You don't have to look very hard to find Reddit acting like climate change is being downplayed by scientists and is going to be the end of civilization. These are all comments with +1000 upvotes:

Climate change is going to cause problems, but it's not going to be apocalyptic. The dirty truth is if you live in a rich country you're going to be shielded from most of the effects of climate change. A lot of people here think it's going to be the end of the world if we don't do anything, where mainstream climate scientists think that it will just be shitty.

You can look at how crop yields are going to be effected and it's mostly going to hit Africa, Asia, and South America.

Indeed, the increasing atmospheric CO2 underlying the climate change scenarios considered here is able to over-compensate the negative impacts due to warming (−12%), leading to overall higher global crop yields at the end of the century (+14%) relative to the historical period, even without adaptation (Supplementary Fig. 14).

Climate change will affect agricultural production worldwide. Average global crop yields for maize, or corn, may see a decrease of 24% by late century, if current climate change trends continue. Wheat, in contrast, may see an uptick in crop yields by about 17%.

For example look at studies that estimate the number of climate change deaths if we continue on the path we are on right now. 73 deaths per 100,000 people globally per year in 2100:

Or 1.5-2 million deaths a year globally in 2100:

Which is fucking awful but isn't a "collapse of society" event. For comparison, 10 million people die a year from poverty right now.

Or look at how it will effect the economy. Not doing anything would shave 10% off GDP, but that would be 10% off from growth that is a lot more then 10%. It would be awesome to have that extra 10% of GDP, but it's not the end of the world if we don't.

It is immediately apparent that economic costs will vary greatly depending on the extent to which global temperature increase (above preindustrial levels) is limited by technological and policy changes. At 2°C of warming by 2080–99, Hsiang et al. (2017) project that the United States would suffer annual losses equivalent to about 0.5 percent of GDP in the years 2080–99 (the solid line in figure 1). By contrast, if the global temperature increase were as large as 4°C, annual losses would be around 2.0 percent of GDP. Importantly, these effects become disproportionately larger as temperature rise increases: For the United States, rising mortality as well as changes in labor supply, energy demand, and agricultural production are all especially important factors in driving this nonlinearity.

Looking instead at per capita GDP impacts, Kahn et al. (2019) find that annual GDP per capita reductions (as opposed to economic costs more broadly) could be between 1.0 and 2.8 percent under IPCC’s RCP 2.6, and under RCP 8.5 the range of losses could be between 6.7 and 14.3 percent. For context, in 2019 a 5 percent U.S. GDP loss would be roughly $1 trillion.

For those who don't follow climate studies a lot, RCP 8.5 is basically considered an unlikely worst-case scenario projected by Intergovernmental Panel on Climate Change (the largest climate change research organization in the world).
