Climate Change Could Heat the Earth Right Into a New Ice Age: What You Need to Know
Could climate change push Earth toward an ice age? Scientists have long debated how Earth’s climate will evolve over centuries and millennia. While much attention centers on rising temperatures and extreme weather, some researchers explore a paradox: could certain natural processes trigger a cooling trend strong enough to approach a new ice age? The answer…

Could Climate Change Drive Earth Toward a New Ice Age?
Introduction: A provocative idea with historical context Climate historians know Earth has endured dramatic swings long before humans learned to emit greenhouse gases. The planet’s long arc has included warm intervals and icy chapters, driven by a mix of natural cycles and geological processes. Some researchers now ask a surprising question: could the combination of…

CO2 Rise and Ionosphere: Threat to Space Communications
Rising CO2 and a Cooling Upper Atmosphere: Why Space Communications Could Be at Risk As global warming accelerates, researchers are turning their attention to how atmospheric changes affect the ionosphere, a region roughly 60 to 1,000 kilometers above Earth. A team from Kyushu University has found that higher carbon dioxide (CO2) levels, while warming Earth’s…

Rising CO2 Could Disrupt Space Communications via Sporadic-E Ionosphere Changes
Overview: A Climate Link to Space-Weather Disruptions As the planet warms, researchers are uncovering how rising carbon dioxide (CO2) levels may extend their influence beyond the surface. A team from Kyushu University has reported that higher CO2 concentrations can cool the ionosphere, a region about 100 kilometers above Earth’s surface where charged particles interact with…

JWST Sheds Light on Trapped CO2 Across Saturn’s Satellites
Overview The James Webb Space Telescope (JWST) has opened a new window into the chemistry of the outer solar system by detecting solid state carbon dioxide (CO2) on eight mid-sized Saturnian satellites. Spanning moons inside and outside the Iapetus–Phoebe region, these observations illuminate how CO2 can be trapped in various host materials at temperatures where…

Cooler warm periods: How the Southern Ocean controlled climate and atmospheric CO2
Introduction: A long-standing climate puzzle For millions of years, the Earth’s climate oscillated between frigid glacial periods and warmer interglacials. Among these, the so-called lukewarm interglacials, spanning roughly from 800,000 to 430,000 years ago, are particularly intriguing. During these warmer phases, atmospheric CO2 hovered around 240–260 ppm, with later interglacials reaching 280–300 ppm. Today, CO2…

JWST Study of CO2 on Saturn’s Satellites Reveals Varieties
Introduction The James Webb Space Telescope (JWST) is pushing the frontiers of planetary science by analyzing the composition of bodies far from Earth. A new study using JWST spectra investigates carbon dioxide (CO2) on eight mid-sized Saturnian satellites, from the inner moons Mimas, Enceladus, Tethys, Dione, and Rhea to the outer ones Hyperion, Iapetus, and…

Cooler warm periods: How the Southern Ocean shaped climate and CO2
New insights into a long-standing climate question Earth’s climate has long swung between cold glacial states and warmer interglacial periods. Among these, the so-called lukewarm interglacials—warm phases that occurred roughly between 800,000 and 430,000 years ago—stand out for their relatively cool temperatures and modest atmospheric CO2 levels (about 240–260 ppm). Even the later interglacials, which…

Sophie Hermans Tata Steel deal: Dutch government under fire
The deal at a glance In a move that has sparked intense political debate, demissionary minister Sophie Hermans announced a 2‑billion-euro package to shore up a major steel producer. Proponents argue the funding safeguards jobs and regional investment, while critics contend the terms do not deliver meaningful improvements on health, workers’ rights, or environmental safeguards.…
