This week the organisation known as GLOBE met in London and launched its biannual review of national climate legislation. The GLOBE Climate Legislation Study is up to its third edition and covers the ongoing efforts in 33 countries. Of these, GLOBE claims that 18 countries have made substantial progress, 14 have made limited progress and one country has been singled out for taking a backwards step.[read more]

Two Studies Now Confirm Extreme Weather Caused by Global Warming

August 13, 2012 by David Hone
24

A recent analysis shows how the distribution of summer temperatures has shifted in recent decades, to the extent that there has been a notable change in the frequency of what were extreme outlying events. This in turn led NASA to assert that “the recent bouts of extremely warm summers, including the intense heat wave afflicting the U.S. Midwest this year, very likely are the consequence of global warming”.[read more]

Are Canada's oil sands to blame for rising atmospheric CO2?

May 22, 2012 by David Hone
7

In a recent New York Times opinion piece, NASA climate scientist James Hansen again puts forward his very compelling argument for strong action on limiting global CO2 emissions. He argues that Canadian oil sands is illustrative of an ongoing global trend to extract or mine increasingly challenging reserves of oil, gas and coal and bring them to market, a behaviour that could mean "game over for the climate".[read more]

Starting to Understand Extreme Weather

April 5, 2012 by David Hone

With a new report coming from the IPCC on managing the risks associated with extreme weather and continued weather phenomena attracting media attention, it is more important to attempt to get to grips with the science and statistics behind this rapidly emerging field of research. Work along such lines is starting to develop.[read more]

What drives James Hansen on climate change

March 8, 2012 by Lou Grinzo

James Hansen, a climate scientist who certainly needs no introduction to regular readers of this site, has given a TED talk about what motivates him to activism on climate change. I beg you to find 18 consecutive distraction-free minutes to watch this video of his talk:     I wish we had many, many more people like...[read more]

Thoughts on Keystone XL

September 26, 2011 by David Lewis

James Hansen used to say he couldn't imagine a better person to head the DOE than Stephen Chu.  Both men entered political life to do something about getting civilization to respond to the evidence for climate change.   Yet the Keystone XL issue has them on opposing sides.  Hansen led those protesting the...[read more]

When Changing A Lightbulb Isn’t Enough…

September 1, 2011 by Marc Gunther

   What have you done lately about climate change? In the last two weeks, about 700 Americans – with more to come – have been arrested in front of the White House, calling on President Obama to block the construction of the $7 billion, 1700-mile Keystone pipeline project that will bring Canadian tar sands oil to largest...[read more]

NASA’s James Hansen Says Nuclear Is Safer Than Fossil

June 24, 2011 by Jonathan Smith
12

Image via Wikipedia In a Treehugger interview on Climate Change and Intergenerational Justice, NASA’s James Hansen says it is very unfortunate that “a number of nations have indicated that they’re going to phase out nuclear power… The truth is, what we should do is use the more advanced nuclear power. Even the old nuclear power is much...[read more]

Our Climate Fate On The Toss Of A Coin?

April 8, 2011 by David Hone

Perhaps in response to the initial findings of the Berkeley Earth Surface Temperature project and the reported disappointment of some climate skeptics after the lead of the project testified before a Congressional committee, the Wall Street Journal Europe published an article on April 5th by former commodity market statistician Douglas Keenan which questions the significance, in statistical terms, of the warming of the planet over the last century.[read more]

Doc alert: Paleoclimate Implications for Human-Made Climate Change

January 19, 2011 by Lou Grinzo

The Paleoclimate Implications for Human-Made Climate Change, a draft of a new paper by James E. Hansen and Makiko Sato is available [PDF]. The paper’s abstract: Milankovic climate oscillations help define climate sensitivity and assess potential human-made climate effects. We conclude that Earth in the warmest interglacial periods was...[read more]

Hansen on reticence and the threat of sea level rise

November 9, 2010 by Lou Grinzo
1

James Hansen has published a short piece, Scientific reticence and sea level rise [PDF], which I highly recommend. The abstract and some selected clips: I suggest that a ‘scientific reticence’ is inhibiting the communication of a threat of a potentially large sea level rise. Delay is dangerous because of system inertias that could create...[read more]

Watch the Climate Rally now. I’m on at 4:50 EDT.

April 25, 2010 by Joseph Romm

The “largest climate rally ever” is taking place on DC mall right now.  You can watch the live stream of everyone from James Hansen to James Cameron, from Sting to me, right here: I’m supposed to be on around 4:50 pm for 3 minutes, though severe weather could obviously change that. If someone can find a full schedule,...[read more]

Denis Hayes explains why you should come to the “largest climate rally ever” on the DC Mall April 25 - Come hear everyone from James Hansen to James Cameron, from Sting to me. Let's show the Tea Partiers what a real crowd looks like.

April 19, 2010 by Joseph Romm

Earth Day Network is organizing a huge event on the Mall in Washington DC on April 25. The goal is to demand tough, effective climate legislation and a swift transition away from 19th century energy sources. “So what?” you may be asking yourself. There have been a lot of climate rallies over the last 25 years and Congress still hasn’t...[read more]

Hansen calls climate change “predominant moral issue of the 21st century,” slams Congress, Cantwell-Collins

April 7, 2010 by Joseph Romm

The country’s top climatologist, NASA’s James Hansen, writes in HuffPost: The predominant moral issue of the 21st century, almost surely, will be climate change, comparable to Nazism faced by Churchill in the 20th century and slavery faced by Lincoln in the 19th century. Our fossil fuel addiction, if unabated, threatens our children...[read more]

Globally warned – review of Hamilton and Hansen

March 28, 2010 by Barry Brook

Tony Kevin, author of Crunch Time (refer to this BNC guest post), recently published a review of two climate-change-related books in The Age newspaper (Melbourne’s daily broadsheet). Unfortunately, the review only made the print edition — there is no permanent online record. As such, Tony asked me if I would reproduce them here on BNC,...[read more]
