Do you ever feel like you know just enough about global warming to be dangerous? Let’s see if we can fill in some of the gaps with the latest info from real global warming experts.
Scientists, together with us environmentalists, are constantly warning politicians that time is running up but that doesn’t seem to bother them, especially now in times of recession. Revive economy or save the planet? Scientists and economists can agree with Buddhist monks and Christian activists that ruthless destruction of natural habitats is evil and careful preservation of birds and butterflies is good. The worldwide community of environmentalists-most of whom are not scientists-holds the moral high ground, and is guiding human societies toward a hopeful future. Scientists are human; they do not wait for proof. Many devote their professional lives to seeking evidence for hypotheses, especially well-funded hypotheses, they’ve chosen to believe.
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.
Global warming is one of the most hotly debated issues today. Cars have been identified as one of the leading contributors to the escalating global warming problem. Global warming is a huge risk. We’re not just talking about retiring our winter coats in favour of lighter jackets. Global warming is one of those era-defining issues for which perception is reality. And if that perception shifts-and it could shift quickly-the economic impact on energy companies will be swift and lasting.
Global warming had changed their habitat, so to speak. Global warming, as you may already know is the process that describes the earth’s temperature rise. This rise in temperature is because of greenhouse grasses. Global warming and climate change are the biggest problem we are facing today well at least this is what scientists say. There are of course still some that do not believe in global warming and they look at it like some crazy invented thing made by Al Gore and other scientists.
So now you know a little bit about global warming causes. Even if you don’t know everything, you’ve done something worthwhile: you’ve expanded your knowledge.
