THIS is what Earth may look like in the future; NASA reveals planet, climate change
Researchers at NASA have been looking into the evolution of plate tectonics on Earth, its slower rotation rate, and the Sun’s increased brightness to predict planet's terrestrial future as well as chart climate change.
Scientists have designed several models to predict the Earth's future climate. One set of researchers have explored Earth's deep-time future climate by looking at the increasing rates of carbon dioxide and solar insolation over time while others are looking into the effects on climate change brought about by changes in topography. They have discovered that while high altitude land on Amasia would lead to the creation of ice sheets, the white supercontinent would reflect back more of the Sun's heat. And the lack of a northern polar ocean would mean that more ice would be present on land and in lakes through the year near the North Pole like it is in present-day Antarctica. On the other hand, in Aurica, there would be little snow or ice with average temperatures hovering around 20 degrees Celcius.
"The geological formations on the ever-changing surface of the Earth have a strong influence on our climate," the researchers said citing how the Himalayas, created by the collision of the India-Eurasia plates, help monsoon climatic conditions.
Studying these climatic changes based on topographic movements also helps astronomers predict a climate model of an Earth-like exoplanet using parameters that are known to sustain habitability and a stable biosphere. "Using the deep-time future Earth as a basis for exoplanetary climate studies allows us to establish sensitivity ranges for the habitability and climate stability of the future Earth and its distant cousins in our galaxy," the paper said.
