IPCC Scientist Admits Last Big Rise In CO2 Was After A Very Warm Year
There are two points of view in any argument or statement put forward, nothing new there, but what make this particular story interesting is that both points of view come from the same side, in this case the warming alarmist fraternity.
Atmospheric CO2 has risen by 2.67 parts per million (ppm) in the last year to a shade over 395 ppm, which 0.04% of the planet’s atmosphere to put the CO2 concentration in perspective.
The central core argument of the Global Warming industry is that CO2 is a greenhouse gas which traps heat in the atmosphere, the planetary mean temperature rises and ergo we all fry, however, observed empirical evidence from other warming events in the past, indicate that CO2 levels increase following warm periods.
Naturally a minute increase in a trace gas essential for life on Earth is the cause for hysteria and crying wolf at the Guardian, where John Vidal is hysterical with fear:
Carbon dioxide levels measured at at Mauna Loa observatory in Hawaii jumped by 2.67 parts per million (ppm) in 2012 to 395ppm, said Pieter Tans, who leads the greenhouse gas measurement team for the US National Oceanic and Atmospheric Administration (NOAA). The record was an increase of 2.93ppm in 1998.
1998 was an abnormally hot year, that once in a century event and that was the last time atmospheric CO2 increased by a warmist record.
The jump comes as a study published in Science on Thursday looking at global surface temperatures for the past 1,500 years warned that “recent warming is unprecedented”, prompting UN climate chief, Christiana Figueres, to say that “staggering global temps show urgent need to act. Rapid climate change must be countered with accelerated action.”
Tans told the Associated Press the major factor was an increase in fossil fuel use. “It’s just a testament to human influence being dominant“, he said. “The prospects of keeping climate change below that [two-degree goal] are fading away.”
The same tired old Green drivel about impending doom linked with the deeply flawed notion that mankind has the power to select and control the weather and climate.
The same story from the warming alarmists at Responding To Climate Change presents a different picture:
But Bill Collins from Reading University’s Department of Meteorology and a contributor to the Intergovernmental Panel on Climate Change’s forthcoming review on climate science, told RTCC data gathered over a short period could be misleading.
“I would urge caution about treating any one year as telling us something really special,” he said.
“There has been a big deal made of this being the second highest annual rise ever – but there is quite a lot of variability in CO2, due to plant ecosystems, so the last highest rise was after a very warm year.
“That was 1998 and not basically due to man-made causes but because it had been a hot year and the soils had given off a lot of CO2 and the plants had not grown strongly – so the year to year variability is often caused by the uptake of plants and trees.
Natural variability, not caused by humans, says it all really.
