Spain sweltered under an unrelenting heat wave as temperatures started to build toward what is forecast to be a torrid weekend across southern Europe.

Spain's weather service said thermometers could potentially hit 45 C (113 F) in southeastern areas of the Iberian Peninsula, which are under alert for extreme heat. That mark was reached Monday in the village of Loja near Granada at the start of the heat wave that is causing restless nights across the country.

Warmer, drier weather because of an earlier than usual El Nino is expected to hamper rice production across Asia, hitting global food security in a world still reeling from the impacts of the war in Ukraine.

An El Nino is a natural, temporary and occasional warming of part of the Pacific that shifts global weather patterns, and climate change is making them stronger. The National Oceanic and Atmospheric Administration announced this one in June, a month or two earlier than it usually does. This gives it time to grow. Scientists say there's a one in four chance it will expand to supersized levels.

After a historically wet winter and a cloudy spring, California's summer was in full swing Thursday as a heat wave that's been scorching much of the U.S. Southwest brings triple digit temperatures and an increased risk of wildfires.

Blistering conditions will build Friday and throughout the weekend in the central and southern parts of California, where many residents should prepare for the hottest weather of the year, the National Weather Service warned.

Mohammed Hamid Nour is only 23, but he is already nostalgic for how Iraq's Mesopotamian marshes once were before drought dried them up, decimating his herd of water buffaloes.

Even at their centre in Chibayish, only a few expanses of the ancient waterways -- home to a Marsh Arab culture that goes back millennia -- survive, linked by channels that snake through the reeds.

As much of the world swelters in record temperatures, spare a thought for Issam Genedi, who ekes out a living washing cars in one of the planet's hottest regions, the Gulf.

Pausing from his work at an outdoor carpark in Dubai, the Egyptian migrant says the United Arab Emirates' furnace-like summer feels even hotter this year.

Record global ocean heating has invaded Florida with a vengeance.

Water temperatures in the mid-90s (mid-30s Celsius) are threatening delicate coral reefs, depriving swimmers of cooling dips and adding a bit more ick to the Sunshine State's already oppressive summer weather. Forecasters are warning of temperatures that with humidity will feel like 110 degrees (43 degrees Celsius) by week's end.

Protesters and legislators converged on the European Union parliament Tuesday as the bloc prepared a cliffhanger vote on protecting its threatened nature and shielding it from disruptive environmental change, in a test of the EU's global climate credentials.

Spurred on by climate activist Greta Thunberg, a few hundred demonstrators demanded that the EU pushes through a bill to beef up the restoration of nature in the 27-nation bloc that was damaged during decades of industrial expansion. A counterdemonstration of farmers demanded a slower approach that would lessen the impact on their income.

Authorities in Iceland on Tuesday warned tourists and other spectators to stay away from a newly erupting volcano that is spewing lava and noxious gases from a fissure in the country's southwest.

The eruption began Monday afternoon after thousands of earthquakes in the area, meteorological authorities said. This one comes 11 months after its last eruption officially ended. The eruption is in an uninhabited valley near the Litli-Hrútur mountain, some 30 kilometers southwest of the capital, Reykjavik.
