gregladen | November 26, 2015Sandra is a Category 4 hurricane in the Eastern Pacific. The storm will hit Mexico.
Sandra breaks several records. It is the first observed Category 4 hurricane on Thanksgiving Day. It is the latest major Western Hemisphere hurricane observed. It is the latest Category 4 storm in either the eastern Pacific of Atlantic basins. Most likely, Sandra will become the latest landfalling tropical cyclone on record for Mexico.
(Jeff Masters has details.)
Sandra will come near the southern time of the Baja late Friday, but will likely be a tropical storm at that point. The storm will come ashore…
gregladen | November 25, 2015Here we look mainly at bird books, but I wanted to also mention a couple of other items on non-birds. I've mixed in some new books along with a few other books that have come out over the last couple of years, but that are still very current, very amazing books, and since they have been out for a while, may in some cases be picked up used or otherwise less expensively.
Let's start with the least-bird like book, one that will be a must have for anyone traveling to or studying Africa. This is The Kingdon Field Guide to African Mammals: Second edition. This is a newly produced edition of this…
gregladen | November 25, 2015I mention a couple of kids books in my overviews on Fossil and Evolution Books and Books about Climate Change. Here are a few excellent science and computer programming (aka coding) books for kids.
Geology book for kids
The Incredible Plate Tectonics Comic: The Adventures of Geo, Vol. 1 is a good stab at making a comic that teaches some science.
We follow the adventures of Geo and his robotic dog, Rocky as the visit the ancient supercontinent of Pangea. This journey is pursuant to Geo's upcoming test in his geology class.
What is the center of the Earth made out of? How do volcanoes work?…
gregladen | November 25, 2015Over the last several months, a lot of great books on fossils and evolution (as in paleontology) have come out. I've selected the best for your consideration. These are great gifts for your favorite science-loving nephew, life science teaching cousin, or local school library. Actually, you might like some of these yourself.
Let's start off with a kid's book: Grandmother Fish: a child's first book of Evolution by Jonathan Tweet.
From the blurb:
Grandmother Fish is the first book to teach evolution to preschoolers. While listening to the story, the child mimics the motions and sounds of our…
gregladen | November 25, 2015It is time to update the list of recommended books on climate change and global warming. I assume that with the holidays coming, you will want to give some people some science books, and climate change related books should be near the top of the list for you. I'm doing a separate post on evolution related books, and another on bird and nature books, as well.
I'm going to keep this short and focus on a small number of books. To get on this list the book has to be good and current, with two notable exceptions (see below).

gregladen | November 25, 2015The World Meteorological Organization has announced that they expect 2015 to be the warmest year on record, and that we are in the warmest five year period on record. We are speaking here of global surface temperatures, though similar descriptions probably apply to the upper 2000 meters or so of the ocean as well.
The global average surface temperature in 2015 is likely to be the warmest on record and to reach the symbolic and significant milestone of 1° Celsius above the pre-industrial era. This is due to a combination of a strong El Niño and human-induced global warming, according to the…
gregladen | November 24, 2015First and foremost, depending on when you are reading this, TAKE THE TURKEY OUT OF THE FREEZER.
But seriously, Thanksgiving is, to me, one of the more interesting holidays. It is a "feast." You knew that already, but what you may not have known is that "feasting" is a human activity found world wide and often studied by anthropologists. Feasting is not exactly a human universal, as it is rare in foraging societies. But whenever certain conditions arise, feasting seems to emerge as a part of normative culture.
As a human, you may automatically think of feasting as a pleasantry, a fun thing…
gregladen | November 23, 2015I know a lot of you are looking for ideas for science-related children's presents for Christmas or whatever holiday you like to celebrate this time of year. I have a couple of ideas, and hopefully you will add some of your ideas below. Not everything that helps encourage the skills of scientific tinkering is found in a science kit, and I'll provide a few ideas for toys that do this. Also, some of the best science experiments are found by using things that don't come in kits, but by following the advice in books. So I'll suggest a few books as well. Purely science kits or tools are of…
gregladen | November 23, 2015I'm not going to say that Ron Howard is old or anything, but he isn't Opie any more. (And, in fact, it has been fascinating and inspiring to watch his career, by the way.) Anyway, Howard produced a new documentary with National Geographic called "Breakthrough: The Age of Aging, which premieres Sunday, November 29 at 9 pm et on National Geographic Channel. And, pursuant to this, National Geographic's web site is sponsoring a Roundtable on the topic. The roundtable addresses the question, "By treating aging as a disease are we just prolonging the inevitable or can we change the course of our…
gregladen | November 22, 2015A few days ago a team of climate scientists (Catherine Ritz, Tamsin Edwards, Gaël Durand, Antony Payne, Vincent Peyaud, and Richard Hindmarsh) published a study of “Potential sea-level rise from Antarctic ice-sheet instability constrained by observations.”
The study asked how much Antarctic ice sheets might contribute to global sea level by 2100 and 2200 AD. The results contradicted some earlier estimates which are on the high end, but conformed very closely to the current IPCC estimate, raising that number by a negligible amount.
The authors note that rising seas due to global warming is a…
gregladen | November 19, 2015Record daily high and low temperatures happen now and then at a give weather station. In a normal, stable climate the number of record highs and record lows should be about even. But with human-caused global warming, record highs are expected to be more common than record lows. And they are.
Climate Nexus has this handy dandy widget to track record highs and record lows over the previous year.
Click to see the 1950s, when global warming was not as severe at it is today. Then look at the 1990s when things were starting to take off. Then look at the last year.
Here is NCAR's Gerry Meehl…
gregladen | November 19, 2015In 1817, Karl August Weinhold had a go at a real-life Frankenstein's monster -- only in his version he uses a cat. The German scooped out the brain and spinal cord of a recently dead cat. He then pured a molten mixture of zinc and silver into the skull and spinal cavity. He was attempting to make the two metals work like an electric pile, or battery, inside the unfortunate cate, replacing the electrical of the nerves. Weinhold reported that the cat was revived momentarily by the currents and stood up and stretched in a rather robotic fashion!
It's Alive!!!!
Weinhold's reanimated cat was…
gregladen | November 19, 2015This month is the twentieth anniversary of the discovery of exoplanets, which are really just planets that are not in our solar system. (Frankly, I dislike the term exoplanet. It is so solarcentric.)
When you think about it, the discovery of planets outside our solar system (we need a word for that) is a special thing. On a graph of how expected and mundane a scientific discovery is vs. how exciting a scientific discovery is, these planets are distant outliers.
For years astronomers and cosmologists and others assumed that stars would generally have planets around them, or at least, this…
gregladen | November 19, 2015Albert Einstein finished up his General Theory of Relativity in November, 1915, 100 years ago. Because we use Base 10, this is significant.
General Relativity ties together curvature in spacetime with the energy and momentum of matter and radiation. This has a lot to do with gravity. Einstein himself wrote the book on General Relativity, but it has been covered in a lot of other places as well, including a recent treatment by historian of science Tom Levenson, The Hunt for Vulcan: ... And How Albert Einstein Destroyed a Planet, Discovered Relativity, and Deciphered the Universe.

gregladen | November 18, 2015Mike Haubrich and I are developing a science oriented podcasting effort. It will be called "Ikonokast" (all the good names, like "The New York Times" and "Apple" were taken). We decided to enhance the podcast with a WordPress based blog site, perhaps with each page representing one podcast, and containing backup and supplementary information.
Here is the site, set up and running.
After considering our options, we decided to try using a Digital Ocean "Droplet" to host a WordPress blog. Here, I want to tell you how that went, and give a few pointers. This might be a good idea for some of…
gregladen | November 18, 2015NOAA has just followed JMA and NASA in reporting on October's average global surface temperature. The surface temperature is the combination of thermometer-at-head-height data and sea surface temperatures, averaged out for the planet. Several groups track this data, and though there is much overlap in the instruments used, each group has its own way of processing the data to eliminate errors and biases, and to adjust for missing information (such as large regions with little data).
NOAA points out that October had the greatest above-average departure from average for any month. Also, NOAA…
gregladen | November 18, 2015There is a new study by a French/English team looking at the rate at which Antarctic glaciers might contribute to sea level rise, due to global warming, between now and 2100 and 2200 AD.
The study produces several estimates, but suggests that glaciers in Antartica might contribute as much as 30 cm by 2100 and 72 cm by 2200. That is a large amount of sea level rise, but it is actually less than other studies that rely more on paleoclimate evidence have suggested. I personally have something of a bias towards paleo evidence; Good paleo evidence is evidence of what actually happened,…
gregladen | November 17, 2015Michael Mann has an editorial on Scientific American's site putting the well known 2.0C limit in perspective for the upcoming climate talks in Paris.
Mann makes a number of important points in his essay (read it here: Meeting a Global Carbon Limit Is Cheaper Than Avoiding One) but there is one point that I want to underscore.
The key factor is that there are technological innovations and economies of scale that emerge only in the course of actually doing something.
Here's the thing. Let's say you were suddenly in charge of one trillion dollars of money that could be used to address climate…
gregladen | November 17, 2015Changes in the daily variability of high and low temperatures in certain regions may stress wild bird populations. A new study of semi-wildish Zebra Finches demonstrates this. I have a post on the research here, at 10,000 birds. Have a look!
gregladen | November 17, 2015Climate Change: What Everyone Needs to Know® by Joe Romm is just out, and is the most up to date examination of climate change science, the effects of climate change on humans, policy related problems, and energy-related solutions. Everyone should read this book, and if you teach earth system sciences you should consider using this book as a guide in your teaching, or in some cases, assigning it in class. The book is written to be read by general audiences, so it would work well in a high school or college setting.
As Romm points out, climate change will have more of an impact on humans,…
