Science 
My Back Yard
For a moment this morning I forgot about the climate cliff we are barreling towards and the bleak future that is just over the horizon if we continue on this dangerous path. Just for a moment today, I was oblivious, as so many of my friends, neighbors and colleagues continue to be. THIS HAS TO CHANGE.
Hiding our heads in the sand and ignoring the realities of climate change, won’t make it go away. It won’t stop the seas from rising, and it won’t stop the floods and droughts and other extreme weather that is our now and our future. But this doesn’t mean we can’t and shouldn’t “smell the roses” and enjoy the beauty around us, including the beauty of our children and grandchildren, in fact if we don’t remember these things, we will lose sight of why we need to take action.
We are crossing an interesting and telling threshold this year. The CO2 concentration in our atmosphere is reaching and will surpass 400

1. Going back 800,000 years the level of CO2 in the atmosphere stayed within a band between180 and 280ppm.
2. Since the industrial revolution (mid 1800’s) the level of CO2 has risen over 40% and over the past 20 years this annual rise has been accelerating at a faster and faster rate.
3. According to an article in the May 10th, New York Times, the last time C02 levels reached this high was over 3 million years ago, dinosaurs ruled the earth and sea levels were 60-100 feet higher then today.
“What we see today is 100 percent due to human activity,” said Pieter Tans, a National Oceanic and Atmospheric Administration senior scientist. The burning of fossil fuels, such as coal, oil and gas, are the overwhelming cause of human generated carbon in the atmosphere.
I have personally visited the Mauna Loa observatory on the Big Island of Hawaii – twice in the last five years. I have been privileged to talk at length to scientists that work there about the daily record of CO2 levels that has been recorded at their observatory since the 1950s.
When I was last at the Mauna Loa Observatory, on December 29th, 2011, the C02 
level was 392.14ppm. I was recorded on the side of the small vile of “air” I was given as a keepsake and have on my desk today. (You may notice the vile in my hand in this photo at the top of the graph). While at the same time that mother earth was sharing her wonders with me today, my heart grew a little sadder, as the weight of the climate crisis felt a whole lot heavier….
On the plus side (’cause I believe there ALWAYS is one) WE CAN do something about this and NOT accept rising levels of greenhouse gases as inevitable. We CAN fight back. We CAN stop burning fossil fuels, become more energy efficient and demand that we move towards and have access to an economy transformed by and with renewable energy. We need to talk about this serious and dangerous milestone with our kids, families and friends and we MUST create climate adaptation and mitigation plans at the family, community, regional and national levels.
It’s DO SOMETHING WEDNESDAY here at ClimateMama. So talk about this post with the kids in your life and DO SOMETHING as a family that will help us move way from the climate cliff and towards a sustainable, liveable future!
Yours,
Climate Mama
