Facts About Global Warming

can you pls compare greenhouse effect and global warming?

i wanted to know what is the difference between greenhouse effect and global warming. And pls compare them both

As a geologist, I am well aware of the effects of warming and cooling. Our climate is not static as many alarmist seem to imply. It changes all the time though on time scales of thousands of years. For the last several thousand years, we have been coming out of a glacial period and are in an interglacial period. These glacial and interglacial periods have been happening at regular intervals for over two million years due primarily to continental drift setting up the conditions and from cycles in our orbit, our axis or rotation know as the Milankovitch cycle

During this cycle warm periods theoretically result in the release of CO2 in the oceans since CO2 is less soluable in warm water. Also limestone is less soluable in warm water so calcite precipitation will also increase but that is a separate issue. CO2 is a greenhouse gas but its effects are small when compared to water vapor. Since the increasing CO2 was not previously demonstrated to be responsible for warming there is no good evidence that the increased CO2 is why it has warmed. The alarmists think of many excuses and reasons but they have not adequately explained why if CO2 is main driver in temperature why it was colder in the 1970s and certainly not the previous cold periods. In my opinion, the theories about about CO2 causing feed back are far fetched and probably are from Wesley Striebers, a fiction author, theory that warming will substantially release methane hydrate known to exist on the ocean floor causing an out of control warming trend.
