As a resource development manager at Modis, Joe Arrigo is responsible for prospecting candidates to fill positions at IT and engineering firms throughout Northern California. Joe Arrigo formerly worked as a legacy energy advisor at SolarCity, and is a proponent of enacting measures to protect the planet from climate change.
A recent study released by the International Union for Conservation of Nature (IUCN) suggests that climate change may be driving oxygen from oceans at an exacerbated rate. It has been known for decades that nutrient pollution of chemicals like phosphorus and nitrogen has been contributing to the depletion of oxygen in the ocean, but the IUCN believes the effects of climate change are a major reason there are now 700 ocean sites suffering from low oxygen. By comparison, there were only 45 sites in the 1960s.
Marlin, tuna, some sharks, and many other species require higher levels of oxygen, and could be threatened if recent trends continue. The authors of the IUCN study suggested these animals are beginning to move to shallower areas of the sea. While this helps with oxygen intake, it makes those species more susceptible to over-fishing. The world’s oceans could lose as much as 4 percent of their oxygen by 2100 without major emission reductions on a global scale.
