Critically, scientists have now confirmed that the ocean in recent decades has continued its steadfast rate. carbon dioxide levels aren’t just abnormally high, but today’s accelerated pace of heat.
New findings released on Wednesday show that at current emissions rates, we’re just five generations away from creating an atmosphere the likes of which hasn’t been seen in 56 million years. The last time carbon dioxide levels were as high as we’re headed for, it helped create one of the greatest die offs in recent Earth history.
An enhanced greenhouse effect from CO2 has been confirmed by multiple lines of empirical evidence. Good scientific theories are said to have ‘predictive power’. In other words, armed only with a theory, we should be able to make predictions about a subject. If the theory’s any good, the.
