#Archaeology Why the @SAAorg needs to move to a hybrid or online conference format for 2022 (a thread) 1.) We cannot say #BlackLivesMatter and simultaneously fly over 10,000 people to Chicago and pack them into dense meeting rooms. We will be directly responsible for more death
2.) As archaeologists we should be terrified of the impacts of the climate crisis, especially after reading the IPCC report. We know that the increases in temperature are far beyond that which humanity has known since they first started to domesticate plants and animals.
3.) We cannot simultaneously claim to hold up global voices while cutting them out of our academic conferences because most of the world cannot (and should not for their own safety) travel to this meeting. This is a matter of equity and ethics.
4.) If you agree please R/T and sign this petition to have the conference move online. Currently the organizers do NOT have this in their plans: ipetitions.com/petition/move-…

As an archaeologist who works on climate, a question I often get is: "But why should we be worried about global warming, the earth has moved through hot and cold periods right?" Here's why.
1.) We live in a fundamentally different world from that of how humans or rather hominids lived the last time we had similar concentrations of atmospheric CO2 to today (2 million years- 800,000 years) source :IPCC 2021.
2.) What was going on with humans between 2 million to 800,000 years ago. Well we were just getting started. Homo habilis and Homo erectus started making some of the first stone tools around this period of time, and had very low population densities, like 10,000 of them.
I'm an archaeologist, and in this thread, I’m going to tell you why our current climate crisis is so terrifying to me. 1.) In this paper, Xu et al demonstrate that humans have concentrated in a really narrow subset of earth's climate. pnas.org/content/117/21…
2.) The production of our current crops and livestock is really limited to this "niche" and has been so for millennia (at least the past 6000 years) when farming and foddering of animals really took off.
3.) We should be terrified by this figure in the paper, which basically shows mean temperatures experienced by humans over the past 6000 years, and predictions for 2070. Its way outside of anything we have known during the period that the economies we rely on today developed.
