I was in a class at a local college in1974 when it was predicted the next global cooling and ice age were upon us ,wood hole ,scrips ,NASA were contributes to the class .it was assured by there data,the class was oceanus.check it out.also when scientist falsified date to prove there hypothesis none of the data can be trusted.when politicians are making massive amounts of money there theory's can't be trusted. When historical data (complete changes in an area climate , forest,swamps ,deserts)over thousands of years is dismissed as not relevant
