Recently, two science articles based on the latest research belies the notion, held by global warming alarmist proponents, that climate change is only a result of modern human CO2 emissions.
As skeptics of catastrophic global warming have long advised, climate change is primarily a result of natural forces that are not dependent on anthropogenic influences.
An example of this earthly natural climate change is the Little Ice Age (LIA), which had serious repercussions for many, including the Mongol invaders who terrorized Europe.
Researchers now believe that the underlying cause of the mysterious retreat by the Mongol invading forces of Hungary, during 1462 AD, was the bad weather - likely induced by the natural climate change associated with the LIA onset. Turns out the bad weather of climate change significantly reduced food and nutrition for the Horde's steeds and made for a very muddy terrain to battle on.
And then there is the new research from another planet in the solar system that proves natural climate change is not only a terrestrial phenomenon.
Research derived from the Mars Reconnaissance Orbiter has established that the Mars ice age is in the process of ending due to a natural global warming for that planet.
In combination, these two research efforts add to the massive amount of scientific evidence that climate change is always occurring; and, most definitely does not require human consumer/industrial greenhouse gases to produce significant impacts on planetary environments and those associated civilizations.
