Global Warming DelusionsBy DANIEL B. BOTKINGlobal warming does.docxwhittemorelucilla
Global Warming Delusions
By DANIEL B. BOTKIN
Global warming doesn't matter except to the extent that it will affect life -- ours and that of all living things on Earth. And contrary to the latest news, the evidence that global warming will have serious effects on life is thin. Most evidence suggests the contrary.
Kilimanjaro's shrinking ice cap is not directly related to global warming.
Case in point: This year's United Nations report on climate change and other documents say that 20%-30% of plant and animal species will be threatened with extinction in this century due to global warming -- a truly terrifying thought. Yet, during the past 2.5 million years, a period that scientists now know experienced climatic changes as rapid and as warm as modern climatological models suggest will happen to us, almost none of the millions of species on Earth went extinct. The exceptions were about 20 species of large mammals (the famous megafauna of the last ice age -- saber-tooth tigers, hairy mammoths and the like), which went extinct about 10,000 to 5,000 years ago at the end of the last ice age, and many dominant trees and shrubs of northwestern Europe. But elsewhere, including North America, few plant species went extinct, and few mammals.
We're also warned that tropical diseases are going to spread, and that we can expect malaria and encephalitis epidemics. But scientific papers by Prof. Sarah Randolph of Oxford University show that temperature changes do not correlate well with changes in the distribution or frequency of these diseases; warming has not broadened their distribution and is highly unlikely to do so in the future, global warming or not.
The key point here is that living things respond to many factors in addition to temperature and rainfall. In most cases, however, climate-modeling-based forecasts look primarily at temperature alone, or temperature and precipitation only. You might ask, "Isn't this enough to forecast changes in the distribution of species?" Ask a mockingbird. The New York Times recently published an answer to a query about why mockingbirds were becoming common in Manhattan. The expert answer was: food -- an exotic plant species that mockingbirds like to eat had spread to New York City. It was this, not temperature or rainfall, the expert said, that caused the change in mockingbird geography.
You might think I must be one of those know-nothing naysayers who believes global warming is a liberal plot. On the contrary, I am a biologist and ecologist who has worked on global warming, and been concerned about its effects, since 1968. I've developed the computer model of forest growth that has been used widely to forecast possible effects of global warming on life -- I've used the model for that purpose myself, and to forecast likely effects on specific endangered species.
I'm not a naysayer. I'm a scientist who believes in the scientific method and in what facts tell us. I have worked for 40 years to try to improve our enviro ...

2. BRAZIL: Dengue Cases Almost Triple As New Strain Spreads
Health authorities in Brazil say there has been a steep rise in the confirmed cases of dengue fever
this year. More than 200,000 people were infected in the first seven weeks of 2013 compared to
70,000 in the same period last year, official figures suggest.
The southern state of Mato Grosso do Sul has been hardest hit. Officials said the cases were likely
to rise as the rainy season increases the risk of reproduction of the mosquito which transmits the
disease. Health Minister Alexandre Padilha said that despite the higher incidence, the cases had
been less severe than those recorded last year.

41 last year. According to Mr Padilha, these figures showed that the authorities were following
the right strategies in their fight against the fever. He said extra training given to health care professionals and improvements to
the network of basic care providers had clearly paid off.
But Mr Padilha warned state authorities not to let down their guard as the rainy season could exacerbate the situation, with stand-
ing water providing an ideal breeding ground for the mosquitoes carrying the disease. Apart from Mato Grosso do Sul, seven other
states across southern and central Brazil have been affected by the epidemic.
More than half of the cases have been caused by the DENV-4 strain of the virus, which was first detected in Brazil in 2011. Mr
Padilha said that because the strain was still relatively new to the country, more people were susceptible to infection.
There are four known types of dengue fever. Once people are infected by one type, they become immune to that variation, but not
to other strains.

HEALTH: Peruvian Engineers Develop a Device to Treat Glaucoma*
Engineers Carlos Ojeda and Gerardo Rojas from Piura University have developed
an innovative device that can treat glaucoma effectively. They had the advice of
Peruvian physicians and coordinated with doctors from the Polytechnic University
of Madrid.
The silicon device has three very small components: a plate, a tube and a valve.
The device can be surgically implanted over the sclerotic part of the eye. “This is a
simple design, both in size and in shape, and make surgery easier” says Ojeda.
Also, it is biocompatible, guaranteeing that it will not be rejected by the human
body.

uid can rise the valve and go through a tube to a plate. This mechanism assures a
flow in one direction, avoiding return to the previous chamber, thus reducing the risk of hypotony (decrease of the muscle tone),
produced by excessive drainage.
The plate receives the intraocular liquid, forming a capsule between the sclerotic and the conjunctiva, which absorbs and drains
this liquid.
The plate counts on two orifices which allow the increase of reception capacity up to 70 microliters. “The orifices also help for the
liquid film to be more plain to facilitate draining” says Ojeda.
ECONOMIC BENEFITS. At the moment, these devices are not manufactured in Peru, and imported ones are expensive. However,
manufacturing these devices locally would reduce their cost by half the amount of the international price,” points out Ernesto Ar-
riola, project assistant.
It is expected that this device will be ready for distribution by December of this year.

3. S C I E N C E : C o l o m b i a n Scientists Reconstruct Russian Meteor's Path By Joseph Serna
Colombian scientists have reconstructed the interstellar path of a meteor that flamed
across the Russian skyline this month and smashed into the countryside, leaving hun-
dreds of people injured.
The meteor, estimated to be about 45 feet across and weighing 10,000 tons, was flung
toward Earth as it orbited around the sun. It wasn’t a declaration of war by bugs on
Klendathu after all. Apparently, it was just a matter of time before it hit, researchers
concluded in a study published this week on ArXiv.org.

kilometers (930 miles) east of Moscow,by tonynetone (flickr user).
Under Creative Commons License. The study's authors, from the University of Antioquia in Medellin, Colombia, triangu-
lated the meteor’s position using landmarks, shadows and camera footage. They se-
lected two points in the meteor’s path to calculate its trajectory: when it burned through the atmosphere and the light emitted
grew brightest, acting like a giant torch over the Russian sky, and when it exploded and blasted meteorites across the landscape.
The researchers estimated the space rock’s height by measuring the shadow it cast on light poles seen in so many videos taken by
dashboard-mounted cameras.
Other data points included the lake near Chelyabinsk where a meteor fragment landed and left a huge hole in the ice, and the cen-
ter of Korkino, a small town to the south, where video showed the meteor passing overhead.
The Chelyabinsk meteor was an Apollo asteroid, the team concluded. Apollo asteroids are a class of asteroids with longer elliptical
orbits than Earth. When they pass between Earth and the sun, they cross our orbital path.
The meteor struck Earth going about 40,000 mph, scientists estimated in the days after impact.
Below is a video the team created of the meteor’s estimated orbit for the last four years.
A copy of the paper is available here. A video of the meteor's orbit compared to Earth and Mars is below.

OCEANS: Seals Retrieve New Data on Deep Antarctic Waters
To learn more about "Antarctic bottom water" -- very dense, very deep layers of
water beneath the southernmost parts of the planet -- scientists deployed a team
of elephant seals to retrieve hard-to-get data near the ocean floor. The data will
help researchers understand how Antarctic bottom water affects the oceans' circu-
lation.
The seals, which had been outfitted with head sensors, helped confirm the exis-
tence of a fourth area of Antarctic bottom water, with the additional support of
satellite data and underwater moorings. This new data could help with future cli-
mate change modeling. "The seals went to an area of the coastline that no ship
was ever going to get to," said Guy Williams, of Antarctic Climate and Ecosystem
CRC in Tasmania, Australia, who co-authored the study.
Twenty Southern Ocean elephant seals finished four data dives per day during the
2011 study period, near east Antarctica's Davis Station.
"Several of the seals foraged on the continental slope as far down as 1,800 meters,
punching through into a layer of this dense water cascading down the abyss," Wil-
liams said in a statement. "They gave us very rare and valuable wintertime meas-
urements of this process" (Pauline Askin, Reuters, Feb. 26).

4. CONSERVATION: Beautiful Colors and Shapes of Undersea Creatures
Starfish or sea stars are echinoderms belonging to the class Aster-
oidea. The names "starfish" and "sea star" essentially refer to
members of the class Asteroidea. However, common usage fre-
quently finds these names also applied to ophiuroids, which are
correctly referred to as "brittle stars" or "basket stars". About
1,800 living species of starfish occur in all the world's oceans, in-
cluding the Atlantic, Pacific, Indian, Arctic and Southern Ocean re-
gions. Starfish occur across a broad depth range from the intertidal
to abyssal depths of greater than 6,000 m (20,000 ft).
Starfish are among the most familiar of marine animals found on
the seabed. They typically have a central disc and five arms,
though some species have many more arms than this. The aboral

with overlapping plates. Many species are brightly coloured in vari-
ous shades of red or orange, while others are blue, grey, brown, or drab. Starfish have tube feet operated by a hydrau-
lic system and a mouth at the centre of the oral or lower sur-
face. They are opportunistic feeders and are mostly predators
on benthic invertebrates. Several species having specialized
feeding behaviours, including suspension feeding and adapta-
tions for feeding on specific prey. They have complex life cycles
and can reproduce both sexually and asexually. Most can regen-
erate damaged or lost arms.
About 1,600 living species of starfish are known. Echinoderms
maintain a delicate internal electrolyte balance in their bodies
and this is only possible in a marine environment. This means
starfish occur in all of the Earth's oceans, but are not found in
any freshwater habitats. The greatest variety of species is found
in the tropical Indo-Pacific. Other areas known for their great
diversity include the tropical-temperate regions around Austra-

lia, the tropical East Pacific and the cold-temperate water of the
North Pacific (California to Alaska). All starfish live on the sea
bed, but their larvae are planktonic, which allows them to disperse to new locations. Habitats range from tropical coral
reefs, rocks, shell brash, gravel, mud, and sand to kelp for-
ests, seagrass meadows and the deep-sea floor.
Starfish and other echinoderms pump water directly into
their bodies via the water vascular system. This makes them
vulnerable to all forms of water pollution, as they have little
ability to filter out the toxins and contaminants it contains.
Oil spills and similar events often take a toll on echinoderm
populations that carry far-reaching consequences for the
ecosystem.
