2. the higher levels of carbon dioxide in the atmosphere is making the global climate more extreme...

so it gets WARMER than usual and also COLDER than usual once in a while. The hotter weather gets all the headlines, but AFAIK the cold end of the spectrum happens too at times. Weather is just more extreme than it used to be, on a more regular basis.

Future climate change and associated impacts will differ from region to region.[13][14] Anticipated effects include increasing global temperatures, rising sea levels, changing precipitation, and expansion of deserts in the subtropics.[15] Warming is expected to be greater over land than over the oceans and greatest in the Arctic, with the continuing retreat of glaciers, permafrost and sea ice. Other likely changes include more frequent extreme weather events such as heat waves, droughts, heavy rainfall with floods and heavy snowfall;[16] ocean acidification; and species extinctions due to shifting temperature regimes.
