Climate change - ostriches and a train crash


"For January–October 2010, the global combined land and ocean surface temperature was 0.63°C (1.13°F) above the 20th century average of 14.1°C (57.4°F) and tied with 1998 as the warmest January–October period on record."

"Sitting here shivering at the end of the coldest late November in living memory (well, in this living memory at any rate) it's somewhat surreal to contemplate the assembled panjandrams of the climate alarmism industry sunning themselves in Cancun while delivering apocalyptic pronouncements of the doom that will befall us should a sufficiently draconian regime of carbon control be imposed upon the world."

Under the title 'Rhetoric and Reality on Climate Change' the Heresiarch kicks off a discussion on whether it would be better to give up any attempt to limit man's climate impact and just start learning to live with the consequences.
"Advocates of action to forestall global warming" are we learn in a "state of desperation". 

It's strikes a disappointingly sceptic tone, but is an interesting read - not least for stating the obvious, that politically we globally don't have our act together.  We are all on board the same train.. and we are heading full speed at the buffers.

Now the little guy at the back of the carriage has tried.. "er, excuse me, but maybe we should slow down?" (many times)..  and the train drivers union has called a meeting to discuss what to do..   And now it's too late to stop the train... we are going to crash.  And the little guy is standing on his chair shouting.  "Use the f****** brakes". 

Hitting the buffers slowly will always be better than charging at them full speed.  Learning to live with the consequences is clearly a something we need to do...  but what we have to live with depends very much on how hard we manage to brake the train. 

Full speed ahead is not the right answer...

Song birds decline

Spring starts two weeks earlier than it did 25 years ago.... but do the birds know that?

Figures from the Netherlands show big declines in song bird populations which they attribute to migratory birds missing the spring food peak for feeding their young.  ... though I'm sure there must be other factors too...

When people talk about climate change not happening they are ignoring the evidence - that nature is already changing in response to climatic variation.  And when people talk about not trying to stop change, but just adapting to the change, they ignore the fact that for many species that's not an option - at least not any time soon....

A trillion tons: The clock is ticking...

Continuing the theme of BIG numbers -  Climate Feedback has links to a new site giving an estimate of the cumulative carbon dioxide emissions over the last 250 years (now somewhere past 530 000 000 000 000 tonnes)- and predicting when this figure will exceed 1 trillion tonnes - a limit calculated to keep average temperature rises below 2 degrees.

The point of course is that we need to see radical change NOW to head off an otherwise inevitable warming of the climate.  Change here meaning global cuts in emissions of between 2.1 and 4.5% per year .    What it doesn't say - but is important to understand - is that the earlier cuts are made the more effective they will be.

What are you doing for your 4.5% cut???
