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.

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 !!!

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 ( and

( 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…

Watts Up With That?

Update: the IPCC edifice is crumbling, see The state of climate science: ‘fluxed up’

This post will be a sticky for awhile, new posts will appear below it. – Anthony

Dialing Back the Alarm on Climate Change

A forthcoming report points lowers estimates on global warming

by Dr. Matt Ridley

Later this month, a long-awaited event that last happened in 2007 will recur. Like a returning comet, it will be taken to portend ominous happenings. I refer to the Intergovernmental Panel on Climate Change’s (IPCC) “fifth assessment report,” part of which will be published on Sept. 27.

There have already been leaks from this 31-page document, which summarizes 1,914 pages of scientific discussion, but thanks to a senior climate scientist, I have had a glimpse of the key prediction at the heart of the…

Watts Up With That?

This NOAA report was released today, and it claims to see an AGW link in half of the severe weather events of 2012 they studied. I’ll comment in detail later, but for now I’ll simply provide the report, and this reminder from the editors of Nature last year while all the vain attempts at linking severe weather and AGW were unfolding:

Better models are needed before exceptional events can be reliably linked to global warming.

Human influences are having an impact on some extreme weather and climate events, according to the report Explaining Extreme Events of 2012 from a Climate Perspective released September 5, 2013 by the Bulletin of the American Meteorological Society. Scientists from NOAA served as three of the four lead…
