A lot of fake data was pushed or extrapolated to try and fright people into doing something.
Fact is that the data at the time, the measurements at the time, didn't suggest that the glaciers were going to disappear that quickly. The models made 20 years ago weren't perfect, but we are still roughly in line with the predictions from them. More sources of data have been added since then, climate science has improved.
The big problem is that people like to cherry pick one piece of data and use it to "debunk" global warming/climate change when there are many sources of data used in conjunction to support it.
No one gives a shit about your websearches. No one gives a shit that it's the "coldest winter you remember". No one gives a shit that Antarctica is gaining ice (while Greenland loses ice at something like 5x the rate).
The fact is that our species will have to deal with the effects of climate change in the decades to come, and we should start doing things to improve our resilience against it instead of bickering over whether it is happening at all.
As nations we should be working to reduce our emissions, not sweeping cuts within a year but slow reductions by moving to cleaner technologies and less wasteful use of resources. We should be looking at what we can start doing now to mitigate the problems we will have in the future as drought patterns change and more violent storms hit, problems that could cost nations billions of dollars in a year.
Instead a lot of nations are just sitting on their hands because governments can't decide if climate change is even a thing, or people protest against actions they want to take against it.
