Leaders of nations overwhelmed by fallouts from wars and ravaged by political divisions are gathering in western Morocco, where they will attempt during the next two weeks to unite around a cooperative new approach to easing the worsening ravages of global warming.
Bare trunks of dead coastal forests are being discovered up and down the mid-Atlantic coastline, killed by the advance of rising seas. “Ghost forests” offer eerie evidence of some of the world’s fastest rates of sea level rise.
Two key climate change indicators — global surface temperatures and Arctic sea ice extent — have broken numerous records through the first half of 2016, according to NASA analyses of ground-based observations and satellite data.
2016 is set to be the hottest year on record by a significant margin, with temperatures that are 2.2˚F (1.2˚C) above pre-industrial times, the World Meteorological Organization told diplomats gathered in Marrakech, Morocco, to discuss international action to limit global warming to less than 2˚C by the end of the century.
In a warming world, soils dry out more from evaporation, making droughts worse and further drying out vegetation, raising risk of wildfires. Higher evaporation rates also provide fuel for hurricanes, allowing them to produce heavier rain. Warming oceans and glacial melt cause the sea level to rise, which translates into higher storm surge. These factors can be linked to billions of dollars of damages from disasters in 2017.
Climate Central ranks the average summer temperature and precipitation totals for their Climate Matters markets. They compare all summers in each market’s period of record, and rank them into five equal groups. Data shows it has been a summer of extremes.
On September 25, 2019, the IPCC released its Special Report on the Ocean and Cryosphere in a Changing Climate. Climate Central has complied resources and communications tools to cover this work of more than 100 scientists.
Loss of ice can have ecological effects on aquatic species by changing stream water volume, water temperature and run-off timing in the higher elevations of the park. Tracking these small alpine glaciers has been instrumental in describing climate change effects on Glacier National Park to park management and the public.
