A recent study found-that more than a third of all heat deaths worldwide can be attributed to climate change. Parts of the U. S. are feeling the danger now. Heat waves, like the one that has held the Northwest United States in its grip for the past week, are deadly.

The human toll (伤亡人数) of the record-breaking temperatures that struck both coasts of the U. S. and Canada in recent weeks is already enormous. At least 80 people have died in the U. S during the past few days of extreme heat；in British Columbia, the number is in the hundreds. And, as more data trickles in, those numbers are likely to rise even further.

A mountain of scientific research has shown that climate change is making heat waves longer, hotter, more likely, and more dangerous. A recent study published in Nature Climate Change adds additional detail by assessing the human cost of that extra heat:In June, a team of some 70 researchers reported that for the 732 sites on 6 continents they studied, on average, 37 percent of all heat-related deaths can be blamed directly for climate change.

The study underlines the urgency with which we need to address human-caused climate change, says Ana Vicedo Cabrera, lead author of the study and a climate change epidemiologist at the University of Bern, in Switzerland.

"Climate change is not something in the future:It's something in the present, and it is already affecting our health in very dramatic ways, "she says. Extreme, deadly heat events like the one hitting North America are a warning of what will come. "We can expect that what we've seen in the past is going to increase exponentially in the future. Our choices for the future are more of this, or a lot more of this. We can still choose between bad and worse, "he says.

Either way, it is well past time to start helping people across the country prepare for extreme heat, says University of Washington's Kristie Ebi, a global environmental health expert. Some actions can be simple, like making sure people have access to fans, air conditioning, and shade. But the basic message is simple, according to Ebi:We can choose to save lives. "Heat kills, but it doesn't have to, "she says.
