Climate alarmists point to:
increasing ocean heat content,
ice sheet mass loss, and
declining Arctic sea ice extent.
They completely forget, or never knew: All of those "indicators" of global warming have been in progress for the past 20,000 years.
That means natural causes of climate change are responsible for almost all of those years (the first 19,900 years, of the past 20,000 years) ... NOT man made CO2 emissions.
The so called "indicators" of man made global warming are the same indicators of warming from natural causes.
Climate alarmists would have us believe natural causes of climate change suddenly stopped after 4.5 billion years, and at some point in the 20th century, man made CO2 took over as the "climate controller".
And all natural causes of climate change were suddenly just "noise", as the IPCC declared in 1995?
The effect of human activities on climate change are assumed, and repeatedly asserted -- that is junk science.
The only real science is lab experiments that demonstrate CO2 is a minor greenhouse gas, that ought to hinder Earth's ability to cool itself -- mild, harmless global warming.
Since the mid-1970s, we have had mild harmless global warming.
