My speech is about what makes me concerned. Well my answer is Global Warming. Global warming refers to the increase in the average temperature of the Earth’s near-surface air and oceans in recent decades and its projected and its projected continuation. The Earth’s climate changes in response to external forcing, including variations in its orbit around the sun (orbiting force), volcanic eruptions, and atmospheric greenhouse gas concentrations.
The greenhouse effect was discovered by Joseph Fourier in 1824 and was first investigated quantitatively by Svante Arrhenius in 1896. It is the process by which absorption and emission of infrared radiation by atmospheric gases warms a planet’s atmosphere and surface. The temperatures will rise and snow will be a thing of the past. Kevin Rudd has signed and is trying to ratify the Kyoto Protocol. The only countries who haven’t signed the Kyoto Protocol are United States and
Kazakhstan.
If Global Warming isn’t stopped, then all coastal cities will be flooded. Global Warming affects me pretty dramatically because I always wanted to live a peaceful and happy life. This may not happen. To help stop Global Warming you can use an Energy Efficient light bulb. Thank you for listening to my speech. J
