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.

Annunci

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 !!!

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.

NASA GISS: Research in Climate Modeling
GISS Research Global Climate Modeling. The climate modeling program at GISS is primarily aimed at the development of three-dimensional general circulation models (GCMs) and coupled atmosphere-ocean models for simulating Earth’s climate system, although some research efforts may include the use and development of two-dimensional energy balance models (EBMs), and one-dimensional radiative-convective models (RCMs). Primary emphasis in the use of the GCMs is placed on investigation of climate sensitivity, including the climate system’s response to such forcings as solar variability, anthropogenic and natural emissions of greenhouse gases and aerosols, etc. A major focus of GISS GCM simulations is to study the potential for humans to impact the climate as well as the impact of a changing climate on society and the environment. GCM developmental research focuses on sensitivity to parameterizations of clouds and moist convection, ground hydrology, and ocean-atmosphere-ice interactions, as well as investigations of more accurate numerical methods. The program also involves development of techniques to infer global cloud properties from satellite radiance measurements of the International Satellite Cloud Climatology Project. Ongoing field and laboratory programs in palynology, paleoclimate reconstruction, and other geophysical sciences provide fundamental climate data for evaluating and validating model predictions.

Environment – Climate Change
Climate ChangeClimate change is already happening and represents one of the greatest environmental, social and economic threats facing the planet. The European Union is working actively for a global agreement to control climate change and is taking domestic action to achieve substantial reductions in its own contribution. It is also developing a European strategy for adapting to climate change. The Fourth Assessment Report (AR4) of the Intergovernmental Panel on Climate Change (IPCC) shows that the Earth’s average surface temperature has risen by 0.76° C since 1850. Most of the warming over the past 50 years is very likely to have been caused by emissions of carbon dioxide (CO2) and other ‘greenhouse gases’ from human activities. Without action to reduce these emissions, the global average temperature is likely to rise by a further 1.8-4.0°C this century, and by up to 6.4°C in the worst case scenario, the IPCC projects. Even the lower end of this range would take the temperature increase since pre-industrial times above 2°C – the threshold beyond which many scientists believe irreversible and possibly catastrophic changes would become more likely.

The European Union has long been at the forefront of international efforts to combat climate change and was instrumental in the development of the two United Nations climate treaties, the 1992 UN Framework Convention on Climate Change (UNFCCC) and the Kyoto Protocol, agreed in 1997.The EU has also been taking steps to limit its greenhouse gas emissions since the early 1990s.

In 2000 the European Commission launched the European Climate Change Programme (ECCP) which has led to the adoption of a wide range of new policies and measures, including the pioneering EU Emissions Trading System.

The Kyoto Protocol requires the 15 countries that were EU members at the time (‘EU-15’) to reduce  their collective emissions in the 2008-2012 period to 8% below 1990 levels. Emissions monitoring and projections show that the EU-15 is well on track to meet this target.

In 2007 EU leaders endorsed an integrated approach to climate and energy policy and committed to transforming Europe into a highly energy-efficient, low carbon economy. They made a unilateral commitment that Europe would cut its emissions by at least 20% of 1990 levels by 2020. This commitment is being implemented through a package of binding legislation.

The EU has also offered to increase its emissions reduction to 30% by 2020, on condition that other major emitting countries in the developed and developing worlds commit to do their fair share under a future global climate agreement. This agreement should take effect at the start of 2013 when the Kyoto Protocol’s first commitment period will have expired.

The Copenhagen Accord reached in December 2009 represents a step towards such an agreement. The EU is pressing for a global deal that is ambitious, comprehensive and legally binding.
