INTRODUCTION AND HISTORY:
What is Global Warming?
Global warming is the rise in the average temperature of Earth's atmosphere and oceans since the late 19th century and its projected continuation. Since the early 20th century, Earth's mean surface temperature has increased by about 0.8 °C (1.4 °F), with about two-thirds of the increase occurring since 1980.
Facts to be remembered:
Our planet is warming up, and not in a good way! The last 20 years were the hottest in 400 years, according to several studies. An upsurge in the amount of extreme weather events, such as wildfires, heat waves, and strong tropical storms, is also attributed in part to climate change by some experts.
Between 1970 and 2004, global greenhouse gases (GHGs) have increased 70 per cent due to human activities. You don’t have to be an environmentalist to know that’s a massive jump in pollutants and a big problem for the effect it has on the planet’s natural temperature. It’s even worse for carbon dioxide; its annual emissions grew by about 80 per cent between the same periods. Our society is pouring carbon dioxide into the atmosphere much faster than plants and oceans can absorb it.
What is Climate Change?
Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years. It may be a change in average weather conditions, or in the distribution of weather around
