Methane in the gas system is a problem or not? Replacing of coal with natural gas has really climate benefits? Recent studies help us to form new way to thinking about climate change and GHG effect.
There’s a lot of hullabaloo recently about Natural Gas being too leaky to be a good substitute for coal. The claim is based on the fact that methane has a much larger GHG potential than carbon dioxide. But, the study those claims are based on can be interpreted two ways. I tend to think that the leak issue might be overblown, because if you are a producer, leaks mean money literally going into thin air. There’s a high incentive to fix leaks. Abandoned oil and gas wells, cited in the study, would of course be an exception.
The other reason is the IPCC, which produced this graph in the AR5 draft showing that methane just isn’t cooperating with models, and measurements are out of bounds with projections. Methane just doesn’t seem to be much of a problem:

A very interesting article on a anomalous levels of molecular chlorine in the atmosphere in Alaska.
Take a look !!!
From the Georgia Institute of Technology
Scientists studying the atmosphere above Barrow, Alaska, have discovered unprecedented levels of molecular chlorine in the air, a new study reports.
Molecular chlorine, from sea salt released by melting sea ice, reacts with sunlight to produce chlorine atoms. These chlorine atoms are highly reactive and can oxidize many constituents of the atmosphere including methane and elemental mercury, as well activate bromine chemistry, which is an even stronger oxidant of elemental mercury. Oxidized mercury is more reactive and can be deposited to the Arctic ecosystem.
The study is the first time that molecular chlorine has been measured in the Arctic, and the first time that scientists have documented such high levels of molecular chlorine in the atmosphere.
“No one expected there to be this level of chlorine in Barrow or in polar regions,” said Greg Huey, a professor in the School of Earth and Atmospheric…

This year, October 22/23, they are bringing in a comedian (no relation):
Carbon pollution is not only disrupting our lives, it’s hitting our wallets. Comedian and musician Reggie Watts shows how, laying out the billion-dollar connection between fossil-fuel energy and dirty weather events like Superstorm Sandy caused by carbon pollution.
I guess he didn’t read the recent IPCC AR5 report that showed no connections of climate change/global warming with severe weather. In a year when we’ve had the least number of wildfires in 30 years and well below the decadal average, plus a near record low in tornadoes, and a hurricane season that has gone bust,Gore is pushing a dead issue. See why on the WUWT Extreme Weather page
So as this screencap from his latest propaganda video shows, setting fire to orchids seems to be the way Gore is fawning for attention getting the message across…

“Global change and its implication on the system services and society”
This post is 4 my followers
Planetvoice is a little blog and the stats …tell me that you love
So….this post it is 4 you all …..I love u guyz
TNX U SO MUCH
LISTEN THE PLANET
Listen it ….listen…PLANETVOICE !!!!!
A very interesting post ………..tnx to WUWT!!!
From the University of Colorado at Boulder
CU-Boulder researchers use climate model to better understand electricity in the air
Electrical currents born from thunderstorms are able to flow through the atmosphere and around the globe, causing a detectable electrification of the air even in places with no thunderstorm activity.
But until recently, scientists have not had a good understanding of how conductivity varies throughout the atmosphere and how that may affect the path of the electrical currents. Now, a research team led by the University of Colorado Boulder has developed a global electric circuit model by adding an additional layer to a climate model created by colleagues at the National Center for Atmospheric Research (NCAR) in Boulder.

Guest essay by Marlo Lewis
Okay, they don’t do so in as many words. But in addition to being more confident than ever (despite a 16-year pause in warming and the growing mismatch between model projections and observations) that man-made climate change is real, they are also more confident nothing really bad is going to happen during the 21st Century.
The scariest parts of the “planetary emergency” narrative popularized by Al Gore and other pundits are Atlantic Ocean circulation shutdown (implausibly plunging Europe into a mini-ice age), ice sheet disintegration raising sea levels 20 feet, and runaway warming from melting frozen methane deposits.

The Working Group I contribution to the IPCC’s Fifth Assessment Report (AR5) considers new
evidence of climate change based on many independent scientific analyses from observations of
the climate system, paleoclimate archives, theoretical studies of climate processes and simulations
using climate models. It builds upon the Working Group I contribution to the IPCC’s Fourth
Assessment Report (AR4), and incorporates subsequent new findings of research. As a
component of the fifth assessment cycle, the IPCC Special Report on Managing the Risks of
Extreme Events to Advance Climate Change Adaptation (SREX) is an important basis for
information on changing weather and climate extremes.
