Earth ours

“Earth Hour was first unveiled by an Australian ad agency in 2007, when global atmospheric concentrations of carbon dioxide had reached 385 parts per million, their highest level in some four million years. Since then, CO2 levels have broken through the symbolic 400ppm barrier and continue to rise sharply.
The impact has been stark. Eight of the 10 hottest years ever recorded have all occurred since 2007. Last year smashed all previous records, pushing Earth systems into what the World Meteorological Organisation this week called ‘truly uncharted territory’.
If homo sapiens really has the wit and ambition to survive this century, from here on every hour has to be Earth Hour.” https://www.irishtimes.com/news/environment/lights-out-at-earth-hour-don-t-waste-your-energy-1.3022129

Blogging on battery power seems a decent analogy for stealing resources from our future selves.

Mental Methane

“Emissions of the powerful greenhouse gas methane have surged in the past decade, threatening to thwart global attempts to combat climate change. Scientists have been surprised by the surge, which began just over 10 years ago in 2007 and then was boosted even further in 2014 and 2015.” https://www.theguardian.com/environment/2016/dec/12/rapid-rise-methane-emissions-10-years-surprises-scientists

At these concentrations, time, or our perception of time, also increases by about 10%.

Expiring

“For the first time since records began, the parts per million (ppm) of CO2 in the atmosphere were over 400 globally. … The last time the Earth had this much carbon dioxide in the atmosphere was more than a million years ago, when modern humans hadn’t even evolved yet.” (http://www.theguardian.com/environment/2015/may/06/global-carbon-dioxide-levels-break-400ppm-milestone)

It’s not clear that modern humans have evolved even now.
