There is certainly evidence to suggest that global warming is a real issue, not just an urban myth. Since pre-industrial times (I. E. Before the industrial revolution in the late 1 dos) global average temperatures have risen by about 0. ICC, with roughly half of this occurring in the past 30-40 years. Not only this but carbon dioxide levels in the Earth’s atmosphere have also dramatically increased since this time.

But is this relatively recent rise in global temperatures down to human activities or is it just a result of the planet’s ore temperatures naturally fluctuating up and down, like they always have, or is it a combination of both? The majority belief, particularly in the past few decades, is that climate change is solely a result of human activities putting a huge strain on the planet and it is these man-made issues that probably cause the most damage. Pollution is perhaps the biggest anthropogenic problem in terms of climate change and can come in many forms.

A large Plan The case for attributing the recent global warming to human activities rests n the following undisputed scientific facts: ; Carbon dioxide (CO) is a greenhouse gas that warms the atmosphere. ; Since pre-industrial times, atmospheric CO concentrations have increased from about 280 parts per million (pimp) to over 380 pimp. Current concentrations of CO and other greenhouse gases are unprecedented in at least the last 650,000 years, based on records from gas bubbles trapped in polar ice. Independent measurements demonstrate that the increased CO in the atmosphere comes from burning fossil fuels and forests. The isotopic composition of carbon from these sources contains a unique “fingerprint.
