Are you denying human caused climate change because you don't think there's enough data to support it? You believe the data supporting climate change theories only dates from 1979? Well, great news, I have lots of reading that will quickly get you up to date and help you understand that climate change isn't demonstrated only through satellite models! In the IPCC Sixth Assessment Report introduction, you can see the various methodologies used to demonstrate the effects of human-caused climate change: https://www.ipcc.ch/report/ar6/wg1/chapter/chapter-1/#1.3 https://www.ipcc.ch/report/ar6/wg1/chapter/chapter-1/#1.3 For example, we've been taking thermometer and barometer observations at Earth's surface since the 1600s. By the 1800s this was widely distributed through naval weather logs. For atmospheric readings, we've been getting those since the 40's, not 70s, because that's when we invented weather balloons :) but we have even further back information, through the field of Paleoclimate, where we do things like measuring C02 concentration of bubbles in polar ice sheets, dating back as much as 800,000 years ago. We can also use tree rings (hundreds of years, or thousands if fossilized), "corals, stalactites and stalagmites, dust sediments, fossil pollen, peat, lake sediment, and marine sediment" to measure climate change over millenia, no need for satellites! Want to play with all the data on your own? https://github.com/KKulma/climate-change-data https://github.com/KKulma/climate-change-data Her's a curated list of all sorts of data you can play with. https://openclimatedata.net/ https://openclimatedata.net/ Here's some jupyter notebooks! What data is missing that you think it's "not enough?"

Do you have any idea how much of the earth's land surface (to say nothing of its enormous oceanic heat sink) was covered by temperature observation before 1979? We're talking about a few times a day at a few hundred locations, over a few hundred years. Most of the temperature data before 1800 is from SE England; from 1900 onwards, the only better data are from the continental US. All amounting to a miniscule fraction of the data needed for a model...if the system were closed. It's not. No one has any idea what the sun (chief driver of earth's climate) will do next.

Let's apply your rigorous scientific standard and see if we can figure out how much of earth's surface was covered by ocean in 1979... hmm... well we have no satellite observations. We have a decent amount of maps, but, those are just from scattered naval mapmaking activities, really only engaged in by a handful of countries across the entire globe. I'm not convinced the ocean was all that vast before 1979. Do you have better evidence? How do you even know how deep it may have been? What, from a couple depth readings here and there over a few centuries? Sorry, it's going to take more than that to convince me.
