Global Warming vs Natural Climate Change
Do you ever feel like you know just enough about global warming but not sure if it’s just natural climate change? Let’s see if we can fill in some of the gaps with the latest info from real global warming experts.
Climate simply refers to one day of weather after another. Global-warming true believers ask: Do you view weather forecast projections for 2 weeks from today with the same certainty that you do a computer model that purports to predict the weather 100 years from now?
Temperatures were high at that time due to the peculiarities of the Earth’s orbit. During the Pliocene (2-5Ma) before the Quaternary ice age began, temperatures were also significantly warmer than today. Temperatures have steadily increased at around a quarter of a degree for every 1,000 years. During the last 100 years temperatures have increased by twice that amount.
Think about what you’ve read so far. Does it reinforce what you already know about global warming causes? Or was there something completely new? What about the remaining paragraphs?
Human activities have altered the chemical composition of the atmosphere through the build-up of greenhouse gases – primarily carbon dioxide, methane, and nitrous oxide. The heat-trapping property of these gases is undisputed although uncertainties exist about exactly how earth’s climate responds to them. Humans measure warmth as temperature which is a measure of the amount of heat contained in a physical object. One can envision this concept by thinking of a pot on a stove.
Environmental policies have particularly been difficult to implement because they have historically conflicted with economic goals and the performance evaluations of local officials were tied to GDP targets rather than environmental performance. This appears to be changing energy conservation, is now a pillar economic strategy and, from what I understand, has become a key metric in the promotion evaluations of local officials. Environmentalists claimed the number of scientists supporting the measure was “overwhelming”. That never was true.
Greenhouse gases trap heat energy trying to escape from the planet’s atmosphere. It normally goes out through virtual windows, which are becoming plugged. Greenhouse experiments show that many plants growing in an atmosphere enriched with carbon dioxide react by increasing their root-to-shoot ratio. This means that the plants put more of their growth into roots and less into stems and leaves.
I hope that reading the above information about real global warming issues was both enjoyable and educational for you. Your learning process should be ongoing–the more you understand about any subject, the more you will be able to share with others.
