Researchers Say Rising Sea Levels Caused by Increasing CO2 Concentrations

Leigh Hutchens — Fri, 04 Jan 2013 11:18:19 +0000

Researchers at the National Oceanography Centre, Southampton have compared reconstructions of atmospheric CO2 sea level concentrations over the past 40 million years, and they have determined that greenhouse gases equaling 400 parts per million, a concentration similar to today’s rates, were associated with a rise in sea level by 9 meters. The data used by […]

CO2 measurements across the Arctic recorded a milestone value of 400 parts per million (ppm), for the first time in 800,000 years. Can you imagine what this means to the planet, to us and to our children’s future? In the pre-industrial era (before 1750) the concentration was about 280 ppm, and fairly recently the number […]

Corals Deeply Affected by Increasing Atmospheric CO2, Scientists Say

The increasing CO2 concentration in air is having a profound impact on corals in the most unforeseen ways. It had been previously thought that CO2 would affect the calcium structure of the coral skeleton, but an international team of researchers proved something that’s deeper: CO2 affects the very core of the corals: their genes. “Every […]
