If Earth were a human, it would already be in the emergency room.

An international team of scientists on Tuesday issued a new assessment of planetary health that says the world has entered uncharted climate territory and that life on planet Earth is under siege.

The report, published in the journal BioScience, found that 20 of 35 identified vital signs of the planet from human population and greenhouse gas emissions to sea level rise and ocean acidity have reached record extremes.

The analysis, authored by a dozen expert scientists, is as much a desperate warning as an urgent call for action.

For several decades, scientists have consistently warned of a future marked by extreme climatic conditions because of escalating global temperatures caused by ongoing human activities that release harmful greenhouse gasses into the atmosphere, the report states. Unfortunately, time is up. We are seeing the manifestation of those predictions as an alarming and unprecedented succession of climate records are broken, causing profoundly distressing scenes of suffering to unfold. We are entering an unfamiliar domain regarding our climate crisis, a situation no one has ever witnessed firsthand in the history of humanity.

This year has truly been one of extremes unprecedented heat waves, record-shattering land and sea surface temperatures, record-low Antarctic sea ice extent, and a Canadian wildfire season that has so far torched over 45 million acres, more than 2.5 times the previous record.
