In pitch dark at 40 below, a research expedition set out to the icy Arctic Ocean in January 2015.Their goal: to better understand ongoing changes in the Arctic due to a shift from an older and thicker ice cover that would survive the summer melt to a younger and thinner one that, to a larger degree, melts away in the summer.

As atmospheric CO 2 continues to increase, more and more CO 2 enters the ocean, which reduces pH (pH is a measure of acidity, the lower the pH, the more acidic the liquid) in a process referred to as ocean acidification. Declines in surface ocean pH due to ocean acidification are already detectable and accelerating.
All life depends on a healthy planet, but the interwoven systems of atmosphere, oceans, watercourses, land, ice cover and biosphere, which form the natural environment, are threatened by human activities. The Global Atmosphere Watch (GAW) programme provides reliable scientific data and information on aerosols, greenhouse gases, selected reactive gases, ozone, ultraviolet radiation and precipitation chemistry (or atmospheric deposition).

Weather is a key factor determining the success of the Winter Games. The next Winter Olympic Games will take place from 4 to 20 February 2022, in the municipality of Beijing and the neighbouring Hebei province, in China. The Paralympic Games will follow a month later, from 4 to 13 March. The scheduling of the outdoor events for the Games will rely on very short-term forecasting and nowcasting.

A concerted campaign to boost weather, ice and atmospheric observations in some of the most remote and inhospitable parts on Earth started this week, with the launch of a three-month Special Observing Period in the Antarctic. With days getting longer, the summer is about to start on the Antarctic continent. November is the month when the austral field season begins. This summer, extra atmospheric and sea-ice measurements in addition to the routine observations will be carried out as a contribution to the Year of Polar Prediction (YOPP).
