The latest IPCC report details observed effects of climate change on the ocean and cryosphere (really really cold places), which are altering the environment from the highest mountain peaks to the lowest depths of the ocean. The implications for our world are significant. The ocean, which has been absorbing 90% of the excess heat we produce, is giving way to critical levels of acidity and hypoxia threatening the foundation of all marine life. Sea level rise caused by melting ice and thermal expansion threatens to transform once-in-a-century sea level events into regularly occurring annual events by 2050. As if that were not enough, arctic sea ice is decreasing, marine heatwaves are accelerating, permafrost is melting, and planet-scale ocean currents are slowing. If you want to learn more, you've come to the wrong place. You'll find nothing here but rants and nonsensical metaphors.

It's the AA Boys on the IPCC SROCC rn.
