8:32 PM | Protected: Oxygen isotopes and lakes
There is no excerpt because this is a protected post.The post Protected: Oxygen isotopes and lakes appeared first on Climatica.
8:32 PM | Oxygen isotopes and lakes
Lakes occur across the globe and are sensitive to climatic change. Analysing the sediments that have accumulated at the bottom of lakes over time can help us to reconstruct past environmental change. Here, we focus specifically on the use of oxygen isotopes from lake sediments to reconstruct climate change (Fig.1). What are isotopes? Isotopes are variations of a particular chemical element. It is all to do with the number of neutrons. Oxygen has two main isotopes: 18O which has 10 […]

11:31 AM | Climate sensitivity wrangles don’t change the big picture on emissions
Modelling studies from Joeri Rogelj at the Swiss Federal Institute of Technology, ETH Zurich show we still need to release fewer greenhouse gases even if the world does warm more slowly in response to them than today’s best estimates suggest.

7:16 AM | Honey, I mitigated climate change
Actions of mankind release greenhouse gases into the atmosphere. Greenhouse gas concentrations have increased causing Earth to heat up, which has been evident during the last few decades. This global warming proceeds so fast that it causes problems for both the biosphere and mankind. These concerns have been largely noticed and the general attitude is that we will need to do something about the problem as soon as possible. There already are some […]
6:49 AM | Climate modelling on your PC: weather@home comes to NZ and Australia
That’s a climate model running on my iMac, thanks to BOINC, Climateprediction.net, and the new New Zealand and Australia modelling experiment launched yesterday. In this guest post, Dr Suzanne Rosier of NIWA explains what it’s all about… A new citizen science experiment in which scientists will address possible links between climate change and extreme weather […]
2:56 AM | Chinese Qihoo360, best antivirus
Computer virus are software that when executed in a given computer (affected area) perform some type of harmful activity. There is a wide range of computer virus with different definitions (malware, trojan, bugs, spyware, and more) according to the way they infect and the harm they produce. Thus, antivirus software was created in order to prevent, detect and remove computer virus. Currently we have a wide availability of different computer antivirus software, both free and with a given economic […]

11:00 AM | AABW in the news!
It only took 25 years, but my thesis topic is now becoming newsworthy!  Gluttons for punishment can see at least the abstract at A model of the formation of high-salinity shelf water on polar continental shelves.  Which is aimed at one of the important ingredients for AABW (Antarctic Bottom Water).I've been reluctant to blog about the topic because it is, after all, my baby and I'm sorely tempted to post at excruciating length and detail.  (Not that there aren't other people who […]
10:48 AM | Towards a climate risk management approach for adaptation
By Reinhard Mechler, IIASA Risk, Policy, and Vulnerability Program On March 25, member countries of the Intergovernmental Panel on Climate Change (IPCC) started discussing the key findings of the second volume of the Fifth Assessment Report (AR5) in Yokohama, Japan. The report focuses on climate-related impacts, risks and adaptation. Once approved by the 150+ governments … Continue reading →
1:40 AM | Tram Powered International Tundra Experiment
Liz O'Connell for Frontier Scientists – Multiple instruments, configured along a tram-like platform, sense the tundra below and gather detailed data while traveling along a 50 meter transect.  “We are gathering measurements that we don’t know exactly how they will be used,” said Steven Oberbauer, professor of biological sciences at Florida International University. The high resolution information is more detailed than that gained by a satellite or by a […]

In my post at The Daily Blog today — Facing the future – no Bridges too far — I take a look at the Royal Society of New Zealand’s latest information paper about the need to move New Zealand to a green economy. There’s a yawning gulf between the rational world view embodied in the […]
4:40 PM | The most common fallacy in discussing extreme weather events
Does global warming make extreme weather events worse? Here is the #1 flawed reasoning you will have seen about this question: it is the classic confusion between absence of evidence and evidence for absence of an effect of global warming on extreme weather events. Sounds complicated? It isn’t. I’ll first explain it in simple terms […]
3:05 PM | Cherry picked and misrepresented climate science undermines FiveThirtyEight brand
Nate Silver has launched a new FiveThirtyEight blog with the intent of applying his data-driven approach to a wide variety of subjects.  The problem is that Nate Silver is himself only one man, so FiveThirtyEight has hired a variety of contributors to write about the subjects that are outside his expertise and comfort zone.  For the topic of climate change, Silver decided to hire the renowned obfuscator Roger Pielke, Jr. This was immediately disappointing for those familiar […]

11:22 PM | WMO 2013 climate summary: laws of physics not negotiable, extremes to be expected on a warming planet
The World Meteorological Organisation’s (WMO) state of the climate report for 2013 was released on Sunday (pdf), and provides a very useful overview of last year’s weather and climate events. It confirms that 2013 was the 6th warmest year in the long term record (tied with 2007), that 13 of the 14 warmest years in […]
6:55 PM | Harry Bulkeley: A few questions about global warming -- Answered
An opinion writer (a retired judge) asked a few questions in his Galesburg, IL local paper, and I'll provide some answers here.  As always, I encourage you to read the original.The good judge, like the usually informative Mr. Krauthammer, starts off on a very wrong foot, with bad philosophy of science.  There are many facts in science -- the earth is round, the sun is hot, there is a greenhouse effect, and CO2 is a greenhouse gas.  All can be questioned -- but not in the trivial […]
4:12 PM | Climate Science Legal Defense Fund Needs Your Help!
Guest post by Scott Mandia. The Climate Science Legal Defense Fund (CSLDF) was launched in January 2012 by Scott Mandia and Joshua Wolfe to provide valuable legal resources to our climate scientists who are in need. CSLDF needs your help. CSLDF needs to raise $80,000. The great news is that philanthropist Charles Zeller has graciously offered to MATCH the first $40,000 that is raised and philanthropist Peter Cross has offered to put up the first $10,000. This means CSLDF already has the first […]

XKCD, the brilliant and hilarious on-line comic, attempts to answer the question How much CO2 is contained in the world’s stock of bottled fizzy drinks? How much soda would be needed to bring atmospheric CO2 back to preindustrial levels? The answer is, enough to cover the Earth with 10 layers of soda cans. However, the […]

11:03 AM | Fairness instinct trumps economic expectations on climate costs
Students taking the role of rich countries in climate negotiation games make generous offers to pay towards the cost of cutting greenhouse gas emissions on fairness grounds, finds Robert Gampfer from ETH Zurich, who suggests that governments doing the same might get popular support.

8:28 AM | The Myth Debunking One-Pager
In late 2011, I co-authored the Debunking Handbook with Stephan Lewandowsky. The purpose of the handbook was to summarise all the psychological research into misinformation and debunking into a short, concise, practical guide. We published a much more comprehensive scholarly review afterwards. Nevertheless, the much shorter version has always been the preferred option. Until, perhaps, now. I was asked recently if I could boil down the key points of the Debunking Handbook into a […]
