Gerald Marsh - The purpose of this critique is to help the reader determine whether our understanding of the earth’s climate is adequate to predict the long-term effects of carbon dioxide emissions from the continued burning of fossil fuels, to permit informed public policy decisions.
Climate Change 2001: The Scientific Basis, the Contribution of Working Group I to the Third Assessment Report of the Intergovernmental Panel on Climate Change, the volume is remarkable for many reasons, not least of which is that it has essentially eliminated the Medieval Warm Period of the 11th to 14th centuries and the Little Ice age of the 17th to 19th centuries.
James Hansen - "By failing to take action against global warming, the federal government has violated its legal obligation to protect the atmosphere as a resource that belongs to everyone."
"Five of the plaintiffs are teenagers, who have a "profound interest in ensuring our climate remains stable enough to ensure their right to a livable future." Does the "right" of these few teenagers in the First World take preference over the "rights" of billions of children, teenagers and parents in the Second and Third Worlds to plentiful energy from fossil fuels? These teenagers, their parents and grandparents have benefited tremendously from their ample use of fossil fuels for the last century and more. Is the science "settled" and the scientific community certain that continued use of fossil fuels is going to bring life on Earth to its knees? Should nuclear energy be supported by insisting that billions of people forego the use of fossil fuels and resort to cooking and heating fires from brush, twigs and dried dung?
James Hansen - We conclude that Earth in the warmest interglacial periods was less than 1°C warmer than in the Holocene and that goals of limiting human-made warming to 2°C and CO2 to 450 ppm are prescriptions for disaster.
Rapid reduction of fossil fuel emissions is required for humanity to succeed in preserving a planet resembling the one on which civilization developed.
Milton Caplan - Following the fourth anniversary of the Fukushima accident, it is good to see there is less emphasis on the nuclear accident and more discussion of the significant natural disaster – the tsunami and earthquake that killed some 20,000 and destroyed so much, leaving 300,000 homeless. It is now clear that the nuclear accident will not be a cause for radiation-induced cancer, food is not contaminated, and most people can return to their homes should they so desire.
On the other hand, in Germany a decision to shut down some nuclear units in 2011 immediately following the Fukushima accident and to close the rest by 2022 has led to a large new build construction program of lignite-fired units to meet short term energy needs. With several under construction and some now in operation, coal is producing about half of Germany’s electricity.
To say that the Earth is a human planet becomes truer every day. Humans are made from the Earth, and the Earth is remade by human hands. Many earth scientists express this by stating that the Earth has entered a new geological epoch: the Anthropocene, the Age of Humans.
As scholars, scientists, campaigners, and citizens, we write with the conviction that knowledge and technology, applied with wisdom, might allow for a good, or even great, Anthropocene. A good Anthropocene demands that humans use their growing social, economic, and technological powers to make life better for people, stabilize the climate, and protect the natural world.

British Geological Survey. During the last ice age, lots of sea water was stored in ice sheets and glaciers and sea level was, on average, more than 130 metres lower than it is today.
Shrinking Ice, Rising Seas. Sea level rise is an indicator that our planet is warming. When ice on land, such as mountain glaciers or the ice sheets of Greenland or Antarctica, melts, that water contributes to sea level rise
Whatever the cause of sea level change may be in the future, there is nothing mankind can do to control it. He must "go with the flow" and move to higher ground, if the level is rising. No king or president can protect people living close to sea level when it is rising. In the past, civilizations responded wisely. Will people today expect their government to protect them and their property from rising seas?
Stewart Brand On Why Environmentalists Should Embrace Nuclear Power. Considering all the alternatives, including wind and solar, environmentalists must come to terms with the reality that nuclear power is the greenest, safest, most reliable answer to our energy challenges. That is the message from leading environmentalist, counter-cultural icon, and once-opponent of nuclear power Stewart Brand in a new video interview posted by Big Think.

The framing of the climate change problem by the UNFCCC/IPCC and the early articulation of a preferred policy option has marginalized research on broader issues surrounding climate variability and change and stifled the development of a broader range of policy options. The wickedness of the climate change problem provides much scope for disagreement among reasonable and intelligent people. Arguably the biggest problem with climate policy has been an overly narrow set of narratives and policy options.
