NOAA Study: All Indicators Show Climate Change is Undeniable

A new study from the US National Oceans and Atmospheric Administration shows that climate change is ‘undeniable’ — but does anyone really believe that will silence the deniers?

The NOAA study drew on up to 11 different indicators of climate, and found that each one pointed to a world that was warming owing to the influence of greenhouse gases, said Peter Stott, head of climate monitoring at the UK’s Met Office, one of the agencies participating.

Seven indicators were rising, he said. These were: air temperature over land, sea-surface temperature, marine air temperature, sea level, ocean heat, humidity, and tropospheric temperature in the “active-weather” layer of the atmosphere closest to the earth’s surface. Four indicators were declining: Arctic sea ice, glaciers, spring snow cover in the northern hemisphere, and stratospheric temperatures.

Mr Stott said: “The whole of the climate system is acting in a way consistent with the effects of greenhouse gases.” “The fingerprints are clear,” he said. “The glaringly obvious explanation for this is warming from greenhouse gases.”

This is really bad news; not a single indicator contradicts the conclusion that we’re approaching a catastrophic tipping point. And it gets even worse.

Another newly released study has shown that phytoplankton, the basis of the ocean’s entire food chain, has declined over the past century by 40 percent.

The microscopic plants that support all life in the oceans are dying off at a dramatic rate, according to a study that has documented for the first time a disturbing and unprecedented change at the base of the marine food web.

Scientists have discovered that the phytoplankton of the oceans has declined by about 40 per cent over the past century, with much of the loss occurring since the 1950s. They believe the change is linked with rising sea temperatures and global warming.
