From the late 70’s until today, the birth of new technology has ushered in a more reliable way of measuring the global temperature and other climate info. This comes from the birth of Satellites. I tend to stick to watching the satellite data as it hasn’t been subjected to the unreliable and tampered with weather station data.
Before you go off on accusing me of being a conspiracy theorist on the tampering of data. All climate measuring organisations adjust the data records for various reasons
Prior to 1979 data was collected at increasing numbers of measuring stations around the globe. From 1880 thermometer measured global temperature records start. The first reliable thermometer was invented in 1714.
The accuracy of calling measurements truly global data prior to around the 30’s is a little bit of a stretch. The video below shows the growth of global weather stations over time.
in 1880 you will see that there is a few incomplete year data measurements in east and western USA and a few stations in the middle, Europe is pretty well covered, the east coast of Australia has a few and so does southern India
Missing from this data collection is North America (north of the USA), all of South America, All of Africa, the middle east and the Russia and Asian areas. The weather stations cover about 5% of the globe at best.
It isn’t really until about the 1930’s that you have a pretty good spread around the glob,e and 1960 that you can say there is a wide spread of weather stations. Including a few spread around the oceans.
When we look at the weather data we see the following graph
If you look at the graph you see warming. However the far right hand side of the graph is registering about 0.5 of a degree Celsius. However what this graph is showing is a warming and cooling that can only be called natural variation.
This graph might put things in perspective in relation to warming and CO2
If the rise in CO2 was directly linked to warming you would expect to see a warming more consistent with the rise in CO2.
There are plenty of graphs that show constant large amounts of warming however the graphs above are downloaded directly from the Satellite data. You can download it yourself from below

So back to the satellite data graph. the reality is if CO2 was increasing and had a direct impact on the warming, it would be unlikely that we would go through periods of cooling.
However, if you look at this graph from a warming and cooling perspective you will see that there has been cooling periods as well as warming.
We have experienced 15 cooling periods over the period of increasing CO2 since 1979. CO2 has relentlessly risen in this time. below is the data on atmospheric CO2
Even the lock downs and drop in flights has not managed to effect the rise in CO2. However, the data shows a warming and cooling over the past 40 years.
The graph below is the graph we are used to seeing
What you will notice from the graph above is that the period of where the earth had about 5% of the mass measured by weather stations the data is sitting much lower than now and that we see this sudden growth periods from 1920’s to the mid 40’s. a gradual drop to the 80’s and then a steep climb ever since.
One thing to note is that there is quite a large gap between 0 and 1 degree which makes the graph quite steep. this is a common trick and i decided to use this trick in reverse showing how little change there has been with this graph from the data I downloaded.
The above graph makes the temperature changes look absolutely inconsequential, which it realistically is.
The reality is temperature changes are so insignificant that unless someone mentioned it, no one would notice any change.
The next thing we are warned of is sea level. Luckily this has been more accurately measured over the years. The good news is that we are seeing a typical linear rise and no extreme changes. check out the graph below.
Once again no change in the level based on CO2 content of the atmosphere.
We are told that we are experiencing increases in wild and crazy weather events that are putting peoples lives at risk.
here is the actual reality
Storm frequency and intensity is meant to be getting worse and we are seeing more and more dangerous Hurricanes etc. well lets look at this measured once again by satellites
Once again the data shows no trend going upward.
below is a telling one in terms of danger to life
Then there is all those droughts
Yet our politicians are declaring climate emergencies like there is data that shows we are in trouble.
