A new report examining more than a dozen of the Earth’s life-sustaining systems paints a pretty bleak picture. Published last week in BioScience, the seventh annual State of the Climate report shows how global warming is producing significant shifts in the planet’s overall health and destabilizing the climate as a whole.

Key climate indicators are going in the wrong direction: greenhouse gas emissions, sea level rise, glacier thickness, ice mass, and more. These shifts should no longer be taken as warning signs about some distant future, the authors write; instead, they amount to a “diagnosis” of how climate change is impacting the planet today — and where things will go if human behavior doesn’t change quickly or sufficiently enough.

Concentrations of carbon dioxide, methane , and nitrous oxide, stemming primarily from the burning of fossil fuels, hit record highs this year. Meanwhile, glacier thickness and Greenland ice mass are at record lows.…
