I could cite individual observations and reports, but the field is difficult to summarize in a single HN comment. There are many factors that we cannot completely oversee, primarily tipping points (disappearing reflective polar caps) and feedback loops (melt of permafrost with methane release).

More concretely, have a look at the latest IPCC report [1], page SPM-16. Three of the five scenarios include temperature rises from 3 to 5 °C. Based on the last decade, the world has not reduced total CO2 emissions at all (not even slowed), despite its knowledge about climate change. Therefore, I have reason to believe that the three bad scenarios (intermediate to high CO2 emission), are more likely to happen than scenarios covering halted or little CO2 emission.

so CO2 isn’t increasing our global temperature as much as we had previously projected.

Can you explain how you reached this conclusion?

[egberts1]

Perhaps it’s the science.

You summarize a random number of clickbait news headers from the past 60 years. If this is your main source of information, I would seriously reconsider my behavior for collecting and reviewing relevancy and quality of information.

[egberts1]

that’s the science for you over 60 years.

I still remember Al Gore’s purchase of a San Francisco waterfront property.
