To assist with local weather change, carbon seize should evolve

Greater than 200 kilometers off Norway’s coast within the North Sea sits the world’s first offshore carbon seize and storage venture. In-built 1996, the Sleipner venture strips carbon dioxide from pure fuel—largely made up of methane—to make it marketable. However as an alternative of releasing the CO2 into the environment, the greenhouse fuel is buried.

The hassle shops round 1 million metric tons of CO2 per yr—and is praised by many as a pioneering success in world makes an attempt to chop greenhouse fuel emissions.

Final yr, complete world CO2 emissions hit an all-time excessive of round 35.eight billion tons, or gigatons. At these ranges, scientists estimate, now we have roughly six years left earlier than we emit a lot CO2 that world warming will constantly exceed 1.5° Celsius above common preindustrial temperatures, an internationally agreed-upon restrict. (Notably, the worldwide common temperature for the previous 12 months has exceeded this threshold.)
