Net-Zero Emissions: Winning Strategy or Destined for Failure?
Net-zero emissions balancing emissions by absorbing equivalent amounts of CO2 from the atmosphere is the defining approach of international climate efforts. But some scientists are arguing that this strategy simply allows the perpetuation of the status quo and is certain to fail.
Net zero. Those two words have become the near-universal language for policymakers intent on sealing a deal at the UN climate conference in Glasgow, Scotland in November. But are they the key to fulfilling the promises to hold warming to 1.5 degrees made at a similar climate summit in Paris six years ago, or, as some scientists and activists are now saying, are they a dangerous delusion to which climate scientists have become complicit?

In this image from a microscopy video, scientists “listen” to macrophages as they responded to an immune threat.
UCLA life scientists have identified six “words” that specific immune cells use to call up immune defense genes an important step toward understanding the language the body uses to marshal responses to threats.
In addition, they discovered that the incorrect use of two of these words can activate the wrong genes, resulting in the autoimmune disease known as Sjögren’s syndrome. The research, conducted in mice, is published this week in the peer-reviewed journal Immunity (Cell Press).
