The production of renewable energy is increasing every year. But after analysing the growth rates of wind and solar power in 60 countries, researchers at Chalmers University of Technology and Lund University in Sweden and Central European University in Vienna, Austria, conclude that virtually no country is moving sufficiently fast to avoid global warming of 1.5°C or even 2°C. The article “National growth dynamics of wind and solar power compared to the growth required for global climate targets” was published in the journal Nature Energy, written by Aleh Cherp, Vadim Vinichenko, Jale Tosun, Joel A.Gordon and Jessica Jewell.

Researchers in the UK and Africa have teamed up to help tea producers better understand future climate risks in a bid to reduce crop damage. Kenya and Malawi produce more than half the tea Britons consume, and the crop makes up about 7% of Malawi’s GDP and 4% of Kenya’s.

Non-communicable diseases (NCDs) are fatal for more than 38 million people each year and are thus the main contributors to the global burden of disease accounting for 70% of mortality. The majority of these deaths are caused by cardiovascular disease (CVD). The risk of NCDs is strongly associated with exposure to environmental stressors such as pollutants in the air, noise exposure, artiﬁcial light at night, and climate change, including heat extremes, desert storms, and wildﬁres. In addition to the traditional risk factors for CVD such as diabetes, arterial hypertension, smoking, hypercholesterolaemia, and genetic predisposition, there is a growing body of evidence showing that physicochemical factors in the environment contribute signiﬁcantly to the high NCD numbers. Furthermore, urbanization is associated with accumulation and intensiﬁcation of these stressors. This comprehen-sive expert review will summarize the epidemiology and pathophysiology of environmental stressors with a focus on cardiovascular NCDs. We will also discuss solutions and mitigation measures to lower the impact of environ-mental risk factors with focus on CVD.

An Israeli nation-wide study of more than 600,000 births, led by a researcher at Bar-Ilan University's Azrieli Faculty of Medicine, reveals consistent links between high and low temperatures and low fetal birth weight, particularly exposure to heat during the second and third trimesters. Published in the journal Environmental Health Perspectives, the study evaluates critical windows of susceptibility to extreme low and high temperatures during pregnancy and fetal growth in a nationwide cohort of 624,940 singleton term births in Israel during the period 2010-2014.

Why is swift action to protect the climate so important and what is the scientific basis for calculations on causes and consequences of climate change? The Leopoldina explains this in its "Factsheet Climate change: causes, consequences and possible actions". In the first two chapters of this publication, the currently available knowledge about the causes and consequences of climate change has been summarized in an easy-to-understand format. The connections and data are illustrated in graphics, with concise explanations.
Employers could undo the progress made over the last 18 months and deepen workplace inequalities if organisations fail to override the deep-rooted perceptions of ‘office culture’, a leading think tank has warned. New research, led by the Work Foundation and the Chartered Management Institute, finds that ‘traditional’ views of the workplace still stand which could exacerbate already existing inequalities in the workplace.
Formula milk trials have a high risk of bias, authors almost always report favourable conclusions, transparency is lacking, and findings are selectively reported, finds a review of evidence from recently published trials in The BMJ today.

The massive columns of smoke generated by a nuclear war would alter the world’s climate for years and devastate the ozone layer, endangering both human health and food supplies, new research shows. The international study draws on newly developed computer climate modeling techniques to paint an even grimmer picture of a global nuclear war’s aftermath than previous analyses.

A new life-cycle analysis of potentially low-greenhouse-gas options for producing hydrogen in Europe finds that only hydrogen produced using renewable electricity can be effectively zero-emission, and that hydrogen pathways involving fossil fuels, even with carbon capture and storage, have greenhouse-gas (GHG) intensity high enough to make it unlikely they can contribute to meeting the European Union's climate targets. The analysis appears as the European Union is revising its Renewable Energy Directive (REDII), which governs development of renewable energy across all sectors of the economy in Europe. The revision is part of the EU's "Fit for 55" package of measures to deliver on the European Green Deal, the EU's wide-ranging proposal to drive net GHG emissions down 55% by 2030 and reach carbon neutrality by 2050.
