Meret eivät happamoidu, korallit eivät häviä,merenpinta ei nouse
The real-world evidence for an ocean acidification crisis, however, is even less persuasive than the real-world evidence for a global warming crisis.
"The world’s oceans are not acidic and are in no danger of becoming so. Acidity and alkalinity are measured by pH balance, on a scale of 1 to 14. Water with a pH of 7 is neutral. A pH below 7 is acidic, and above 7 is alkaline. The pH of the world’s oceans is slightly higher than 8.1—safely alkaline.
Regardless of human carbon dioxide emissions, the world’s oceans are in no danger of becoming acidic any time in the foreseeable future. A 2005 study published in the peer-reviewed journal Nature reports ocean pH was between 8.1 and 8.2 at the dawn of the Industrial Revolution—before humans began emitting significant amounts of carbon dioxide—and remains between 8.1 and 8.2 today. The past 250 years of carbon dioxide emissions have had no significant effect on ocean pH, and there is little reason to believe that will suddenly, catastrophically change.
On the contrary, peer-reviewed scientific studies confirm higher carbon dioxide content will benefit rather than harm marine life"
Eli puheet merien happamoitumisesta ja uhkasta koralleille ovat tuulesta temmattuja.
"No evidence for accelerated sea-level rise' says Royal Netherlands Meteorological Institute – December 12, 2008
Excerpt: In an op-ed piece in the December 11 issue of NRC/Handelsblad, Wilco Hazeleger, a senior scientist in the global climate research group at KNMI, writes: “In the past century the sea level has risen twenty centimeters. There is no evidence for accelerated sea-level rise. It is my opinion that there is no need for drastic measures. It is wise to adopt a flexible, step-by-step adaptation strategy. By all means, let us not respond precipitously"
Eli ei ole todistetta siitä, että merenpinta olisi noussut mitenkään poikkeavasti.
