Global temeprature anomaly highest since 2009-10, says Report

global temperature comparison

The Copernicus Climate Change Service (C3S) published Friday a comparison between global average temperatures over the last few months and the last 30 years.

Twelve-month averages of global temperatures relative to 1981–2010 reached a value in June 2015 that is comparable with peak values experienced in 2005 and 2009-10, according to figures released by ECMWF. The 12-month period up to June 2015 was about 0.3°C warmer than the average global temperature over the period 1981 to 2010.

A temperature anomaly map for July 2014 to June 2015 shows warm anomalies in most parts of the globe, with the exception of much of Antarctica, western North America and Greenland and parts of the Atlantic.

Looking just at June 2015, there is a broadly similar pattern of temperature anomalies relative to 1981 to 2010, but there are some regional variations. For example, temperatures in northern Europe are below average, most likely associated with cool North Atlantic Ocean temperatures.

These findings are based on the ECMWF ERA-Interim reanalysis dataset for near-surface air temperatures. ECMWF reanalysis combines information from past meteorological observations with modern forecast models, using data assimilation techniques originally developed for numerical weather prediction.

C3S is currently in a two-year proof-of-concept phase. It is part of the EU’s flagship Copernicus Earth observation programme. The service will give access to authoritative, quality-assured information about the past, current and future states of the climate in Europe and worldwide. It will build on national and international expertise to help EU member states improve their adaptation and mitigation policies.

It can help the private sector too, by providing businesses with the information they need to seize the opportunities offered by the transition to an energy-efficient society. And it will benefit the world as all the products and services it provides will be openly available, free of charge.

Both Copernicus Services implemented by ECMWF, (Climate Change and Atmosphere Monitoring) are present at ‘Our Common Future under Climate Change’ conference taking place in Paris this week.

Copernicus is the European Union’s revolutionary Earth Observation and Monitoring programme, looking at our planet and its environment for the ultimate benefit of all European citizens. In addition to the Copernicus Climate Change and Atmosphere Monitoring Services, Copernicus addresses four more thematic areas: land and marine monitoring, emergency management, and security.
