Another good documentary on the climate change hoax.

It is a bit dated (2007), though, it contains plenty of relevant information for fighting back against the doomsday scenarios, which are conveniently available to push forward certain political agendas.
A summary of the many topics covered:
- the intolerance for dissent against their narratives (censorship, cancel culture)
- atmospheric CO2 levels lag behind temperature changes by ~800 years in the geological records, not vice versa. In other words, temperature changes drive CO2 changes, not the reverse
- the fake news surrounding climate change narratives, how the propaganda works
- the convergence of interests (money, ideology, political power, notoriety, etc.) which led to the rise of the overall climate change narrative
- how the narrative actually harms the developing world
- climate is most strongly controlled by changes in the Sun, not atmospheric CO2 levels (this plot from the documentary nicely illustrates that point: https://imgflip.com/i/51mcfi ). Changes in the Sun's luminosity result in changes of our (water) clouds, which then controls the surface temperature. This was apparently well understood and agreed upon by the climate science community just before the climate change narratives began to really gain traction
- greenhouse gas models imply a particular temperature structure of the atmosphere, the data (satellite & balloon measurements) directly contradict these models, in fact, the opposite occurs than what the models predicted
- humans output a small fraction of CO2 compared to the other sources of atmospheric CO2 (i.e., volcanism, the ocean, etc.)
- how the doomsday narrative used to be about a "great freeze", aka, a new ice age, which was abandoned for various reasons (political and science driven)
- the drift of climate change narratives to become more and more fearful
- models are only as good as the assumptions which go into them (i.e., the underlying physics, input parameters, etc.). One poor assumption and the prediction can be quite wrong. Consequently, a model can exist to make just about any prediction about the climate (temperature goes up, goes down, catastrophe, non-catastrophe, etc.)
- how sea level changes actually work
- the fantasizing of pre-industrial civilization (and third world countries) by "environmentalists", whom, ignore the poor living conditions of these times and places
- atmospheric CO2 is not a pollutant
- malaria is not a tropical disease (one of the largest outbreaks was actually in a cold region of Russia), so, global warming isn't going result in a huge increase in malaria deaths
They didn't use some of the words/language above, but in effect, this is what was meant.
Ice tends to melt faster when not in a PH neutral environment.
As ice melts, the colder water is drawn down because it is more dense than the surrounding water.
If the surrounding water is salty, however, then the colder water is not as dense as the salt water and actually insulates the ice. That means salt water can actually make ice melt SLOWER. It seems backwards, but it is true, so long as the cold water surrounding the ice isn't drawn away. Here's a video showing this: https://www.youtube.com/watch?v=EF0RlTCk_b4
If the salty water is acidic, however, it disrupts this process slightly and allows the ice to melt faster.
I just ran this experiment in my kitchen, and acidic water did increase the melting rate.
I had 3 glasses of water, all the same temperature. Two of the glasses I added a spoon of salt water and stirred them. In one of those I added two spoonfuls of vinegar.
I added an ice cube to each glass. The pure water glass melted the fastest. The one with vinegar next and then shortly the salt only, confirming my hypothesis that acid added to the salt water increases the melting rate. You can run the same experiment for yourself.
Oh great point. Did not think about how the density of the melting water would compare to the salt water.
I would be super curious to learn what the mechanism of the acid protection is.
