"[C]limate change is just a very, very expensive form of tax."

"I believe in climate change caused by human beings. What I'm skeptical about is the glib notion that it means the end of the world as we know it."

"The clock is no longer just ticking, it is banging."

"There is no long-term prosperity without action on climate change."

"The time for seeking global solutions [to climate change] is running out."

"The climate crisis is the existential threat. That's not hyperbole; it's a fact."

"[W]e are killing our planet."

Climate change is "above all, an existential crisis."

"Climate change is one of the greatest challenges mankind faces."

"If we don't take action, the collapse of our civilisations and the extinction of much of the natural world is on the horizon."

"Humanity is on thin ice — and that ice is melting fast."

"We haven't yet exceeded the bounds of viable human civilisation, but we're getting close."

"At this point it is virtually certain we will blow through [the 1.5C] target."

'"On our current path... we will reach that 1.5-degree limit sometime in the 2030s."

"Without immediate and deep emissions reductions across all sectors, it will be impossible [to limit global warming to 1.5C]"

"We are still nowhere near the scale and pace of emission reductions required to put us on track toward a 1.5C world."

We won't have "extreme cases like of 4 degrees [Celsius] warming," but will "miss the 2-degree goal."

"[C]utting our emissions in half in 10 years only gives us a 50% chance of staying below 1.5 degrees."

Keeping global warming to 1.5C is "entirely doable" and "simply a matter of political willpower."

Will Global Warming Be Limited to 1.5°C or "Well Below" 2°C?

Researchers from the University of East Anglia and the University of California, Merced, have found that synchronized extreme fire weather, characterized by exceptionally warm, dry and often windy conditions, has increased significantly worldwide since 1979.

Researchers from the University of East Anglia and the University of California, Merced, have found that synchronized extreme fire weather, characterized by exceptionally warm, dry and often windy conditions, has increased significantly worldwide since 1979.

In their study published Wednesday in Science Advances, the team estimates that more than half of the observed increase in synchronous fire weather is driven by human-caused climate change, while natural climate variability can strongly amplify synchronicity in some regions.

In many areas, the number of high-risk days happening at the same time has more than doubled. The continental United States averaged 7.7 synchronous fire weather days per year from 1979 to 1988, but in the last 10 years, that average rose to 38 days per year.

From 1979 through the mid-1990s, the world experienced an average of 22 synchronous fire-weather days per year — periods when extreme fire conditions occurred simultaneously across large regions of the world. By 2023 and 2024, that number had surged to more than 60 days annually.

The study found that simultaneous fire weather tends to be more strongly associated with poorer air quality in boreal regions, Equatorial Asia, Africa and South America. In Europe, population exposure to fire-sourced air pollution is almost 200% higher during years with the most synchronous fire weather days.

According to researchers, when extreme fire weather occurs across many places at once, it increases the likelihood of widespread fire outbreaks and strains firefighting capacity, because crews, aircraft, and equipment cannot be easily shared when everyone needs help at the same time.

Extreme fire weather days have nearly tripled globally since 1979, with human-caused climate change responsible for over 60% of this alarming increase. The synchronous nature of these conditions means multiple regions now face fire threats simultaneously, overwhelming suppression resources that once could be shared between areas with staggered fire seasons. South America has seen fire weather days skyrocket from 5.5 to over 70 annually, proving the climate crisis is fundamentally reshaping global fire risk.

Long-term data reveals wildfires were far more frequent before 1900, and current increases simply reflect relaxed fire suppression policies after decades of dangerous fuel accumulation. The flammability of vegetation depends on 1 to 4 days of dry weather, not climate trends requiring 30 years to detect, while 85% to 95% of fires stem from human ignitions including arson. Blaming CO2 ignores that only 6% of Earth has experienced increased aridity, with most changes driven by natural La Nina conditions rather than warming.

There's a 98% chance that there will be at least 2˚C of global warming by 2100, according to the Metaculus prediction community.
