In a recent NOAA briefing, researchers omitted any mention of the link between January’s record high global temperatures and human-caused greenhouse gas emissions, a departure from previous practices. This omission occurred despite the briefing acknowledging record-high temperatures and despite direct questions about the role of climate change. The head of NOAA’s monitoring branch cited factors such as reduced air pollution and cloud cover as potential explanations, but this explanation fails to account for the overall warming trend. This silence comes amidst increased scrutiny of US scientific agencies under the Trump administration and a broader effort to downplay the role of climate change in government reports and communications.

A University of Reading study reveals a dramatic acceleration in global mean sea surface temperature (GMSST) rise, increasing 400 percent faster than in the late 1980s. This escalating warming, driven by Earth’s energy imbalance from greenhouse gas emissions, shows that the warming of the past 40 years will likely be surpassed in under 20 years without significant emission reductions. Recent record ocean temperatures, even accounting for El Niño, underscore this alarming trend, highlighting the urgent need for deep cuts in fossil fuel use. The study, published in *Environmental Research Letters*, emphasizes that past warming rates are unreliable predictors of future, more rapid changes.

New research by Professor James Hansen suggests the pace of global heating has been severely underestimated, rendering the 2°C target unattainable. This conclusion stems from findings that both the impact of reduced shipping pollution and climate sensitivity to increased emissions are higher than previously believed. These results, while at the high end of current estimates, cannot be dismissed and indicate a significantly accelerated warming trajectory, potentially triggering critical tipping points like the collapse of the Atlantic ocean currents. Unless drastic action is taken, including potentially exploring solar geoengineering, the study projects a 2°C rise by 2045.

Unprecedented warming in the Arctic saw temperatures exceeding 20°C above average on Sunday, surpassing the melting point of ice. This extreme event, linked to a low-pressure system over Iceland and unusually warm seas, resulted in temperatures near 0°C at 87°N latitude. While the exact anomaly is difficult to pinpoint due to limited data in the region, models consistently show a significant temperature increase, highlighting the accelerated warming trend in the Arctic. This rapid warming, nearly four times faster than the global average, poses a significant threat to Arctic sea ice, with its complete summer melt predicted within the next two decades.

President Trump’s executive order formally withdraws the United States from the Paris Agreement, a 2015 accord committing nearly 200 nations to curbing global warming. This decision, defying overwhelming scientific consensus, ignores the escalating climate crisis evidenced by record-breaking temperatures in 2024. The agreement aimed to limit global temperature increases to 1.5-2 degrees Celsius above pre-industrial levels, a goal now further jeopardized by this withdrawal. Critics argue the move demonstrates a disregard for both domestic and global consequences of climate change.

Atmospheric CO2 levels surged to a record 3.58 ppm increase in 2024, exceeding predictions and driven by record fossil fuel emissions, diminished carbon absorption by natural sinks, and significant wildfire emissions. This rapid increase far surpasses the rate needed to meet the Paris Agreement’s 1.5°C warming target, as outlined by the IPCC. The 2024 increase in emissions, reaching 41.6 billion tonnes, further underscores the urgency of emissions reduction. While the projected increase for 2025 is slower, it remains insufficient to align with the IPCC’s climate goals.

2024 marks the first year to exceed the symbolic 1.5°C global warming threshold above pre-industrial levels, according to Copernicus Climate Service data, making it the hottest year on record. This surpasses the previous record set in 2023 by over 0.1°C, highlighting a concerning trend of escalating global temperatures. While this does not represent a breach of the long-term 1.5°C target agreed upon in Paris, it brings the world significantly closer to that critical threshold. The increased warming is primarily attributed to human emissions of greenhouse gases, exacerbated by natural weather patterns like El Niño, underscoring the urgent need for emission reductions.

The Arctic is changing, and these changes are deeply concerning. Scientists are observing dramatic shifts in the region’s ice and weather patterns, and these aren’t isolated incidents; they represent a cascading effect with global implications. The melting ice caps are a stark visual representation of the problem, and the implications extend far beyond just rising sea levels.
The lack of widespread, urgent action is baffling and disheartening. It feels as if the world is sleepwalking towards a precipice, lulled by complacency and a prioritization of short-term gains over long-term survival. The alarm bells should be ringing incessantly, yet the response has been muted, suggesting a profound disconnect between the urgency of the situation and the actions (or lack thereof) of those in power.… Continue reading
2024 is being declared the hottest year on record by EU scientists, a stark reminder of the escalating climate crisis. This isn’t just a new record; it’s a continuation of a trend, with each year seemingly surpassing the last. The sheer repetition of this announcement, year after year, highlights the urgency of the situation.
The disheartening reality is that this record-breaking heat is likely to be surpassed again in 2025, and the year after that, and so on. This isn’t a matter of scientific uncertainty; the data consistently points towards a warming planet. The question is no longer *if* temperatures will continue to rise, but rather how we, as a global society, will adapt and mitigate the consequences.… Continue reading
Over 450 polar researchers, including a significant number of early career scientists, recently released a statement emphasizing the urgent need for climate action in Antarctica. The statement highlights unprecedented changes, including record-low sea ice, extreme heatwaves, and ice shelf instability, threatening catastrophic sea level rise. East Antarctica’s melting ice sheet poses a particularly significant, yet uncertain, threat to global sea levels. The researchers call for immediate greenhouse gas emission reductions to avoid irreversible tipping points and protect coastal communities.
