Here is some good news from the Caribbean – despite a >95% decline in staghorn coral since the 1970′s, there are some signs of resurgence:
Dropping 12 feet below the ocean’s surface less than a mile off Fort Lauderdale’s beach-front towers, a diver might wonder if he or she somehow got magically transported to [...]
Recently we have been getting a bunch of comments on Climate Shifts that i’ve decided not to ‘approve’ after being held for moderation – these have either been obvious ‘sock puppets’ or comments that fail to justify their own existence. Climate Shifts is an open forum: have your say. If you don’t agree with what we post, tell us! If you have any ideas, comments or critique, comment on the blog or feel free to drop us an email at climateshifts@gmail.com
Back at the start of the decade, Coral List (a list-serv email discussion run by NOAA) had some great topics up for debate amongst the coral reef scientific community. These days Coral List continues to make for a fantastic place for information and discussion, yet the intense debate [...]
“This is not a political debate, it’s gone way beyond simply debating the science of whether or not we should act”
Click on the link below to see Ove on the Australian television program ABC Catalyst discussing global climate change and the onset of mass coral bleaching in the late 90′s.
A recent report by the Institute of Mechanical Engineers (IMECHE) suggests some pretty interesting approaches to geo-engineering carbon reducing structures, including artificial trees, algae-coated and reflective buildings. See above for the artificial tree idea, which according to the ABC News are envisioned to be 12 metres tall, and absorb enough [...]
“Now that it looks as if some sort of agreement may come out of Copenhagen, its natural to ask what sort of agreement we need. The current targets being proposed suggest that warming should be limited to 2 degrees over the next century. That implies stabilising atmospheric C2 concentrations at 450 ppm, and an agreement [...]
A new report/analysis of three methods of climate-engineering is available online from Copenhagen Consensus Center.
Climate engineering could offer an extremely cheap, fast solution to climate change, according to this comprehensive analysis of its costs and benefits.
An Analysis of Climate Engineering as a Response to Climate Change by Dr. [...]
The news is in – according the the National Climatic Data Center, this July has been the hottest in the last 130 years of record keeping:
The heat is most noticeable near the Arctic, where water temperatures are as much as 10 degrees above average. The tongues of warm water could help [...]
A positive feedback is define as “processes that amplify climate change”, such as reduced absorption of CO2 by the oceans and the ice-albedo effect. As time goes on, scientists are finding more and more of these positive feedback mechanisms, further increasing the warming effect. One of the long [...]
I guess this is what people expect when you tell them “I’m a marine biologist”. These incredible images of humpback whales were taken by underwater photographer Marco Queral in the south Pacific Ocean.
‘Their enormous size itself must be considered as an immediate life-threatening danger.
‘I must be very cautious when they [...]
