To what extent is human activity responsible for changing climate?
....Carbon dioxide (CO2) has increased by 35% over the last 150 years. However, it’s (contribution) is only minute compared to natural causes. The Intergovernmental Panel on Climate Change (IPCC) is 90-99% sure that the cause of 20th century warming is human activity. Many, including me, disagree. We believe causes are natural.
Who can we say is right?
Look at the evidence. Data does not support IPCC. Water vapour is a greenhouse gas (GHG) and is much stronger than CO2. But IPCC dose not consider water vapour explicitly. We believe water vapour decreases the effect of CO2.....
Why then is CO2 portrayed as the chief culprit of climate change?
...For political reasons, people talk only about CO2 as it’s emitted due to industrial factors, while CH4 is due to grazing.
How much of a bearing does the sun have on climate?
In 1700, sun spots disappeared and temperature on earth became low, ice formed. In EU, there were cold summers, very cold winters, and no vegetation, leading to famine. Several people died from diseases. 1,000 years ago, there was medieval warming, leading to crops forming at the southern tip of Greenland. The sun caused it....
There is strong apprehension that sea levels would increase tremendously.
An 18 cm rise in the sea level per century has been the norm for over 3,000 years and this will continue, no matter what.
There is also apprehension that small islands would drown due to climate change?
Many small islands are made out of coral which keeps up with the sea level. If the sea rises, coral grows and it never gets buried by the sea.
So what is Copenhagen all about then?
Oh it’s a political event. ... Schemes to control CO2 will make energy expensive. Emission cuts make energy very expensive, which only the rich can afford. You know, total emissions of CO2 have gone up in US, EU. In 1997, during the Kyoto Protocol, they promised to reduce emission by 5%. But emission is only going up. They have no intention of reducing it.
Copenhagen is a very bad idea....
So should the common man worry about climate?
No need for any worry. Climate is not a problem. It’s crazy to think that human activity can impact global climate....
