A final thought on 2016 Australian warming : Comments

By Don Aitkin, published 14/3/2017

So any ‘average’ for Australia ignores two different and consistent temperature patterns.

Quote from Tim Ferguson, on Julia Zemiro’s Home Delivery … “Science is science unless you are a right wing ding bat”

James Hanson disputes what you suggest.

http://app.box.com/s/t050csk2z20iqk9u14vnllz3i15dh5i0

In a section titled “2.2.  Temperature during current and prior interglacial periods”, Hanson et al provide a number of references to paleoclimate studies.

https://www.theguardian.com/environment/2016/oct/03/global-temperature-climate-change-highest-115000-years

Quote:

“The global temperature has increased to a level not seen for 115,000 years, requiring daunting technological advances that will cost the coming generations hundreds of trillions of dollars, according to the scientist widely credited with bringing climate change to the public’s attention.”

Corals in N Atlantic:

http://www.sciencedaily.com/releases/2016/11/161122122811.htm

“North Atlantic coral populations -- key to supporting a variety of sea life -- are under threat from climate change, a study suggests.
Changes to winter weather conditions could threaten the long-term survival of coral in the region, upsetting fragile ecosystems that support an array of marine species, researchers say.”

Inter Glacials:

http://www.eenews.net/stories/1060051765 millions years

Scientists state that the Barnes Ice Cap on Baffin Island which has survived for a couple of million years through Inter glacials appears as though it could disappear ( March 2017). That is, temperature conditions have not been similar to what are currently being experienced.

Quote:

“The current rate of warming in the Arctic is unprecedented in the last 2.5 million years, a new study has found.
Global warming is causing significant melting throughout the region and will claim the last remnants of a massive ice sheet that once covered all of North America and that remained stable for 2,000 years, according to findings published yesterday in Geophysical Research Letters, a journal of the American Geophysical Union. The Barnes Ice Cap, which is about the size of Delaware and is located on Baffin Island in the Canadian Arctic, is likely to disappear even if humanity curtails its combustion of fossil fuels at levels not currently expected, even under the most conservative estimations.”

ant,

I have not had time to reply but perhaps note the following link.
And I would like to know the connection to climate change (from their point of view).

Your usual diversion.

Note this is what scientists are saying.

http://www.businessinsider.com.au/heres-why-we-should-be-more-concerned-than-amazed-by-the-plankton-lighting-up-tasmanias-waterways-right-now-2015-5

"The concern is, “all over the world” never included Tasmania until 1994, when the phytoplankton were first spotted that far south. By 2004, sightings were much more common.

“The displays are a sign of climate change,” Anthony Richardson, from the CSIRO, told New Scientist earlier this week."

Further, from New Scientist hyperlink (warm water):

"Until 1994, Noctiluca had not been seen in Tasmania. But global warming has been strengthening the East Australian current, which pushes warm water south towards Tasmania. “As the Southern Ocean warms, it will be warm enough for Noctiluca to survive,” says Richardson."

"Scientists who study the algae say the microscopic organisms are thriving in new conditions brought about by climate change, and displacing the zooplankton that underpin the local food chain, threatening the entire marine ecosystem."

ant,

What diversion are you referring to?

ant/Tony thinks that any data that doesn't confirm his beliefs is a diversion.

Do you not know what diversion means?

Corals and sea temperatures were being discussed. AF Aus wanted to move onto his usual nonsensical cart before horse type comments about algae through his last reference.
He should have followed up his last reference a little further, warming water is the reason for the spread of Noctiluca, Tasmania being a good example.

On todays Science Show on RN radio, part of an interview with Professor Hughes was broadcast. Professor Hughes stated they have been closely monitoring the Great Barrier Reef, through numerous fly overs and assessing through dives. He stated that they investigated areas where there was sediment disturbance; very clearly he stated there was no more bleaching of coral in such areas, as in other spots where the coral had been pristine. The Southern part of the GBR was saved through the remnants of Cyclone Winston cooling the water.

The study of the Barnes Ice Cap (above) puts a huge dent in the denier comments about paleoclimate; very clearly the study indicated that over a period of 2.5 million years the state of the Barnes Ice Cap only showed the degree of melting a few times that is now evident.

Remember, these immutable facts are stated by scientists:

a) We need greenhouse gases in the right proportion to survive. CO2 being important in regulating the respiration rate in humans. Earth would be a sphere of ice without greenhouse gases.
b) Since the Industrial Revolution the rate of CO2 and other greenhouse gases have been increasing; for CO2, it has increased from 280 ppm to over 400 ppm currently (Mauna Loa).
c) Carbon took millions of years to be sequested; we have disposed of fossil fuels (carbon) in huge quantities in a little over a century.
