CO2 Levels Likely To Stay Above 400PPM For The Rest of Our Lives, Study Shows (inhabitat.com)
An anonymous reader writes: A new study from the UN's Intergovernmental Panel on Climate Change (IPCC) shows that carbon dioxide (CO2) concentrations in the atmosphere are likely to remain above 400 parts per million (ppm) for many years. Specifically, scientists forecasted that levels would not dip below 400pm in "our lifetimes." The CO2 concentrations of "about 450ppm or lower are likely to maintain warming below 2 degrees Celsius over the 21st century relative to pre-industrial levels." However, lead author on the paper Richard Betts said we could pass that number in 20 years or less. In an article on The Guardian, he said even if we reduce emissions immediately, we might be able to delay reaching 450ppm but "it is still looking like a challenge to stay below 450ppm." El Nino has played a significant role in climbing carbon dioxide levels, but it's likely we'll see higher CO2 levels than the last large El Nino storm during 1997 and 1998 because "manmade emissions" have risen by 25 percent since that storm, according to The Guardian. Met Office experts predicted in November 2015 that in May 2016 "mean concentrations of atmospheric CO2" would hit 407.57ppm -- the actual figure was 407.7ppm. The NOAA reported during 2015 that the "annual growth rate" of CO2 in the atmosphere rose by 3.05ppm. NOAA lead scientist Pieter Tans said, "Carbon dioxide levels are increasing faster than they have in hundreds of thousands of years. It's explosive compared to the natural processes."
overpopulation isn't an issue
Overpopulation is the only reason we have anthropogenic global warming in the first place.

The messages, which span 13 years, show a few scientists in a bad light, being rude or dismissive. An investigation is underway, but there’s still plenty of evidence that the earth is getting warmer and that humans are largely responsible.
Some critics say the e-mails negate the conclusions of a 2007 report by the Intergovernmental Panel on Climate Change, but the IPCC report relied on data from a large number of sources, of which CRU was only one.
E-mails being cited as “smoking guns” have been misrepresented. For instance, one e-mail that refers to “hiding the decline” isn’t talking about a decline in actual temperatures as measured at weather stations. These have continued to rise, and 2009 may turn out to be the fifth warmest year ever recorded. The “decline” actually refers to a problem with recent data from tree rings.
The "trick," which was used in a paper published in 1998 in the science journal Nature, is to combine the older tree ring data with thermometer data. Combining the two data sets can be difficult, and scientists are always interested in new ways to make temperature records more accurate.
Tree rings are a largely consistent source of data for the past 2,000 years. But since the 1960s, scientists have noticed there are a handful of tree species in certain areas that appear to indicate temperatures that are warmer or colder than we actually know they are from direct thermometer measurement at weather stations.
"Hiding the decline" in this email refers to omitting data from some Siberian trees after 1960. This omission was openly discussed in the latest climate science update in 2007 from the IPCC, so it is not "hidden" at all.
Why Siberian trees? In the Yamal region of Siberia, there is a small set of trees with rings that are thinner than expected after 1960 when compared with actual thermometer measurements there. Scientists are still trying to figure out why these trees are outliers. Some analyses have left out the data from these trees after 1960 and have used thermometer temperatures instead.
Techniques like this help scientists reconstruct past climate temperature records based on the best available data.
Much has been made about emails regarding a certain paper that some scientists did not think should have been published in a peer-reviewed academic journal. These emails focus on a paper on solar variability in the climate over time. It was published in a peer-reviewed journal called Climate Research, but under unusual circumstances. Half of the editorial board of Climate Research resigned in protest against what they felt was a failure of the peer review process. The paper, which argued that current warming was unexceptional, was disputed by scientists whose work was cited in the paper. Many subsequent publications set the record straight, which demonstrates how the peer review process over time tends to correct such lapses. Scientists later discovered that the paper was funded by the American Petroleum Institute.
In a later e-mail, Phil Jones references two other papers he didn't hold in high esteem. "I can't see either of these papers being in the next IPCC report. Kevin and I will keep them out somehow - even if we have to redefine what the peer-review literature is!"
Yet, the papers in question made it into the IPCC report, indicating that no restrictions on their incorporation were made. The IPCC process contains hundreds of authors and reviewers, with an e
