Changes in Earth’s orbit may have triggered ancient warming event

A 6,000-year onset, coupled with estimates that 10,000 gigatons of carbon were injected into the atmosphere as the greenhouse gases carbon dioxide or methane. Changes in Earth's orbit that favored hotter conditions may have helped trigger a rapid global warming event 56 million years ago that is considered an analogue for modern climate change, according to an international team of scientists. "The Paleocene-Eocene Thermal Maximum is the closest thing we have in the geologic record to anything like what we're experiencing now and may experience in the future with climate change," said Lee Kump, professor of geosciences at Penn State. "There has been a lot of interest in better resolving that history, and our work addresses important questions about what triggered the event and th...

NASA James Webb Space Telescope detects CO2 on an exoplanet! Will it have life on it?

NASA's James Webb Space Telescope has captured the first clear evidence of carbon dioxide (CO2) in the atmosphere of a planet outside of our solar system. Here is all you need to know. Earth's atmosphere is made up of mainly three gases, namely nitrogen, oxygen and carbon dioxide. But now, evidence has been found for the existence of carbon dioxide in the atmosphere of a planet outside the solar system. The evidence has been captured by Nasa's James Webb Space Telescope. Informing about the same, NASA Webb Telescope tweeted, "Catch your breath — Webb has captured the first clear evidence of carbon dioxide (CO2) in the atmosphere of a planet outside of our solar system! WASP-39 B is a gas giant closely orbiting a Sun-like sta...
