8:09 AM | Severe Tropical Cyclone Pam and Climate Change
Guest post by Kerry Emanuel In the past 16 months, two exceptionally intense tropical cyclones, Haiyan and Pam, have struck the western Pacific with devastating effect. Haiyan may have had the highest wind speeds of any tropical cyclone on record, but we will never know for sure because we do a poor job estimating the […]
5:25 AM | Fossil fuels are way more expensive than you think
A new paper published in Climatic Change estimates that when we account for the pollution costs associated with our energy sources, gasoline costs an extra $3.80 per gallon, diesel an additional $4.80 per gallon, coal a further 24 cents per kilowatt-hour, and natural gas another 11 cents per kilowatt-hour that we don’t see in our fuel or energy bills.  Levelized generation costs for new US electricity generation and environmental damages by fuel type.

5:46 AM | Climate change in the Arctic is messing with our weather
There has been a lot of attention on the influence of rapid warming of the Arctic on weather in the Northern Hemisphere mid-latitudes. Much of the work has focused on changes to the Jetstream amplitudes and association of these changes to ice loss in the Arctic.  We know that the Arctic is heating faster than the planet as a whole. Consequently, there is more energy in the Arctic which can be transmitted to the atmosphere. Much of the excess heat is transferred to the atmosphere in the […]

5:36 AM | Scientists link Arctic warming to intense summer heatwaves in the northern hemisphere
This is a re-post from Roz Pidcock at Carbon Brief The Arctic is warming up, and the impacts are being felt right across the world. A new study suggests rising temperatures there could even be contributing to longer-lasting heatwaves in the northern hemisphere, like the one Russia experienced in 2010. Published today in the journal Science, the paperis the latest in a line of research suggesting how rising temperatures in the high north could be affecting our weather patterns much […]

4:00 PM | Hiatus delays unprecedented warming rates
Current global temperatures are often discussed in terms of their unprecedented nature when compared to the last few thousand years. An interesting paper in Nature Climate Change by Steven J Smith and colleagues examines the rate of warming projected by the CMIP5 ensemble and suggests that the rate of warming is unprecedented also. However, we … Continue reading Hiatus delays unprecedented warming rates →
2:42 PM | So what did-in the dinosaurs? A murder mystery…
Scientists have assembled a slew of new forensic evidence – from high-resolution dates to microscopic fossils – to prosecute the dino-killer. Their indictment has worrying implications for us. Everyone knows that the dinosaurs were wiped out - along with about 70% of all species - by a massive asteroid slamming into Mexico, right? Well, not so fast. Like a good murder-mystery, a steady drip of evidence and some major new revelations have implicated another suspect – were they […]
9:11 AM | Climate Shock
Uncertainties attend the predictions of climate science, as the scientists themselves are careful to acknowledge. Reluctant policy makers use this uncertainty to support a “wait and see” response to climate change. Prominent American economists Gernot Wagner and Martin Weitzman in their recent book Climate Shock: The Economic Consequences of a Hotter Planet are scathing in […]

5:41 AM | Consensus and geoengineering - how to convince people about global warming
Everyone agrees that global warming has become a polarized issue. Liberals tend to view themselves as being on Team Human-Caused Global Warming is a Problem, and conservatives tend to view themselves on Team No It’s Not. Convincing people to change their beliefs and leave their cultural group is a challenge with any polarized subject. When it comes to climate change, the scientific evidence falls squarely behind the first team, and so the question becomes how we reduce the […]

11:10 PM | DomPost denier debacle: science has the last word
The Dominion Post, which blotted its editorial copybook last week by publishing a factually incorrect and highly misleading opinion piece by climate denialists, has today published a heavyweight reply by three of NZ’s top climate scientists — David Wratt, Andy Reisinger and Jim Renwick1. Headed “Human role in climate change is clear”, the article is […]

Between 5-10% of men and around 0.5% of women are affected by various forms of colour blindness.

This has been pointed out many times before, but it may be worth remembering next time you make a figure or visualisation: … Continue reading Reinventing the colour wheel →
5:28 AM | Summary of climate change impacts
This is a re-post from And Then There's Physics I commented that I’d like to understand the actual impacts of anthropogenic climate change better than I currently do. It’s one thing to understand that if we continue to increase our emissions, we’ll continue to warm, sea level will rise, polar ice will melt, and the hydrological cycle will intensify; it’s another to understand quite what impact these changes will actually have. VTG, quite rightly, pointed out […]

10:12 PM | How can the pause be both ‘false’ and caused by something?
Judith Curry asked Michael Mann: "How can the pause be both ‘false’ and caused by something?"She really did, if you do not believe me, here is the link to her blog post.I have trouble seeing a contradiction, but I have seen this meme more often among the mitigation sceptics. Questions like, how can you claim there is no hiatus when so many scientists are studying it? Let's first formulate it abstractly, then give a neutral example, before we go to the climate change case where some […]

6:54 AM | Understanding Time of Observation Bias
This is a guest post by Zeke Hausfather Global temperatures are adjusted to account for the effects of station moves, instrument changes, time of observation (TOBs) changes, and other factors (referred to as inhomogenities) that cause localized non-climatic biases in the instrumental record. While the impact of adjustments that correct for these biases are relatively small globally (and actually reduce the century-scale warming trend once oceans are included) there are […]

6:20 AM | The oceans may be lulling us into a false sense of climate security
A paper published last week in Science casts more light on oceans and how they may have contributed to a false sense of security about what we face in the future. The paper, coauthored by Byron Steinman, Michael Mann, and Sonya Miller, approached the problem in a new way that connected real-world observations with state-of-the-art climate models. What the authors find casts severe doubt on other work which had oversold the role of natural climate’s ability to […]
