Spain registered its hottest spring on record this year, and its second driest ever, the state meteorological agency said Wednesday.

Rubén Del Campo, spokesman for the Aemet weather agency, said the latest data showed a continuation of the extremely high temperatures the country suffered in 2022, which was the hottest year ever recorded in Spain.

The spring heat was accompanied by a scarcity of rain that will exacerbate Spain's long-term drought, despite some rainfall over the last month. Spain's Ecological Transition Ministry reported Tuesday that the country's reservoirs are at 47.4% of their capacity, consolidating a downward trend.

Del Campo noted knock-on effects for the Mediterranean country's ecosystem. “Surface water temperatures recorded in 2022 were the highest since at least 1940,” he told a press conference, warning that the phenomenon endangered marine life and its ability to reproduce.

The situation inland was also made much more precarious. “These high temperatures have repercussions on both human health and ecosystems in terms of increased likelihood of forest fires,” the spokesman added.

Del Campo also issued predictions for the summer ahead, which he said would likely be “extremely hot,” though with a probability of some rainstorms. The Aemet spokesman said it was not clear that the El Niño weather phenomenon would contribute to the expected high temperatures in Spain. El Niño is a cyclical warming of the world's oceans and weather, which is forecast to return later this year.

The Spanish government announced 2.2 billion euros ($2.4 billion) worth of drought response measures last month, including funding for urban water reuse and further aid for struggling farmers.

Spain is Europe’s leading producer and exporter of fresh fruit and vegetables. The country requested emergency funds from the European Union in April given the dire prognosis for this year’s crops.



Climate Change Causing More Change in Rainfall, Fiercer Typhoons, Scientists Say

Climate change is driving changes in rainfall patterns across the world, scientists said in a paper published on Friday, which could also be intensifying typhoons and other tropical storms.

Taiwan, the Philippines and then China were lashed by the year's most powerful typhoon this week, with schools, businesses and financial markets shut as wind speeds surged up to 227 kph (141 mph). On China's eastern coast, hundreds of thousands of people were evacuated ahead of landfall on Thursday.

Stronger tropical storms are part of a wider phenomenon of weather extremes driven by higher temperatures, scientists say.

Researchers led by Zhang Wenxia at the China Academy of Sciences studied historical meteorological data and found about 75% of the world's land area had seen a rise in "precipitation variability" or wider swings between wet and dry weather.

Warming temperatures have enhanced the ability of the atmosphere to hold moisture, which is causing wider fluctuations in rainfall, the researchers said in a paper published by the Science journal.

"(Variability) has increased in most places, including Australia, which means rainier rain periods and drier dry periods," said Steven Sherwood, a scientist at the Climate Change Research Center at the University of New South Wales, who was not involved in the study.

"This is going to increase as global warming continues, enhancing the chances of droughts and/or floods."

FEWER, BUT MORE INTENSE, STORMS

Scientists believe that climate change is also reshaping the behavior of tropical storms, including typhoons, making them less frequent but more powerful.

"I believe higher water vapor in the atmosphere is the ultimate cause of all of these tendencies toward more extreme hydrologic phenomena," Sherwood told Reuters.

Typhoon Gaemi, which first made landfall in Taiwan on Wednesday, was the strongest to hit the island in eight years.

While it is difficult to attribute individual weather events to climate change, models predict that global warming makes typhoons stronger, said Sachie Kanada, a researcher at Japan's Nagoya University.

"In general, warmer sea surface temperature is a favorable condition for tropical cyclone development," she said.

In its "blue paper" on climate change published this month, China said the number of typhoons in the Northwest Pacific and South China Sea had declined significantly since the 1990s, but they were getting stronger.

Taiwan also said in its climate change report published in May that climate change was likely to reduce the overall number of typhoons in the region while making each one more intense.

The decrease in the number of typhoons is due to the uneven pattern of ocean warming, with temperatures rising faster in the western Pacific than the east, said Feng Xiangbo, a tropical cyclone research scientist at the University of Reading.

Water vapor capacity in the lower atmosphere is expected to rise by 7% for each 1 degree Celsius increase in temperatures, with tropical cyclone rainfall in the United States surging by as much as 40% for each single degree rise, he said.
