For the past 20 years global temperatures have not risen significantly. Neither have they fallen much; they have “plateaued.”
But based on the increase in CO2 levels, computer models said that temperatures should have kept rising. Climate change alarmists insist that they have kept rising, or at least stayed high enough to keep setting some records. And, they’re right. Several years in the past 20 have recorded temperatures near or slightly above the highest temperatures recorded in the last century. So what does it mean?
Here’s a picture of a plateau. As a verb, to plateau means reaching a state of little or no change following a period of activity or progress. As a noun, a plateau is an area of relatively level high ground.
You’ll notice that the sides slope up until they reach the top, and flatten out, or plateau. This level, high ground continues on for some distance, as a plateau, and then falls away again.
How does this relate to global warming? Well, as you should know, for the last 15,000 years we have been exiting a major Ice Age. During that exit, temperatures have generally gone up, but with some downs; glaciation has generally retreated, and, as the land ice has melted, sea levels have risen, by about 130 metres or 400 feet. It’s not an even climb.
1000 years ago, it was warmer than it is now, then for several centuries, it cooled off during what is known as the Little Ice Age. Glaciers advanced and overran towns in the Swiss and French Alps; the Thames River in London froze over completely – it last did that in 1814 – and crops in the northern United States froze in July. But since about 1850, we’ve been warming up again.
But even so, there have been ups and downs in temperature. The 1920s, 30s and 40s were hot – some of the records still stand – but then it cooled off, and in the 1950s 60s and 70s, many scientists were predicting a new Ice Age. I remember the alarm: “What are we going to do to fight GLOBAL COOLING?! “
At the end of the 70s it began to warm up again until about 1998 when it reached a plateau. We’ve been bouncing along the top of that plateau for nearly 20 years, with occasional annual records being set by 1/10 of 1°, a number which is totally meaningless except to people employed in writing newspaper headlines, or extracting research grants from taxpayers.
So here are a couple of things to think about. If CO2 levels have risen significantly for the past 20 years, and they have, why has the temperature plateaued? Could it be that CO2 is not that important a greenhouse gas? After all, water vapor makes up 95% of greenhouse gases.
The other thing generally agreed upon is that the increased CO2 levels have been responsible for a major increase in plant growth around the world. Even parts of the Sahara Desert are turning green, again. CO2 is as essential to plants as oxygen is to you.
But, in spite of this, you’ll regularly hear someone say: “We have to tackle climate change.” What does that even mean? It’s just more babble from the Progressivist Left meant to impress you with how virtuous they are; no connection to reality required.
The climate change industry is a racket. Some in it are getting rich, and some are getting famous, and a lot of people in the industry, who know better, just don’t have the guts to speak the truth. Those that do speak out usually lose their jobs. That’s not science.
Politicians like Justin Trudeau and Barack Obama and Kathleen Wynne and Rachel Notley and now the unholy alliance of the Greens and NDP in BC have no interest in science; they are interested only in implementing their left-wing ideology, and shutting down Canada’s energy industry business. Saudi and Venezuelan oil are apparently quite acceptable.
Canada’s environment Minister Catherine McKenna says that Canada is “Marching on” with the Paris Accord and 200 other countries. Yes they are, like a herd of lemmings. You might think Donald Trumps is nuts, but he’s not that nuts.
Climate change is normal, and the reason that we’re still here because our ancestors adapted to that reality. They even adapted to a 400 foot sea level rise, by moving to higher ground.
Do you notice that you don’t have to be a scientist to figure this out? There’s no excuse.
