This isn’t a scientific study done in a lab or with computer models. Instead, it’s based on on-site observations in hundreds of places around the globe, showing us significant changes to local conditions already being experienced, mostly by indigenous peoples. This has to be an important study.
Here’s the extract from the research paper:
The study of climate change has been based strongly on data collected from instruments, but how local people perceive such changes remains poorly quantified. We conducted a meta-analysis of climatic changes observed by subsistence-oriented communities.
Our review of 10,660 observations from 2,230 localities in 137 countries shows that increases in temperature and changes in seasonality and rainfall patterns are widespread (≈70% of localities across 122 countries). Observations of increased temperature show patterns consistent with simulated trends in surface air temperature taken from the ensemble average of CMIP5 models, for the period 1955–2005.
Secondary impacts of climatic changes on both wild and domesticated plants and animals are extensive and threaten the food security of subsistence-oriented communities. Collectively, our results suggest that climate change is having
profound disruptive effects at local levels and that local observations can make an important contribution to understanding the pervasiveness of climate change on ecosystems and societies.
Here’s an example of one of the maps. I know it’s tough to read. If you link into the article you can see the map with more clarity.
