Here is the monthly microwave report from Dr. Spencer. Although he thinks it reflects global temperatures, it really is a measure of how much heat energy is being thrown into space. If the Earth didn't do this efficiently, we wouldn't be here to talk about it. The area under the graph is approximately proportional to the amount of heat energy thrown. A wider peak warms the nether
Sometime soon, a flock of “Climate Birds” could be ascending from a former NATO base in northeast France to take the measure of climate change around the
Alum James Kocher (MSSM ‘13) works in the photovoltaics monitoring sector where he helps clients measure and analyze photovoltaic (PV) solar production. James currently designs and implements data monitoring systems for large commercial and utility scale PV
Imagine I look at a numerical weather model forecast that predicts the temp. at 5 PM the next day, will be 30C where I live. The next day, I go out at 5 PM and measure 29C instead. Was the model wrong? Probably, since models are just numerical representations of the atmosphere with some processes explicitly predicted, while other processes (like clouds) approximated from other model variables. There is also

The REF (Research Excellence Framework) is a time-consuming exercise that UK universities have to go through every few years to assess and demonstrate the value of their research to the government; the way funding is allocated between universities is largely dependent on the results of the REF. The exercise is widely resented, in part because the processes
Despite its name, the NASA Goddard Institute for Space Studies (GISS) has in recent years concentrated on planet Earth–mainly, its widely used computer models used by scientists around the world to measure and predict the impact of greenhouse gases on climate. This week NASA announced that the Earth Institute-affiliated center will also play a leading role in a new initiative to
On Wednesday, January 28, the Senate voted against Amendment 48 which would allow the federal Environmental Protection Agency (“EPA”) to regulate hydraulic fracturing (“fracking”) on state and private lands. The measure was presented by Senator Kirsten Gillibrand (D-NY) as a negotiated amendment to the Keystone XL Pipeline Act. The amendment would have repealed sections of … Continue
With wind chills almost certainly reaching -30 or lower across the Eastern U.S. tonight, I thought you might be interested in some information about what it does and does not measure. First of all, water will not freeze at 33 degrees, no matter how hard the wind blows, and the wind chill is NOT “how cold it feels”. What it does measure is the rate of heat loss due to
Super-typhoon Neoguri, first super-typhoon of 2014imaged on July 6 (?) by NOAA/EPAThree inches of rain PER HOUR??? I wonder for how many hours!! Waves up to 14 meters (45')? I have friends on Okinawa and wish them well (and also asked them to send a first hand report!) The storm is expected to work its way up to mainland Japan by Wednesday. The highest danger is for Miyako-jima, in the center of the archipelago. As I write this (Monday a.m. PDT) gusts of up to 270 [...]
crystallographic sector zoning is a phenomenon that causes
all sorts of headaches for geochemists and petrologists. Basically, as different crystallographic
faces grow in a medium (e.g. magma), they have different selectivities for different
elements. If you want to measure how
much of a particular element a growing crystal scavenges from its surrounding,
and you don’t measure all
The idea of capturing carbon and storing it away offers an appealing solution to the “greenhouse gas” emissions from fossil fuels that are warming the planet. But how can we measure the process well enough to know what sort of impact the technology has? Doctoral student Yinghuang Ji is working on it, along with Klaus
In the annals of dinosauriana, size and apparent ferocity count a great deal towards fame. By that measure,
The BC Northwest Community College, School of Exploration & Mining is to be congratulated on a superb set of courses offered in 2014. Lori Knorr sent me this list: Drill Core Technician Basic Training March 10 – 14, 2014. Develop and apply the technical skills to observe, measure and record information from diamond drill core
“O, it is excellentTo have a giant’s strenght, but it is tyrannous to use it like a giant.” “Measure for Measure” Act 2, Scene 2 3. – Bones of Giants Until the 17th century the discovery of skeletons of giants was a quite common event. In January 1546 and then in the years 1564, 1580
Early Jurassic (late Pliensbachian) CO2 concentrations based on stomatal analysis of fossil conifer leaves from eastern Australia
Authors:
M. Steinthorsdottir and V. Vajdab
Abstract:
The stomatal index (a measure of stomatal density) of an extinct Australian Early Jurassic araucariacean conifer species, Allocladus helgei Jansson, is used to reconstruct the atmospheric carbon
Coal-fired power plants are responsible for one third of all U.S. carbon dioxide emissions each year. Recently President Obama proposed a plan to combat climate change including a measure that will regulate emissions from new and existing coal-fired power plants. The plants will likely only be able to meet these new standards by using clean coal technology, but is the technology ready for the new regulations Obama will
Emflume instrumentation entertainment. from Steve Gough on Vimeo.Wet your finger. Blow on it. You can sense the cooling.Try it with a dry finger. You'll probably sense that, too. Feel the cooling?Your body works to maintain 37 °C . Air moving past it at a lower temperature cools it, that's why you sense the cooling of your finger.Science lit is full of "thermal anemometry" papers, and you can buy instruments that measure airspeed this way -- a body, [...]
