Global Warming - True Crisis or Pure Hype?
Weve been hearing the warnings of global warming problems for quite some time now. The push is on to promote green living to help save the environment and stop some of the effects of global warming.
Global Warming: The Bio Fuel solution
The recent furore over the Kyoto protocol pertaining to global climate change, as well as the rising prices of fossil fuels has led India and other developing countries to look for an ecological and economically viable alternative. Several initiatives have been taken in recent times on the energy front such as large scale promotion of wind energy farms for power generation, blending of ethyl alcohol with petrol and developmental efforts towards bio fuels. Impressed by the potential of Jatropha curcas, the Government of India and the Planning Commission have been looking at the opportunity carefully. Several reports have been prepared and organizations such as the Indian Oil Corporation and Indian Railways, as well as several universities a...
Discovery Survey Finds Global Warming the Most Pressing Need
Western Australians believe discoveries to help solve global warming and climate change are the most urgently needed.
Stop Global Warming. Individual Actions That Everyone Can Take to Support the Environment
As the government and manufacturers throughout the world continue (and in some cases resist) to do their part when it comes to creating more eco-smart and friendly products the next step is for the consumers to begin making smarting choices during their shopping
The problem with many of these new eco-friendly products is they are often more expensive than the regular products and as the economy is not stable today it can be hard to afford the right products even if you wanted to

National Coatings AcryShield Roof Coatings Fight Global Warming
Last year alone, the cool-roof coating materials manufactured by National Coatings under the AcryShield label helped avoid as many as 24 million pounds of CO2 being produced due to reduced demands for energy.
Infrared thermometers (http://www.infraredthermometry.com/) and temperature sensors, such as the AGRI-THERM II (http://www.everestinterscience.com/products/model6110/6110.4ZL.htm) manufactured by Everest Interscience (http://www.everestinterscience.com/) have been used for a few decades now to measure the surface temperature of crop canopies and individual leaves in agronomic applications for the natural environmental sciences (http://www.everestinterscience.com/products/app/natural.htm). This work has been done primarily for agricultural applications to determine optimum irrigation scheduling and conservation of water. Much work has been done by researchers in universities and federal facilities and in many foreign countries on such theories as the Crop Water Stress Index http://www.hydrology1.nmsu.edu/Teaching_Material/soil698/cwsi.html(CWSI) and Stress Degree Day (SDD) (http://www.books.google.com/books?id=NUcoZNPMQEEC&pg=PA438&lpg=PA438&dq=%22Stress+Degree+Day%22&source=web&ots=5V1LOQnbSD&sig=kL8mw4s0kVlsqc4qeKpTavBqiVc&hl=en) concepts. However, one important concept has often been overlooked in these studies. That is the effect of sky radiation and the employment of a means to compensate for the reflection of the sky from plants or other objects that the infrared thermometer is measuring.
The unique solution of the phenomenon of sky radiation is the addition of the Everest Interscience ?Sky-Spy? to the infrared thermometer or temperature sensor. The Sky-Spy ?? provides a novel means for sensing the level of infrared radiation received by the vegetation from a skyward direction,? according to Everest?s U. S. Patent No. 4,420,265. With this invention, a second detector is utilized wherein the reflection by the vegetation received from a skyward direction may be taken into account to measure the actual surface temperature of the plant. The purpose of this second sensor is to account for reflected sky radiation characteristics and compensate for them in the temperature reading from the plant itself in order to produce a more precise infrared measurement.
In order to explain the inaccuracies that can be derived by measuring the vegetation without the use of a ?Sky-Spy,? assume that the leaf that is being measured is a first surface mirror and that the temperature reflected by that mirror is the temperature of the radiation from the sky. This temperature could be as much as -80°C under clear sky conditions. Then, assume that the mirror affect is fading into the leaf and the mirror radiation comprises only two (2.0) percent of the total radiation (Surface Emissivity = 0.98) and the leaf forms 98%. The secondary mirror radiation, or the temperature of the sky radiation reflected on the secondary mirror, is now only two (2.0) percent of the temperature of the radiation or -1.6°C. The temperature of a leaf is usually in a range of no more than minus ten degrees compared to the surrounding ambient air. So, the -1.6°C could be sixteen (16) percent of the total or as much as -1.6°C, bringing the effective temperature of the leaf down by that amount. In a science where accuracies of ?0.5°C are desired, this error is intolerable.
Of course, at low elevation conditions, perhaps in the presence of high water vapor and CO2 layers, the apparent sky temperature is much warmer than -80°C. Under these conditions, the Sky Spy instantly and automatically corrects for all sky temperatures from ambient to -100°C or beyond
This unique Sky-Spy, coupled with the infrared thermometers for making SDD and CWSI measurements for irrigation purposes that is covered in Everest?s U. S. Patent No. 4,301,682, provide a more accurate means of making the precise temperature measurements needed for CWSI application. One such infrared thermometer is Everest?s AGRI-THERM II.
The AGRI-THERM II has been used extensively worldwide to measure crop canopy temperatures in an attempt to control irrigation with the goal of improving crop yields while reducing the amount of irrigation needed. More information on this subject can be read in M. B. Kirkham?s book, Principles of Soil and Plant Water Relations, 2004.
The AGRI-THERM II infrared thermometers are capable of taking surface temperature measurements in a highly dynamic environment such as having the thermometer taken from an air conditioned truck into the heat of the desert without giving them time for equilibration before taking the measurements. Under these environmental conditions, they respond with accuracy of ?0.5 degrees C or ?1.0 degree F.
Everest also markets an infrared temperature sensor, the Model 4000.4ZL (http://www.everestinterscience.com/products/model4000/4000.4ZL.htm), infrared temperature sensors that can be mounted in the field and run continuously. And, the Model 6000 (http://www.everestinterscience.com/products/model6000/6000.1ZL.htm) miniature infrared temperature sensors can be used for the same purpose but also include unique Vario-Zooom (http://www.everestinterscience.com/capabilities/ttl.htm)and TTL/SLR (http://www.everestinterscience.com/products/app/ttl.htm) features. The Vario-Zooom provides a field-focusable infrared temperature sensor with Intra-Optical Light Sighting provided by the TTL/SLR, Through-The-Lens/Single Lens Reflex system (U. S. Patent Nos. 7,355,178 and 4,477,814).
