Climate change is very important; the biggest problem we face today. Here's a cut-n-paste of something I wrote earlier:
[quote]but I've yet to hear a rational explanation of how miniscule increases in an atmospheric trace gas such as CO2, causes the earth to warm.[/quote] It's because CO2 & methane are transparent to visible light but more opaque to infrared. The solar energy comes pouring in via the visible spectrum, but the heat can't leave so easily via the infrared spectrum due to that opacity. Kids' version:

[quote] In order to actually prove human carbon emissions influence climate, all variables would have to remain constant[/quote] Nope. With multiple data points we can solve for multiple variables simultaneously. Detailed climate models account for all the variables you list and more. They are verified and calibrated based on 700,000 years of prior climate data.

Nope, not 50 years, 700,000 years, covering about 7 ice ages. The climate data comes from bubbles in glacial ice, and is corroborated by data from sea floor sediments.

Here's [i]where[/i] the various data sets were collected:

The most salient thing about the 700,000 years of climate data is the rate of change during those previous 7 ice ages compared to the current rate of change this century.

[quote] Where does the money for climate research come from?[/quote]
Fair question. Equally fair: where does the money for climate denial come from? The US oil industry makes about $110 [i]billion[/i] per year; coal another $20 billion. Big Oil spends $3.6 billion per year on advertising; a sum equal to about 8X the whole NSF climate budget. You're not naive enough to believe [i]none[/i] of that money goes to propaganda, are you?

@Budwick The global warming / climate change we're seeing in the last 100 or so years is MUCH different from anything measured in the glacial & sea sediment records covering the last 700,000 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/

Yes, its a sign of the end times, and that we have to get our act together. Don't throw trash, ride your bike, and love Jesus because Jesus is coming soon. Here is a Bible verse about taking care of the earth
[quote]"And the nations were angry, and thy wrath is come, and the time of the dead, that they should be judged, and that thou shouldest give reward unto thy servants the prophets, and to the saints, and them that fear thy name, small and great; and [b]shouldest destroy them which destroy the earth[/b]. Rev 11:18"[/quote]
