"There is a 7% chance that 2025 will rank as the warmest year on record."

"It's unlikely 2025 will be as hot as 2024."

"Years such as 2025 which aren't dominated by the warming influence of El Niño, should be cooler."

"2025 will be moderately cooler than 2024."

"It is likely that 2025 will not be as hot as recent years."

"Don't count 2025 out in the race for hottest year."

"The global mean temperature in 2025 is expected to surpass the earlier record set during the exceptionally strong 2014-2016 El Niño."

"The high January temperatures have increased the odds of 2025 being the warmest year on record."

"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."

"[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."

According to a study published in Communications Earth &amp; Environment on Tuesday, ice sheets in Greenland and Antarctica are melting four times faster than in the 1990s, losing approximately 370 billion tons of ice annually at just 1.2°C of global warming above pre-industrial levels.

Scientists analyzed three types of evidence: satellite observations, past climate records, and computer models. According to lead author Chris Stokes, when CO2 levels were similar to today's about 3 million years ago, sea levels were 10-20 meters higher than present.

Current projections indicate that even if global warming is limited to 1.5°C, sea levels could rise by 1 centimeter per year by the end of the century, and potentially cause annual flood damages of $1 trillion to the world's 136 largest coastal cities by 2050.

Stokes, a professor at Durham University in England, warned that even if global warming is limited to 1.5°C, "sea level rise is likely to accelerate to rates that are very difficult to adapt to."

The study, led by Durham University, UK, suggested that the average global temperature should be closer to 1°C to avoid significant losses from the melting polar ice sheets and prevent a further acceleration in sea level rise.

Approximately 230 million people live within one meter of sea level, and 1 billion reside within 10 meters above sea level. Scientists warn that melting ice makes them vulnerable to rising seas and potential displacement.

While the situation is serious, focusing on tipping points can distract from the fact that every fraction of a degree of warming avoided matters significantly. The 1.5C target remains crucial as it would still allow more time for adaptation and reduce the rate of sea level rise compared to higher temperature scenarios. Continued technological and infrastructure development could help coastal communities adapt to moderate rises.

The current global climate target of 1.5°C is dangerously inadequate for protecting coastal communities. Recent satellite observations show unprecedented ice loss that far exceeds previous model predictions, indicating we're already witnessing worst-case scenarios unfold. Without immediate and drastic action to reduce temperatures below current levels, coastal cities face inevitable inundation and massive population displacement.
