We must reduce our emissions 100% by 2040 to stay under 2 C. But our emissions are projected to rise 16% by 2040. And our energy use is projected to rise 30% by 2040. Yet James Hansen says 2 C = Disaster. Kevin Anderson says we have a 5% chance of staying under 2 C. I believe we already have 0% chance of staying under 1.5 C. 2040 is 22 years away, yet world water demand will exceed world supply by 40% by 2030, in just 12 years. World electric grid production is only 20% of total world energy demand. It will several decades minimum to convert 100% of total world energy demand to renewable energy. Europe gets 50% of its renewable electricity by burning wood. James Hansen says that after 20 years of trying, solar and wind only make up 2% of total world energy demand. You keep hearing we can have 100% renewable energy by 2050. This is a lie. We will not have enough minerals, soil and water to do this. In 2010 copper ore grades were 30 lbs/ton of ore. In 2016 copper ore grades are 3 lbs/ton of ore. By 2025 copper ore grades will be under 2 lbs/ton of ore. No amount of money can change that. A wind turbine uses 100 times more copper per unit of energy than fossil fuels . An offshore wind turbine uses 1,000 times more copper per unit of energy than fossil fuels. They are also exposed to super storms. All the solar panels and wind turbines you see now will have to be replaced in 30 years, but it takes 70 years to change society over to 100% renewable energy. Renewable energy has to be replaced 2 times faster than it takes to convert the whole world over. We will always have essential minerals, but not at cheap enough prices. When ore grades go down and energy costs go up, society collapses. We are losing soil to degradation and erosion so fast that human agriculture is projected to end in 60 years. We have to grow more food between now and 2050, than in all of human history to feed people the way they eat now. To this we need 12 million acres of new soil per year for 30 years. But we are losing 24 million acres of soil per year to degradation and erosion. We are losing soil 2 times faster than we need to find new soil. Within 1-10 years the world economy will crash. Deep down you know all this to be true. https://www.reddit.com/r/collapse/comments/82e9cm/the_terrible_truth/ |
