Propaganda: the science of miscommunication

This  ‘exchange of ideas’ over at John Quiggin’s blog between John, Tim Lambert and ‘Global Climate Chaos‘ was well worth a re-post…

Policy changes and paradigm shifts following Copenhagen

The United Nations  climate conference in Copenhagen (which I attended ) was an excellent initiative, with some fairly interesting insights into the gulf between science and policy making. Following the conference, we were contacted by The Guardian newspaper to participate in a poll on global warming. The results are striking – almost 90% of climate scientists ‘do not believe political efforts to restrict global warming to 2C will succeed’, and that ‘an average rise of 4-5C by the end of this century is more likely’.
The poll of those who follow …

Politics of climate change in Australia

It’s been a busy few weeks in the media. Hilary Clinton and her climate change envoy met with officials in China, Obama says that the upcoming climate bill is needed to ‘save our planet’, the ‘danger threat’ of global warming was increased, Dr Hansen took the final leap from scientist to activist, and NASA’s newly launched carbon tracking satellite came to an abrupt end as it crashed into the Pacific Ocean.
However, nothing seems to beat news from home soil. In a week where the Australian government announced the emissions trading …

James Hansen: Coal-fired power stations are death factories. Close them

The Observer, Sunday 15th February:
A year ago, I wrote to Gordon Brown asking him to place a moratorium on new coal-fired power plants in Britain. I have asked the same of Angela Merkel, Barack Obama, Kevin Rudd and other leaders. The reason is this – coal is the single greatest threat to civilisation and all life on our planet.
The climate is nearing tipping points. Changes are beginning to appear and there is a potential for explosive changes, effects that would be irreversible, if we do not rapidly slow fossil-fuel emissions …

Monaco Declaration by scientists urges ambitious, urgent plans to cut emissions drastically

155 scientists from 26 countries have issued a declaration on the severe threat posed by ocean acidification following the 2nd symposium on “The Ocean in a High-CO2 World” held on 6-9 October 2008 at the Oceanography Museum of Monaco.
The Monaco Declaration, issued on 30 January 2009, states:
Ocean acidification is accelerating and severe damages are imminent
Currently the average concentration of atmospheric CO2 is 385 parts per million (ppm) [and increasing] At that 560-ppm level, it is expected that coral calcification rates would decline by about one-third. Yet even before that happens, …

CO2 non-science journalism is not doing the World a favour

Remember the last time you tried to reason with someone who constantly took your words out of context in an attempt to argue an opposite futile point? If that left you smiling politely while shaking your head, you probably felt like me after reading the article “Coral Reefs and Climate Change: Unproved Assumptions” by the Idso family posted on their website “CO2 Science” at the Center for the Study of Carbon Dioxide and Global Change. The article is another sad addition to their more than 500 un-reviewed pieces – all …

Emissions pathway to return global warming beneath 1 degree Celsius

Leading climate scientist Bill Hare has published the first emissions pathway to date that brings expected global warming beneath 1°C, albeit after peaking beneath 2°C and on the scale of centuries.
This is an immensely significant research topic for coral reefs as a rise in mean global temperature of 1°C appears to be the highest target that should be set if coral reefs are to be protected from serious degradation (see previous Climate Shifts post here).
Figure 2-1 depicts the global emissions pathway that Hare (2009: 25) suggests “is plausible technically” and …

More good legislative news from the US

There is quite of bit of federal legislative action happening in the US that bodes well for marine conservation and coral reefs.   Rick MacPherson has a nice roundup at his always excellent Maleria, Bedbugs, Sea lice and Sunsets blog.
Also check out the Saipan Blog, for a great first hand account of how a small band of marine conservationist pulled off the conservation victory of the decade.  (also thanks to Rick)

Bush establishes three massive marine parks

President George Bush has made good on his commitment to protect large areas of the Pacific from fishing:
WASHINGTON — Parts of three remote and uninhabited Pacific island chains are being set aside by President George W. Bush as national monuments to protect them from oil and gas extraction and commercial fishing in what will be the largest marine conservation effort in history.
The three areas -totaling some 195,274 square miles – include the Mariana Trench and the waters and corals surrounding three uninhabited islands in the Northern Mariana Islands, Rose Atoll …

Nasa climate expert makes personal appeal to Obama

The Guardian, 2nd January 2008
One of the world’s top climate scientists has written a personal new year appeal to Barack and Michelle Obama, warning of the “profound disconnect” between public policy on climate change and the magnitude of the problem.
With less than three weeks to go until Obama’s inauguration, Professor James Hansen, who heads Nasa’s Goddard Institute for Space Studies, asked the recently appointed White House science adviser Professor John Holdren to pass the missive directly to the president-elect.
In it, he praises Obama’s campaign rhetoric about “a planet in peril”, …

Marine ecologist Jane Lubchenco to head NOAA

As if having Barack Obama win the US election wasn’t enough good news, we just learned that he has named Dr. Jane Lubchenco as the new head of the US National Oceanic and Atmospheric Administration!  This is really incredibly good news.
The fact that the new president, and as they say “world’s most powerful person”, even knows a marine ecologist is rather amazing.
Jane has been an international leader in marine conservation for several decades.  She is probably the most visible advocate of Marine Protected Areas.  Her initial fame came from her …

Australia aims for destruction of Great Barrier Reef

The Australian Government has set a 2020 target of reducing direct national greenhouse gas emissions by between 5 to 15% and thereby aiming at a global scenario that would stabilise global atmospheric greenhouse gases at around 510 to 550 parts per million carbon dioxide equivalents (ppm CO2-e) by the end of the century.
Heogh-Guldberg et al (2007) illustrated what these targets mean for the Great Barrier Reef and much of the marine ecosystem in the following series of pictures. Picture A on the left represents current conditions for corals across much …

The oceans’ acid test: can our reefs be saved? – a note from Frontiers in Ecology and the Environment

The journal Frontiers in Ecology and the Environment have published an interesting guest editorial article titled “The oceans’ acid test: can our reefs be saved?” by Jacqueline Savitz and Ellycia Harrould-Kolieb:
The climate change dialogue has picked up steam in recent months, but it has largely ignored the oceans, in spite of the tremendous service they provide, by absorbing millions of tons of atmospheric CO2 to buffer climate change. Frontiers and other journals have highlighted the impacts of the resulting ocean acidification, but its consequences demand a lot more attention – …

Obama’s win refreshes key climate talks – Nature Special Report

Nature News, 27th November 2008
The United Nations Climate Change Conference that begins in Poznań, Poland, on 1 December will in some ways mark the end of an era. The United States’ long-standing opposition to climate regulation is vanishing, offering new opportunities for cooperation with its allies in Europe and beyond.
But to some extent, international climate negotiators will remain in limbo until 20 January 2009, when US President-elect Barack Obama enters the White House. Obama has advocated forceful domestic action on global warming and re-engagement with the international community.
“There is a …

Advice for Obama: improving the management of ocean ecosystems

Now that he won the election, everyone has advice for Barack Obama on how he should govern and what policies he should support and focus on.  Given the importance of ocean ecosystems and coral reefs, shouldn’t we get into the act?  In fact, several individuals and organizations are drafting advice on environmental policy, pressing environmental issues, etc.  Dr. Steve Carpenter (a prominent limnologist at the University of Wisconsin, Madison, USA), recently posted his advice for Obama on the Ecolog lister server (an international discussion board for ecologists).  Ill insert his letter to …
