Take former U.S. President Barack Obama:

Our changing climate is already making it more difficult to produce food… We’ve already seen shrinking yields and rising food prices.

This is indeed what climate alarmists have been predicting for decades.

But 2016 in fact had record harvests, which have been steadily rising.

If Obama means only the harvest per hectare is shrinking, he’s again wrong.

From a CSIRO report:

World wheat, rice and soybean yields have been increasing linearly over the past 20 years.

And he’s wrong about food prices, certainly when measured in real terms:

So wrong, wrong and wrong. But which expert will denounce untruths told in such a noble (?) cause?

UPDATE

The CSIRO report does warn that yield growth may slow or even stop, but global warming has little or nothing to do with…
