The Algarve’s water crisis worsens

Barlavento reservoir

Reservoir levels in the Algarve have fallen agai n, coinciding with global temperatures approaching record highs.

The amount of water stored in all the Algarve’s river basins fell in June and again in July. The Barlavento basin in the western Algarve is the worst affected, with a level now below 20%. The Arade in the central Algarve fell from 40.8% in June to 37.8% last month. 

The situation is much better in the east of the region. The Guadiana basin is 83.35% full, and the Mondego reservoir has a level of 85.5%.

Official meteorological statistics show that at the end of June the south of Portugal was suffering extreme drought, while the intensity was more moderate in the cities of Beja and Evora in the Alentejo, as well as part of the districts of Setubal, south of Lisbon.

Current temperatures in the Algarve are fairly mild compared to other Portuguese places in the past. Portugal's highest recorded temperature is just above 47.4 degrees Celsius (117.32 Fahrenheit). Normal summer temperatures in the Algarve stay in the mid-30s °C, but sometimes soar towards 40 °C (104 °F). 

On Sunday, July 21, the world experienced its hottest day on record. Just 24 hours later that record was broken,  marking the hottest recorded in thousands of years.

The European Union’s Copernicus Climate Change Service has been able to accurately reveal this as they have developed a scientific technique for assessing historical temperatures. The technique can be used in a variety of helpful ways, including suggesting the best spots to place wind farms and letting homeowners know how much their solar panels might generate. 

Severe heat waves cause hundreds, if not thousands of deaths across Europe, the United States, and Asia. The United States Embassy in Lisbon has issued a warning to American summer visitors to Portugal to be careful of the possible consequences of being outdoors in the local heat.

Europe is the fastest-warming continent in the world. It is rising roughly twice the global average, according to official data. The hottest places on the planet just now are in parts of countries including Saudi Arabia, Mexico, and Pakistan. The biggest problem of all is the failure of humans to properly control climate change.

While the Algarve is at the peak of its wildfire season, all units of fire brigades, police forces, and various volunteer groups are on constant standby to deal with any outbreaks. So far, such outbreaks have been most severe in Alberta, Canada, and parts of California. There are currently about 100 large wildfires raging in California. One of them is the worst in Californian history. 

The existential threat of global warming does not seem to be nearly as important to many world leaders nowadays as spiralling knife and gun violence, and international wars.

However, Bloomberg Green has just come up with some good news: “Last year, the world invested $1.8 trillion in climate tech. Much of that went toward renewable energy and electrifying transport, climate tech sectors that are relatively mature. Pioneers — a program that’s run for more than a decade — focuses on areas where innovation is most needed, ranging from reducing buildings’ carbon footprints and developing clean fuels.”

The United Nations Secretary-General and former Portuguese Prime Minister António Guterres recently delivered a special address on climate action in which he warned that we have only 18 months to save the world.

Pulling back from the brink “is still just about possible”, he continued, but only if we fight harder. It all depends on decisions taken by political leaders during this decade.”
