James E. Hansen (2008) – Climate Threat to the Planet: The Venus Syndrome – The Bjerknes Lecture, American Geophysical Union, San Francisco – 17/12/2008 “The Venus syndrome is the greatest threat to the planet, to humanity’s continued existence… Now the danger that we face is the Venus syndrome. There is no escape from the Venus Syndrome. Venus will never have oceans again.”
James Hansen et al – Earth’s Energy Imbalance: Confirmation and Implications – Science 308:1431-1435 – 03/06/2005 – 15 authors – Peer reviewed “This imbalance is confirmed by precise measurements of increasing ocean heat content over the past 10 years. Implications include (i) the expectation of additional global warming of about 0.6 ºC without further change of atmospheric composition; (ii) the confirmation of the climate system’s lag in responding to forcings, implying the need for anticipatory actions to avoid any specified level of climate change; and (iii) the likelihood of acceleration of ice sheet disintegration and sea level rise.”
James Hansen et al – Earth’s Energy Imbalance: Confirmation and Implications – Science 308:1431-1435 – 03/06/2005 – 15 authors- Peer reviewed “The thermal inertia of the ocean, with resulting unrealized warming ‘‘in the pipeline,’’ combines with ice sheet inertia and multiple positive feedbacks during ice sheet disintegration to create the possibility of a climate system in which large sea level change is practically impossible to avoid.”
James Hansen et al (2008) – Target Atmospheric CO2: Where Should Humanity Aim? – Open Atmospheric Scientific Journal 2:217-231 – 10 authors- Peer reviewed “The expanded time scale for the industrial era (fig) reveals a growing gap between actual global temperature … and equilibrium … temperature response based on the net estimated climate forcing … Ocean and ice sheet response times together account for this gap, which is now 2.0 °C.”
Marc Bowen (2008) – Censoring Science. Inside the Political Attack on Dr. James Hansen and the Truth of Global Warming – Penguin Group, 2008 – pp. 61:62 “On the 20th of January, as it began to appear that Yime magazine would let the story flip, Jim gave roughly the same information to an old contact, Andrew Revkin, the lead global warming correspondent for The New York Times. On the 24th, Larry Travis was hit and severely injured by a truck as he walked across Bradway on his way to work, Jim’s (Hansen) car was also broken into around that time, and the house in New Jersey in which he and Annie had raised their children burned to the ground. Darnell Cain, Jim’s assistant admits to being ‘sufficiently lazy and negligent to not update the NASA public records with Jim’s new address when he moved to Pennsylvania’”
H. D. Matthews and Ken Caldeira (2008) – Stabilizing climate requires near-zero emissions – Geophysical Research Letters 35, L04705, doi:10.1029/2007GL032388 – Department of Geography, Planning and Environment, Concordia University, Montreal; Department of Global Ecology, Carnegie Institution of Washington, Stanford – Peer reviewed “To hold climate constant at a given global temperature requires near-zero future carbon emissions … future anthropogenic emissions would need to be eliminated in order to stabilize global-mean temperatures … any future anthropogenic emissions will commit the climate system to warming that is essentially irreversible on centennial timescales”.
V. Ramanathan, Y. Feng – On avoiding dangerous anthropogenic interference with the climate system: Formidable challenges ahead – Proceedings of the National Academy of Sciences 105: 14245–14250 – 23/11/2008 – Scripps Institution of Oceanography, University of California at San Diego – Peer-reviewed “Even the most aggressive CO2 mitigation steps as envisioned now can only limit further additions to the commited warming, but not reduce the already commited GHGs warming of 2,4 ºC.”
James Hansen et al (2008) – Target Atmospheric CO2: Where Should Humanity Aim? – Open Atmospheric Scientific Journal 2:217-231 – 10 authors – Peer reviewed “If humanity wishes to preserve a planet similar to that on which civilization developed and to which life on Earth is adapted, paleoclimate evidence and ongoing climate change suggest that CO2 will need to be reduced from its current 385 ppm to at most 350 ppm, but likely less than that. The largest uncertainty in the target arises from possible changes of non-CO2 forcings. An initial 350 ppm CO2 target may be achievable by phasing out coal use except where CO2 is captured and adopting agricultural and forestry practices that sequester carbon. If the present overshoot of this target CO2 is not brief, there is a possibility of seeding irreversible catastrophic effects.”

Primer premio Fundación Biodiversidad
Este blog ha sido agraciado con el 1r Premio de la Fundación Biodiversidad en la categoría de comunicación del cambio climático - blogs (convocatoria 2010)
La humanidad se encuentra frente a una de las mayores disyuntivas que cabe imaginar. El sistema climático terrestre parece haber sido definitivamente desestabilizado, mientras la inmensa mayoría de la población vive ajena a un fenómeno llamado a marcar nuestras vidas de forma determinante y abrumadora. Comunidad científica, medios de comunicación y clase política se encuentran aturdidos por el fenómeno y sin respuestas adecuadas a la magnitud del desafío. Cuando las élites fracasan, es la hora de la gente.
