Observing Water Vapour

Those who question the importance of climate change sometimes claim that reducing carbon dioxide (CO 2 ) emissions into the atmosphere will have a very limited effect, because water vapour is the most dominant greenhouse gas. If that is the case, they wonder why bother so much about CO 2 and other greenhouse gases? Observations by the WMO Global Atmosphere Watch programme have helped to investigate this in some detail.
Climate change impacts on aviation: An interview with Herbert Puempel

Efforts to reduce fuel burn and thus carbon dioxide (CO 2 ) emissions in aviation over the past four decades have been impressive. Operational measures in line with new air traffic management systems, as well as new technological concepts, all have the potential to continue reducing these CO 2 emissions. The Commission for Aeronautical Meteorology (CAeM) supports aviation stakeholders in their efforts to operate under changing climate conditions.

At 05:16 UTC on 7 October 2014, the Japanese satellite Himawari-8 atop an H-IIA rocket took off from the Yoshinobu Launch Complex Pad 1 at the Tanegashima Space Centre in Japan. The launch was flawless and the satellite arrived a few weeks later at its final geostationary orbiting position 36 000 km above the equator at 140.5°E, just north of Papua New Guinea in the Western Pacific Ocean. It was the first of a new generation of satellites that would start operations in the 2015-2021 timeframe. These new meteorological satellites have enhanced observation capability that will bring benefits,...

High costs and relatively low usage are major concerns for operational meteorological satellite systems. In the early 1990s, Tillman Mohr, then Director General of the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), made a rough calculation that the operational cost of the constellation of meteorological satellites was in the order of US$ 2 million per day. However, a WMO survey conducted around the same time determined that many of its Members were not able to access and use satellite data and products in real time and were, thus, not able to reap the...

The Intergovernmental Panel on Climate Change (IPCC), which provides policymakers with scientific information about climate change, made a big contribution to the Paris Agreement to tackle global warming. The Agreement in turn has major implications for the work of the IPCC. This article examines these implications and what the IPCC is doing to help implement The Agreement.

The weather seems to be getting wilder and weirder. People are noticing. What are the connections to human-caused climate change? And how can we best communicate what the most recent...
