Recent data indicates that the pace of C02 buildup in the atmosphere is moving faster than expected, raising speculation of the dreaded “feedback effect” kicking in. Computer simulations have predicted this, now it may be happening — or it may just be a temporary anomaly. In a few years we will know, once we have more data. If indeed feedback is taking place, predictions indicate that massive global warming effects will take place much sooner than expected. Time to invest in that houseboat you always wanted?
