Researchers find that shifts in Earth’s orbit can trigger abrupt climate changes, even in warm periods without ice sheets.

Climate tipping points are thresholds within Earth’s climate system beyond which change becomes self-reinforcing and, in some cases, irreversible on human timescales. Rather than unfolding gradually, ...

The earth (and humanity) would be very different without our smaller red neighbor. In A Nutshell Computer simulations show ...

"Without Mars, Earth's orbit would be missing major climate cycles. What would humans and other animals even look like if Mars weren't there?" ...

Earth’s slow axial wobbles—known as precession cycles—do not just shape long-term climate trends. A new study led by ...

New simulations show Mars plays a key role in shaping Earth’s long-term climate by influencing its orbit and axial tilt over hundreds of thousands to millions of years.

Marine “snow”? Yes, marine “snow,” but not the kind of snow we get here in the North Country. According to NOAA — the National Oceanographic and Atmospheric Administration: “As plants and animals near ...

New research reveals the extent to which Mars is quietly tugging on Earth’s orbit and shaping the cycles that drive long-term ...

For many years, scientists believed rising CO₂ levels would help Earth’s plants significantly slow climate change. As carbon ...
