2:53 PM | Climate change solution? UN touts ambitious (but cheap) investment in renewable energy
The world is warming rapidly due to greenhouse gas emissions, threatening everything from our food supply to our ecosystems, but the solution may be surprisingly cheap, according to the third and final report from the Intergovernmental Panel on Climate Change (IPCC). The report recommends a rapid and aggressive switch from fossil fuel-based energy to renewables.

11:01 AM | IPCC WG3: it does not cost the world to save the planet
The IPCC has just released the summary for policymakers of the Working Group 3 report on mitigating climate change. It makes clear that the world has to act quickly to restrict carbon emissions to have a reasonable chance of restricting warming to 2ºC by the end of the century, but establishes that the costs of […]

9:59 AM | Detailed regional data reduce warming-drought link doubts
In Portugal and Spain climate change has already driven over 2°C of warming in summer, and new findings from Sergio Vicente-Serrano from the Pyrenean Institute of Ecology are dispelling uncertainties that the temperatures are making drought more severe and widespread.

Vicente-Serrano, S., Lopez-Moreno, J., Beguería, S., Lorenzo-Lacruz, J., Sanchez-Lorenzo, A., García-Ruiz, J., Azorin-Molina, C., Morán-Tejeda, E., Revuelto, J., Trigo, R. & Coelho, F. (2014). Evidence of increasing drought severity caused by temperature rise in southern Europe, Environmental Research Letters, 9 (4) 44001. DOI:

3:10 PM | What a batting average!
.280, a respectable, although not great major league baseball batting average. Oh, but this isn't about baseball, it's about accurate reporting of climate science news on PHLOX News.  Yes, that's right, good old PHLOX News is presenting inaccurate information about climate news over 70% of the time, and just like in baseball that's how many times you strike out.  So, if you're a PHLOX News fan, a regular listener who relies on the PHLOX network for information, then you probably […]

12:21 AM | Life at 400ppm: catching up with a Pliocene atmosphere
With global atmospheric carbon dioxide bumping along just under 400ppm, and sure to break through to higher levels in the near future, it’s worth taking a long hard look at what the climate system was like the last time CO2 was at these levels — the Pliocene period 3-5 million years ago. Professor Maureen Raymo […]

1:24 PM | Earth Institute Scientists Speak Out on Climate Change
In the light of recent varied efforts to focus public attention on the risks of climate change, we asked Earth Institute scientists what they want the public to understand about the issue and how they see their roles.

11:28 PM | TDB Today: Ragged right caught in reality’s shit sandwich
This week’s Daily Blog post takes a further look at NZ political responses to the release of the of the second part of the IPCC’s Fifth Report, and ponders how everyone who has gleefully claimed that adaptation is all we need to do will react when the third report — on mitigating carbon emissions — […]

7:31 PM | Policy?
ATTP has a post discussing Mapping the sceptical blogosphere (which I’m sure I read (the paper, I mean) and had the same reastion: “whaat? You mean they’re taking these jokers seriously?” But I don’t seem to have written it down anywhere). Anyway, ATTP then asks, of the septics: So, why do these sites focus on…

12:25 PM | Shindell: On constraining the Transient Climate Response
Guest commentary from Drew Shindell There has been a lot of discussion of my recent paper in Nature Climate Change . That study addressed a puzzle, namely that recent studies using the observed changes in Earth’s surface temperature suggested climate sensitivity is likely towards the lower end of the estimated range. However, studies evaluating model […]

10:19 PM | Climate Change: a Matter of Public Health
People have tried to cast climate change as an environmental issue, a social justice issue and a development issue. Madeleine Thomson of the International Research Institute for Climate and Society argues climate change can be understood much better if we consider it an issue of global public health.

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 […]

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.

8:41 AM | Impacts of Climate Change – Part 2 of the new IPCC Report has been approved
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 […]

11:59 AM | A Climate Mob
In the mid-2000s, I was researching an archaeology story that took me to several national parks in the Southwest. At one of them, the National Park Service (NPS) archaeologist discussed competing theories about the disappearance of a mysterious ancient culture. For decades, there had been heated debate among scholars over what became of this culture. In an […]The post A Climate Mob appeared first on Collide-a-Scape.

9:22 PM | Le NIPCC ancien est deja arrive
I don’t appear to have mocked the NIPCC recently, preferring to consign them to oblivion, but JoNova is somewhat implausibly singing their virtues, so I’ve noticed. If you read the report you’ll see that its prefixed by recommendations from the Great and the Good; and they’ve been fortunate enough to squeeze in praise from that…

Here is an article I wrote for the April edition of the Marshwood Vale Magazine. This winter, the UK experienced an exceptional series of storms. Heavy rain combined with strong winds and high waves lead to widespread coastal flooding and coastal damage. There was significant disruption to individuals, businesses and infrastructure and many parts of … Continue reading →

9:34 AM | Climate crisis? What Crisis? NZ right ignore IPCC call for action
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 […]

My monkey, whilst faked in, is every bit as valid as their monkey. Its from the Rare Animals feed on facebook, which…

5:37 PM | Apocalypse now? Climate change already damaging agriculture, acidifying seas, and worsening extreme weather
It's not just melting glaciers and bizarrely-early Springs anymore; climate change is impacting every facet of human civilization from our ability to grow enough crops to our ability to get along with each other, according to a new 2,300-page report from the Intergovernmental Panel on Climate Change (IPCC). The massive report, from the Nobel Prize-winning body, states definitively that climate change is already affecting human societies on every continent, including decreasing agricultural […]

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.
