We routinely see misrepresentations of global warming. Few commentators seem interested in sharing the facts. It appears discussion regarding global warming are extreme with highly polarized claims. So let offer a very brief summary about what is real.
Global Warming is Caused by Humans: That is a lie!
The planet has been heating up and freezing for millennia, long before any human was present. Most recently we have the warm period around 1000 AD and the little ice age around 1800. The planet is currently warming up after the little ice age.
However, in the late twentieth century the warming seems to have accelerated. Nearly all scientists agree that humans are responsible for this change through the increased additions of greenhouse gases into the atmosphere.
Global Warming is a hoax: That is a lie!
Same comment as above.
Virtually all scientists agree that the planet is warming and increases in greenhouse gases are the major factor. This is the case where the science is not disputed.
The Paris Accord can halt Global Warming: Not Likely
Nothing in the Paris accord will reduce the continued increase is human produced greenhouse gases. India and China are expected to continue increasing their output of significant greenhouse gases, more than equal to the rest of the world combined.
The posturing by various world governments is mostly for show, including the US's withdrawal.
Climate Models provide a good idea of future warming: That is a lie
The climate models which have been the basis of much of the global warming hysteria are hugely wrong. In the last two decades, they have forecasted a 2 to 3 times greater temperature anomaly than actually occurred.
There was an 18 year hiatus in temperature increase that the models totally missed and still have not explained. The only thing we feel reasonably assured is that the temperature of the planet is increasing, but no where near at the rate the alarmist predicted.
Sea levels are rising: That is true
Warmer water occupies greater volume. The seas have been rising at a constant rate since measurements began before the industrial age. There has been no accelerated rate of increase in recent years.
Polar bears are in danger of extinction: No one knows
In the last twenty-five years the numbers of polar bears have been increasing.
Weather extremes are getting worse: Not true
The numbers of tornadoes and hurricanes have been decreasing.
