A large majority of European Union countries want stronger EU action to prepare for the health consequences of climate change and global warming's potential to spread vector-borne diseases, a document seen by Reuters showed.

Europe is experiencing severe health impacts as a result of the changing climate. Around 61,000 people are estimated to have died in sweltering European heatwaves last summer, suggesting countries' heat preparedness efforts are falling well short.

In a joint paper, 20 of the EU's 27 member countries including Croatia, Germany, Greece, Malta and the Netherlands, have urged the EU to increase its surveillance of the threats to health and healthcare systems posed by extreme weather, to help countries prepare.

The EU should also draft plans for infections of zoonotic and climate-sensitive vector-borne diseases, and strengthen its early warning and response system for if disease-spreading vectors are detected, the countries said.

"Unless proactive measures are taken, it is a matter of time before certain preventable infectious diseases, which are currently more prevalent in other regions, become increasingly common occurrences within the EU," the paper said.

It was also backed by Austria, Belgium, Cyprus, the Czech Republic, Denmark, Estonia, Hungary, Ireland, Italy, Latvia, Lithuania, Luxembourg, Portugal, Romania and Slovenia.

Climate change is increasing the risk that infectious diseases will spread into new areas - including in Europe, as summers become hotter and longer, and increased flooding creates favorable conditions for spreading infectious disease.

An example of this is the tiger mosquito, which is now present in 337 regions in Europe - more than double the number a decade ago, said the paper, which was reported earlier on Monday by the Financial Times.

EU countries' health ministers will discuss the paper in a meeting next week. The EU is currently drafting its first climate risk assessment, due to be published next year as a basis for future policies to cope with climate hazards like heatwaves and wildfires.

Killer Whales Spotted Grooming Each Other with Seaweed

Killer whales have been caught on video breaking off pieces of seaweed to rub and groom each other, scientists announced Monday, in what they said is the first evidence of marine mammals making their own tools.

Humans are far from being the only member of the animal kingdom that has mastered using tools. Chimpanzees fashion sticks to fish for termites, crows create hooked twigs to catch grubs and elephants swat flies with branches.

Tool-use in the world's difficult-to-study oceans is rarer, however sea otters are known to smash open shellfish with rocks, while octopuses can make mobile homes out of coconut shells.

A study published in the journal Current Biology describes a new example of tool use by a critically endangered population of orcas., AFP reported.

Scientists have been monitoring the southern resident killer whales in the Salish Sea, between Canada's British Columbia and the US state of Washington, for more than 50 years.

Rachel John, a Masters student at Exeter University in the UK, told a press conference that she first noticed "something kind of weird" going on while watching drone camera footage last year.

The researchers went back over old footage and were surprised to find this behavior is quite common, documenting 30 examples over eight days.

One whale would use its teeth to break off a piece of bull kelp, which is strong but flexible like a garden hose.

It would then put the kelp between its body and the body of another whale, and they would rub it between them for several minutes.

The pair forms an "S" shape to keep the seaweed positioned between their bodies as they roll around.

Whales are already known to frolic through seaweed in a practice called "kelping".

They are thought to do this partly for fun, partly to use the seaweed to scrub their bodies to remove dead skin.

The international team of researchers called the new behavior "allokelping," which means kelping with another whale.

They found that killer whales with more dead skin were more likely to engage in the activity, cautioning that it was a small sample size.

Whales also tended to pair up with family members or others of a similar age, suggesting the activity has a social element.

The scientists said it was the first known example of a marine mammal manufacturing a tool.

Janet Mann, a biologist at Georgetown University not involved in the study, praised the research but said it "went a bit too far" in some of its claims.

Bottlenose dolphins that use marine sponges to trawl for prey could also be considered to be manufacturing tools, she told AFP.

And it could be argued that other whales known to use nets of bubbles or plumes of mud to hunt represent tool-use benefitting multiple individuals, another first claimed in the paper, Mann said.

Michael Weiss, research director at the Center for Whale Research and the study's lead author, said it appeared to be just the latest example of socially learned behavior among animals that could be considered "culture".

But the number of southern resident killer whales has dwindled to just 73, meaning we could soon lose this unique cultural tradition, he warned.

"If they disappear, we're never getting any of that back," he said.

The whales mainly eat Chinook salmon, whose numbers have plummeted due to overfishing, climate change, habitat destruction and other forms of human interference.

The orcas and salmon are not alone -- undersea kelp forests have also been devastated as ocean temperatures rise.

Unless something changes, the outlook for southern resident killer whales is "very bleak," Weiss warned.
