"[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 Wageningen University analyzed 385 peer-reviewed studies on coastal vulnerability published between 2009 and 2025, finding that approximately 90 percent failed to incorporate direct sea level measurements and instead relied on geoid models that underestimated coastal water heights.

The studies underestimated baseline coastal sea levels by an average of 24 to 27 centimeters globally, with discrepancies reaching up to 1 to 1.5 meters in parts of Southeast Asia and the Indo-Pacific, according to research published in the journal Nature.

Geoid models estimate sea level based on Earth's gravitational field and rotation but do not account for factors such as ocean currents, winds, tides, temperature and salinity that influence actual sea levels at coastlines.

The corrected baseline measurements indicate that with a one-meter sea level rise projected by 2100, up to 37 percent more coastal land could be submerged, potentially affecting between 77 million and 132 million additional people worldwide.

Forty-six of the evaluated studies were cited in the Intergovernmental Panel on Climate Change's Sixth Assessment Report, raising concerns about the accuracy of global climate impact assessments used by policymakers.

Scientists recommend installing more tide gauges in lower-income countries and combining satellite measurements with local sea level data to improve coastal risk assessments, particularly in regions where gravitational data for geoid models is sparse.
