The urban 'wind island effect' Cities have complex microclimates that can vary from street to street. In order to maintain quality of life in cities, it is important that the dynamics behind these microclimates is understood, so that they can be accounted for urban planning and design. A great deal is already known about the urban heat island effect, but new research is now being done on the urban wind island effect.
Greenhouse emissions from Siberian rivers peak as permafrost thaws Permafrost soils store large quantities of frozen carbon and play an important role in regulating Earth’s climate. In a study published in Nature Geoscience, researchers show that river greenhouse gas emissions rise high in areas where Siberian permafrost is actively thawing.

Deadline for climate action – Act strongly before 2035 to keep warming below 2°C If governments don't act decisively by 2035 to fight climate change, humanity could cross a point of no return after which limiting global warming below 2°C in 2100 will be unlikely, according to a new study. The research also shows the deadline to limit warming to 1.5°C has already passed, unless radical climate action is taken.

Drought increases CO2 concentration in the air Researchers have shown that during drier years the concentration of carbon dioxide in the atmosphere rises faster because stressed ecosystems absorb less carbon. This global effect is so strong that it must be integrated in the next generation of climate models.

Reaction of plants to drought can be seen in the composition of the atmosphere Hot and dry periods, such as this summer in Europe, appear to change the composition of the atmosphere. Researchers discovered a 'signal' in the composition of CO2 in the atmosphere that is caused by the reaction of the vegetation to drought. Various climate models can now be adapted in accordance with the measurements. The researchers reported their findings in Nature Geosciences on 27 August.
