Global Warming

Rather than label global warming fake, why not just read a short summary? It does not really help thinking science is a conspiracy. Sets of thermometers in various parts of the world are managed and reported by national or regional agencies. These numbers come from a permanent set of thermometers that give a number for each day at its location. As they are the same meters, the near term (20-30 years) numbers are as reliable as we can get. Some numbers are routinely corrected. This is not tampering. As each set is corrected the same way, the numbers obtained for temperature rise give a reliable trend. The method starts with an average temperature of 13.9°C (57.0°F) for the 1900s. The rise ("anomaly") reported is just added to that. On any day the planet has areas that are in summer and areas that are in winter. The average over the planet gives that 13.9°C. For example +0.94°C gives 14.8C.

 

NOAA/NCEI annual global analysis for 2017: 

The 2017 average global temperature across land and ocean surface areas was 0.84°C (1.51°F) above the 20th century average of 13.9°C (57.0°F), behind the record year 2016 (+0.94°C / +1.69°F) and 2015 (+0.90°C / +1.62°F; second warmest year on record) both influenced by a strong El Niño episode. The year 2017 is also the warmest year without an El Niño present in the tropical Pacific Ocean.

2017 also marks the 41st consecutive year (since 1977) with global land and ocean temperatures at least nominally above the 20th century average, with the six warmest years on record occurring since 2010. Since the start of the 21st century, the global temperature has been broken five times, three of those being set back to back (2014–2016). The yearly global land and ocean temperature has increased at an average rate of 0.07°C (0.13°F) per decade since 1880; however, the average rate of increase is twice as great since 1980. From 1900 to 1980 a new temperature record was set on average every 13.5 years; however, since 1981 it has increased to every 3 years.

Overall, the global annual temperature has increased at an average rate of 0.07°C (0.13°F) per decade since 1880 and at an average rate of 0.17°C (0.31°F) per decade since 1970."  [NOAA global analysis for 2017 accessed September 18, 2018].

A video demonstration of CO2 and IR light experiment. The tablets used release CO2 which dissolves in the water until it is saturated and after that some goes into the air above the liquid. This is a large amount of CO2 just to demonstrate the effect. It does have a control with no added CO2.

The water does play some part. Some people claimed all kinds of faults with the demo, but all it shows is IR absorption by the gas above the water.

Here is a more sophisticated video that simply shows the gas absorbing the light from the candle. The gas absorbs the IR light and re-emits it but it is not going to just the camera but in all directions. Air in the tube did not do that.

As far as conspiracies, there are always people willing to believe them. Especially if "government" did something to them. If you are curious how the theories form and spread, see this book, which is not a debunking book, but focuses on the mind.
