WMO: 2017 expected to be third hottest year on record

The World Meteorological Organization (WMO) released its provisional Statement on the State of the Climate this week, estimating that 2017 is likely to be one of the warmest years for global average surface temperature, with many high-impact events including catastrophic hurricanes, floods, heatwaves and droughts.  The Statement was released on the opening day of the United Nations climate change conference in Bonn.

WMO ‘Summer in the City’ video series

WMO and Climate Central have launched a series of “Summer in the City” videos to explain the impact of climate change on temperatures in some of the world’s major cities. The short videos have been released in a year that is already experiencing multiple heatwaves across the globe and daily temperature records, and if greenhouse gas emissions continue to increase, Earth’s average global surface temperature could rise more than 4°C by the end of the 21st century.

New cloud type spotted over Snowdonia

These dramatic clouds are the newest cloud type in over 50 years and were spotted over Snowdonia, UK this weekend. 

Asperitas formations are incredibly rare and look like rough, sea waves in the sky. The base of these clouds is usually between 4,000 - 10,000ft (1 – 3km) and as with all cloud names, they are derived from Latin with aspero meaning ‘roughness’.  At first glance, or when doing research, they may appear to fall into the undulatus clouds category, however they are more chaotic and have less horizontal structure compared to undulatus clouds.
