GLOBAL WARMMING!!

[|global warming] = ﻿What is global = = warming? = =The earths climate is changing habitats and wildlife across the plannet. The evidence shows that human activities--like burning fossil fuels like coal,oil and gas--are most likely responsible for the warming observed to date. And the trend is clear. If we dont take steps to curb global warming pollution,the impacts will become increasingly dire. =

The Earth's atmosphere has already warmed by 1.5 degrees Fahrenheit since 1900. This warming signal is also found in ocean temperatures, soil temperatures, melting glaciers and melting polar ice caps. It has been linked to widespread impacts on ecosystems around the planet. This preponderance of evidence all points to the conclusion that our planet is warming and natural systems are struggling to keep up. SOLAR AID

The poor communities use kerosene for lighting which is highly toxic. Solar Aid is a project helping Kenya, Zamba, Malawi,Tanzania and many more. Solar Aid creates a clean,safe sustainable way out of poverty, replaces harmful kerosene with solar powered LED bulbs. The solar PV system provides solar energy in schools, clinics, community centers and much more.

Natural warming The greenhouse effect is a natural warming process. Carbon dioxide (CO 2 ) and certain other gases are always present in the atmosphere. These gases create a warming effect that has some similarity to the warming inside a greenhouse, hence the name “greenhouse effect”.

Causes of global warming The major causes of climate change are described in the following section.  · CO 2 and other Greenhouse Gas Variations  · Human Activity and Greenhouse Gas  · Reducing Other Greenhouse Gases  · Ocean Circulation  · Solar Variations media type="custom" key="9006456" align="center"

Information on global warming Very small different in clouds may produce large feedbacks. An increase in high, thin clouds produced by greenhouse warming would further increase the warming. This is because high, thin clouds are relatively effective in trapping infrared radiation (heat) while allowing the Sun’s energy to pass through. In contrast, an increase in thick, low clouds could lessen the warming because these clouds reflect sunlight efficiently. My thoughts on global warming If global warming was to occur there IS IT HAPPENING? Yes, Earth is already showing many signs of worldwide climate change. · Average temperatures have climbed 1.4 degrees Fahrenheit (0.8 degrees Celsius) around the world since 1880, much of this in recent decades, according to NASA’s Goddard Institution for Space Studies. · The rate of warming is increasing the 20th century’s last two decades were the hottest in 400 years and possibly the warmest for several millennia, according to a number of climate studies. And the United Nations.

This energy is very powerful and hits the earth regardless of whether or not we take advantage of it. Even the tiny percentage of sunlight that touches the earth is plenty to meet the energy and power needs of the entire human population more than 8,500 times over. <span style="color: #76923c; display: block; font-family: 'Comic Sans MS'; font-size: 16pt; line-height: 115%; margin: 0in 0in 10pt; tab-stops: 56.25pt; tabstops: 56.25pt; text-align: center;">The only concern is learning how to collect, this energy efficiently, today there are many different technologies which exist to achieve this goal. Due to concerns of the availability of traditional energy sources, many people today are interested in further developing renewable energy technologies, such as solar devices. <span style="color: red; display: block; font-family: 'Comic Sans MS'; font-size: 16pt; line-height: 115%; margin: 0in 0in 10pt; tab-stops: 56.25pt; tabstops: 56.25pt; text-align: center;">For this reason it is sensible to expect continual improvement of existing solar technology and the invention of new solar power devices over next few decades.
