Every plant alive today, from the tallest rainforest tree to the smallest patch of moss, will eventually disappear, but a new scientific study suggests that moment is much further away than most previous research believed. Researchers Jacob Haqq-Misra of the Blue Marble Space Institute of Science and Eric Wolf of the University of Colorado Boulder have calculated that Earth's vegetative biosphere could continue supporting plant life for roughly another 1.8 to 1.87 billion years, considerably longer than earlier estimates that put the number closer to 0.9 to 1.5 billion years. The extended timeline comes down to a more sophisticated understanding of exactly how a slowly brightening sun and a shrinking supply of atmospheric carbon dioxide will eventually make the planet uninhabitable for any
