Relentless carbon is shrinking Earth’s upper atmosphere, scientists warn

Rising levels of carbon dioxide in Earth’s atmosphere could exacerbate efforts to clean our increasingly cluttered shell of orbiting space debris. Greenhouse gas has contributed significantly to the contraction of the upper atmosphere, according to two new studies. This contraction has been assumed for decades; now, for the first time, this has actually been observed. …

New maps of ancient warming reveal strong response to carbon dioxide

Enlarge / World map of the evolution of precipitation due to warming 56 million years ago: green = wetter, brown = drier. The circles show where the geologic data shows it has gotten drier or wetter, to verify the new results. Tierney and. Al. In a study published in PNAS, University of Arizona Professor Jessica …
