6:17 PM | Skills needed for a successful PhD
My department is busy revising the set of milestones our PhD students need to meet in the course of their studies. The milestones are intended to ensure each student is making steady progress, and to identify (early!) any problems. At the moment they don’t really do this well, in part because the faculty all seem […]

9:57 PM | Roughan’s relaxed, world drowns
Insouciance is the new face of climate change denial. John Roughan’s column in Saturday’s New Zealand Herald was a typical example. Half a metre sea level rise by the end of the century? What’s there to be concerned about in that, he scoffs. A bach at the water’s edge might no longer be a good […]

7:07 AM | Weather extremes take twin crop and disease toll
Extreme rain has boosted harvests and droughts have harmed them, but both are linked to outbreaks of deadly viruses show NASA's Assaf Anyamba and his colleagues.

6:13 AM | The climate change uncertainty monster – more uncertainty means more urgency to tackle global warming
A new two-part study published in Climatic Change by a team of scientists led by Stephan Lewandowsky examines mathematically what happens to the risks posed by climate change when the scientific uncertainty increases. Part 1 of the study explores two important points. First, the probable range of climate sensitivity to the increased greenhouse effect isn't symmetrical. Instead, based on the available evidence and research, it's more likely that we'll see a large amount of global warming than a […]

9:08 AM | Citizen science: how can we all contribute to the climate discussion?
Until the turn of the 20th century, science was an activity practiced by amateur naturalists and philosophers with enough money and time on their hands to devote their lives to the pursuit of knowledge and the understanding of the natural world. Today, scientific research is an industry of its own, carried out by highly trained […]

The second part of the new IPCC Report has been approved – as usual after lengthy debates – by government delegations in Yokohama (Japan) and is now public. Perhaps the biggest news is this: the situation is no less serious than it was at the time of the previous report 2007. Nonetheless there is progress […]

5:42 AM | Earth has a fever, but the heat is sloshing into the oceans
Much has been made about the Earth's energy imbalance (extra energy absorbed by the Earth). It is clear the Earth is out of balance, in laypersons' terms, it has a "fever". What isn't clear is how bad the fever is. A new study by Dr. Matt Palmer and Dr. Doug McNeall moves us closer to answering this "fever" question.   Matt Palmer and Doug McNeall These scientists used data from the latest group of climate computer models (CMIP5) to look at the relationships between the energy flows at […]

6:52 PM | O Best Beloved: Just-so stories in ecology and evolution
Sloth-moth symbiosis. Dinosaur-devestating asteroid impacts. Girl’s preference for pink. Are these fact, or fiction? It turns out that often what we think we know about the world is more based on story-telling than the byproduct of the scientific method. In science, calling something a ”just-so story” is almost universally a criticism. The term is a direct reference […]
3:22 PM | Snowy Owl Irruption
Laura Nielsen for Frontier Scientists – This winter snowy owls were on the move; unusually large numbers of the magnificent birds made their way to the Lower 48 United States. With a wing span greater than four feet and distinctive plumage, snowy owls are a glorious sight. The birds' winter migrations normally take them to Canada's southern provinces. Some birds come all the way to the northern U.S. – especially near the coasts. Yet this year snowy owls winged their... Read more

New Zealand political reaction to the IPCC’s WG2 report has divided along expected lines: the Green Party and Labour used the findings to call for more action, the National-led government “welcomed” the report but said it is already doing enough, while the fringe right wing ACT party issued a press release making the abolition of […]

6:00 AM | IPCC report warns of future climate change risks, but is spun by contrarians
The Intergovernmental Panel on Climate Change has just published its latest Working Group II report detailing impacts, adaptation, and vulnerability associated with climate change. The picture it paints with respect to the consequences of continued climate change is rather bleak. For example, the report discusses the risk associated with food insecurity due to more intense droughts, floods, and heat waves in a warmer world, especially for poorer countries. This contradicts the claims of climate […]

Nigel Lawson, not a scientist, but confuses public about science helped by the BBC.David Rose wrote in The Daily Mail that Mr MacLeod, head of editorial standards and compliance for BBC Scotland, sent an email to his colleagues: "When covering climate change stories, we should not run debates / discussions directly between scientists and sceptics. If a programme does run such a discussion, it will... be in breach of the editorial guidelines on impartiality."Anthony Watts wrote a response in his […]

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 […]

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 […]

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 […]
