Scientists, with the exception of NASA (National Aeronautics and Space Administration) ’s Hansen, are preposterously cowed by big oil. They are like a fireman at a fire at the Zambelli fireworks plant refusing to speculate on the cause of the fire.
Fourier and Arrhenius worked out back in the 1800s how much the earth would heat up given various amounts of CO₂ in the atmosphere. We can measure how much CO₂ there is. We know how much fossil fuels we have burned so we can calculate how much CO₂ we humans released. We can measure the average temperature increase. All is coming true just as predicted.
We know that heat is energy and adding heat to the atmosphere will cause more energetic weather, bigger storms, bigger floods, dryer droughts, bigger wildfires, receding glaciers, plants, animals and birds showing up at higher and higher latitudes than normal. This is exactly what we are seeing. Yet still scientists have not the balls to tell the yahoo Australians who imagine they understand science claiming there is no problem to go find another planet to ruin. You cannot wait until the earth is literally on fire to act. By then it will be way way too late do anything.~ Roedy (1948-02-04 age:69)
