Berkeley Earth Project
The Berkeley Earth Project is a very ambitious attempt to accurately assess the state of “Global Warming” in a very systematic and scientific way, free from the many biases, politics, and advocacy challenges that have arguably plagued the process to date. Preliminary findings are just out here a bit prematurely, as the director of the project Muller recently testified to the US Congress: http://berkeleyearth.org/Resources/Muller_Testimony_31_March_2011
Note that the results here are based on 2% sample they are using to validate their methods before they apply that method to the entire set of some 1.6 billion temperature records, a project that they maintain (and I agree) will result in the best measure to date of global temperature change.
Not surprisingly the 2% looks a lot like the temperature record we see from the major measurers of such things – CRU in England and NASA in the USA. My gut expectation about the final record is that it will reflect a slight decrease in observed warming along with a significant, though modest, increase in the “uncertainty” of such measurements. Why? That finding would be very consistent with the fact that most of the climate scientists are doing excellent work that is good and only very slightly compromised by the alarmist bent. That bent can’t change the data but I think it has inclined those – particularly in Paleodendrochronology – to view questionable assumptions by other scientists too sympathetically. Sort of a “circling of the wagons” has happened as tree ring science emerged from almost total obscurity to the single most important “climate signal” in the global warming controversies. The politics and alarmism and advocacy have very unfortunately led to some questionable interpretations and assumptions despite the obvious which are nearly rock solid findings of a global temperature rise over the last century.
Berkeley Earth is a great approach and I’m anxious to see how their transparent and hopefully unimpeachable methodology will shed light on global warming / climate change issues.
P.S. IMHO 1.there is slight global warming, 2. it’s mostly human caused, 3. it’s not going to hurt much and 4. (most importantly) YOU (and I, and even the most fervent alarmist) are almost completely unwilling to do the things needed to change our warming prospects enough that it would make more than a trivial difference in the scheme of things. If you travel much via planes or cars, keep your house between 65 and 85 degrees, fail to retrofit much of your life to save energy, etc, etc, etc then you are THE PROBLEM and you are NOT PART OF THE “SOLUTION”. Sorry, but you won’t change and many of you won’t even build nuclear power plants – part of the no-brainer solution to energy needs.
Stop calling me a climate skeptic just because I don’t believe in alarmism!
*scroll DOWN to skip to the summary*
I’m REALLY getting tired of so many friends and family calling me a global warming skeptic because 1. I am NOT a global warming skeptic and 2. It distracts from the important debate over warming which is how much it will impact our lives. There are really only two kinds of Global Warming Skeptics. The first challenge the fact that the earth, on average, has been warming up a bit. These folks are generally just stupid or stupidly adhering to the rants of people who are stupid, like Glenn Beck. The earth is, on average over the last century, warming up. Not much mind you – most estimates put the warming in the range of a degree C over the last century, but clearly the earth is warming up a bit.
There is a second kind of global warming skeptic who believes that humans are not the cause of the observed warming. FYI my misguided friends … I am NOT in that camp either! However a lot of bright folks are in that camp and are often scientifically challenging the idea that the observed warming of the last century is caused by human generated greenhouse gasses or “GHCs”. CO2 is usually cited as the main GHC culprit but there are several others like methane that are likely to play a role in observed warming. GHCs are considered the main cause of the small observed warming if, like me, you believe the warming is caused by human activity. So, I’m not THAT kind of skeptic either! Some excellent skeptical discussion of warming is at Climate Audit, the smartest of the “skeptic” blogs, and the counterpoint to Real Climate, the smartest of the blogs that discuss the science behind global warming. Several key players in the Climate Debate post at RealClimate, many are distinuished NASA scientists. I’d urge caution interpreting information from other places and even from these “very smart” blogs. The comments at all blogs tend to be much more biased (often to the point of blatant stupidity) than the posts, which even at advocacy blogs are often somewhat informative if you keep away from the personal or ego-driven junk.
Many blogs in the warming discussion take the form of advocating either for alarmism or skepticism rather than trying to review the science and the logical actions suggested by that science. I’m particularly not fond of Joe Romm’s ridiculous ”Climate Progress” which is mostly a constant attack on even well-informed skepticism and dissent from the climate alarmist “party line”. He seems to immediately ban even well reasoned dissenters from the comments, leaving … a fools pool of alarmist nonsense and political advocacy. Anthony Watts “Watts Up With That” is, IMHO, smarter and far more balanced than Climate Progress but is still pretty darn “skeptical”, tending to feature information that supports a skeptical view rather than promoting a more balanced perspective.
Summary: I AM NOT A DAMN Climate SKEPTIC! However I am not worried much about global warming. It’s impact so far has been trivial and it appears it will remain trivial, especially when we compare the likely impacts with current ongoing catastrophic conditions in much of the developing world, where water, disease, and poverty run rampant. Let’s fix that stuff first, since we can actually have an impact in that arena, and fast.
P.S. No, I have NOT changed my view about this, you just weren’t listening … See?
Climate Change Projected Impacts from IPCC 4
As the climate debates continue we see an interesting – and familiar – pattern. Even as most now claim to accept the premise that “disaster is looming”, few are willing to take the steps needed to prevent that disaster. Although in my opinion disaster is NOT looming and many climate claims are either exaggerated or unscientific nonsense, it’s certainly clear that the planet is warming and that we’re going to experience changes – mostly negative – from that warming.
The challenges we may face that are listed below are should help shape efforts to mitigate the negative changes that are coming. They also should serve as a yardstick of how much the climate alarmists are justified in their concerns about climate catastrophe. Despite many decades of “global warming alarm” we have seen very few examples of trouble so far unless you attribute to global warming things like the Australian Wildfires (cause: arson) or Hurricane Katrina (cause: nature, faulty dikes).
Mitigation of problems is likely to be a lot more productive and less costly than trying to stop the warming, which would be hard to do even if we had the resolve to do it. And of course we do NOT have the resolve to mitigate CO2 in more than very modest and largely inconsequential ways. This should be pretty darn obvious to all by now given that even those who claim they are willing to make the needed lifestyle changes to mitigate CO2 are not making those changes, such as advocating for massive nuclear power deployment, cutting personal energy use by 80% or so, etc.
So, let’s actually do something productive by addressing water shortages *NOW* when they will do a lot more good than in the future. Millions are currently in peril from human and natural catastrophic conditions in many areas – especially in the developing world. Why fret over conditions that might threaten us in 2100 when we can easily mitigate water and crop shortages RIGHT NOW. Let’s get to work people!

Global Warming – what’s to come?
Today’s report on the IPCC “Intergovernmental Panel on Climate Change” suggests that although the science is now clear, the politics are getting in the way of the credibility of the IPCC and climate science in general. Unfortunately in my view we are not debating the important items about warming, which relate not so much to the science (that proves there is warming and suggests strongly that it’s caused by humans), but relate to whether we can do anything about this and how dangerous the warming will be for humanity. In my view there is little to do now regardless of how dangerous the warming is to humanity, but it’s also unlikely the dangers are anything like they have been advertised by many in the activist community.
So I’m hoping to explore each of the following talking points in the coming months:
Climate change Impacts from NATURE CONSERVANCY:
- Impact: Higher temperatures
- Impact: Changing landscapes
- Impact: Wildlife at risk
- Impact: Rising seas
- Impact: Increased risk of drought, fire and floods
- Impact: Stronger storms and increased storm damage
- Impact: More heat-related illness and disease
- Impact: Economic losses
It should be clear to everybody that the earth has warmed a bit over the past century – most scientists believe about 0.8 degrees. It’s also *fairly* clear now that humans are almost certainly responsible for most of that warming, although there is more intelligent criticism of that idea than many believe (climateaudit.org is the best source for the “smart skeptic” POV).
But far more relevant that those two issues are the following two issues:
1. How will this affect us?
2. What can we do about warming?
…. to be continued …
Cost Benefit Analysis and the Environment
One of the most interesting topics right now is how to allocate risks and costs with respect to environmental problems like climate change. I’m having an email discussion with my good pal John and thought I’d bring some of that online for others to comment:
RE: Cost Benefit Analysis and Environment:
John’s: It is very easy to distort their definitions towards a point of view rather than towards something necessarily valid. Not that cost/benefit is never useful. It is very useful when the costs and benefits are relatively simple to define. Unfortunately costs from environmental degradation and benefits from efforts to change behavior are very difficult to delineate. In the end through the early environmental movement persistence and intelligent thinking about clean water and air prevailed over those who used cost/benefit analysis.
John Stewart on ClimateGate
This is pretty funny, especially if you know the whole scoop.
NOTE: Stewart correctly points out at the end that this does NOT debunk warming, it just “doesn’t look good”.
Climate Science Scandal – will Paleo Dendrochronology survive?
For new readers please NOTE that I am NOT a climate skeptic, I am just wondering why groupthink seems so pervasive in the climate science community, especially over at the key climate blog RealClimate .
Update: Two very thoughtful and balanced pieces written – by climate scientist Judy Curry – and by Peter Kelemen at Popular Mechanics .
Here’s the Wall Street Journal’s take on this.
Here are the infamous hacked emails.
There’s a remarkable development today on the climate front [thanks to Glenn for the link in the earlier post]. A huge amount of climate data, including some remarkable emails between scientists, have been hacked from the University of Anglia in England. These mails and data may shed some light on some of the more contentious points in climate science.
The odd methods and math seem especially conspicuous in tree ring studies of climate trends. Called Paleo Dendrochronology, these studies are VERY often used either alone or with other data in climate studies and often are used alone or with other data to make the case that global climate change is potentially catastrophic.
The best scientific work critical of global warming science seems to focus mostly on attacking this weakest link – or should I say the weakest rings – over at ClimateAudit.org.
Here is a great balanced view at UK Guardian of the story so far: http://www.guardian.co.uk/environment/2009/nov/20/climate-sceptics-hackers-leaked-emails
A critical view of the implications of this data is here at ClimateAudit
A sympathetic view is here at RealClimate where I tried to post I posted this comment and I appreciate the good sportsmanship of them letting it through moderation. When they do allow me to post this type of comment I wonder if I’ve been too hard on them for what seems like censorship, but possibly could be the crappy posting system they have over there where moderation, timestamps, and other factors seem to confuse everybody.
Somebody naively wondered why there are so few comments on this post. IMO the answer is that RealClimate is effectively content-censored to a large degree for conformance with the prevailing ideas here.
Uninformed dissenters are sometimes let in so the comment crew can bash them around, but reasoned dissenters are usually banned outright. Many don’t bother trying to post here for that very reason.
Gavin in the interest of transparency would you at least roughly estimate how many of the comments have been moderated out for this post? I would guess 95% have been zapped.
<i>[RealClimate wrote] Scientists often use the term “trick” to refer to a “a good way to deal with a problem” </i>
Could you give a few examples? I searched right here at Realclimate for uses of that term they tend to relate to “trickery”, not good science.
More climate updates: Here’s the Copenhagen Diagnosis, an excellent summary of the latest climate science since the last big IPCC report. For the record I do think this does suffer from the prevailing “somewhat alarmist” tone in some of the interpretations of the research. For example a key observation is the current pause in warming noted by satellite measures, and this is given short shrift here.
More clear thinking about climate change from Bjorn Lomborg
In the Washington Post today Bjorn Lomborg has a nice short article about why the climate conference in Copenhagen is falling short of expectations and why it’s time to start focusing on different approaches to limiting global warming.
As one of the most articulate folks working to fight the alarmism about climate change, Lomborg is often spuriously called a “climate skeptic” when in fact he has always accepted the excellent IPCC work and the obvious fact of global warming and even accepted the likelihood that most of the observed warming is caused by humans. But Lomborg rejects the many misguided, expensive approaches alarmists are suggesting to mitigate these changes.
If we are to respond effectively to global warming then we don’t need any more feel-good summits, or exaggerated but empty declarations of success from politicians. We need action that actually does good.
Yes Mr. Lomborg. But there is no climate Santa Clause, and ironically we’ll see that the inaction continues in the political arena. Hopefully innovation will trump all the inaction and hype and we’ll have some major energy breakthroughs, but I’m not going to hold my breath.
Is Climate Science on trial again?
The climate debate is entering a new state of confusion that will at least bring some of the fascinating technical issues into the popular press. The first time this happened was during the congressional hearings featuring the “Hockey Stick” debates where critics suggested that some key math and research supporting “unprecedented global warming” was seriously flawed. Although leading statisticians agreed with the critics the situation is probably best characterized as a stalemate with both sides claiming vindication and little change in the way others have addressed the issues at hand.
The technical issues sound obscure but they impact every man, woman, and child on earth in almost incalculable ways because many nations are preparing to forego a lot of GDP in the interests of climate mitigation, and this has substantial economic consequences.
I do believe in warming and believe it’s human caused. However I don’t think we can afford to do all that much about it and also don’t think the consequences are nearly as severe as advertised. Therefore I’m not reasonably called a “climate skeptic” .
Many bright people are skeptics however and everyone should resent that they are called “climate denialists”, a bizarre term used to conjure up images of the ignorance and malice of holocaust denial.
I am concerned that climate science, especially with respect to mathematical modelling and long term temperature reconstructions, has been compromised by egos and cognitive biases. I don’t think climate science has been compromised enough to reasonably suggest that human caused warming is “unlikely”, but it’s been compromised enough to suggest climate alarmists, rather than the unfairly branded “denialists”, are the ones often standing on thin ice.
Here’s a comment I tried to post at RealClimate.org but it appears to have been rejected:
It’s unfortunate to see so many insults and tired talking points rather than *key issues* such as:
Is Yamal robust?
Why does proxy selection in papers like Yamal, Kaufman seem to include more proxies with stronger GW signals than a randomized proxy selection process?
Why isn’t there a randomized proxy selection process or at least a well structured one as was suggested (but appears not implemented) in the Kaufman Arctic lakes study?
Why does it take so long to properly archive data and why is there a single shred of resistance to totally transparent archiving of source code and data?
To what degree is observed global warming the product of human activity?
To what degree is the modern warming trend unprecedented?
Role of the Medieval Warming Period and why is there so much disagreement about temps at that time? (another proxy selection issue!) Simply asserting that these questions “have been answered many times” isn’t only wrong and insulting, it’s counterproductive if you sincerely want to challenge the growing mainstream view that climate science has been compromised by cognitive biases and ego. I’m staying open to your insistence that the science has not been compromised at all and McKintyre is just a slinging mathematical mud, but posts like this don’t provide much support for that idea.
Challenging Climate Change? You WILL be BURNED at the STAKE! (after we purchase $14 in carbon credits, available online from www ….)
Although I’m very critical of alarmism in Climate Change community it’s important to understand I agree about the following:
There is a Global Warming trend.
The bad consequences of the warming will far outweigh the good ones.
Humans are very likely to have contributed to the warming , mostly via CO2 pollution.
We should work to develop CO2 reduction approaches.
[I just believe that alarmism and catastrophe claims are running rampant and I don't think there is any likely scenario that will reduce CO2 enough to make much of a difference. Non controversial studies indicate that much of the warming we are likely to see is now "baked in" to the system. I think engineering changes are more likely to work than attempts to change the behavior of people and governments that have historically done very little along the lines needed]
Now for my rant against the unconscionable attack on dissenters from the Climate alarmism “party line”:
As a fan of Paul Krugman’s usually bright and insightful economic analyses at the New York Times I was more than alarmed to read his recent post there where he suggested those who voted agains the cap and trade bill in congress were “betraying the planet” Krugman suggests in the article:
And as I watched the deniers make their arguments, I couldn’t help thinking that I was watching a form of treason — treason against the planet.
Treason against the planet? Given that treason against a mere government is often punishable by the death penalty, Krugman is very close to suggesting that the penalty for climate dissent should be …. death. To invoke “treason” against those who are presenting concerns about either the science or the alarmism running rampant now in Climate circles is both unacceptable and it is dispicable. Shame on Krugman and shame on a climate alarmism community that increasingly uses scare tactics, threats, and censorship to promote their climate change agendas.
My first reaction was to excuse Krugman’s obvious ignorance of the many legitimate challenges to alarmist climate conclusions. He appears to rely on a recent Copenhagen Climate report that clearly plays more on the politics of climate rather than the recent data points which are anything but alarming. For example Global ice remains very stable over the past decades. You’ve read about Arctic sea ice which in fact is lower (though probably no new records this year), but conspicuously the Antarctic – where the ice is increasing – is left off of the alarmist ice analyses. Surface temperatures? After 1998′s very hot temperatures we’ve seen moderation. Caveat: A pending El Nino current and pending new sunspot cycle are suggested as reasons to worry that we’ll soon see more record hot years and I think these are legitimate points. Sea Level Rise? It’s pretty consistently rising, about as much as this symbol: | Per year. Yes this matters over a long time frame but I think the folks in Florida don’t have to move quite yet. Hurricanes? You haven’t heard much in the news about them because …. there haven’t been many. Despite some silly hype, Katrina the Hurricane had little if anything to do with Global Warming (a good source is Chris Landsea, one of a handful of the world’s most knowlegeable Hurricane researchers and a former IPCC author who appears to have become fed up with the politics.) More importantly without the levey breaks Katrina would not have been all that significant and that’s mostly a human engineering issue, not a climate one. What about those big killer Australian fires? Isn’t that clearly caused by Global Warming? Well, it may have contributed to their severity but since they were lit by arsonists it seems absurd to say the climate caused them. Lastly, the models on which most dire predictions depend represent some of the most complex and non- falsifiable hypotheses in the history of science. The basics are simple and very likely (CO2 increases will increase temperatures), but the record of these climate model as predictive agents is very poor. So poor that model predictions in my view should be considered “informed speculation” more than “science”. This last point is critical. We despartely need to focus on finding climate models that predict climate correct ly, not focus on bashing dissenters who note the obvious failures of the current models.
Journalists (and apparently even some Nobel Economists like Krugman) can be excused for relying too heavily on a climate science community that has been seriously compromised by alarmism, ego problems that came from adversarial “anti science” policies under GW Bush, grant opportunism, an often incestuous peer review process, and far too many cases of statistical shenanigans. However that by no means excuses the ongoing climate witch hunt that is seeking to burn down dissenters rather than address their many legitimate concerns about how to move into our uncertain future.
Climate alarmists may be right that we are in for catastrophic changes that will ruin the planet. The data suggests otherwise. It also suggests it will be nearly impossible to significantly change the climate outcome regardless of how we act now (e.g. if CO2 emmissions stop completely today the models still project lots of warming).
However whatever the viewpoint I won’t stand by while an intellectual mob works to burn dissenters at the stake. Reason must guide our actions here – not alarmism, emotion, and vengeance.
