Earth is fighting a laser duel with the exploding Carina Nebula

Home News Science & Astronomy Lasers fly through space toward the glowing Carina Nebula (Image: © ESO/G. Hüdepohl) Four orange laser beams blaze through the Milky Way while an angry purple nebula transfixes us with its death-stare. Happily (or sadly, depending on how much news you’ve consumed this week), Earth is not doomed; in fact,…Continue Reading

Food production alone is set to push Earth past 1.5°C of warming

Environment 5 November 2020 By Ibrahim Sawal Corn harvesting in Pskov, RussiaHans Neleman/Getty ImagesGreenhouse gas emissions from global food production will be enough to push Earth beyond an internationally agreed goal of limiting global warming to 1.5°C, even if we cut all other sources of emissions. “If we don’t change what we do with food,…Continue Reading

Earth may get a new minimoon — but it may just be 1960s space junk

Home News Spaceflight Every once in a while, orbital trajectories and fate’s gravity conspire to let Earth briefly adopt a miniature moon to join us for a few measures of our planet’s constant dance around the sun.Scientists rarely get to watch the process in action, but now they think they’ve spotted something that will slip…Continue Reading

Earth may have been born wet

(Image: © NASA/NOAA) Earth may not have needed asteroid and comet strikes to fill its oceans, a new study reports.Conventional wisdom has long held that our planet was born dry, because its building blocks…Continue Reading

Starting today, we have used every last natural resource the Earth can provide in a calendar year and now we live on green credit.This year, Earth Overdraft Day occurs on August 22. It marks the imaginary point at which humanity’s demand exceeds what the Earth can regenerate in that year.The international research organization Global Footprint…Continue Reading

Scientists are narrowing in on the answer. At the dawn of the industrial revolution, the Earth’s atmosphere contained 278 parts of CO₂ per million. Today, after more than two and a half centuries of fossil fuel use, that figure is around 414 parts per million (ppm). If the build-up of CO₂ continues at currentContinue Reading

In a new study, published in the journal Nature, an international team of scientists provide the first conclusive evidence directly linking deep Earth’s water cycle and its expressions with magmatic productivity and earthquake activity. Water (H2O) and other volatiles (e.g. CO2 and sulphur) that are cycled through the deep Earth have played a key role…Continue Reading
