"We are at war," Greek Prime Minister Kyriakos Mitsotakis said Monday,discussingthe wildfires ravaging his country, exacerbated by Europe's hottest month in 174 years of keeping records.

"The climate crisis is already here," he told Greece's parliament.

As multiple heat waves grip large swaths of the globe, here are some reports from some of the front lines of that battle, including in Canada.

Wildfires forced 19,000 people to flee the popular tourist island of Rhodes in Greece. Its considered the largest evacuation ever for the country and it wasnt without issues.

The fires left blackened trees,dead animals and burnt-out cars. It alsoraisedconcerns that tourists will stay away in a country where one in five people work in tourism.

A wildfire also forced evacuations from the island of Corfu, and emergency services were dealing with multiple fires near Athens.

In Italy, fires wereburning in woods and vegetation in various partsof Calabria, and Sicily's civil protection agency said the temperature in some areas in eastern Sicily rose to 47 C on Sunday, close to the record European high of 48.8Cfrom two years ago.

In Spain, voters in the general election Sunday braved temperatures expected to average above 35 degrees C, or five-to-10 degreesabove normal, in many parts of the country. Authorities distributed fans to many votingstations.

"We have the heat, but the right to exercise our vote freely is stronger than the heat," said Rosa Maria Valladolid-Prieto, 79, in Barcelona.

In Canada: Worries about the drug crisis

With temperatures soaring in Alberta, including a forecast high of 32 C today, there are concerns thedrug crisis will make extreme heat even more dangerous for vulnerable people there.

Outreach workers have beentaking extra steps to ensure people experiencing homelessness and struggling with addictionsare protected from the heat.

At the Calgary Drop-In Centre, staff are already watching out for negative effects of the heat.

"We're really looking out for things like heat exhaustion, extreme sunburn so we will supply individuals with little packets of sunscreen and dehydration," said Kevin Webb, director of emergency shelter and housing at the Calgary Drop-In Centre.

The heat wave comes at a time when Alberta is reportingrecord opioid deaths.

"My big worry is that these numbers will only be exacerbated, not just by the substance use themselves and by the toxicity of the drug supply, but also by this added stress of heat and being exposed to the elements outdoors," said Dr. Monty Ghosh, an addictions specialist and assistant professor at the University of Calgary.

"This sort of intersection between substance use and homelessness, along with the added stress of heat, can worsen their overall situation and can lead to more deaths. So we have to be extremely careful and cautious with this population."

In the U.S.: Journalistsstunned by Arizona heat

In Arizona, wheretemperatures have topped 43C every day this month, even journalists who are accustomed to life in the desert say it's never been like this.

The weather in Phoenix is so hot that cameras stop working and burn your hand, cellphones glitch and no amount of water or Gatorade can keep you going. Phoenix firefighters are keeping IVs on ice to respond to calls from people overheating.

"What worries me about this heat wave is that it's not breaking," saidPeter Prengaman, the news agency's incoming global climate and environment news director. "This could be a harbinger of future heat waves, in both Phoenix and around the world."

Associated Press photographer Matt York was surprised to learn he was suffering from heat exhaustion, after 23 years of experience in the state.

"I often carry a towel to dry off and keep the sweat from dripping in my viewfinder," he wrote. "But then I realized there was no need to wipe down. I was dry. I stopped sweating altogether. My body had no more water to give. My legs started feeling chilled, an odd sensation. Then they cramped."

His blood pressure was clocked at 178/120.

He and his partner have decided to change the way they do things, with more cool-down time, more water and an acceptance that during some assignments they'll have to call it quits.

"We typically fight through not feeling well on assignments but not with heat. It's too risky."

In politics: Climate summit host called out

The United Arab Emirateshas said it is committed to delivering targets to cut the CO2emissions causing climate change after an independent researchgroup said the country, which will host this year's COP28climate summit, is far off track.

In an analysis published last week, research consortiumClimate Action Tracker said the U.A.E. would miss its climatetargets by a large margin if it went ahead with plans to expandoil and gas production and use and would seeits CO2 emissions risethrough to 2030.

Around the world, people are experiencing heat waves, some of which are setting new records. The high temperatures have contributed to more wildfires in places like Canada and Greece, and, according to officials at the World Health Organization and World Meteorological Organization, there are potential major health impacts to the young, the elderly and the homeless.

In Sweden,climate activist Greta Thunbergwas fined about $315for disobeying police during an environmental protest at an oil facility last month. The 20-year-old Thunberg admitted to the facts but denied guilt, saying the fight against the fossil fuel industry was a form of self-defence due to the existential and global threat of the climate crisis.

A few hours after the sentencing, she and other activists returned to the oil terminal to stage another roadblock. She was again removed by police.
