Thin on the right so far
None of the 27 outlets with a published leaning rating that ran this story are rated right.
This story is still being watched, so it is a count and not yet a finding. Coverage keeps arriving for hours after an event, and a side that has published nothing this morning may publish by tonight. If it is still true when we stop checking, we will say so plainly.
The impacts of climate change in Canada are now largely irreversible, a new federal government report states. Average temperatures across the country are expected to rise by at least 3.5 degrees Celsius by the end of the century. Even if global net-zero emissions are achieved by 2075, Canada faces significant consequences, including a nearly 50 per cent increase in the area affected by wildfires and a projected loss of more than 75 per cent of glacier mass in Western Canada. With current global climate policies, average temperatures are expected to rise by five degrees Celsius by 2100.
The report, authored by nearly two dozen government and climate science experts, also warns of more frequent and severe droughts and flash floods. It notes that wildfire smoke incurred costs between $410 million and $1.8 billion annually between 2013 and 2018. Cases of Lyme disease in Canada increased from 144 in 2009 to 2,525 in 2022.
Disagreement on government action
Ryan Ness, adaptation research director at the Canadian Climate Institute, noted a contrast between the report's findings and the level of action taken by Canadian governments. He stated that adaptation efforts are not progressing quickly enough. In contrast, the office of Environment Minister Julie Dabrusin stated the government is committed to net-zero by 2050 and has committed over $2.1 billion to implement the National Adaptation Strategy.
What the coverage left out
None of the left- or centre-rated reports printed below mention the specific details of Prime Minister Mark Carney's alleged policy changes, such as eliminating the consumer carbon price or weakening the industrial carbon pricing system, as reported by CTV News.
Still developing. We have re-checked which outlets are covering this 3 times, most recently on 4 Sept 2026, 20:30, and will add the sides that appear.
How each side covered it
Our own reading of the reporting listed below, written from the outlets’ articles rather than quoted from them. The reasoning is set out on our methodology page.
Left
15 rated outlets
- Left-rated reports led on the irreversibility of climate change impacts in Canada and the projected temperature rise. They highlighted the stark consequences, such as glacier melt and increased wildfire risk, even with emissions reductions. Several reports included commentary from Environmental Defence Canada, with associate director Julia Levin calling the report a "stark warning" and a "call to action" that depends on current policy choices. Some left-rated reports also mentioned the increased costs of wildfire smoke and the rise in Lyme disease cases.
Centre
12 rated outlets
- Centre-rated reports focused on the core findings of the federal report, stating that climate change impacts in Canada are largely irreversible and projecting significant temperature increases by the end of the century. They also noted the projected loss of glacier mass and the increase in wildfire area. Some centre-rated reports included the government's response, mentioning the commitment of over $2.1 billion to the National Adaptation Strategy.

Questions about this coverage
- How did the left and right cover Canada's climate impacts largely irreversible, new report states?
- Of the 27 outlets on this story carrying a published leaning rating, 56% are rated left, 44% are rated centre, 0% are rated right. Those percentages are shares of the rated outlets, not of every outlet that ran it, which was 30. The sections above set out what each side emphasised, in its own terms.
- Is Canada's climate impacts largely irreversible, new report states left or right?
- Neither side dominates it. Of the 27 rated outlets on this story, 56% are rated left, 44% are rated centre, 0% are rated right, and no side holds the 70% this site would want before calling a field one-sided. A story is not left or right in any case; the outlets that carried it are what carry ratings.
- Is the coverage of Canada's climate impacts largely irreversible, new report states biased?
- Canada's climate impacts largely irreversible, new report states is one event reported by 30 outlets, and this page does not rate the story as biased or unbiased. What it publishes is the spread: which outlets ran it, where named rating organisations place each of them on the spectrum, and what each side chose to lead with. A leaning rating describes an outlet's record over time, not this article, and the two should not be run together.
- Which side is not reporting Canada's climate impacts largely irreversible, new report states?
- When we first saw this story, outlets rated right had barely covered it. Coverage accretes for hours after an event, so that is where to look rather than a verdict — the split above is the current count, and it is the one to read.
- Which outlets covered Canada's climate impacts largely irreversible, new report states?
- 30 that we know of, every one of them listed further up this page with a link to its own report and to what we hold on the publisher. Nothing here is a summary of somebody else's summary: the outlets are named so the original reporting can be read.
- What are the main findings of the new federal climate report?
- The report states that climate change impacts in Canada are largely irreversible. It projects average temperatures to rise by at least 3.5 C by the end of the century, with glaciers in Western Canada losing over 75 per cent of their mass and the area burned by wildfires potentially increasing by nearly 50 per cent.
- What is the projected temperature increase for Canada by 2100?
- With current global climate policies, average temperatures in Canada are expected to rise by five degrees Celsius by the year 2100. Even with net-zero emissions by 2075, a rise of at least 3.5 C is anticipated.
- What are some of the economic and health impacts mentioned in the report?
- The report highlights that wildfire smoke costs between $410 million and $1.8 billion annually between 2013 and 2018. It also notes a significant increase in Lyme disease cases, rising from 144 in 2009 to 2,525 in 2022.
