Question
Pilar l: theory 1. The sun is controlling the climate not CO. 2. There is no evidence that COz has any control on climate. 3. We can't even predict the weather two weeks ahead, so we can certainly not predict it for a 100yrs into the future IPCC is alarmist: Published climate sensitivity estimates are decreasing with time, converging to zero. 4. source:link Pilar Il: Observed CO2 changes 1. CO2 has been changing all the time. Today's changes are not significant. 2. Natural CO emissions are much larger than human COz emissions. PilarI: Observed climate change 1. Data is incorrect. The earth is not warming. 2. The data is manipulated in many ways to make it look as if it is warming. 3. Temperatures are decreasing even though CO2 is increasing. 4. The earth has not warmed over the last 20yrs source:> link Pilar IV: Alternative causes 1. It is the sun. 2. It is internal natural variability that happens all the time. Pilar V: Impact 1. 3 degrees warming happens all the time, has happened before and therefore it will not have an impact. We can easily adapt. Adaptation is cheaper than mitigation (prevent it from happening). 2. 3.Explanation / Answer
pillar 1-----sun is controlling the climate and not carbon di oxide----
The sun being the largest source of energy for the universe ,because of this life sustains on the planet.
without sun there will be no life , from humans to plant life to animal life all survive on the support system from the sun.On the other hand ,carbon di oxide is one of the basic end product of the burning of fossile fuels.,like paper , plastic, leaves ,tabacco, industries etc all emites carbon dioxide.Carbon dioxide is considered relatively innocuous because it has no direct effect on health. but it has several important sideeffects.It contributes towards acid rain and green house effects.
climate means the average pattern in which weather varies in time.the climate of a region depends upon the presence or absence of water, solar radiation,or albedo, evaporation the capacity to store heat and topographyof the region.moreover, the pollution blanket influences the climate of the region.this includes the biological heat realeased by the city population, industries etc.other factors are accerlerated run off of precipitation instead of absorption and evaporation , altered albedo and heat storage capacity.these results from replacing forests and fields with concrete buildings and humans thus exert a dramatic influence on local climates. nothing works in isolation , when every thing is interrelated.from solar system to human activity. every action will witness a reaction.to say that only one is reflected in the change by the climatic scincetist is very strange.the earth has witnessed many changes of climate from ice era to warm green house effects.and at each era drastic changes has been wittnessed by humans.
3)we cannot predict the weather of two weeks, so we cannot predect it over 100 years....-----
There are limitations for everthing ,and humans have to face the challenges at every step. To an extend we cannot predect the future but due to development in satilite studies this is not 100% exceptable.We can study and predict the weather with the help of satilite images and many other devices, which gives us basic understanding of the changing weather conditions in future.By studying the changing conditions all around the world with fauna and flora we can understand the changes of weather .climatic scientist predictions made in the 1970's about climate change through this decade have proven accurate enough for government policy, business planning and personal choices to be based on.Predicition and accuracy are different things , to be accurate in our study over a period of time and to predict the accurate future ,we can have accurate study at present time which will help us to understand the closeness in our reseach.As the out comes could be severe due environmental changes , so it becomes very important to study and pridect the future of climate. some time it is difficult to reverse the changes, or to go back , so weather scincetists are too accurate or not it is important to study for our better futures , and timely taken actions.

co2 has been changing all the time todays change is not siginifant----(against the thought)
today the carbon cycle is changing ,it is increasing every year.more carbon is moving into the atmosphere due to burning of fossile fuel and deforestation.carbon is accumulates in the atmosphere in molucular form , which absorbs heat ,and in turn effects the temperature of the earth.carbon di oxide remains in the atmosphere for a long time upto centuries , so even if people stop adding carbon to the atmpshere now it will continue to remain warm.the carbon can slowly move back into the biosphere , taken up by plants as photosynthsis . it can also store into the ocean rocks of the geosphere like limestone.researchers are studying these processes and others that move carbon out of the atmosphere.The carbon cycle has changed over billion of years of earth history .however prehistoric changes happened for different reasons.The amount of carbon dioxide in the earyhs atmosphere increased at times in the past during the Devonian period of the Paleozoic for eg; because of volcanic eruptions.valcanoes released more gases. but at present times it is due to forest cuttings , industries and burning of fossile fuels.
natural co2 in higher than human emmisions------
human co2 is a tiny emmisions.The ocean contains 37400billion tons of suspended carbon and land biomass has 2000-3000GT.The atmosphere contains 720 billion tons of co2 and humans contributes only 6 GT additional load which is very small.Before the industrial revolution, the co2 content in the air remained quite steadyfor thousands of years.Natural co2 is not static , however it is generated by a natural process and absorbed by others. but when more co2 is realeased from out side of the natural carbon cycle- by burning fossile fuels.Although our output of 29 gigatons of co2 is tiny compared to the 750gigatons moving through the carbon cycle each year, it add up because the land and ocean cannot absorb all the extra co2.About 40% of the co2 is absorbed rest remains in the atmosphere.as a result atmospheric co2 is at its heighestlevel in 15 to 20 million years.human co2 emmision upsets the natural balanceof the carbon cycle.man made co2 has increased immensily since the industrial revolution, creating an artificial forcing of global temperates , which is warming the planet.while fossile fuel derived co2 is a very small component of the global carbon cycle,the extra co2 is cumulative becausre the natural carbon exchange cannot be absorbed all the additional co2. excessive burning of fossile fuel adds more co2 in to the atmosphere.
