Greenhouse gas emissions around the world exceed pre-pandemic lockdown levels – WTSP.com

After a drop in overall emissions in 2020, warming is expected to continue; and there are reasons climate experts are concerned. After declining sharply last spring, global emissions of greenhouse gases ended 2020 by exceeding pre-pandemic levels, according to International…

How much longer will the oxygen-rich atmosphere be sustained on Earth?

(Toho University ) Earth’s modern atmosphere contains copious amounts of molecular oxygen (O2), representing an important remotely detectable sign of life. However, a fundamental question of how much longer the Earth’s oxygen-rich atmosphere will persist into the far future remains uncertain. A new study finds that a highly-oxygenated atmosphere is not a permanent feature even for Earth, which has implications for the search for life beyond the solar system.

How Exactly Does Carbon Dioxide Cause Global Warming? – State of the Planet

“You Asked” is a series where Earth Institute experts tackle reader questions on science and sustainability. Over the past few years, we’ve received a lot of questions about carbon dioxide — how it traps heat, how it can have such…

Can air pollution help us find alien life?

To find alien life in our universe, scientists have considered searches for optical lasers or even giant energy-harvesting structures known as Dyson spheres. Now they’re suggesting a more mundane sort of search, a hunt for air pollution in exoplanet atmospheres.

42,000-year-old trees allow more accurate analysis of last Earth’s magnetic field reversal

(GFZ GeoForschungsZentrum Potsdam, Helmholtz Centre) The last complete reversal of the Earth’s magnetic field, the so-called Laschamps event, took place 42,000 years ago. Radiocarbon analyses of the remains of kauri trees from New Zealand now make it possible for the first time to precisely time and analyse this event and its associated effects, as well as to calibrate geological archives such as sediment and ice cores from this period. Simulations based on this show considerable effects in the Earth’s atmosphere.

Who Misses The Energy Crisis? Biden Does

The regulatory and policy changes of the Trump administration led to unparalleled job growth and national prosperity. We suffered through the dark Carter years of interrupted energy supplies, higher fuel costs, and long lines at gas stations, at the mercy of oil-rich…

NASA-funded network tracks the recent rise and fall of ozone depleting pollutants

(NASA/Goddard Space Flight Center) A short-lived resurgence in the emission of ozone depleting pollutants in eastern China will not significantly delay the recovery of Earth’s protective ‘sunscreen’ layer, according to new research published Feb. 10 in Nature.

There’s an invisible climate threat seeping from grocery store freezers. Biden wants to change that. – The Washington Post

In nearly every supermarket in America, a network of pipes transports compressed refrigerants that keep perishable goods cold. Most of these chemicals are hydrofluorocarbons — greenhouse gases thousands of times more powerful than carbon dioxide — which often escape through…
