Author: Southworth, J.; Randolph, J.C.; Habeck, M.; Doering, O.C.; Pfeifer, R.A.; Rao, D.G.; Johnston, J.J. Description: Any change in climate will have implications for climate-sensitive systems such as agriculture, forestry, and some other natural resources. With respect to agriculture, changes in solar radiation, temperature, and precipitation will produce changes in crop yields, crop mix, cropping systems, scheduling of field operations, grain moisture content at harvest, and hence, on the economics of agriculture including changes in farm profitability. Such issues are addressed for 10 representative agricultural areas across the midwestern Great…
