Climate Collision Course: CO2 Levels About to Hit 400 PPM

In a first in human history, “it looks like the world is going to blow through the 400-ppm level without losing a beat.”

– Andrea Germanos, staff writer

Concentrations of CO2 are nearing 400 ppm for the first time in human history. (Credit: Scripps Institution of Oceanography) The world is likely days away from a “sobering milestone” in our planetary history.

Concentrations of the greenhouse gas carbon dioxide will likely reach 400 parts per million (ppm) for first time in human history, say scientists at the Scripps Institution of Oceanography, and unless drastic action is taken, we’re on track to hit 450 ppm in the near future.

“I wish it weren’t true, but it looks like the world is going to blow through the 400-ppm level without losing a beat,” said Scripps geochemist Ralph Keeling, whose father Charles David (Dave) Keeling began the “Keeling Curve” to track daily CO2 levels recorded at Mauna Loa Observatory.

The last time the greenhouse gases were at 400 ppm was likely the Pliocene epoch, between 3.2 million and 5 million years ago.

The current reading is at 399.72 ppm — far past the 350 ppm level many, including noted climate scientist James Hansen, have warned is the upper safe limit before the planet hits a tipping point.

“At this pace we’ll hit 450 ppm within a few decades,” warned Keeling. Indeed, the rate of rise of CO2 over the past century is “unprecedented.”

The figure should serve as a call to act on the deadly emissions caused by our fossil fuel addiction, the scientists say…..(read more).

Residents of one Canadian town are engaged in a David and Goliath-style battle over the dirtiest oil project ever known.

Filmmakers: Niobe Thompson and Tom Radford

The small town of Fort Chipewyan in northern Alberta is facing the consequences of being the first to witness the impact of the Tar Sands project, which may be the tipping point for oil development in Canada.

The local community has experienced a spike in cancer cases and dire studies have revealed the true consequences of “dirty oil”……()

If Oil Spills in A Forest, Does Anyone Clean It?

Published on Apr 23, 2013

Arkansas has been dealing with a major oil spill–one of 13 major oil spills happening in the last 30 days–spilling 1.2 million gallons of oil. But there is a media blackout surrounding the location of the disaster and the clean-up has been privatized to keep it swept under the rug. Tyrel Ventura and Tabetha Wallace of Buzzsaw shed some light on it in this clip.
