Global warming " refers to rising global temperatures, also it is a planet wide. while “climate change” includes other more specific kinds of changes, too. Warmer global temperatures in the atmosphere and oceans leads to climate changes affecting rainfall patterns, storms and droughts, growing seasons, humidity, and sea level. climate change ” refer to changes at the global, continental, regional and local levels. Even though a warming trend is global, different areas around the world will experience different specific changes in their climates, which will have unique impacts on their local plants, animals and people. A few areas might even get cooler rather than warmer.
An analysis of 30 years weather balloon data have shown that the air over Antarctica is warming even faster than in other parts of the world . The weather balloon data show a warming of 0.9 degree to 1.3 degree Fahrenheit per decade over the last 30 years By contrast, the average worldwide temperature has risen 0.2 degree per decade in that time.
What is weather balloon weather balloon used in the measurement and evaluation of mostly upper atmospheric conditions Information may be gathered during the vertical ascent of the balloon through the atmosphere or during its motions once it has reached a predetermined maximum altitude. Today, atmospheric information is most often gathered by height-finding radar, remote sensing by earth-orbiting or stationary satellites, and aircraft instruments, with weather balloons augmenting the data. Helium, which is less dense than air buoyancy, is usually used to inflate weather balloons. A pilot balloon is a small balloon (diameter c.1 m/39 in.) whose ascent is followed visually to obtain data for the computation of the speed and direction of winds at different altitudes. A smaller ceiling balloon is used to determine the altitude of cloud bases. A much larger, teardrop-shaped

Reduced ability of Ecosystem to Absorb Greenhouse Gases
Deforestation is a contributor to global climate change and is often cited as one of the major causes of the enhanced greenhouse effect .Tropical deforestation is responsible for approximately 20% of world greenhouse gas emissions. According to the Intergovernmental Panel on Climate Change deforestation, mainly in tropical areas, account for up to one-third of total anthropogenic carbon dioxide emissions, Trees and other plants remove carbon (in the form of carbon dioxide) from the atmosphere during the process of photosynthesis and release it back into the atmosphere during normal respiration. Only when actively growing can a tree or forest remove carbon over an annual or longer timeframe. Both the decay and burning of wood releases much of this stored carbon back to the atmosphere. In order for forests to take up carbon, the wood must be harvested and turned into long-lived products and trees must be re-planted. Deforestation may cause carbon stores held in soil to be released. Forests are stores of carbon and can be either sinks or sources depending upon environmental circumstances. Mature forests alternate between being net sinks and net sources of carbon dioxide (see carbon dioxide sink and carbon cycle

Global Responses to Climate Change KYOTO PROTOCOL ADOPTED BY 10,000 DELEGATES IN KYOTO, JAPAN -- ENTERED INTO FORCE In FEBRUARY 2004 PRESENTLY, 169 COUNTRIES HAVE RATIFIED THE PROTOCOL -- PROVIDE FOR CLEARER AND BIGGER TARGET OF 5% REDUCTION IN GREENHOUSE GAS EMISSIONS BY DEVELOPED COUNTRIES BY 2012 -- NO REDUCTION REQUIREMENT FOR DEVELOPING COUNTRIES Pie Chart Pie Chart
T he Kyoto Protocol calls for mandatory carbon dioxide reductions of 30% from developed countries like the U.S. Reducing man-made CO2 emissions this much would have an undetectable effect on climate while having a devastating effect on the U.S. economy. Such drastic measures, even if imposed equally on all countries around the world, would reduce total human greenhouse contributions from CO2 by about 0.035% . This is much less than the natural variability of Earth's climate system! While the greenhouse reductions would exact a high human price, in terms of sacrifices to our standard of living, they would yield statistically negligible results in terms of measurable impacts to climate change. There is no expectation that any statistically significant global warming reductions would come from the Kyoto Protocol.
Addressing climate change through the implementation of all possible measures The first commitment period of the Kyoto Protocol began in 2008 and the Fujifilm Group, with operations worldwide, is proactively addressing the issues of climate change. We are promoting activities to prevent global warming from a medium- to long-term perspective based on national and international laws and regulations as well as related industry regulations. We were among the first to make capital investments and pursue alternative energies. Focused on domestic facilities where emissions are concentrated, we have achieved significant CO 2 reductions. Looking ahead, we will continue to reduce CO 2 emissions, setting clear targets and ultimately cut energy intensity by 30% from levels in fiscal 1990 and lower CO 2 emissions intensity by 40% in fiscal 2012 for our six major domestic chemical factories(*1). In particular, we will draw upon our experience in implementing a variety of measures to help prevent global warming in light of the rise in CO 2 emissions as a result of increased production volumes in new businesses, including flat panel display materials, as well as overseas business development and expansion .

The Philippines has not been spared of the weather-related disturbances and disasters. The past typhoons have been unusually heavy and have brought devastation to our country and our people.
Storm Surge is an offshore rise of water associated with a low pressure weather system, typically a tropical cyclone. Storm surge is caused primarily by high winds pushing on the ocean 's surface. The wind causes the water to pile up higher than the ordinary sea level.
