Earth's Carbon Cycle May Trigger an Ice Age Amid Global Warming

New research suggests that Earth's climate regulation involves complex ocean feedback loops that could overcorrect global warming, potentially triggering an ice age in the distant future, although current human-induced warming is unlikely to cause such a rapid cooling. The study highlights the importance of understanding Earth's natural climate mechanisms and emphasizes the need to limit ongoing warming.

Did a Passing Star Trigger Earth's 56-Million-Year Warming?

Recent research suggests that passing stars, or stellar flybys, did not influence Earth's climate over the past 56 million years, including during the Paleocene-Eocene Thermal Maximum, when significant global warming occurred. Advanced models incorporating comprehensive Solar System dynamics show no link between stellar flybys and climate shifts, challenging earlier hypotheses that such events triggered major climatic changes.

Stellar Flybys and Their Impact on Earth's Climate History

Recent research suggests that stellar flybys have likely not influenced Earth's past climate changes over the last 56 million years, challenging earlier hypotheses. Using comprehensive solar system models, scientists found no significant impact of passing stars on Earth's orbital stability or climate events like the Paleocene-Eocene Thermal Maximum, emphasizing the importance of detailed modeling in understanding celestial influences on our planet.

"Interstellar Visitors: How Passing Stars Changed Our Solar System's Orbits"

Astronomers have found that passing stars have significantly impacted the long-term orbital evolution of Earth and other planets, leading to uncertainties in predicting past orbital behavior. These stellar encounters alter the gravitational perturbations on the giant planets in our solar system, subsequently affecting Earth's orbital trajectory and potentially influencing ancient climate anomalies. The study highlights the importance of considering passing stars in astronomical simulations to improve our understanding of Earth's orbital history and its connection to past climate variations.

Unveiling the Terrifying Dynamics of Earth's Runaway Greenhouse Effect

Researchers have successfully simulated all stages of a runaway greenhouse effect, revealing that a small increase in solar irradiation could turn Earth into an uninhabitable planet similar to Venus. The study, conducted by astronomers from the University of Geneva and supported by France's CNRS laboratories, aimed to provide insights into climate on other planets and the potential risks to Earth's climate in the future. The researchers found that a slight increase in global Earth temperature could trigger an irreversible runaway process, leading to the evaporation of oceans and temperatures reaching several hundred degrees. They warned that Earth is not far from an "apocalyptical scenario" if global temperatures rise beyond 1.5 °C above preindustrial levels.
