Thwaites Glacier could shed 200 gigatonnes of ice annually by 2067, raising sea levels and fueling collapse fears

Scientists warn that Antarctica’s Thwaites Glacier could lose about 200 gigatonnes of ice per year by 2067, potentially adding around 0.5 mm to global sea‑level rise annually and accelerating toward collapse. The findings, based on satellite‑calibrated ice‑sheet models, show that melting is five times faster than in the 1990s and concentrates in deep bedrock valleys inland. While a total collapse isn’t considered imminent, the study suggests a rapid retreat could occur within a couple of centuries under current emissions, with significant delay possible if greenhouse gas emissions are cut.

Planet warming accelerates: new study finds acceleration since 2015

A study published in Geophysical Research Letters finds that global warming has accelerated since 2015, with Earth warming about 0.35°C in the last decade—faster than the roughly 0.2°C per decade observed from 1970 to 2015. If this pace continues, the 1.5°C Paris target could be breached before 2030, underscoring the urgency of reducing CO2 emissions.

New study finds global warming is accelerating, raising chances of hitting 1.5°C sooner

A new paper in Geophysical Research Letters reports that Earth's warming has accelerated significantly in the last decade (about 0.35°C per decade from 2015–2025, up from ~0.2°C/decade 1970–2015), suggesting the 1.5°C limit could be breached earlier than expected if the trend continues. While multiple datasets show the acceleration, some scientists disagree, noting that recent warming could reflect natural variability or the end of aerosol cooling, and stressing the need for continued monitoring to confirm a lasting shift.

Unprecedented Earth Tilt Raises Concerns

A new study published in Geophysical Research Letters reveals that pumping groundwater has caused Earth's tilt to shift by 31.5 inches in less than two decades, resulting in a sea-level rise of 0.24 inches. The redistribution of groundwater has been found to have the largest impact on the drift of the rotational pole, surpassing other climate-related causes. The study highlights the significant influence of human activities on Earth's rotation and emphasizes the need for better understanding and management of groundwater pumping to mitigate the effects of climate change, including sea-level rise.

The Alarming Shift: Humans Alter Earth's Axis

A new study published in Geophysical Research Letters reveals that pumping groundwater has caused Earth's tilt to shift by 31.5 inches in less than two decades, resulting in a sea-level rise of 0.24 inches. The redistribution of groundwater has been found to have the largest impact on the drift of the rotational pole, surpassing other climate-related causes. The study highlights the significant influence of human activities, particularly irrigation, on Earth's rotation and climate change. Understanding the effects of groundwater pumping can aid in mitigating sea-level rise and other climate issues.

"Unprecedented Lightning Storm Unleashed by Volcanic Eruption"

The eruption of the underwater volcano Hunga Tonga-Hunga Ha'apai triggered the most intense lightning storm ever recorded, according to a study published in Geophysical Research Letters. The eruption sent millions of tons of ash, dust, and superheated water into the atmosphere, creating an umbrella cloud. Lightning strikes occurred at an unprecedented rate, with approximately 2,600 strikes per minute during the peak. The lightning also occurred at significantly higher altitudes than usual, suggesting that volcanoes can create their own weather systems.
