400.
For the first time in human history, carbon dioxide levels reached an average daily level of 400 parts per million, as reported this week. The last time the atmosphere contained this much carbon dioxide was 3 million years ago.
This new data comes from the Mauna Loa observatory and a set of data continuously collected since 1958: The Keeling curve. This represents almost a 50% increase since the beginning of the industrial age. Although there is some seasonal variability (that little jagged edge) due to seasonal vegetation sucking up a bit of the CO2 every year, the trend is clear … and it’s not good.
So what does that mean? The effects are not something to look forward to. The last time the CO2 level was this high, way back when, here’s what the world was like:
Back then, it was a different world. Global average temperatures during the period were between 5.4 and 7.2 degrees Fahrenheit (3 to 4 degrees Celsius) higher than today, and sea level was as much as 131 feet (40 meters) higher in some places.
While the average (which is calculated from levels over the past several days) has since dropped back to 399 (as of today), the saddest part is that both of those numbers are unacceptable. 400 is just a little more catchy. With 401 and beyond right around the corner, what now? We must cut emissions as fast as humanly possible.
Because we are mighty humans, and it is possible.
We need to take care, because we all share this air. Read about the science of our CO2 contribution here. Watch this episode of It’s Okay To Be Smart to gain some hope maybe.
What do you think is the #1 thing we can do to change? What are YOU willing to do?
“The Lord is my shepherd, I lack nothing.
He makes me lie down in green pastures,
he leads me beside quiet waters,
he refreshes my soul.
He guides me along the right paths
for his name’s sake.
Even though I walk
through the darkest valley,[a]
I will fear no evil,
for you are with me;
your rod and your staff,
they comfort me.
You prepare a table before me
in the presence of my enemies.
You anoint my head with oil;
my cup overflows.
Surely your goodness and love will follow me
all the days of my life,
and I will dwell in the house of the Lord
forever.”
Selah.
