Peter, you just stick with the standard and dwindling list of contrarians who’s opinions have gained zero traction in mainstream science. The data nor the plethora of empirical evidence supports their inane and stubborn stance that warming is “natural” Hint: It’s not the sun. It’s not orbital forcing. It’s not ocean currents. It’s not volcanism. There is no credible evidence whatsoever that current warming is natural. It is 100% human caused.
