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:

An interesting interview taken from the convention of the Società Italiana per le scienze del clima www.sisclima.it  named

“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

IT …..

So….this post it is 4 you all …..I love u guyz

TNX U SO MUCH

LISTEN THE PLANET

Listen it ….listen…PLANETVOICE !!!!!

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 !!!

Caring for Climate – led by the UN Global Compact, the UN Environment Programme and

the secretariat of UN Framework Convention on Climate Change – will organize the

inaugural Caring for Climate Business Forum: Innovation, Ambition, Collaboration at

COP19/CMP9 on 19-20 November 2013 in Warsaw, Poland.

 

Join corporate climate champions at 1st Caring for Climate Business Forum to

 

Scale-up business innovation on climate change

Encourage business and Governments to raise ambition on climate policies
Spark collaboration among business, investors, civil society, UN and Governments

 

The Business Forum will showcase the contributions that business and investors can make towards climate action while providing a high-level leadership platform with policymakers.

La National Climate Change Adaptation Research Facility (NCCARF) si riunirà in una conferenza che si terrà a Sydney dal 25 al 27 giugno 2013.

L’appuntamento è ….inutile dirvelo….. di enorme importanza .

 

La conferenza riunirà gli utenti finali e i ricercatori di tutta l’Australia e non solo con il fine di condividere esperienze, programmi ed interventi da attualizzare e implementare, in un contesto mirato a focalizzare strategie di ricerca e di adattamento al cambiamento climatico in atto.
La conferenza sarà il nesso tra la comunità di ricerca e gli utenti delle informazioni relative alle strategie di adattamento climatico.
Sulla scia del successo della convention NCCARF-CSIRO del 2012, si sono ottenuti stanziamenti per circa $35 milioni per la ricerca sulle tematiche relative all’adattamento e la costruzione di reti di ricerca formale e informale organizzate in numerose partnerships, questo sarà l’evento ambientale legato al Climate Change più importante di quest’anno dell’Australia, concentrato unicamente sull’adattamento al cambiamento climatico e sulle strategie da adottare in merito per il 2013.

Negli strati superiori dell’atmosfera il vapor acqueo, un potente gas ad effetto serra, stà diminuendo ; uno studio basato su osservazioni della NASA ci spiega il perchè e le conseguenze!

Watts Up With That?

Guest post submitted by Ken Gregory, Friends of Science.org

An analysis of NASA satellite data shows that water vapor, the most important greenhouse gas, has declined in the upper atmosphere causing a cooling effect that is 16 times greater than the warming effect from man-made greenhouse gas emissions during the period 1990 to 2001.

The world has spent over $ 1 trillion on climate change mitigation based on climate models that don’t work. They are notoriously poor at simulating the 20th century warming because they do not include natural causes of climate change – mainly due to the changing sun –  and they grossly exaggerate the feedback effects of greenhouse gas emissions.

Most scientists agree that doubling the amount of carbon dioxide (CO2) in the atmosphere, which takes about 150 years, would theoretically warm the earth by one degree Celsius if there were no change in evaporation, the…

Interesting paper that shows a positive impact of warming up to 2.0C and a negative impact afterwards, suggesting that some warming is beneficial, but a lot of warming is not. tnx to WUWT and Richard T. and Lomborg B.

Watts Up With That?

I thought this paper was interesting, and it was (as part of a Twitter exchange) sent to me by request (thanks to Both Richard Tol and Bjørn Lomborg). I found figure 8 (shown below as part of the preview on Science Direct) to be interesting because it shows a positive impact of warming up to 2.0C and a negative impact afterwards, suggesting that some warming is beneficial, but a lot of warming is not. All things in moderation I suppose. – Anthony.

Abstract

A survey of the economic impact of climate change and the marginal damage costs shows that carbon dioxide emissions are a negative externality. The estimated Pigou tax and its growth rate are too low to justify the climate policy targets set by political leaders. A lower discount rate or greater concern for the global distribution of income would justify more stringent climate policy, but would imply an…

The UN climate talks failed to deliver increased cuts to carbon pollution, nor did they provide any credible pathway to $100 billion per year in finance by 2020 to help the poorest countries deal with climate change, according to the 700 NGOs who are members of Climate Action Network-International (CAN-I).

Two weeks ago, just prior to the start of these negotiations,…

The Climate Action Network (CAN) is a worldwide network of over 700 Non-Governmental Organizations (NGOs) in over 90 countries working to promote government and individual action to limit human-induced climate change to ecologically sustainable levels.

CAN members work to achieve this goal through information exchange and the coordinated development of NGO strategy on international, regional, and national climate issues.
