"2023 is proving to be a year of climate and weather extremes. Record-busting
global air and ocean temperatures, unprecedented low levels of Antarctic sea
ice, and devastating fires and floods have been reported across the world.
Less discussed by the world media is the continuing rise in atmospheric
greenhouse gases driving these changes. Carbon dioxide (CO₂) is at a level not
seen since the hothouse world of the Pliocene, 3 million years ago. On top of
that, an El Niño event is now likely, so widespread extreme events may
intensify in coming months.
Despite the changes we are seeing, global efforts to cut emissions fall well
short of what’s needed to keep heating to less than 2°C, let alone the more
ambitious Paris Agreement target of 1.5°C. This creates an urgent need for the
purposeful removal of atmospheric CO₂ as well as cuts in emissions.
In a recent article in
Nature, we argue for a different approach to pricing
carbon. It should take into account how it is removed from the atmosphere, for
how long, and with what confidence. This will help fund the most promising
technologies for reaching net-zero carbon emissions by 2050."
