as “an increase in the average temperature of the Earth’s atmosphere,” either by “human industry and agriculture” or by natural causes like the Earth has “experienced numerous” times “through its history.” * Some writers use the phrases “global warming” and “climate change” to mean temperature changes strictly caused by human activity.   Other writers use adjectives such as “man-made” and “anthropogenic” to distinguish between human and non-human causes.  (“Anthropogenic” means “of human origin,” and “AGW” stands for “anthropogenic global warming.”) * Just Facts’ Standards of Credibility require the use of “language that is precise and unambiguous.” Hence, when human causes are stated or implied, this research uses terms like “man-made” and “human-induced.” * The greenhouse effect is a warming effect caused by certain gases that retain heat from sunlight. Without such gases, the average surface temperature of the Earth would be below freezing, and as explained by the , “life, as we know it, would not exist.” The global warming debate is centered upon whether added greenhouse gases released by human activity will overheat the Earth and cause harmful effects. * Human activities currently release about 37 billion metric tons of CO2 per year, which equates to about 5% of natural CO2 emissions.Natural processes absorb the equivalent of all natural emissions plus about 57% of man-made emissions, leaving an additional 16 billion metric tons of CO2 in the atmosphere each year. † In permafrost regions, perennial snow accumulations trap air bubbles that leave records of past airborne CO2 concentrations,   and because regional CO2 concentrations vary by less than 10 parts per million over the Earth, these local records are globally representative.  * Instruments located on satellites can measure certain properties of oxygen that vary with temperature.PPT is currently servicing / supporting approximately 70 presses / pre-print applications world-wide that operate with wide web Cobden Chadwick press designed originally by PPT engineers whilst in the employment of Cobden Chadwick. The latter is generating significant interest with those customers operating Cobden Chadwick presses as this replaces old obsolete equipment with modern state of the art gear-less technology, whilst at the same time keeping capital expenditure to a minimum. The new true closed loop system we are offering eliminates all ink unit backlash and drastically reduces maintenance procedures. No other press manufacturer offers the 'true closed loop' ink deck positioning system working on pressure settings.Our main core business is offering service support to all Cobden Chadwick press users. PPT is now offering complete gear-less press lines or new gear-less C. Each print unit operates on pressure settings as opposed to indexed movement. This innovative development is already operating successfully in a flexo production environment in the USA & Spain and PPT has reconfigured this unique technology to adapt to wide web pre-print presses.Choose: No Frames Layout Choose: Human Evolution Frames .I have integrated this web page on human evolution into an electronic text, " Nature's Holism - Holism.One of these was a series of buoys, each containing thermometers located ten feet above the water and at one foot below the water.The study found that water temperatures increased on average by 0.23ºF (0.13ºC) per decade between 19, while air temperatures cooled by 0.02 to 0.09ºF (0.01 to 0.06ºC) per decade during the same period. examined the locations of 1,007 of the 1,221 monitoring stations used to determine average surface temperature changes across the continental United States.
The largest gap between any of the datasets in any year was 0.38ºF (0.21ºC), and the smallest gap was 0ºF/C: * To reconstruct global average temperatures in the era before instrumental measurements were made on a global scale, scientists use proxies that respond to changes in climate, such as the widths of tree rings and certain elements of the geological record, to estimate temperature variations in the past.  * The Intergovernmental Panel on Climate Change (IPCC) is a scientific body established in 1988 by the United Nations and World Meteorological Organization.
PPT engineers have been involved in flexographic press design since 1979 providing Cobden Chadwick with a successful major core product in the 1980's and 1990's.
Since 2002, PPT has been supporting its pre-print customers, offering comprehensive service & support, a range of upgrades, new printing sections for integration with existing press lines and complete presses to satisfy the ever increasing demand for pre-print globally. section, which operates by means of linear motor technology, therefore eliminating the need for conventional ballscrews, timing belt transmissions, stepping motors and on press hydraulics.
Don’t take it wrong, carbon indeed has its merits, but the recent carbon craze seems to be heavily tied to bandwagon mentality; whatever the pros are doing is what the masses want to do too.
It was true in the ‘70s with drilled-out components, in the ‘80s with copious amounts of hair gel and Briko shades, in the ‘90s with those horrific lycra shorts designed to look like blue jeans, and today with carbon racing bikes. A frame and fork weighs less than a six-pack of brew, they’ve got terrific road damping capabilities, are stiffer than an I-beam – at least initially – and most importantly, carbon fiber has an indisputable cool factor.
