Increased atmospheric carbon dioxide promotes algal growth
It is usually thought that unlike terrestrial plants, submerged plants like algae will not show any response to an increase of atmospheric carbon dioxide. This view may be biased by neglect of the effects of plants themselves on water chemistry. In Ecology Letters, June, Schippers, Lürling and Scheffer of the Wageningen University show that, if this effect is included, productivity may double due to a doubling of the atmospheric carbon dioxide concentration.

The Eurasian atmospheric circulation anomalies can persist from winter to the following spring
Surface air temperature (SAT) anomalies have pronounced impacts on agriculture, socioeconomic development, and people's daily lives. A question is whether the Eurasian atmospheric circulation anomalies can persist from winter to the following spring. Using observational data and atmospheric model simulation, scientists from the Institute of Atmospheric Physics of the Chinese Academy of Sciences reported that the dominant mode of winter Eurasian 500-hPa geopotential height anomalies could maintain to the following spring.

Atmospheric CO2 concentration at Syowa Station in Antarctica exceeds 400 ppm
At Syowa Station, Antarctica, the atmospheric CO2 concentration exceeded 400 ppm on May 14, 2016, for the first time since observations were initiated there in 1984. The monthly mean CO2 for June 2016 also exceeded 400 ppm. CO2 is one of the most important greenhouse gases, and global warming owing to the increase in atmospheric CO2 has become a serious problem worldwide. Therefore, it is crucial to continue monitoring atmospheric CO2. (2016-10-25)

Ocean warming could drive heavy rain bands toward the poles
In a world warmed by rising atmospheric greenhouse gas concentrations, precipitation patterns are going to change because of two factors: one, warmer air can hold more water; and two, changing atmospheric circulation patterns will shift where rain falls. According to previous model research, mid- to high-latitude precipitation is expected to increase by as much as 50 percent. Yet the reasons why models predict this are hard to tease out.
