The GISS temp data has been manipulated [1]. We don't have global temperature data for the land and the sea going back to 1880. The satellite weather era began in the late 70s. Even for land based records, outside of the first world they are very sparse prior to the 1950s. The temperatures had dropped so much by the 1970s that there was an actual ice age scare. They even hired Leonard Nimoy to pitch it. [2] The GISS data set shows this as a blip and it's a sad joke. 1) https://youtu.be/spyJhgVbvVY https://youtu.be/spyJhgVbvVY 2) https://youtu.be/mOC7ePWCHGk https://youtu.be/mOC7ePWCHGk

  Sorry but you are simply wrong. Tony Heller (your first video) has been debunked so many times it's a wonder he still makes videos. If you want to say GISS data is manipulated, please come up with solid evidence from peer reviewed sources. Their methods have been thoroughly peer reviewed, something that cannot be said of Tony Heller. Why did they hire Leonard Nimoy, not an actual climate scientist? The doomsday ice age scare of the 70s has been exaggerated to the point of breaking. The vast majority of scientific papers in those times showed global warming is the issue. There was some cooling starting in the 40s, mainly due to aerosol pollution of the atmosphere. This issue was tackled. Now we're left with CO2 and other greenhouse gases. As for the temperature records, please look up how temperature proxies (tree rings, ice cores...) can be used to reconstruct global temperature. It's not like we know the temperature from 2000 years ago because the Romans had a notebook and measurement stations spanning the globe.
