2015 Trends as the Year of Ominous Weather Records

The state of global climate will make history in 2015... – WMO

The World Meteorological Organisation (WMO) has come out with a press release on its most current findings about the state of the global climate. It usually reserves its full report until data for an entire year has been collected however as fodder for the World Climate Summit in Paris next month it issued this most current report. I excerpt the most pertinent statements below. The full press release can be read here.

Temperatures have now risen 1 degree Celsius since pre-industrial times (1880-1899).

Levels of greenhouse gasses in the atmosphere reached new highs and in the Northern Hemisphere spring 2015 the three month average global concentration of CO2 crossed 400 ppm (parts per million) barrier for the first time.

The global average sea-surface temperature, which set a record last year, is likely to be met or beaten this year. 

The global air average temperature record has been "absolutely smashed in 2015." – Prof. Matthew England UNSW

This warming blows away the record breaking 1997-1998 El Nino by a massive 0.2 degrees Celsius.

These are significant changes for the climate system, with the likelihood that these are the warmest temperatures since the last ice age, and the highest levels of carbon dioxide in more than two-and-a-half-million years. 

The latest estimates of global sea level indicate that the global average sea level in the first half of 2015 was the highest since satellite observations became available in 1993.

Yemen suffered from unprecedented back to back cyclones in early November with Chapala becoming the first tropical cyclone to make landfall followed by Megh.
