Final Thoughts In much the same way that the 1985 Apple Laserwriter gave birth to desktop publishing,

because meteorologists have yet to fully grasp why tornadoes form when they form and how to predict their paths.

Mcgovern's work could help meteorologists look for clues in storms that make tornado conditions more likely.

The eventual goal said William Gallus a meteorologist at Iowa State university is warn-on-forecast.

In other words meteorologists would be able to forecast tornadoes and issue warnings rather than waiting to see rotation

In their new study Uno and his team tested the radiocarbon dating technique on the tusks of two elephants that died in 2006 and 2008 as well as elephant and hippo teeth monkey hair and oryx horn.

and Uno are also using the radiocarbon dating technique to investigate the growth rate of animals. Now that we can determine growth rates in teeth we can use them as a tape recorder of sorts Uno said.

Wasser envisioned the carbon-14 dating technique being useful in a variety of ways. For example if used in combination with other methods that use DNA to determine the geographical origin of an ivory sample the carbon-14 dating technique could help investigators determine how recently hotspots for elephant poaching have been active.

Also if the ivory in a large seizure included samples of multiple ages it might suggest that the ivory was obtained from government stockpiles

Precision agriculture helps address that problem by improving weather forecasting and modeling and localizing it even within a particular farm.

The system then combines the field data with a diversity of public data from the National Oceanic and Atmospheric administration the National aeronautics and space administration and the U s. Geological Survey and private data from companies like Earth Networks.

In practical terms a farmer armed with precise weather forecasting information may choose to hold off on fertilizing an area of a farm expecting heavy rains;

and videos as well as chart the geographic coordinates of deforestation or degradation occurring within threatened areas said Gabriel Ribenboim a researcher who's leading the project for FAS.

You can't build a wall around the Arctic climate, counters Alan Robock, a climatologist at Rutgers University in New brunswick, New jersey.

Field trials to assess the ecological efficiency of organic and chemical fertilizers in different geographic and climatic settings are under way in Ethiopia, Kenya, Malawi, Uganda and Tanzania.

Out of sight the autonomous underwater vehicle (AUV) an oceanographic workhorse called a Remus begins gliding through the lagoon in a pattern that resembles the long linear passes of a mowed lawn.

For a group like Bentprop the use of advanced oceanographic instruments is a huge technological leap forward

The vehicles come from the University of California San diego's Scripps Institution of Oceanography and the University of Delaware

The funding enables oceanographers to test new technologies while helping Bentprop locate WORLD WAR II airmen an effort they named Project Recover.

The Echoscope or multibeam volume imaging sonar does enabling oceanographers to map topography accurately and in high enough resolution to distinguish man-made objects.

Terrill describes it as the oceanographic seafloor-mapping equivalent of ultrasound sonar used to look inside the human body.

Oceanographers and biologists studying living structures such as coral reefs could also benefit from it; 3-D models would enable them to detect how ocean acidification

hope you don't mind a bit of geographical lesson don't want to be assuming after all. The foks of the Indus Civilization were a few among the Bronze age peoples to have codified a standard system of weights and measures.

A new study from Colorado State university geology professor Ellen Wohl finds that these beaver meadows store carbon temporarily sequestering greenhouse gases from the atmosphere.

since the late Jurassic when it was about 2500 ppm vs today's 400 ppm.

Climatologists understand the effect the Sun has on our climate and it's minor compared to

and millions of years. just 10000 years ago we were in the Pleistocene. A climate era of 10x the natural variance of the Holocene (think global temperature changes of 1. 5 C per decade rather than per century.

If you look back 2 to 3 million years you find a heightened period of CO2

and are willing to espouse the climatologist models without even looking at the data Is the planet warming?

Am I a climatologist? Nope. I'm an engineer. But I'm not putting forth new data.

I'm looking at the data climatologists have and saying: You've got nothing here.

Chances are if you're a climatologist you're going to be spouting the same biased data that every other climatologist is worried about.

There are no climatologists that have varying views on the issue because their entire goal in life is to prove that Climate Change is a thing

Saying 99%of climatologists agree climate change is occurring is like saying 99%of priests agree that god is omnipotent.

Just claims of climatologists are biased and lying to keep their jobs. Good science boys.@@Frosttty really dude.

Man-made climate change is quite arrogant and convenient for climatologists. Even though I am not a climatologist as an computer scientist

I can smell bs from a mile away. And so can other scientists and engineers. I don't have to make up reasons to have software engineers exist.

since 40 years ago on the first Earth day celebration when climatologists and various other climate experts claimed we were heading for the end of the world in the next 15 years.@

Oh they're just trying to justify their climatologist jobs...We understand how CO2 captures

This is less helpful in dating on more geological time scales but the various radiometric dating techniques used on those scales have other means of control

For this reason radiocarbon dating only works for organisms that obtain their carbon from air via carbon dioxide.

my guess as to the reason why is that carbon-14 dating is quite expensive and the purpose of the record is actually to help calibrate radiocarbon dating

so they didn't need to have annual resolution). Over the past 3000 years there have been 3 sharp spikes in carbon-14 levels over a short period of time.

Also@monkeybuttons while it's true that carbon-14 dating isn't perfectly precise this study was based on tree rings

and then build a calibration curve to make radiocarbon dating more accurate. Before 12000 years that record consists of data from marine sediments.

and Cheirolepidiaceae--a now-extinct family of conifers known only from the Mesozoic. This tells us that 150 million years ago the ancient forests of western North america consisted of members of these three families.

Additionally it will be useful in a number of other disciplines including geology archaeology biodiversity glaciology and rangeland ecosystem research.

We look at the weather forecast every day to tell us how to prepare for tomorrow and that is because we can predict the weather with a large degree of confidence.

And because of the country's climate and geography irrigation is now widespread burdening rivers and groundwater supplies.

and Japan--combined a hydrological model with domestic and international trade simulations to determine the efficiency of China's food trade in terms of water use as well as the role of foreign trade in this virtual water-trade system.

We found that climate engineering doesn't offer a perfect option said Daniela Cusack the study's lead author and an assistant professor of geography in UCLA's College of Letters and Science.

and soil ecology teamed up with experts in oceanography political science sociology economics and ethics. Working under the auspices of the National Science Foundation the team spent two years evaluating more than 100 studies that addressed the various implications of climate engineering and their anticipated effects on greenhouse gases.

instead of eliminating it from the hydrological cycle completely. It's all related to rebalancing the supply-demand equation.

You said that wastewater is eliminated often from the hydrological cycle. What do you mean? JF:

and the tech that might save humanshumans are considered now to be the greatest force impacting the geology of Earth.

And as such the Athropocene the age of humans is proposed the term for our current geological time scale,

marking the end of the Holocene about 200 years ago. If technological innovation brought humans to a population of 7 billion can it also make the future planet livable?

Can we innovate our way out of climate and geologic problems? As the American writer Stewart Brand wrote in his 1969 Whole Earth Catalogue:

are worried we enough about saving human civilization to make this time scale, the Anthropocene, more than a mere speck in the geologic time scale?

The Anthropocene is a potential new geologic era in the Earth history. It been proposed by some scientists because the most recent era,

the Holocene, may have come to a close, and we humans where the â Å anthro â Â part of the name comes from may be largely responsible for the shift.

The Holocene got its start when the last ice age ended and we shifted from a glacial ice covering much of the northern hemisphere,

which was the end of the Pleistocene. The Holocene may have ended when James Watt invented his steam engine.

And we started pumping out CO2 by burning coal. So in addition to the climate change we have raised greenhouse gasses in the atmosphere by about 100 parts per million (ppm)

Beyond climate change, how have affected we humans the Earth to such a degree that we warrant our own geologic era?

We also do a lot of things that are geologic in scope. We move more earth and stone than all the world rivers.

And we have created some new compounds that will be in the geologic record for a long time to come, the most ubiquitous

That is a huge change compared to only a third of the Earth surface was covered by ice at the end of the Pleistocene and the shift into the Holocene,

We are putting carbon that was locked away during the Cretaceous period 300 million years ago, back into the atmosphere as CO2.

That is if we want the Anthropocene to be more than a blip in the geologic record.
