Geoengineering solutions to climate change cannot stop the
increasing acidity of the oceans, conservationists warn Large
scale “geoengineering” solutions to climate change will not
reverse rising acidity in the oceans which damages marine life,
conservationists have warned. The International Union for
Conservation of Nature (IUCN) issued a call at the UN climate
talks in Durban for countries to urgently address the issue of
ocean acidification, caused by greater levels of carbon dioxide
in the atmosphere. The oceans absorb around a quarter of the
carbon dioxide humans put into the atmosphere each year, the
IUCN said, but the gas dissolving into the seas causes the water
to become more acidic. The IUCN said the acidity of the world’s
oceans had increased by 30% since the beginning of the
Industrial Revolution, and could continue at an unprecedented
rate in the coming decades. But while ocean acidification has
the same cause as climate change – increasing amounts of CO2 in
the atmosphere – not all the solutions
