If people don’t have an understanding of what science is, and what scientists do
…then they can tend to think that global warming, for example, is just a matter of opinion.

@AuRevoir says
Let's start with the facts about scientific cooling vs warming predictions. Cooling predictions were NEVER a major thing; propagandists blew them out of proportion. Look at the facts:

The change in terminology from "global warming" to "climate change" was done because there are many ramifications to warming that are more significant than mere temperature. The most serious is sea level rise.
Sea level rise, mm/year, as measured by GPS
Sea levels have risen 6 to 8 inches in the past 100 years. But the process continues even after the warming stops.
8000 years of sea levels
Sea levels have been quite stable for the last 2000 years while humans built coastal cities. Climate change now threatens to raise sea levels and swamp those cities.

It’s already been disproven to the point that they went from ice age scare tactic, to global warming scare tactic, and now it’s no longer specifically about warming, it’s simultaneously supposed to be about both warming and freezing so now it’s Climate Change.
It's SCARY how wrong you are, and how much propaganda you've internalized.Let's start with the facts about scientific cooling vs warming predictions. Cooling predictions were NEVER a major thing; propagandists blew them out of proportion. Look at the facts:

Sea levels have risen 6 to 8 inches in the past 100 years. But the process continues even after the warming stops.
Between about 21,000 years and about 11,700 years ago, Earth warmed about 4 degrees C (7.2 degrees F), and the oceans rose (with a slight lag after the onset of warming) about 85 meters, or about 280 feet. However, sea levels continued to rise another 45 meters (about 150 feet) after the warming ended, to a total of 130 meters (from its initial level, before warming began), or about 430 feet, reaching its modern level about 3,000 years ago.
This means that, even after temperatures reached their maximum and leveled off, the ice sheets continued to melt for another 8,000 years until they reached an equilibrium with temperatures.
Stated another way, the ice sheets’ response to warming continued for 8,000 years after warming had already ended, with the meltwater contribution to global sea levels totaling 45 additional meters of sea-level rise.
From about 3,000 years ago to about 100 years ago, sea levels naturally rose and declined slightly, with little change in the overall trend. Over the past 100 years, global temperatures have risen about 1 degree C (1.8 degrees F), with sea level response to that warming totaling about 160 to 210 mm (with about half of that amount occurring since 1993), or about 6 to 8 inches. And the current rate of sea-level rise is unprecedented over the past several millennia.

@ElwoodBlues climate change is a natural occurrence. Hence the ice age.

@specman True, climate does change naturally. But the RATES of change we're seeing now are MUCH different from anything measured in the glacial & sea sediment records covering the last 800,000 years. CO2 is rising 100x faster, and temps 10x faster.
"How is Today’s Warming Different from the Past?" https://earthobservatory.nasa.gov/features/GlobalWarming/page3.php "As the Earth moved out of ice ages over the past million years, the global temperature rose a total of 4 to 7 degrees Celsius over about 5,000 years. In the past century alone, the temperature has climbed 0.7 degrees Celsius, roughly ten times faster than the average rate of ice-age-recovery warming."
How is today's CO2 increase different? https://www.climate.gov/news-features/understanding-climate/climate-change-atmospheric-carbon-dioxide "The annual rate of increase in atmospheric carbon dioxide over the past 60 years is about 100 times faster than previous natural increases, such as those that occurred at the end of the last ice age 11,000-17,000 years ago."
Fact is, anthropogenic global warming is accepted by a YUGE segment of the scientific community. Would you accept the consensus opinion of the American Physical Society AND the American Chemical Society? How about the American Association for the Advancement of Science, and at least 15 other national organizations of publishing scientists? See https://climate.nasa.gov/scientific-consensus/

@ElwoodBlues I don’t know if you are a Christian or not, but the Bible says a quickening will occur before the second coming of Christ.
@ElwoodBlues the apocalypse
ElwoodBlues · M
@specman I think I'm gonna need a more specific answer regarding causes vs "happens at the same time." Also, what's the biblical definition of 'quickening'?
UPDATE: I found this on the web:
The word quicken is used in the King James Version of the Bible, and it means “revive or make alive.”
Is that the same thing as a rapid increase in CO2?

@ElwoodBlues yes!
Just kidding!
I have no clue the Bible is mysterious and I’m definitely not a scholar. Just my brief opinion after reading the Bible numerous times in the past. I used to be very religious but doubt has entered the equation. I wish I could be more religious again life was so much easier.

@Therealsteve As I said above, the most serious aspect of our current anthropogenic climate change is sea level rise.
Rapid warming leads to rapid glacial melting leads to rapid sea level rise leads to more and more flooding of our low lying cities. See the bottom map of increased coastal flooding in the US. Walling our coastal cities off from extra feet of sea level is a very expensive proposition. An ounce of prevention is worth a pound of cure.

@ElwoodBlues There isn't anthropogenic climate change, though.

@Therealsteve What data led you to that conclusion??
You call 800,000 years of correlated temperatures with greenhouse gases a mere coincidence??
800,000 years of CO2 & methane & temp data
