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.

Watts Up With That?

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 !!!

Watts Up With That?

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…

Watts Up With That?

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…

Watts Up With That?

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.

data : IPCC #AR5 Working Group I

Amici, lettori, giornalisti e addetti ai lavori ci siamo!!!
Alla vigilia dell’attesissimo rilascio da parte dell’IPCC del quinto report sul cambiamento climatico,  il mondo si interroga su quali siano a partire dal 2013, i prossimi obiettivi da perseguire per salvaguardare il Pianeta dal Cambiamento Climatico che , oramai, è sempre più evidente ed economicamente e socialmente impattante!!!
La decisione di preparare un quinto report fu presa dai membri durante la loro ventottesima sessione di lavoro tenutasi il 9 e 10 Aprile del 2008 a Budapest in Ungheria.
Ecco a voi un’anticipazione di come sarà strutturato il report e di quali argomenti saranno inclusi….
Il report dovrebbe essere composto da 4 parti; 3 Working Group I,II e III e da un Report di sintesi. Ogni parte includerà una serie di argomenti specifici che concorrerà ad una migliore interpretazione del Report nel suo totale.
Di seguito riportiamo quello che dovrebbe essere lo schema definitivo del Primo Working Group denominato “Climate Change 2013-The Phisical Science Basis ” al quale hanno collaborato 259 autori provenienti da 39 Nazioni con un monumentale lavoro di integrazione e sintesi di oltre 54.000 commenti e analisi specifiche.

Technical  Summary :

           – Introduction

  • Observations: Atmosphere and Surface

  • Observations: Ocean

  • Observations: Cryosphere

  • Information from Paleoclimate Archives

  • Carbon and Other Biogeochemical Cycles

  • Clouds and Aerosols

  • Anthropogenic and Natural Radiative Forcing

  • Evaluation of Climate Models

  • Detection and Attribution of Climate Change: from Global to Regional

  • Near-term Climate Change: Projections and Predictability

  • Long-term Climate Change: Projections, Commitments and Irreversibility

  • Sea Level Change

  • Climate Phenomena and their Relevance for Future Regional Climate Change

A questo “corpus” del primo Working Group dovrebbero essere inoltre annesse 5 Appendici molto interessanti la prima delle quali dovrebbe occuparsi delle proiezioni future di questo report.

Insomma attendiamo con ansia il Report nella sua interezza per leggerlo e trarne oculate, interessanti e soprattutto indicative indicazioni sul percorso che il mondo scientifico indicherà alla società civile e indutriale per salvaguardare al meglio il nostro unico Habitat vitale !!!

Sicuramente Planetvoice pubblicherà in tempo reale tutti i report o almeno un sunto di essi con tutti i collegamenti necessari per una migliore comprensione degli elaborati, ragion per la quale restate connessi oppure cliccate l’RSS feed per essere costantemente aggiornati !!!

Listen The Planet …..listen Planetvoice !!!

tnx to WUWT

Watts Up With That?

Guest essay by Prof. Don J. Easterbrook

The September issue of National Geographic shows sea level midway up the Statue of Liberty, 214 feet above present sea level (Fig. 1) and contains dire images of impending catastrophic sea level rise. Anthony’s excellent responses (http://wattsupwiththat.com/?s=national+geographic) and

(http://wattsupwiththat.com/2010/11/28/freaking-out-about-nyc-sea-level-rise-is-easy-to-do-when-you-dont-pay-attention-to-history/) have demonstrated the utter absurdity of the National Geographic portrayal.

As Anthony points out, at the rate of sea level rise shown by tide gauge records since 1856 at The Battery 1.7 miles away, for sea level to reach that high up the Statue of Liberty would take 23,538 years!

But what about the other assertions in the National Geographic article, such as (1) many graphic images of [what] the future holds, (2) smaller, but still unreasonable sea level rise, (3) doomed cities (Miami and London gone), (4) flooded coastal areas (most of southern Florida submerged), (5) more frequent storm…
