Taking the trend of warmer temps and colder winters for only the last 20-50 years and claiming that constitutes “climate change” is not statistically viable. Saying that humans are the cause of it is not backed by empirical evidence. Was the Ice Age on account of human activity? Are tropic zones hot because of human activity? The main problem of human activity has been pollution via plastics. Single-use plastics are choking the environment. Clean that up, plant trees, switch to organic farming as recommended by WHO, and this world’s environment will begin to right itself. No drastic and draconian measures that are going to, literally, cause the death of millions are necessary.
From my long list of climate prediction failures. GLOBAL WARMING TO WIPE NATIONS “OFF THE FACE OF THE EARTH” IF CLIMATE CHANGE NOT ADDRESSED BY YEAR 2000In 1989, the Associated Press relayed a warning from a U.N. official:“A senior U.N. environmental official says entire nations could be wiped off the face of the Earth by rising sea levels if the global warming trend is not reversed by the year 2000.”The official was Noel Brown, director of the New York office of the U.N. Environment Program, who added: "Shifting climate patterns would bring back 1930s Dust Bowl conditions to Canadian and U.S. wheatlands.”Instead, U.S. and global farm production rose, and more than 1 billion people worldwide rose out of extreme poverty due to economic growth.No nations were “wiped off the face of the Earth” as of 2019.However, those worried about warming caution that the U.N. official’s prediction was nuanced.“He is not saying that entire nations are going to be wiped off the face of the earth by the year 2000,” Joe Romm, a senior fellow at American Progress, told Fox News.“He is saying that if we don’t dramatically reverse emissions by the year 2000 — then we are not going to be able to avoid future flooding,” Romm said.“It now seems inevitable that a number of island nations will be wiped off the face of the earth because we didn’t act in time,” he added.According to NASA, global sea levels rose 3.5 inches in the 25 years since 1993, when it began reporting satellite data on sea levels.
The world’s lowest-lying country is the Maldives, a collection of Pacific islands with a population of just over 400,000, where the highest point in the country is 7.9 feet above sea level, with much of it below 3 feet.
Another:MASS STARVATION BY 1975In 1967, a best-selling book came out called “Famine 1975! America’s Decision: Who Will Survive?”It predicted mass starvation around the developing world due to increasing population. “Today’s crisis can move in only one direction – toward catastrophe,” it warned.Some experts praised the book and ridiculed doubters.“All serious students of the plight of the underdeveloped nations agree that famine… is inevitable,” Cal Tech biology professor Peter Bonner wrote in a 1967 review of the book in the prestigious journal Science.The exact opposite of the book’s prediction happened. Famine deaths plunged dramatically as farming technology improved, communist countries began allowing private property again, and the globe became further connected.According to a dataset put together by Our World in Data, more people died of famine in the single decade prior to the book’s release than in all 52 years since it was published.Yet the book got widespread praise from experts. Ecologist Paul Ehrlich, now President of the Center for Conservation Biology at Stanford University, said in 1968 that the book “may be remembered as one of the most important books of our age.”
A few years ago, the deniers here were making much ado about how the temperature prediction in 1988 by the climate model used by James Hansen’s group was higher than the observed temperature.
See! They gloatingly exclaimed, climate models are wrong!
Well, a couple of years ago, those same models were re-run. But there was a change in the parameters.
By 1988, the depletion of ozone in the upper atmosphere due to human use of CFCs was well known, and bad things were expected to happen without our curbing the use of CFCs.
But in 1990, the Montreal Protocols were passed, and have been implemented. The result is that ozone levels are recovering because we have reduced the amount of CFCs introduced to the atmosphere. That’s a victory for science and humanity.
When the 1988 climate model was re-run with the revised data about the ozone levels, the predicted temperatures were spot on with the measured values.
There are some important points here.
First, it is clear that human pollution can change the global the atmosphere on a global scale. (Ozone depletion)
Second, that human intervention can bring temperatures down (Less ozone depletion meant less warming).
This completely destroys the argument that humans have no effect on something as big as the global average temperature.
The third point is that this shows that climate science is not the made up stuff the deniers claim it is. Real physics and real chemistry go into the models.
It also shows that a model is only as good as the inputs to it. Climate models are not perfect, and work to improve them continues.
But as I pointed out above, if we left out the human greenhouse gas emissions, the models tell us that the global average temperature would have dropped very slightly since 1976. Instead, the global average is 1C higher than then.
And no, the temperatures do not follow the slight up and down of solar output. They are relentlessly increasing now because of the increase in greenhouse gases.

We could feed the lying troll who refuses to acknowledge reality.
-OR-
We could choose not to reply to people like @sojourner, whose willful ignorance has reached such harmful levels.
