CO2 levels rising exponentially
Scientists’ and environmentalists’ worst nightmare has come true. Planet Earth is Doomed. According to the new statistics released by NASA the earth’s atmosphere’s CO2 levels has indeed passed the point of no return. Why is this so terrifying? Because CO2 is the one particular gas responsible for trapping heat inside the atmosphere (the whole global warming thing).
The recent studies has showed that the level of CO2 has passed the 400 parts per million unit which it’s a milestone since this hasn’t occurred in over 3 million years before the human kind evolved. This will directly result in some noticeable climate and sea level changes.
This is the famous Keeling curve showing the CO2 levels since the 1960’s.
350 ppm is the highest level that James Hansen says we can tolerate if we want to “preserve a planet similar to that on which civilization developed and to which life on Earth is adapted.”
“If humanity wishes to preserve a planet similar to that on which civilization developed and to which life on Earth is adapted, paleoclimate evidence and ongoing climate change suggest that CO2 will need to be reduced from its current 385 ppm to at most 350 ppm, but likely less than that….”
“Decreasing CO2 was the main cause of a cooling trend that began 50 million years ago, the planet being nearly ice-free until CO2 fell to 450 ± 100 ppm; barring prompt policy changes, that critical level will be passed, in the opposite direction, within decades.”
So what’s gonna happen?
If we reach the 450 ppm level, there will be a 3°C annual change in the earth’s atmospheric temperature. This will gradually lead into massive flooding due to the melting of the polar ices. Most southern Asian countries will be completely under water by then. After that will come the extreme heat part which will be a planetary extinction level.
What we can do now, is just hope that we can convince our governments and the entire world to focus on a real change in order to preserve the planet, so if we’re lucky enough there would be next generations of us living on this planet.
