It isn’t uncommon for climate skeptics to claim climate predictions have been wrong. Many climate change predictions are based on modeling, which involves putting data into a computer program and having the program make predictions. It’s not a perfect science, as it’s difficult to account for all the relevant data about an entire planet.
One way to determine a model’s accuracy is to look at old models and see how well they withstood the test of time. A 2019 study in the journal Geophysical Research Letters showed that of 17 climate models published from 1970 to 2007, 10 closely matched the global average temperatures that occurred. That number increased to 14 after "accounting for differences between modeled and actual changes in atmospheric carbon dioxide and other factors that drive climate," according to a 2020 NASA article about the study.
Another 2012 study in the journal Nature Climate Change found that 1990 predictions from the Intergovernmental Panel on Climate Change were fairly accurate. IPCC had suggested that by 2030, Earth would have warmed about 1.1 degrees Celsius, which would amount to about 0.55 degrees Celsius by 2012. The warming that occurred was about 0.39 degrees Celsius.
Despite the difference in the projected and actual temperatures, the 1990 prediction is accurate, Penny Whetton, senior principal research scientist at the Australian government agency Commonwealth Scientific and Industrial Research Organisation and a lead author for the Third Assessment Report of the IPCC, told the nonprofit news website The Conversation in 2012. The difference between the projected 0.55 degrees and the observed 0.39 degrees is because of natural fluctuations, Whetton said.
"This is good evidence to show that what the IPCC has been saying for a while is coming true," she added.
People have been saying silly things and getting predictions wrong for as long as they have been talking. But to do it deliberately, as you do, is fortunately much rarer — unenlightened

I have been banging on for ages about sea level rise as a major factor that will affect us — unenlightened
Sea levels have been slowly rising since the end of the Little Ice Age around 1850. Coastal cities have not disappeared though, because in the normal course of constantly rebuilding structures and infrastructures, we have been elevating them. For the most part, this is not a piece of some grand master plan (other than building codes for new structures), but the basic fact is that “new” cities are constantly being built on top of “old cities,” a practice that has gone on for at least a few thousand years. — The Global Warming Apocalypses That Didn’t Happen

why do you consistently call others alarmists and scaremongers? — jorndoe

What I find hilarious is that it’s not just “alarmist,” which we’d all understand— he has to, each time, type out “climate change/global warming alarmist.” — Mikie
Using data from researchers at the University of Maryland, recently updated to cover the years 2001 to 2023, we calculated that the area burned by forest fires increased by about 5.4% per year over that time period. Forest fires now result in nearly 6 million more hectares of tree cover loss per year than they did in 2001 — an area roughly the size of Croatia.
