Scary Headline: “Past Eight Years Have Been the Eight Warmest on Record”
Similar headlines have appeared in the “main-stream media” with the implication that the warming was caused by human emissions of carbon dioxide. In this case the “record” is from about 1979 to the present – ignoring the heat waves of the 1930s.
According to the Berkeley Earth global temperature database, surface temperatures have been rising since 1979 to reach a peak in 2016. However since 2016, temperatures have been cooling. There is no mention of that in the alarm stories.
According to meteorologist Anthony Watts, the 2016 peak in global temperature was caused by an extreme El Nino event in the Pacific ocean, a natural event which warms the planet which and has been going on for thousands of years. (Source)
Another view is gained from satellite measurements of the lower troposphere temperatures as reported by Dr. Roy Spencer.
Dr. Spencer notes that “Continuing La Nina conditions in the Pacific Ocean have helped to reduce global-average temperatures for the last two years.” “The linear warming trend since January, 1979 continues at +0.13 C/decade (+0.12 C/decade over the global-averaged oceans, and +0.18 C/decade over global-averaged land).” (Source)
Notice that a previous high-temperature point occurred in 1998 during a previous El Nino.
Some climate background:
Geologic evidence shows that Earth’s climate has been in a constant state of flux for more than 4 billion years. Nothing we do can stop that. Much of current climate and energy policy is based upon the erroneous assumption that anthropogenic carbon dioxide emissions, which make up just 0.1% of total greenhouse gases, are responsible for “dangerous” global warming/climate change. There is no physical evidence to support that assumption. Man-made carbon dioxide emissions have no significant effect on global temperature/climate. In fact, when there is an apparent correlation between temperature and carbon dioxide, the level of carbon dioxide in the atmosphere has been shown to follow, not lead, changes in Earth’s temperature. All efforts to reduce emissions are futile with regard to climate change, but such efforts will impose massive economic harm to Western Nations. The “climate crisis” is a scam. U.N officials have admitted that their climate policy is about money and power and destroying capitalism, not about climate. By the way, like all planetary bodies, the earth loses heat through infrared radiation. Greenhouse gases interfere with (block) some of this heat loss. Greenhouse gases don’t warm the Earth, they slow the cooling. If there were no greenhouse gases, we would have freezing temperatures every night.
