Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:

How much each change to the atmosphere has warmed the world:

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
The title could have meant, "Ads Urging Canadians to Oppose Climate Laws [That Were] Paid for by Gas Industry".
Given big industry buys laws all the time, I had to spend some time figuring it out and my first impression was the wrong one. I don't think that's great for a headline. We don't have to save column inches anymore, we can have more descriptive headlines.
From the article a clearer headline would read, "Ads Urging Canadians to Oppose Climate Laws [Were] Paid for by Gas Industry". Or they could say, "Ads Paid for by Gas Industry Urge Canadians to Oppose Climate Laws". That puts the industry's lobbying right up front.
I think the issue is that who paid for the ads wasn't previously clear - the gas industry used a front group.
If you see a lot of ads promoting any political point of view, you can usually assume that someone with entirely too much money is in favor of it, and you probably shouldn't be.
