climate change
gregladen | March 8, 2017It is now verified that the earliest 2017 tornados -- first tornados of the season -- struck several communities in east-central Minnesota (a few miles north and south of me). So what you say? Especially because it was a mere F1 and didn't hurt anyone!
This is an important event because the earliest recorded tornado of the year in Minnesota was previously March 18th, and that was in 1968. This tornado, striking on March 6th (confirmed yesterday by the NWS) is way earlier than that!
One tornado, near Zimmerman went for nine miles.
A second tornado appears to have passed through the…
pgleick | March 7, 2017In late February 2017, the Pontifical Academy of Sciences hosted a workshop on the human right to water organized by the Cátedra del Diálogo y la Cultura del Encuentro of Argentina with several other organizations. With many colleagues from science, law, human rights, history, and religion, this workshop offered the opportunity to debate and discuss how to integrate the human right to water with public policies in water and sanitation management globally and regionally. Two days of intense discussion culminated in a declaration by Pope Francis and a formal statement (below) signed by the Pope…
kkrisberg | February 7, 2017At the American Prospect, Justin Miller interviews Obama-era Labor Department officials on the future of worker protections under President Trump. Miller takes a behind-the-scenes peek at what it took to pass some of the Obama administration’s key labor rules, discusses the nomination of Andy Puzder to become the nation’s next labor secretary, and addresses rumors that the new administration might be gunning to abolish some Labor Department divisions entirely. Miller writes:
Not surprisingly, Obama’s top labor alums express pride in the many worker protections they were able to put in place…
gregladen | January 24, 2017From ClimateTruth.org, in response to Trump gag orders on the Environmental Protection Agency (EPA) and the United States Department of Agriculture (USDA):
“President Trump and his administration have ignored scientific reality, and now they’re trying to hide it.
“Merely five days into Donald Trump’s presidency, the administration is silencing the agencies tasked with protecting our environment, our health, and our food supply. This gag order sets a dangerous precedent and is sending a chilling message to civil servants throughout the country.
“We knew the Trump administration would go…
jdupuis | January 21, 2017While I'm working on a major update to my Documenting the Donald Trump War on Science: Pre-Inauguration Edition and preparing for the first of the post-inauguration posts, I thought I'd whet everyone's appetite with a post celebrating all the various efforts to save environmental, climate and various kinds of scientific and other data from potential loss in the Trump presidential era.
The list only includes one or two items per project. Plus I'm very likely missing some. Please let me know in the comments so I can add ones that are missing.
It's worth noting that libraries and libraries are…
pgleick | January 17, 2017National academies of sciences from around the world have published formal statements and declarations acknowledging the state of climate science, the fact that climate is changing, the compelling evidence that humans are responsible, and the need to debate and implement strategies to reduce emissions of greenhouse gases. Not a single national science academy disputes or denies the scientific consensus around human-caused climate change. A few examples of joint academy statements since 2000 on climate are listed here. Many national academies have, in addition, published their own reports and…
pgleick | January 7, 2017(Updated January 2017 by Dr. Peter Gleick, Pacific Institute)
Scientific understanding of the role of humans in influencing and altering the global climate has been evolving for over a century. That understanding is now extremely advanced, combining hundreds of years of observations of many different climatic variables, millions of years of paleoclimatic evidence of past natural climatic variations, extended application of fundamental physical, chemical, and biological processes, and the most sophisticated computer modeling ever conducted.
There is no longer any reasonable doubt that humans…
dr. dolittle | December 23, 2016New research presented at the British Ecological Society, Liverpool shows that reindeer are shrinking. These findings come from a survey conducted between 1994-2010 in Svalbard, a Norwegian island, which found the animals have lost about 12% of their body mass over this timeframe. The research team thinks the shrinking reindeer phenomenon might be caused by global warming as females have increased access to grasslands and give birth to more calves annually than in the past. This translates to less nutrients available to support each gestation causing lower birth weights and more competition…

A changing climate has the potential to greatly impact ectotherms, which depend on the environment to regulate their own body temperatures. In a new study published in the American Journal of Physiology- Regulatory, Integrative and Comparative Physiology, researchers were curious how exposure to varying temperatures would affect developing ectotherms. They answered this question using Drosophila melanogaster, commonly known as fruit flies. They exposed freshly laid eggs to ten different temperatures ranging from 12 to 32°C, the upper and lower limit of…
pgleick | December 1, 2016Among the different professional categories, scientists and engineers remain very highly respected by the public, at least compared to politicians, business leaders, the media, and even religious authorities. Part of this is due to the fact that success in the scientific enterprise depends on impartial analysis and independence from political ideology. And yet there are strong connections between science and policy: good policy without good science is difficult; good policy with bad science is impossible. Sure, there is plenty of bad policy made even in the face of contradictory scientific…
milhayser | November 24, 2016Today is about American tradition, and feeling grateful for all that we have been given. The first Thanksgiving represented the gratitude of American settlers towards the indigenous peoples who originally inhabited this country. It is about the men and women who came to North America on the Mayflower giving back to the men and women who helped them to survive in the 'new' world. It is about Tisquantum, a Patuxet enslaved by a Briton, sold in Spain, liberated by monks, and steeped in the English language before returning to his homeland and teaching the colonists to "catch eel and grow corn."…
jdupuis | November 11, 2016Update 2017.01.31: First post-inauguration chronology post is done, covering the first week of the Trump administration.
From the point of view of someone sitting North of the Canadian/US border, the results of this week's US Federal election are somewhat terrifying. And honestly and truly as a Canadian and a Torontonian, I say this without a bit of smugness. Been there, done that, if not quite on the same scale.
And by done that, I mean that I've often seen my mission to document important stories in the world. In the past, mostly Canadian or mostly in the library world and all basically…
pgleick | November 3, 2016My new Science Magazine article “Water Strategies for the Next Administration” has just been released (embargo lifts 11am Pacific, November 3rd; the print version will appear in the November 4th issue of Science). It identifies six major water-related challenges facing the United States and offers explicit recommendations for strategies the next Administration and Congress should pursue, domestically and internationally. The article begins:
“Issues around fresh water are not particularly high on the U.S. political agenda. They should be. Water problems directly threaten food production,…
gregladen | October 13, 2016Andy Lee Robinson started the recent trend of making compelling graphics about climate change that move. He did a version of the Arctic Ice Death Spiral (a term coined by Joe Romm), which was highly acclaimed but that did not go as viral as it should have at the time. Then, a version with additive ribbon graphs about three years ago. He called that the "waterfall diagram" and it was picked up and used by the BBC at the time. Not long after, he came up with the disappearing block of ice motif. And now, Andy has an updated version, here:
This is ice VOLUME, not the oft cited surface area.…

gregladen | October 7, 2016This morning I was forced to do the "get off my lawn" thing with the kids at the bus stop. They were systematically destroying the pavement around the common mailbox area down the street from my house, throwing chunks in the street. I lined them up and read them the riot act. They are children, so they can be excused for bering a bit stupid about life, and the guy down the street telling them to get off the lawn is part of the learning process for them.
And now it's your turn.
The right wing yahoos have already started yelling about conspiracies related to Hurricane Matthew. "They are…
gregladen | September 27, 2016LATEST UPDATE IS HERE. CLICK HERE FOR LATEST UPDATE.
Update: Wed Mid Day
Matthew weakened, strengthened, strengthening
Matthew has interacted with land masses in Hispaniola and Cuba to the extent that the storm weakened quite a bit, losing its temporary Category 5 status.
But, now Matthew is already showing signs of strengthening, and is likely to grow back to Category 3 or 4 status as it moves over the Bahamas. How bad a hurricane is when it makes contact with land depends in large part on the angle of the attack, and Matthew will likely be affecting several spots in the Bahamas at a…
gregladen | September 22, 2016Obviously, we need to stop the human enhanced extra greenhouse effect. There are a number of ways to approach this. Let me say right away that taking CO2, the main greenhouse gas of concern long term, out of the atmosphere is NOT one of the ways. Here's why: It takes energy to put Carbon into solid or liquid form. You get energy back when you move the Carbon into a gas form (as CO2). That is something of an oversimplification but long term, large scale, it is correct. Since, for the most part, the greenhouse effect is caused by the the generation of energy for use, which causes the movement…
gregladen | September 13, 2016This is a great cartoon by Randall Munroe that makes a very important point very effectively. Spread it around, love it, learn from it.
Here is an excellent video walkthrough of the cartoon, discussing its value as a communication tool.
But do ignore the details of the prehistory because the cartoonist has fallen into the same trap so many others have, well meaning in intention but simply a) not an expert on key things and b) unaware of the real consequences of getting certain things wrong.
When we represent prehistory, we represent humanity both past and present. It is not difficult to do…
