Copernicus and Climate – Cité de l’Espace

In a bulletin posted online in mid-May 2022, Matteo France “Initial heat“With”30-34 C in most areas“Thus, the agency warns that in the first 15 days of May, the average temperature observed in France was 2.7 degrees Celsius higher than normal established from 1981 to 2010. If this particular heat wave cannot be attributed solely to climate change, Meteo France explains that”In the face of climate change, the duration of heat waves is becoming more frequent And the tendency to settle earlier in the spring than ever before

Copernicus observed the climate

A very clear warning that, however, is consistent with the forecasts established by the various reports of the IPCC (or IPCC in English). Intergovernmental Panel on Climate Change Made in 1988. Heat waves are events that directly affect daily life, sometimes dramatically, as has recently happened in India and Pakistan with temperatures of 50 degrees Celsius.
Thanks in particular to the Sentinel family of satellites, the European Earth observation program Copernicus monitors the condition of our planet, as shown by sea level, vegetation cover, amount of ice and, of course, temperature. On the map below.

This type of map is based on data collected on the ground and via satellite. Even if we see lower temperatures here than normal (the reference period for this map is 1991-2020), analysis of the measurements collected over the decades points to an undeniable general increase (graphs below).

We know thatApril 2022 is the sixth warmest month of April Only 0.2 ° C was recorded during April 2016 and 2020 compared to the previous record. This search applies to the entire planet worldwide For Europe, on the other hand, April 2022 is thus 0.42 C lower than the 1991-2020 reference. The Climate change is indeed a global phenomenon And some regional holidays do not signal that the situation will improve without a concerted effort to reduce greenhouse gases.

C3S: Concrete equipment for climate

More frequent heat waves, as Meteo France warns above, are not the only consequence of climate change. Tensions over harvesting threaten food security (see our previous article), threaten the growing coastal region of the sea, impact on ecosystems, and so on. There are many negative consequences And the identified risks go as far as geopolitical instability. As a European-funded Earth Observation Program, Copernicus Not intended to make the necessary political decisions (e.g. legislation to reduce greenhouse gas emissions). On the other hand, it is defined as a tool for providing verified information about the state of the earth: “The main users of Copernicus services are policy makers and government authorities who need this information to develop laws and policies.(Quoted from Copernicus website).
For example, Copernicus includes a service that is entirely dedicated and entitled to the climate. C3S for Copernicus climate change services. In the policy of free availability of always collected data, C3S distributes regular bulletins. More targeted to the general public, such as Climate Now, March 2022 version which you can see below.

C3S produces more technical publications, from which, for example, temperature maps and graphs that you read earlier in this article. All of this work is called the Climate Bulletin and can be found online at the Copernicus website.

Each year, C3S establishes a Climate European state Which gives an overview of the evolution of climate conditions and their multiple effects. The 2021 report recalls that from 1850-1900, The planet’s global temperature has risen by 1.2 degrees Celsius And 2.2 C for Europe. The entire European climate state, including statistics, maps and diagrams, is freely accessible online.
This essential role of Copernicus will be discussed Copernicus Day from May 20 to 24 Upcoming and recent broadcasts will be on May 21 and 22 in Toulouse’s City de l’Space.
