Why Do We Think Pangea Wi Happen Again

New research presented at the annual meeting of the American Geophysical Matrimony highlights the future of our continents – a future which suggests renewed unity, quite literally. Only every bit our continents were once all connected in the supercontinent known equally Pangea (which separated roughly 200 million years ago), scientists predict that in approximately 200-250 million years from now, the continents will once again come together. But what volition that wait like?

While scientists aren't entirely certain, there are some thoughts that a supercontinent could form effectually the north pole, encompassing all of the continents save Antarctica. An alternative could look like a supercontinent composed of all the continents that meet well-nigh the equator. As to what these it would exist similar to live on these supercontinents, there'due south still a lot up for imagination. Just that's what researchers led by Michael Way at the NASA Goddard Institute for Space Studies are contemplating.

Way and his inquiry team have used the forward evolution of plate tectonics, solar luminosity, and rotation charge per unit to model what the climate would look similar on the two potential supercontinents named respectively "Amasia" and "Aurica".  In the example of Amasia, with the continents surrounding the northward pole except for Antarctica, the supercontinent would experience much colder temperatures with ice cover throughout the year. Sea level would as well likely be lower due to the more water beingness independent in ice caps.

With Amasia, "you go a lot more than snowfall," says Way. "Yous get water ice sheets, and y'all go this very effective ice-albedo feedback, which tends to lower the temperature of the planet." This is because the absence of country in the oceans disturbs the ocean currents that are responsible for moving heat from the equator to the poles.

In the scenario with the Aurica supercontinent, on the other hand, at that place would be the opposite effect. More than landmass effectually the equator would absorb more rut and spur higher temperatures, in function also because of the absence of polar water ice caps. With Aurica, the planet could end upward being iii degrees Celsius hotter.

"The climate differences between these two scenarios are dramatic, with differences in mean surface temperatures budgeted several degrees," write the authors. Their findings are useful in thinking about not only the futurity of our ain planet but also the existence of life on other planets. They point toward the need to contemplate how landmass arrangements influence the availability of h2o in sure scenarios, a factor not often considered in the search for other life. "These results demonstrate that using a uncomplicated aquaplanet or a modern Earth country/body of water mask is not sufficient to explore the possible variance in theoretical modeling of extrasolar planetary atmospheres," the authors conclude.
