- Are We Destroying the Oceans? (Time.com)
"But human-related injury to the oceans is rife. We have fished out an estimated 90% of the major commercial fish species that swim the high seas, including the giant and endangered blue fin tuna. The trawlers carrying out that destruction are raking the ocean floor, turning parts of the once vibrant continental shelf into so much mud. Climate change is warming the oceans, disrupting the fundamental structure of the marine food pyramid and destroying coral reefs. Meanwhile, increased concentrations of CO2 in the atmosphere are making the seas acidic, which threatens to kill off species in large numbers. 'The ocean is becoming a desert,' says Jeremy Jackson, the director of the Center for Marine Biodiversity and Conservation at the Scripps Institution of Oceanography."
"Pollution that has washed off the land — from sewage that contains chemical toxins to nitrate fertilizer from farmland — has infected the oceans, destroying once vibrant coastal waters. But it's a problem we barely notice, since for many of us the oceans are distant and out of sight." 04-10

"The carbon dioxide data (red curve), measured as the mole fraction in dry air, on Mauna Loa constitute the longest record of direct measurements of CO2 in the atmosphere. They were started by C. David Keeling of the Scripps Institution of Oceanography in March of 1958 at a facility of the National Oceanic and Atmospheric Administration [Keeling, 1976]. NOAA started its own CO2 measurements in May of 1974, and they have run in parallel with those made by Scripps since then [Thoning, 1989]. The black curve represents the seasonally corrected data."
The chart shows that CO2 was around 310 parts per million in 1958 and is 392 in 2011. 05-11

"CO2Now.org distributes the world's latest data for atmospheric CO2 as measured at the Mauna Loa Observatory in Hawaii. This is where high-precision CO2 monitoring was started in March 1958 by Dr. Dave Keeling of the Scripps Institution of Oceanography. The Mauna Loa Observatory is a remote location where CO2 is well mixed in the atmosphere, more than two miles above sea level." 06-12
