#Humberto is now a Cat 5! It’s the first time in nearly a century with back to back seasons with Cat 5’s in the Atlantic. We are seeing our warmer future unfold in real-time, IMO. 1/

"it took about 65 years to exceed the 0.5-degree limit, just 28 years to reach the 1.0-degree limit, and it will be about 17 years if we exceed the 1.5-degree limit on a moving average in 2025 or 2026. This means that the period for each jump of 0.5 degrees is getting shorter and shorter."

“To be a good scientist, I have to take emotions out of work. Still, I would say looking at this data, when I allow myself to connect to it emotionally, then I am afraid. This really scares me” - Dr. Levke Caesar, co-lead of Planetary Boundaries Science Lab

I soon understood that she was preparing her burrow for something, as she removed sand she grabbed little "buckets" of sand with her first legs (later you'll see the remarkable sand baskets), discarding into the nearby desert ... looks like a load of laundry she did this again & again

"If there’s any lesson in this bleak update, it’s that delay is the most expensive climate policy of all. Each year of foot-dragging and each step backwards only multiplies the cost in climate impacts and the effort required later. The atmosphere isn’t waiting for us to get our politics in order."

The prevailing approach to addressing the climate crisis was destined to fail: CCI has declared our 2030 climate target 'out of reach' and, more ominously, concluded that progress is 'fragile & slipping,' & the underlying momentum is 'going the wrong way.' www.nationalobserver.com/2025/09/22/o...

Another airport expansion planned, another occasion to repeat: As long as there are no credible plans for climate neutrality of aviation, investing in airport expansion is betting on us all giving up on the Paris agreement.

The WSJ speaking: "America has given up its effort to challenge China in the renewable-energy industries that increasingly power the global economy."

Prochlorococcus — Earth’s smallest and most abundant photosynthetic organism — may see population reductions of up to 51% in tropical oceans by 2100 under moderate and high warming scenarios, according to a study in Nature Microbiology. go.nature.com/3V3mvGn 🌊 🧪

New study says more than 70 percent of Atlantic corals will "begin dying by 2040 even under optimistic climate warming scenarios."

LNG projects in BC, Canada are on track to receive CAD 3.93 billion in public support by the end of 2030. This money could be better spent accelerating growth of clean industries & helping communities adapt to climate change. 🆕 @IISD_Energy report: www.iisd.org/publications...

The list of native CA trees that are now at risk is long and growing fast -- most oaks, whitebark pines, giant sequoias, sugar pines, Joshua trees, limber pines, pinyon pines, Oregon ash, coast redwoods, desert mesquite, sycamores... 🌎

No matter how the BC government tries to spin it, this LNG export project is 100% owned by US companies, will be built in Korea, and represents a 30-megaton carbon bomb that threatens the health and livelihoods of local residents.

It's hard to overstate just how off the charts warm the Pacific is right now. The swath of the basin from California to Japan (a HUGE area) from 25N to 60N is ~3F (1.6C) above normal. To put it into math terms that is 6 Sigma/ standard deviations above the mean. More… 1/

In 2022, now-BC Premier David Eby stated, "We cannot continue to subsidize fossil fuels and expect clean energy to manifest somehow. We cannot continue to expand fossil-fuel infrastructure and hit our climate goals." Today.... thenarwhal.ca/ksi-lisims-l...

Can't say I'm surprised but it's so god damn disappointing to see a government filled with people who claim to care about climate change and Indigenous Rights approve yet another fossil fuel megaproject without the consent of affected First Nations with no regard for our climate commitments. #bcpoli

Maybe the land carbon sink is weaker than we thought. Big implications: "A lower-than-expected land carbon sink would also imply that the land biosphere may be closer to transitioning from a net carbon sink to a net source than current models predict" Randerson et al. www.science.org/doi/10.1126/...

"Yet, we document that for large-scale offsetters in the airline industry, carbon credit purchases competed with financing internal decarbonisation measures." I wonder what those measures are in the aviation industry. www.nature.com/articles/s41...

Can’t say I’ve ever seen an Ocean Heat Blob this intense & vast, over the entirety of the Pacific basin - the marine heatwave is literally from coast to coast. It’s remarkable. Since May the record heat has now migrated to US West Coast. Note: the Tropical Pacific is cooling (La Nina forming)

”Emissions from the wealthiest 10% in the United States and China led to a two- to threefold increase in heat extremes across vulnerable regions.” #Inequality www.nature.com/articles/s41...

Canada’s out-of-control wildfire crisis in six charts. Important new analysis from @nationalobserver.com's @bsaxifrage.bsky.social 👇 www.nationalobserver.com/2025/09/03/a...

Witnessing the rapid and extensive thawing of permafrost in Svalbard is truly impressive but deeply concerning

Final comparison. The radiative forcing from increasing greenhouse gases (CO2, CH4, CFCs, N2O etc.) and other effects is around 3 W/m2 since the pre-industrial. That is 30x the impact of the direct heat released by our use of energy.

But it worse than that. ~60% primary energy from fossil fuels is just wasted. Solar can reduce that substantially, so the ratio of useful energy from the sun to current use is closer to 7000x current use. A claim that it is only 20%, is 5 orders of magnitude wrong. Err.. Wright.

BC has 64 out of control wildfires burning and many of these are burning intensely. GOES-West 3.9 micron band (sensitive to high temperatures from wildfires) loop below showing active fires (white) and very active fires (red)

Numerous large and active fires in central BC producing large smoke flumes. GOES- West geocolor below.

We’re filling the atmosphere with CO2 like a bathtub with water. Most of it stays for millennia. That is why the cumulative emissions (the total amount, as pictured here) and not yearly emissions determine the amount of #globalwarming.

Turns out climate-driven wildfires are reversing air quality improvements in recent years. www.businessgreen.com/news/4518256...

So Carney put the former head of trans mountain - a 40+ billion boondoggle- in charge of major projects?! Carney keeps on giving fossil fuel interests exactly what they want, with no hint of a climate plan As the country keeps burning, he's lighting the matches www.ctvnews.ca/politics/art...

For no particular reason, here's the breakdown of the Senate's vote to confirm RFK Jr. to lead HHS. Every Republican but one -- Mitch McConnell -- voted to put a guy notorious for pushing dangerous lies and disinformation about vaccine safety into this job. www.senate.gov/legislative/...

The wildfires that raged across Greece, Turkey and Cyprus this summer were 22% more intense and 10 times more likely than they would have been in a world without climate change.

It is no longer a theoretical possibility that polluters could be held responsible in court — it is a real and rising legal tide, writes Senotor Rosa Galvez www.nationalobserver.com/2025/08/25/o...

Latest report from me below, and here's the Guardian's coverage (thanks to the environment team for covering it). Current policy won't deliver the emissions reductions from transport needed by 2030 and risks widening inequality. Prioritising fairness is the key to unlocking faster climate action.

The U.S. North Atlantic sea surface temperatures were as high as 32.8°C on August 24, 2025. The image shows heat moving north along the path of the Gulf Stream toward the Arctic, threatening to cause more loss of sea ice and permafrost. arctic-news.blogspot.com/2025/08/extr...

@aradwanski.bsky.social when you say this "may align BC as neatly as anywhere else in the country with the balancing act that PM Carney is attempting" would that be its magical thinking? 'Cause there's nothing coherent about this from a climate perspective. www.theglobeandmail.com/business/art...

We’re deeply disappointed negotiations for a global plastics treaty have ended without a final agreement. Over the past 3 years, the momentum has been undeniable. The world now understands, plastic is a full lifecycle problem that demands systemic solutions, & that its health impacts are profound.

"Our findings are consistent with many recent studies from across temperate and boreal regions globally, which have shown a trend of increasing area burned and wildfire severity in response to increasing aridity and worsening fire weather." 🌍
