Last week NASA and NOAA announced that 2014 topped the list of hottest years ever recorded. Yikes! What's worse, the ten warmest years ever recorded have all occurred since 1998. Yikes again!
In the meantime, the ACT is skiing on stones and rocks in Switzerland ^^
Did we just solve overpopulation and climate change?
With 40% more efficient crops we could easily sustain 10+ billion people on Earth.
And 40% more efficient plants would absorb much more CO2 than we are emitting (currently: artificial CO2 emission ~29 GT/y, photosynthesis CO2 capture through plants ~450 GT/y)
I am usually very worried about the risks of climate change, but this could be a real game changer!
A NASA study which is concerned with the question whether we could detect lost industrial civilizations on earth by analyzing the climate fingerprints.
once more ... the Romans did it already 2000 years ago! this time: burning so much wood that they increased the methane level in a way we can still measure it in ice cores ...
The loss rate of Mars' original atmosphere apparently has been quantified through isotope ratio measurements. Should be useful for climate engineering studies (Isabelle & Markus ?)
