National Geographic has long lost any scientific credibility on climate change issues. It’s new project, “Seven things to know about climate change”, does nothing to restore it.
In fact, as their graph clearly shows, temperatures have been steadily rising the 19thC, long before CO2 emissions could have made any noticeable difference.
Why is there no mention that the Little Ice Age, culminating in the late 19thC, is known to be probably the coldest period in Earth’s history since the end of the last Ice Age?
They also mention satellite measurements, but strangely forget to state that atmospheric temperatures last year were no higher than in 1998.
Stand by for the “Second Thing We Should Know”!
