climate change - what to do or not to do?
I read in Wikipedia: "Currently, the Earth is in an icehouse climate state. About 34 million years ago, ice sheets began to form in Antarctica ; the ice sheets in the Arctic did not start forming until 2 million years ago. [5] Some processes that may have led to our current icehouse may be connected to the development of the Himalayan Mountains and the opening of the Drake Passage between South America and Antarctica. Scientists have been attempting to compare the past transitions between icehouse and greenhouse, and vice versa to understand where our planet is now heading. Without the human influence on the greenhouse gas concentration, the Earth would be heading toward a glacial period. Predicted changes in orbital forcing suggest that in absence of human-made global warming the next glacial period would begin at least 50,000 years from now [ (see Milankovitch cycles ). But due to the ongoing anthropogenic greenhouse gas emissions, the Earth is instead hea
