Good afternoon, and welcome to Globe Climate, a newsletter about climate change, environment and resources in Canada.

Award-winning photographers Shane Gross and Cristina Mittermeier are using their images to aid global marine and freshwater ecosystem conservation efforts, and to bring public attention to the importance of our oceans.

Gross and Mittermeier joined journalists Jenn Thornhill Verma and Ryan MacDonald in a pair of conversations at a Globe and Mail event in Toronto in partnership with Rolex. Catch on up their discussion about the power of photography to spur change, responses to some of the best-known images, and current areas of focus.

Now, let’s catch you up on other news.

For this week’s deeper dive, Nova Scotians watch their backs – and each other’s. Health science reporter Jennifer Yang writes that as temperatures warm, tick populations, and their diseases, do as well.

With each year that passes, Canadian seasons are getting warmer, for longer, and ticks are expanding their range. And as tick populations have taken off, so, too, have the diseases they can spread through their bites.

Nova Scotia’s South Shore has become home to some of the country’s densest populations of blacklegged ticks – a vector for the bacterium that causes Lyme disease.

“People who haven’t even seen ticks before are seeing them, and seeing many,” says Donna Lugar, founder of the Nova Scotia Lyme Disease Support Group, which she formed in 2013. “I’ve never heard such horror stories as I’ve heard this year.”

And climate change is making this a reality for more and more people.

“Canada’s heating probably faster than anywhere else in the world, and the ticks are moving into those places as they warm,” says Nick Ogden, director of the modelling hub division with the Public Health Agency of Canada, who has studied ticks and Lyme disease since the 1990s.

“The range expansion of the tick has happened faster than the modelling we did a decade ago. Because it’s actually warming faster than the climate models were telling us back then.”

Communities like Lunenburg County in Nova Scotia offer a glimpse of what lies ahead for many other swaths of the country, where temperatures are rising and the ticks are inching in.

Meanwhile, nationally reported cases of Lyme disease have climbed from 522 in 2014 to a preliminary count of 5,239 last year.

Until a vaccine is a possibility, Canadians are finding other ways to fight back. Pesticides are being developed and could help, if it too can adapt to warming temperatures.
