As mangrove trees lose ground to deforestation and urban sprawl, one development seems to be giving them a boost: climate change. Fewer winter cold snaps […]

The title com­pound, tetra­ethyl­ammonium tetra­thio­rhenate, [(C2H5)4N][ReS4], has, at room temperature, a disordered structure in the space group P63mc (Z = 2, α-phase). A phase transition to the monoclinic space group P21 (Z = 2, γ-phase) at 285 K leads to a pseudo-merohedral twin. The high deviation from the hexa­gonal metric causes split reflections. However, the different orientations could not be separated, but were integrated using a large integration box. Rapid cooling to 110–170 K produces a metastable β-phase (P63, Z = 18) in addition to the γ-phase. All crystals of the β-phase are contaminated with the γ-phase. Additionally, the crystals of the β-phase are merohedrally twinned. In contrast to the α-phase, the β- and γ-phases do not show disorder.

There is sufficient evidence from tree rings, boreholes, retreating glaciers, and other proxies of past surface temperatures to say with a high level of confidence that the last few decades of the 20th century were warmer than any comparable period in the last 400 years, according to a new report from the National Research Council.

A new rapid expert consultation from a standing committee of the National Academies of Sciences, Engineering, and Medicine responds to questions from the White House Office of Science and Technology Policy (OSTP) regarding survival of the COVID-19 virus in relation to temperature and humidity and potential for seasonal reduction and resurgence of cases.

A new study highlights the positive effects of plants and trees in cities. Urban green areas provide shade and reduce temperature fluctuations, bringing average temperatures down, while covering roofs with plants, rather than black roofs, reduces the energy required to heat and cool buildings.

Sea surface temperatures in the North Atlantic may be significantly influenced by air pollution, with knock-on effects for climatic events, such as drought and hurricanes, according to a new study. The findings indicate that estimates of man-made aerosol emissions over coming decades should be refined within climate models to improve predictions of future climate change.

New research has predicted that, if current warming continues, an important type of coral in the central Red Sea could stop growing by 2070. Although the same coral has recovered after previous short-term warming events, it appears that the current continuing trend in warming is likely to be more damaging.

Higher temperatures being brought about by global warming are increasing methane emissions from the extensive northern European peatlands, a recent study has found. The researchers also say that future estimations of greenhouse gas emissions can be improved via better land-cover classification — i.e. determining how much peatland is fenland or bogland.

A thin layer of lighter coloured asphalt applied to road surfaces could significantly lower surface temperatures in hot urban areas, according to a recent study. This could make living conditions more comfortable and reduce the amount of energy needed to cool buildings.

As the climate changes, animal species are predicted to adapt by moving northwards so they can remain within their preferred temperature range. Now, researchers have found that bird and butterfly populations are not keeping up with changing temperatures and, on average, European bird and butterfly species lag around 212km and 135km, respectively, behind climate changes.

Increasing temperatures and rising ocean acidification could reduce the health and survival of young sharks, new research has shown. Bamboo shark embryos incubated under ocean temperatures and acidity predicted for 2100 showed survival rates of 80% compared to 100% survival under present-day conditions. Once hatched, survival measured at 30 days was only 44% for those under predicted climate change conditions, again compared to 100% for those experiencing current temperature and acidity.

• The White House reportedly plans to go ahead with a plan to institute temperature screenings at 20 US airports in order to instill confidence that air travel is safe, according to USA Today.
• According to leaked emails, a top CDC official said that such a strategy was ineffective and asked that the agency be excluded from the plan.
• Temperature checks do not account for asymptomatic COVID-19 cases, pre-symptomatic cases, or people with COVID-19 who do not have a fever.
• The report comes one day after an Associated Press report found that the White House had buried CDC guidance for re-opening businesses, schools, and churches.
• Visit Business Insider's homepage for more stories.

The Trump administration reportedly ignored guidance from the Centers for Disease Control and Prevention over temperature screenings at airports and plans to go ahead with them, even though they were ineffective in initially preventing the spread of COVID-19 in the US.

The move, which would require temperature screenings at 20 US airports, was detailed in leaked documents reported by USA Today on Saturday. In an email to officials at the Department of Homeland Security, Dr. Martin Cetron, the director of global mitigation and quarantine at the CDC had argued "thermal scanning as proposed is a poorly designed control and detention strategy as we have learned very clearly."
