key numbers from the new climate report: 95-99%: that’s the level of certainty that scientists have that humans are causing the world to heat up. To put that into context, that’s the same level of certainty scientists have that cigarettes cause cancer. That’s what scientists call “unequivocal”. The debate on the basics of climate science is over. 1 Trillion: the global “carbon budget” in metric tons. That’s the amount of CO2 we can release into the atmosphere while keeping global warming under 2 degrees Celsius -- what many scientists have identified as a red line for our planet. We’ve already burned through about half of that carbon budget. Translation: we need action. ASAP. 1,2,3: the ranking of the last three decades in the “warmest decades in recorded history.” In other words: the planet is heating up, and we’re breaking new climate records every day.
