How TIMED flies: Unexpected trends in carbon data

NASA's TIMED mission, short for Thermosphere, Ionosphere, Mesosphere Energetics and Dynamics, has confirmed a surprisingly fast carbon dioxide increase in Earth's upper atmosphere, raising questions about how different layers ...

Atmospheric CO2 drove climate change during longest interglacial

Known as the marine isotope stage 11 (MIS 11), the interglacial period centered around 400,000 years ago was the longest and possibly the warmest interglacial in the past 0.5 million years. Because the orbital configurations, ...

Replacing coal with natural gas would reduce warming: study

A debate has raged in the past couple of years as to whether natural gas is better or worse overall than coal and oil from a global warming perspective. The back- and-forth findings have been due to the timelines taken into ...
