With much of B.C. shrouded in wildfire smoke last week, it appears that a warming planet is on the minds of Canadians.

Abacus Data has reported that 34 percent of 1,500 respondents in its latest poll said they were "extremely concerned" about climate change. Another 32 percent said they are "very concerned".

The U.S. president is the only topic that generated more responses of extreme concern.

Nearly half—48 percent—used this term to describe their feelings about Donald Trump.

The poll also indicated that the Liberals would receive the support of 37 percent of respondents if an election were to be held now.

The Conservatives trailed by four points with 33 percent. The NDP was at 18 percent.

Those numbers have remained fairly static over the past month.

"Whether Maxime Bernier’s decision to leave the Conservative Party has the potential to undermine the competitiveness of Mr. Scheer’s Tories will be interesting to watch, especially in Quebec, where the Conservative brand had been seeing an uptick in support," wrote Abacus executives David Coletto and Bruce Anderson in a summary of the results.

With regard to health care, 33 percent of respondents were "extremely concerned" and 37 percent were "very concerned".

Only 29 percent said they were "extremely concerned" about housing affordability, whereas 35 percent were "very concerned" about this topic.

However, in big cities, it rose to 31 percent who were "extremely concerned" about the cost of housing. And in B.C., housing affordability was a major issue for nearly half of all residents, whereas that fell to nine percent in Alberta.

When it came to extreme weather, 21 percent were "extremely concerned" and 33 percent were "very concerned".

Another 25 percent were extremely concerned about border crossings, 23 percent were extremely concerned about government debt and deficits, 21 percent were extremely concerned about gun violence, and only 18 percent reported being extremely concerned about the legalization of cannabis.

Conservative voters were more concerned about border crossings than those who support the Liberals or the NDP.

Among all the topics polled, highest margin by far—49 percent—stated that they were "not concerned" about cannabis legalization. Only 10 percent were not concerned about climate change and six percent were not concerned about health care.
