Global warming

"It says here that by 2075, the Earth's oceans will be too warm to sustain most coral reefs, and once they're gone, the entire ecosystem of the planet will collapse."

- Malcolm Barrett, when reading a newspaper.

Global warming is an event in which the average temperature of the planet increases to a point where a planet's ecosystem will collapse. Due to the extent on burning fossil fuels on Earth, the planet is experiencing the events of global warming.

M44-5YN, a planet in Pegasus is experiencing the effects of naturally occuring global warming, which a team lead by Dr. Nichol investigated, until the one of the planet's glaciers breached, causing severe flooding on the valley which was the location of the planet's Stargate.
