While carbon emissions are often at the hot topic center of the global warming debate one group of scientists say CO2 could have one positive side effect, helping us avoid another ice age.
The last Ice Age ended nearly 11,500 years ago and while scientists are not quite sure when the next one will begin they had believed it would begin within 1,5000 years before CO2 emissions spiraled out of control.
Luke Skinner from Cambridge University tells Nature Geoscience:
“At current levels of CO2, even if emissions stopped now we’d probably have a long interglacial duration determined by whatever long-term processes could kick in and bring [atmospheric] CO2 down.”
According to the research group CO2 would have to dip below 240 parts per million (ppm) before the glaciation could begin while the current level is closer to 390ppm.
In another research project a group of scientists revealed that even if carbon emissions were shut off completely at this very moment it would take nearly 1,000 years for proper ice age conditions to be their stabilization process.
While more research must still be conducted various groups are embracing the discovery including the Global Warming Policy Foundation who rediscovered a 1999 essay that describes how an Ice Age would “render a large fraction of the world’s major food-growing areas inoperable.”
Irregardless of the lack of an ice age, if the earth is heating up because of man made emissions the negative side effects could far outweigh another Ice Age.
Do you think CO2 Emissions are doing more or less harm then scientists believe?
