Global Warming
gregladen | October 29, 2015A week or so ago, I got a couple of emails and tweets about a blog post on Medium.com, an internet thing of which I had never heard. Apparently Medium.com is a big giant blog that anybody can go and blog their big giant thoughts on: like tumblr, but more bloggy.
Anyway, some dude by the name of David Siegel, Web Page Designer, posted a really long blog post about climate change on medium.com.
Have you ever been poking around on the Intertoobs, when somebody comes along and says, "Hey, I never really thought about global warming/vaccination/evolution before, but suddenly and unexplainably I am…
gregladen | October 22, 2015We're gonna need a bigger boat. Well, actually we're gonna need a bigger y-Axis. This has been happening for a while.
NOAA has just published September's global surface temperature, which turns out to be 0.90C above their baseline (20th century average). According to NOAA, this is the highest value for September on record, 0.19C higher than last year, which was also a record. The graph above shows the year to date average, though September, for NOAA's entire data set.
Ed Hawkins, a climate scientist at the University of Reading, recently tweeted a graph he produced to show global surface…
gregladen | October 21, 2015The University of Texas Energy Poll tracks Americans' opinions on energy and climate change related issues. You can see the results of the latest iteration of the poll here.
Opinions are changing.
Respondents are stressing less about energy prices and instead are worried more about environmental costs. Almost half are willing to pay higher prices to protect the environment — nine points higher than in the last poll. Thirty-four percent are unwilling.
Most striking are their attitudes on global climate change. It’s occurring, say 76 percent — a surge of 6 points in six months and 11 points…
gregladen | October 19, 2015A few days ago, NASA released it's GISS TEMP global surface temperature data showing that in that data set September was warm, with the same value as August (which was also warm). At least one science denier has told me that the fact that August and September were the same means that global warming was not real. What an idiot.
Anyway, it does depend on what data set you look at. If you look at ALL the data sets together on the same graph and stand back even a short distance you will see that they are all about the same. Global warming is real no matter how you measure it. But when we look at…
gregladen | October 12, 2015The NASA GISS global surface measurement for September is out. I don't know off hand if there are corrections for earlier months. The data for September show the month as the same as the earlier month, 0.81 degrees C anomaly.
The current best estimate of the warming of the Earth's surface from anthropogenic global warming, using the NASA data and a 12 month running mean, looks like this:
Looking at just the first months of the year (for each year) to estimate the position of the present year as a record breaker (or not) we get this:
Word on the street is that the present month, October,…
gregladen | October 9, 2015South Carolina Floods
I haven't said much about this partly because there is so much good coverage, but South Carolina's floods, still ongoing, are going to get on the list of worst weather events of 2015. Since these floods are amounting to a one in 1,000 year event, they are actually on the list of worst weather events since Vladimir the Great died, Cnut the Great invaded Enlgand (unrelated event), Eric Haakonsson outlaws berzerkers in Norway, and Olaf Haraldson declared himself King of Norway.
And yes, that event was climate change enhanced in at least two ways, maybe three. With global…
gregladen | October 8, 2015This just out from NOAA:
As record ocean temperatures cause widespread coral bleaching across Hawaii, NOAA scientists confirm the same stressful conditions are expanding to the Caribbean and may last into the new year, prompting the declaration of the third global coral bleaching event ever on record.
Waters are warming in the Caribbean, threatening coral in Puerto Rico and the U.S. Virgin Islands, NOAA scientists said. Coral bleaching began in the Florida Keys and South Florida in August, but now scientists expect bleaching conditions there to diminish.
“The coral bleaching and disease,…
gregladen | October 5, 2015Every year the sea ice that covers the northern part of the Earth expands and contracts though the winter and the summer. The minimum extent of the sea ice is usually reached some time in September, after which it starts to reform.
Human caused greenhouse gas pollution has increased the surface temperatures of the earth, as measured on the land at about heat height with thermometers, and on the sea at the surface, mainly with satellites. Warming of the surface has continued apace for several decades, though with some expected squiggling up and down in how fast that is happening.
Greenhouse…
gregladen | September 26, 2015There is no doubt that Associated Press’s Seth Borenstein is a top notch science reporter. However, he is a professional journalist, and for this reason I expect him to be part of, and to be guided by, the culture of journalism. The culture of journalism involves a critical feature that makes journalism work: When researching and reporting a story, seek the other perspectives, those that for one reason or another come to a different conclusion than the perspective that may have initially gotten one’s attention. The Pope speaks to the Joint Session of Congress, and the most obvious thing we…
gregladen | September 24, 2015Scientists in all disciplines agree with climate scientists that global warming is real and caused by humans.
The vast majority of climate scientists, very close to 100%, understand that the phenomenon known as “global warming” (warming of the upper 2,000 meters of the ocean, the sea surface, and that atmosphere at the surface of the land) is happening, and is caused by human greenhouse gas pollution. (eg. Anderegg W R L, Prall J W, Harold J and Schneider S H 2010 Expert credibility in climate change Proc. Natl Acad. Sci. USA 107 12107–9) Unsurprisingly, the vast majority, very close to 100…
gregladen | September 23, 2015The Associated Press has changed the AP Stylebook, tossing out a commonly used set of terms in favor of an entirely inappropriate word, for describing those who incorrectly and without foundation claim that climate change science is a hoax, or wrong, or misguided, or otherwise bogus.
The term "skeptic" has a long history, but has come to refer to those who regard claims, usually about nature, health, or anything where science may inform, with studied incredulity. The skeptic wants evidence, and they are organized. The Skeptics Society has a magazine, and the magazine has a podcast. The…
gregladen | September 22, 2015Look at the graph at the top of the post.
This is a graph from the now famous Exxon documents that date to 1981, explaining how Exxon scientists were projecting global warming with continued release of the greenhouse gas CO2 into the atmosphere. There is a lot written about that work which remained secret until just a few days ago. The timing of this expose is interesting because it comes at about the same moment as a call to use US RICO laws to investigate and possibly prosecute those who seem to have been conspiring for a long time muddy the waters about the science of climate change in…
gregladen | September 19, 2015The following is the text of a letter written by a number of scientists asking for a federal investigation of climate science denial under the RICO statute.
Letter to President Obama, Attorney General Lynch, and OSTP Director Holdren
September 1, 2015
Dear President Obama, Attorney General Lynch, and OSTP Director Holdren,
As you know, an overwhelming majority of climate scientists are convinced about the potentially serious adverse effects of human-induced climate change on human health, agriculture, and biodiversity. We applaud your efforts to regulate emissions and the other steps you are…
gregladen | September 18, 2015We drove north for two days, to arrive at a place that existed almost entirely for one reason: To facilitate the capture and, often, consumption of wild fish. The folks who run the facility make a living providing shelter, food, boats, fishing tackle, easy access to a fishing license, and they can be hired as guides. The whole point is to locate, capture, butcher, cook, and eat the fish. The fish themselves have little say in the matter.
And while talking to the people there we got a lot of advice as to how to find and capture the fish, and offers were made to assist with the butchering and…
gregladen | September 15, 2015A few items for you.
California drought: Sierra Nevada snowpack falls to 500-year low
The Sierra Nevada snowpack that is a critical water source for California fell to a 500-year low last winter – far worse than scientists had estimated and underlining the severity of the current drought, according to new research.
The snow accumulation in the mountains was just 5% of what is normal, inflating the risk of wildfires, drying up wells and orchards, and pushing communities into water rationing.
Climate Central has a couple of interesting US maps showing trends in change over time in Fall…
gregladen | September 15, 2015Climate Change: Discover How It Impacts Spaceship Earth (Build It Yourself) covers many concepts in earth science, from paleontology to climate systems to how to make a battery out of apple (how can a kid's science activity not include the apple battery!). This book represents an interesting concept, because it involves kids in mostly easy to do at home projects, covers numerous scientific concepts, and takes the importance of global climate change as a given. There is a good amount of history of research, though the book does not cover a lot of the most current scientists and their key work…
gregladen | September 14, 2015California voters feel increasingly squeezed by their drought, according to a new USC Donrslife/Los Angeles Times poll.
September 11, 2015 — As one of California’s most severe droughts on record continues to worsen, more than one in three state voters say the drought has had a major impact on them and the lives of their families, according to results from the latest USC Dornsife College of Letters, Arts and Sciences/Los Angeles Times Poll.
Thirty-five percent of California voters said the drought has had a major impact, 50 percent said it has had a minor impact, and 14 percent said it has…
gregladen | September 14, 2015According to the Japan Meteorological Agency, "The monthly anomaly of the global average surface temperature in August 2015 (i.e. the average of the near-surface air temperature over land and the SST) was +0.45°C above the 1981-2010 average (+0.79°C above the 20th century average), and was the warmest since 1891. On a longer time scale, global average surface temperatures have risen at a rate of about 0.65°C per century."

gregladen | September 13, 2015September is when the melt of the Arctic Sea Ice stops, and the re-freeze starts. We are probably not at the minimum yet, but the amount of melting is starting to level off so we can see where we are. The above graphic, made here (go and play with the interactive graph) shows the first ten years of ice freezing and remelting in the data set to use as a baseline for comparison, and the present year. Yes, there is much less sea ice on the northern end of the planet than usual.
This version of the graph shows the years with less ice, so far, than the present year. This includes the famous 2012…
