At this rate Canada's emission regulations should be ready by 2025. Canada is once again delaying emissions regulations in the oil and gas sector, despite major pipeline projects that continue to put intense scrutiny on the energy industry’s environmental track record ... The regulations were first promised seven years ago, and Alberta has recently criticized... Continue Reading →

The IPCC has released a very snazzy video that summarizes the fifth assessment report.

Real Climate gives the recent methane news some proper context. The bottom line is that since methane is a short lived GHG it would take a very sudden and very massive release of methane for it to have a large effect on the climate. And that is unlikely. Methane is a short-lived gas in the... Continue Reading →

Reuters nicely summarizes the outcome of the COP19 UN climate negotiations in Warsaw, Poland. FINANCE Developed nations promised in 2009 to increase their aid to poorer countries to help them cope with climate change to $100 billion a year after 2020, from $10 billion a year in 2010-12. But in Warsaw they rejected calls to... Continue Reading →

A summary of the IPCC report in 4 minutes

Chevron, Exxon and BP among companies most responsible for climate change since dawn of industrial age, figures show The climate crisis of the 21st century has been caused largely by just 90 companies, which between them produced nearly two-thirds of the greenhouse gas emissions generated since the dawning of the industrial age, new research suggests....

This video taken at 6am on Friday 8 November as Typhoon Hayian hit Hernani in Eastern Samar shows how quickly and intensely the storm surge hit.

Michael Mann echoing Keven Trenberth's position that all weather now has a climate change component since it is occurring in an altered atmosphere (one with more GHGs, heat and water vapour amongst many other factors). But herein lies the crux—we no longer live in a world without warming. Given that 1985 was the last year... Continue Reading →

From USA TODAY: The vast majority of Americans in each of 40-plus states surveyed say global warming is real, serious and man-made, and the concerns tend to be slightly higher in coastal or drought-stricken areas, says an analysis out today. At least 75% of U.S. adults say global warming has been happening, but the Stanford... Continue Reading →

From The ongoing climate negotiations in Warsaw Poland: Canada has dropped any remaining pretences of supporting global action on climate change by urging other countries to follow Australia's example in gutting its climate plan. In a formal statement, the Canadian government said it "applauds" the move by Australia this week to repeal a carbon tax... Continue Reading →

Andy Extance has written two particularly appropriate posts on Bert Bolin the first chairman of the IPCC and an instrumental figure in getting the world to agree to negotiate a climate agreement. Hopefully the current round of climate negotiations in Warsaw will accomplish more than the typical empty rhetoric and voluntary actions that have characterized... Continue Reading →

An open letter by leading climate scientists, Ken Caldeira, Kerry Emanuel, James Hansen and Tom Wigley calling on green groups to stop opposing nuclear power: To those influencing environmental policy but opposed to nuclear power: As climate and energy scientists concerned with global climate change, we are writing to urge you to advocate the development...

Mark Jaccard hitting home the point that, while spills might be locally devastating, they pale in comparison to the consequences of unmitigated climate change. Sorry, folks, but if you care about the environment – the planet for that matter – your strategy to stop oil pipelines is futile if its only focus is oil spills... Continue Reading →

Burton Richter a Nobel Laureate in physics has an interesting idea to stop the use of coal There is no excuse for the continued use of coal to generate electricity that costs too much and is a health hazard to everyone who lives anywhere near a coal-fired power plant. About 137,000 people worked in the... Continue Reading →

(h/t Andy Skuce) Andy also highlights some key points from the video which are worth highlighting: He commends the IPCC AR5 report as being “as good as science can do”. He says the difficulties of communicating the uncertainties in climate science are far greater than for other science communication problems that he has been involved in professionally,...

I haven't seen this reported elsewhere (so perhaps I am way off base) but I think the new statement of climate sensitivity in the IPCC AR5 represents some real good news compared with the statement in AR4 Here is the statement from AR5: Climate sensitivity is likely in the range 1.5°C to 4.5°C, extremely unlikely...

Here is the IPCC message: We are as certain that humans are radically changing the planet's climate as we are that tobacco causes cancer. Peter Gleick

With the fate of the proposed Keystone XL pipeline still in the hands of U.S. President Barack Obama five years on, Prime Minister Stephen Harper told a crowd of business leaders gathered in New York that he will not take no for an answer. I suppose the next step is to make an offer Obama... Continue Reading →
