Folks,
I left the below comment in response to this video. It was too good to leave it forgotten in a YouTube comment, so I copied and pasted it below for posterity. The presenter mentioned climate change as a reason to promote cycling in cities. While I'm an avid cyclist (I own five bikes!); while I try to use my bike for more than just fun (I run short errands on it); I don't want my car taken away, either. Also, I question just how big a role humans play in climate change, as I think there are sinister, ulterior motives for it, questions which I raise in the comment below.
Before I forget, MERRY CHRISTMAS, everyone! I wish you nothing but health and happiness on this Christmas Eve of 2024.

My second comment concerns climate change. I don't know of man is playing much, if any, role in climate change. One, CO2 is a trace gas in the atmosphere; it comprises 0.033% of Earth's atmosphere. I'll provide sourcing at the end. Two, CO2 is necessary for life; CO2 is to plants what O2 is to us: the breath of life. Via the process of photosynthesis, plants "inhale" CO2, and they "exhale" O2. Plants need CO2, while we need O2. To put it another way, more CO2 means more plant life, which ultimately means more O2 for us. Thirdly, methane (hereafter referred to as CH4), comprises an even smaller portion of the Earth's atmosphere, as it is measured in PPM. To learn more about CO2 and CH4 composition in the Earth's atmosphere, go to the linked, official US Government document (an FAA advisory circular), and consult the table on page 17, which is found here: https://www.faa.gov/documentlibrary/media/advisory_circular/ac_00-6b.pdf
Five, if human driven climate change were REALLY a thing, then WHY, pray tell, are India and China, basically exempt from the Paris Climate Accords? Why are they permitted to build all the dirty coal power plants they want, while Western nations are forbidden from doing so? Why are Western nations forbidden from building any fossil fuel power plants, including clean natural gas, at all? If climate change were really the problem that we're told that it is, shouldn't all nations be playing their part to reduce emissions? After all, thanks to high altitude winds, won't these emissions be spread worldwide? Won't they ultimately affect the whole world? Hence, shouldn't China and India, two of the worlds biggest polluters, also be subject to the Paris Climate Accords? To ask those questions is to answer them.
Six, many of those promoting human climate change don't believe it. Our former President, Barack Obama, constantly preached warnings about climate change and how it would cause sea levels to rise. Even so, he and his wife purchased a $15,000,000 mansion ON THE BEACH! If rising sea levels were going to be a problem anytime soon, then why spend that kind of money on an expensive property that will soon be submerged? Wouldn't that be a huge, irresponsible waste of money? In other words, if the Obamas REALLY believed in climate change and rising sea levels, wouldn't they buy a place on higher ground? Again, to ask the question is to answer it.
Seven, another factor of climate change (I dare say the major one) that's ignored are natural factors. I'm talking about volcanoes, undersea volcanoes, and sunspots. It's no secret that erupting volcanoes spew THOUSANDS of tons of debris and gas into the atmosphere! Anyone remember Mt. St. Helens? Anyone remember Mt. Pinatubo? Or how about the 1815 eruption of Mt. Tambora, which gave us the year with no summer, 1816? Can you say that volcanoes have no effect on climate? What about undersea volcanoes? They heat up the ocean, and the ocean is a major driver of Earth's weather. The well known weather phenomena of El Nino and La Nina are both tied to ocean temperatures, and both El Nino and La Nina have a huge impact on our weather. High ocean temperatures are also the energy and driver of hurricanes.What can we do about undersea volcanoes? NOTHING! There are also sunspots to consider. The number of sunspots has been correlated with the sun's temperature. ICYMI, the sun is the major driver of Earth's weather and climate, and indeed is responsible for life on the planet. What can we do about sunspots? Again, nothing. With the sizable impacts these natural forces and phenomena have on Earth's weather and climate, WHY are they never considered, let alone studied, when it comes to the subject of climate change? Why?
Eight, when one digs a bit on the man made climate change issue, WHY are the same solutions always proposed? Why is it, if we just pay higher taxes (or indulgences, if you please), we'll be fine?
Nine, when it comes to climate change, we're told to shut up; we're told that the science is settled. Uh, true science is NEVER settled! True science entails study, discussion, hypotheses, theories, and testing of the same; true science invites examination. In fact, it's only when "settled" science is challenged that true advancement takes place. Look at how Galileo challenged the Earth centric theory of the universe back in the 17th Century; thanks to his questioning of the "settled science" of his time, we were able to adopt the correct heliocentric model of the universe, and scientific knowledge advanced.
Ten, did you know that there was a warm period in England during Medieval times? Did you know that, during this time period, that VINEYARDS were in England? Did you know that this Medieval Warm Period occurred from 900-1300, AD? How could this be, though? Wasn't this literally CENTURIES BEFORE the Industrial Revolution? Wasn't this centuries before Man developed mechanized means of production and transportation? Therefore, wouldn't that mean that Man could not have been responsible for the Medieval Warm Period? Did anyone ever think about that?
Finally, the very first step of the scientific method is to define the problem. What is it? What is it not? How does this problem manifest itself? Under what circumstances does the problem manifest itself? And so on. That is to say that defining the problem is the crucial, foundational step; if the problem isn't correctly defined and understood, then any subsequent solution will be wrong.
