Posting a Diary Entry
Daily Kos welcomes blog articles from readers, known as diaries. The Intro section to a diary should be about three paragraphs long, and is required. The body section is optional, as
is the poll, which can have 1 to 15 choices. Descriptive tags are also required to help others find your diary by subject; please don't use "cute" tags.
When you're ready, scroll down below the tags and click Save & Preview. You can edit your diary after it's published by clicking Edit Diary. Polls cannot be edited once they are published.
If this is your first time creating a Diary since the Ajax upgrade, before you enter any text below, please press Ctrl-F5 and then hold down the Shift Key and press your browser's Reload button to refresh its cache with the new script files.
ATTENTION: READ THE RULES.
One diary daily maximum.
Substantive diaries only. If you don't have at least three solid, original paragraphs, you should probably post a comment in an Open Thread.
No repetitive diaries. Take a moment to ensure your topic hasn't been blogged (you can search for Stories and Diaries
that already cover this topic), though fresh original analysis is always welcome.
Use the "Body" textbox if your diary entry is longer than three paragraphs.
Any images in your posts must be hosted by an approved image hosting service (one of: imageshack.us, photobucket.com, flickr.com, smugmug.com, allyoucanupload.com, picturetrail.com, mac.com, webshots.com, editgrid.com).
Copying and pasting entire copyrighted works is prohibited. If you do quote something, keep it brief, always provide a link to the original source, and use the <blockquote> tags to clearly identify the quoted material. Violating this rule is grounds for immediate banning.
Be civil. Do not "call out" other users by name in diary titles. Do not use profanity in diary titles. Don't write diaries whose main purpose is to deliberately inflame.
The latest news from the Guardian couldn't be more dire for our hopes for regaining our balance and slowing our species' headlong stumble toward a more volatile climate. A more erratic less dependable climate pattern that could have catastrophic consequences for the functioning ecosystems our modern civilization depends on.
Hopes for 'safe' temperature increase within 2C fade as Hawaii station documents second-greatest emissions increase.

The chances of the world holding temperature rises to 2C – the level of global warming considered "safe" by scientists – appear to be fading fast with US scientists reporting the second-greatest annual rise in CO2 emissions in 2012.
Carbon dioxide levels measured at at Mauna Loa observatory in Hawaii jumped by 2.67 parts per million (ppm) in 2012 to 395ppm, said Pieter Tans, who leads the greenhouse gas measurement team for the US National Oceanic and Atmospheric Administration (NOAA). The record was an increase of 2.93ppm in 1998.
Of course the worst case scenario would be this GHG increase is showing the first indications of a feedback loop amplifying the annual increase. But it is too soon to know if that could be the underlying cause in this case. The scary fact is that once a carbon feedback loop becomes observable, it is almost certainly irreversible (in the sort term).
