We sailed from Amsterdam with despatches from their High Mightinesses the States of Holland. The only circumstance which happened on our voyage worth relating was the wonderful effects of a storm, which had torn up by the roots a great number of trees of enormous bulk and height, in an island where we lay at anchor to take in wood and water; some of these trees weighed many tons, yet they were carried by the wind so amazingly high, that they appeared like the feathers of small birds floating in the air, for they were at least five miles above the earth: however, as soon as the storm subsided they all fell perpendicularly into their respective places, and took root again, except the largest, which happened, when it was blown into the air, to have a man and his wife, a very honest old couple, upon its branches, gathering cucumbers (in this part of the globe that useful vegetable grows upon trees): the weight of this couple, as the tree descended, over-balanced the trunk, and brought it down in a horizontal position: it fell upon the chief man of the island, and killed him on the spot; he had quitted his house in the storm, under an apprehension of its falling upon him, and was returning through his own garden when this fortunate accident happened. The word fortunate, here, requires some explanation. This chief was a man of a very avaricious and oppressive disposition, and though he had no family, the natives of the island were half-starved by his oppressive and infamous impositions.
The very goods which he had thus taken from them were spoiling in his stores, while the poor wretches from whom they were plundered were pining in poverty. Though the destruction of this tyrant was accidental, the people chose the cucumber-gatherers for their governors, as a mark of their gratitude for destroying, though accidentally, their late tyrant.
-- The Surprising Adventures of Baron Munchausen, by Rudolph Erich Raspe
On July 20th, James Hansen, the former NASA climatologist who brought climate change to the public's attention in the summer of 1988, issued a bombshell: He and a team of climate scientists had identified a newly important feedback mechanism off the coast of Antarctica that suggests mean sea levels could rise 10 times faster than previously predicted: 10 feet by 2065. The authors included this chilling warning: If emissions aren't cut, "We conclude that multi-meter sea-level rise would become practically unavoidable. Social disruption and economic consequences of such large sea-level rise could be devastating. It is not difficult to imagine that conflicts arising from forced migrations and economic collapse might make the planet ungovernable, threatening the fabric of civilization" . . . .
James Hansen, the dean of climate scientists, retired from NASA in 2013 to become a climate activist. But for all the gloom of the report he just put his name to, Hansen is actually somewhat hopeful. That's because he knows that climate change has a straightforward solution: End fossil-fuel use as quickly as possible. If tomorrow, the leaders of the United States and China would agree to a sufficiently strong, coordinated carbon tax that's also applied to imports, the rest of the world would have no choice but to sign up. This idea has already been pitched to Congress several times, with tepid bipartisan support. Even though a carbon tax is probably a long shot, for Hansen, even the slim possibility that bold action like this might happen is enough for him to devote the rest of his life to working to achieve it. On a conference call with reporters in July, Hansen said a potential joint U.S.-China carbon tax is more important than whatever happens at the United Nations climate talks in Paris.
One group Hansen is helping is Our Children's Trust, a legal advocacy organization that's filed a number of novel challenges on behalf of minors under the idea that climate change is a violation of intergenerational equity — children, the group argues, are lawfully entitled to inherit a healthy planet.
A separate challenge to U.S. law is being brought by a former EPA scientist arguing that carbon dioxide isn't just a pollutant (which, under the Clean Air Act, can dissipate on its own), it's also a toxic substance. In general, these substances have exceptionally long life spans in the environment, cause an unreasonable risk, and therefore require remediation. In this case, remediation may involve planting vast numbers of trees or restoring wetlands to bury excess carbon underground.
