No we don’t know all the factors but we also don’t necessarily need to. To make an example I don’t know all the factors behind lung cancer but I know if I continue smoking I will probably get it.

The same way if we release an abundance of CO2 along with other gasses into the environment (greenhouse gases that create our atmosphere and make the temperature milder) then with high probability that will have an influence on our climate.

Now let me just play this little game of yours:

1) a list of observations, which if observed, mean a hypothesis is false;

If the glaciers if the world were to start growing or at least cease melting then that would be one observations.

If the ice sheets in Greenland stop melting would be another.

If the land ice in Antarctica were to stop melting and falling of into the sea. I refer to the land ice because I have heard about the tricks that climate change deniers play when presenting satellite imagery of spreading sea ice sheets. From satellite imagery both sea and land ice look the same but the land ice is 1km thick and the sea ice 1m thick. Fact is The Antarctica ice sheet is melting. If the land ice were somehow replenishing itself that would be an observation to the contrary.

If the expanding of deserts such as the Sahara and Namib were to come to a halt or even regress then it would one more observation.

I just mentioned these when in reality there are many more examples I could give but believe for the time these will suffice (the others might come up later on).

Now comes step 2

2) tell me why those if the things that would change your mind aren’t there, the only explanation left is AGW.

First of all the phenomenon is global and is influencing the most different regions of the world. The global temperature has been rising since 1911. The probability of all these events being coincidental is next to impossible they are too similar and are happening simultaneously.

It could be due to the sun but the sun radiative output has not increased for the last 40 years even though the temperature has.

It could be changes in the earth’s axis or its orbit but such changes take tens of thousands of years not 100–40 years.

So since we’ve eliminated the radiative output of the sun, the earth’s orbit, its axis that leaves us with the atmosphere. Greenhouse gases have increased in the last 100 years. Greenhouse gases are responsible for the mild temperature we have indeed without the earth would be a calculated 33° C colder which brings the question what would happen if they were to increase?

Thus far we have come to the conclusion that the climate is changing due to green house gasses in the atmosphere.

The question now is: is it man made?

Well why are the greenhouse gases suddenly increasing in the atmosphere? The answer would be due to deforestation and the burning of fossil fuels since both release large amounts of CO2. There is no other logical answer to it. If it were natural then the rise in temperature would more gradual and part of an ongoing trend. The sudden rise in temperature is neither.

I know that the idea of anthropogenic climate change goes against your political beliefs and narratives but that does make the facts any less true and it doesn’t make climate change any less real.
