Climate change will increase deaths from high temperatures in Catalonia

heat wave Catalonia

As I have mentioned in previous articles climate change and its effects threaten Catalonia. Among them we find the rise in sea level and the regression of the beaches. These are the ones that will most affect Catalonia in the coming years.

has been issued a report on climate change in Catalonia and has been presented in Barcelona. The document consists of about 624 pages and has been prepared by 141 experts from universities and research centers. How will climate change affect Catalonia?

Third Report on Climate Change in Catalonia

The report warns of an abnormally high rise in temperatures and that it can increase deaths from annual heat waves. One of the effects of climate change is the increase in the frequency of heat and cold waves and in their intensity. This is why heat wave deaths could increase as heat waves do.

So far, the annual deaths from heat waves in Catalonia are around 300. However, according to this published report, they could reach at 2.500 by 2050. The part of the population most affected by heat waves would be the elderly and people with previous chronic diseases.

According to the report, the average temperature of Catalonia has increased by 1,55 degrees from the 50s. As the effects of climate change increase due to the increase in greenhouse gases in the atmosphere, the heat and temperature increase scenarios will worsen. It is estimated that by 2050 the average temperature will rise 1,4 degrees more.

In addition, we are talking about deaths from heat waves, but to this we must add that the increase in pollution will be aggravated by high temperatures and that it is currently estimated that it causes 3.500 premature deaths due to damages each year.

For now, all the signs of climate change that are taking place point to an increase in extreme temperatures, these being heat waves, tropical nights, etc. Coming to have nights in which it does not go below 25 degrees.

The consequences of climate change in Catalonia

The first consequence is drought. By 2051, according to the report, the average reduction in water resources it will be around 10% in the Pyrenean basins and a maximum of 22% in the littoral basins.

Obviously, the drought results in less rain. Until now, climate change has not yet affected the rainfall regime significantly, however, in 2050 there are estimated reductions in rainfall -10% in spring, summer and fall.

Derived from the increase in temperature and the averages, there will be less precipitation in the form of snow. Snowfall will be increasingly rare. The report recommends increasing artificial snow manufacturing capacity so that ski resorts can alleviate the shortage.

As in almost all cities with a coastline, rising sea levels are a serious problem. The Catalan sea is rising by about four centimeters per decade. These changes, the report collects, it is accompanied by an increase in autumn storms and the massive mortality of species such as coral or posidonia.

Answers to this

You can no longer promote a denialism to what is happening and what is to come. There are people who deny the existence of climate change and they blame governments and scientists for acting in fear. However, the evidence is there: the general increase in temperatures, the displacement and changes in the length of the seasons will also have consequences in asthma attacks and allergies (currently between 20% and 25% of the population suffer some type of allergy).

high temperatures

Also of the potential risk of suffering tropical diseases such as dengue, malaria or chikungunya, which would be added to other diseases transmitted by the deterioration of the water, aggravated by the drought. By 2100, according to the report itself, Catalonia may decrease to by 13% its water resources.
