One only need look outside the window to understand that human-caused climate disruption is in overdrive.
Record warm temperatures, floods, droughts, wildfires and increasing incidents of extreme weather events have run rampant across the Northern Hemisphere this summer. These events, at least in part, stem from a global temperature increase of “only” 1 degree Celsius (1°C) above preindustrial baseline temperatures.
MIT and Harvard-trained scientist Dr. Thomas Goreau, a climate and coral reef expert, put this in stark perspective.
“Today’s carbon dioxide levels at 400 parts per million (ppm) [are] akin to bringing about a steady state temperature of 7°C higher and sea levels 23 meters higher than they are today,” Goreau, who is also president of the Global Coral Reef Alliance and coordinator of the Soil Carbon Alliance, told Truthout. In other words, the last time there was this much carbon dioxide in the atmosphere, it increased the Earth’s temperature to a point 7°C higher than it is today, and increased sea levels 23 meters above their current level. Hence, we are now only waiting for the planet to catch up to what we’ve done to the atmosphere.
More than three decades ago, Goreau and some of his colleagues were already pointing out that the only way runaway global warming could be avoided was by utilizing and expanding carbon sinks – a natural or artificial area where carbon is stored — as a way of sequestering carbon dioxide from the atmosphere.
Despite this not happening on the scale necessary to avert widespread impacts of runaway climate change, Goreau, along with many others, is as determined as ever to utilize various methods of “eco-restoration” to draw carbon out of the atmosphere.
