Global Temperature Projections Could Double as the World Burns
Dahr Jamail16 July, 2018
Two new studies investigating corn and vegetables have warned of an increasing risk of food shocks around the world, along with malnutrition, if ACD continues unchecked, which by all accounts it will, given the governmental refusal to even discuss the actions necessary for mitigation. Both studies were published in the prestigious Proceedings of the National Academy of Sciences and showed how ACD will increase the risk of simultaneous crop failures across the planet’s largest corn-growing regions, as well as sapping nutrients from critical vegetables. For example, an increase of 4 degrees Celsius (4°C) — which is essentially the current trajectory we are on to reach by 2100 — could cut US corn production nearly in half. Meanwhile, the likelihood of simultaneous crop failures for the four biggest corn exporters (US, China, Brazil, Argentina) suffering yield losses of 10 percent or greater increases from 7 percent at 2°C warming to 86 percent at 4°C.
Another study warns
of how ACD already poses a serious threat to the nutritional value of
crops, and a lack of action could well have major global implications
for both food security and global health. The same
study showed that
global crop yields could be reduced by nearly one-third with a 4°C
temperature increase.
But
the food crisis is already current, because drying wells and sinking
land at the heart of the most productive farmland in the US, the
Central Valley of California, are an indication that we are watching
the collapse of this once bountiful area. Large portions of the San
Joaquin Valley have
already sunk nearly
30 feet since the 1920s, with some areas having dropped a staggering
three feet over just the last two years. All of this is the result of
farmers’ relentless pumping of groundwater to offset the lack of
snowpack and rainfall, both of which stem largely from ACD. It is
important to note that the groundwater the farmers are using accounts
for between 30 to 60 percent of the water that all Californians use
each year, depending on how much rain and snow the state gets. The US
Geological Survey stated that
the pumping and resultant sinking of the San Joaquin Valley is “one
of the single largest alterations of the [planet’s] land surface
attributed to mankind.”
Another
sign of the dramatic changes besetting the planet comes from the
Arctic, where a cyclone became
one of the most powerful on record. The fact that it occurred in June
was also noteworthy, as historically these storms don’t normally
begin to hit the Arctic until late summer. Its impacts on what is
left of the ever-shrinking sea ice are, of course, deleterious.
Another recent
report illustrates
how what happens in the Arctic does not stay in the Arctic. The loss
of Arctic sea ice could well cook the tropics by changing critical
ocean currents and altering wind patterns, which will of course cause
dramatic changes across the entire planet.
Look
out your window. Better yet, go outside and feel what is happening.
By early July, cities across the globe set
all-time-high temperature records.
While no single weather event can ever be attributed solely to ACD,
it has been well known for decades now that all of these phenomena
are being driven in part (and most are largely driven) by ACD.
