I guess if you want to go from 0 to educated and alarmed, I'd start with some policy and overview of climate dynamics, and then dive into how our ecosystems are already seeing cascades and collapses.

Policy Overview:
How to achieve the Sustainable Development Goals within Planetary Boundaries: https://www.stockholmresilience.org...20Goals_WEB.pdf

The Shared Socioeconomic Pathways and their energy, land use, and greenhouse gas emissions implications: An overview: https://www.sciencedirect.com/science/article/pii/S0959378016300681

[Add in the IPCC SROCC here when it comes out as an authoritative source on the cryosphere]

Ecosystem Impacts:
Decline in insect biomass (the only major mass extinction that included significant amounts of insects was the Permian-Triassic): https://en.wikipedia.org/wiki/Decline_in_insect_populations
The end of that article is especially depressing imo:


Thiamine deficiency in wild animals is a serious threat to biodiversity: https://www.su.se/english/research/...ersity-1.377252

Biological annihilation via the ongoing sixth mass extinction signaled by vertebrate population losses and declines: https://www.researchgate.net/public...es_and_declines

And an area that I have personally believe will cause mid-century food crises, euphotic ocean acidification and its impacts on the carbonate cycle:
History of Seawater Carbonate Chemistry, Atmospheric CO2, and Ocean Acidification: https://courses.pbsci.ucsc.edu/eeb/bioe159/wp-content/uploads/2018/01/Zeebe-et-al.-2012.pdf (this is an absolutely phenomenal primer on carbon cycles in the ocean)
