A friend asked me this question: Which formed first, Andamans or Lakshadweep? My answer was- Lakshadweep islands as a system of living coral atolls etc is a Holocene system (past 12 thousand  years). These coral communities rest on earlier Pleistocene reefs. So the history of reefs and atolls is probably a Quaternary phenomenon going back several hundred thousand years when ice age driven

The 2 Million Year Melee: Neanderthals vs. Humans

Given their adaptation to cold climes and their advanced, albeit under-appreciated, skills, how were Neanderthals beaten out by their human counterparts? The answer lies in a combination of culture and genetics that enabled the successful radiation of

Within the rocks of Fall Brook, near Geneseo, NY, sometimes you'll find odd dark colored fossils that look as though someone poured chocolate on the rock. I knew it was a fossil of some kind but getting a piece to reveal itself face up was not an easy task. So I kept a few pieces in the hopes that one day I would figure out what it could be. Now I may have an answer. While I was looking through the plates within the Paleontology of New York, volume  VI, I came across an illustration that [...]

Think of the word "desert". What''s the first picture that pops into your mind? Is it Saguaro Cacti, like an old western? Is it cliffs and spires like other old westerns? Is it a painted desert, like an old Disney movie or a Roadrunner cartoon? Or is it an endless sea of sand? At different times, I've had all those stereotypes established in my head. The California desert is the one I

What is 4D seismics?

4D seismics is hype. It’s the new stuff. But 4D is also somewhat obscure, so when I started telling people telling that I had landed a job in 4D seismics, the most common question was: So, Jesper, what’s the fourth dimension. The answer always causes some disappointment. “It’s time.” They were hoping for some obscure […] The post What is 4D seismics? appeared first on The Way of the Geophysicist.

What exactly is the greenhouse effect? And what does it look like if we view it from a new angle? Of course, we know the answer, and Raymond Pierrehumbert has written an excellent paper about it (Infrared radiation and planetary temperature). Computer code used in climate models contain all the details. But is it possible

In the Southern Ocean, a Carbon-Dioxide Mystery Comes Clear 

State of the Planet [2016-02-03 19:51:28]  recommend  recommend this post  (209 visits) info
Twenty thousand years ago, low concentrations of carbon dioxide in the atmosphere allowed the earth to fall into the grip of an ice age. But despite decades of research, the reasons why levels of the greenhouse gas were so low then have been difficult to piece together. New research, published today in the leading journal Nature, shows that a big part of the answer lies at the bottom of the

It’s official: 2015 was the warmest year on record. But those global temperature records only date back to 1850 and become increasingly uncertain the further back you go. Beyond then, we’re reliant on signs left behind in tree rings, ice cores or rocks. So when was the Earth last warmer than the present?The Medieval Warm Period is often cited as the answer. This spell, beginning in roughly 950AD and lasting for three centuries, saw major changes to population centres across the globe. This [...]

Alex Bellos writes an occasional puzzle column for the Grauniad. Yesterday he was asking for ways of inserting maths symbols into the list of numbers 10 9 8 7 ... 1 so as to make the expression evaluate to 2016. I quickly got an answer (10+9)*8*(7+6)+5*(4+3+2-1) but jules said I could only tweet it if I found three ways of doing it. A second solution is reached by noting that 10*9*(8+7+6)

After a rather long hiatus (at least 3 years overall) from palaeoart, taking on a moonlighting "career" in the board game industry, I've (Craig) decided to travel back into deep time recreation.I'm looking into making a series of little educational animations about Dinosaurs and other prehistoric critters as they behave/appear in movies vs. what we know in the fossil record.As this is just for fun I have no strict deadline set.

So for some reason I got invited to participate in the latest Bray and von Storch survey of climate scientists, having not (IIRC) been asked previously. I barely got started on the meat of it before giving up. Screeds of hopelessly vague multi-choice questions with no context, like: how well do you think climate models can deal with clouds (answer from "very adequate" to "very inadequate").

Why Prometheus failed to ask the big questions it pretended to ask...

I suppose it's rather late to be commenting on a film from 2012, but I just recently came up with a reason why I didn't like the film Prometheus. Or at least one reason...When Prometheus came out, all the critics and many fans on the internet praised how the film asked big questions. I never got that. To me Prometheus didn't ask big questions, it only pretended to do so.For instance, it is made pretty blatant in the film that characters in Prometheus are asking about where we come from. [...]

Why are dinosaurs extinct? Let me google that for you. theguardian.com Let’s clear something up right away. Dinosaurs aren’t extinct. Not entirely. Every magpie, pigeon, penguin, and ostrich alive today – every single bird – is a dinosaur. They’re all descendants of small, toothy, feathery dinosaurs that hopped and fluttered around from the Jurassic era

It’s not just John Stewart and Stephen Colbert, now you can add  Bill Maher who called out Rick Santorum, when he made a ridiculously false claim about climate science. Santorum “claimed” that a study showed 57% of scientist had doubts about whether CO2 controls our climate, and Maher responded with (quoting here) “I don’t know what ass you’re pulling that out of..” A little research online leads to the answer
