Recently, President Trump removed the United States of America from the Paris Accord, dealing a critical blow to environmentalists. President Trump has never been a firm believer in climate change, citing it as an "expensive hoax" created by the Chinese in order to make US manufacturing non-competitive.
However, global warming is a very real problem that we are facing today. Rising sea levels could threaten life in coastal towns; the biodiversity of our planet is at an extreme risk, all proving that global warming is a problem that we need to solve as a species brings us a step closer to eradicating it.
1. Rising sea levels
According to reports, the sea levels are rising at an unprecedented rate and have risen 7 inches in the last 100 years, more than it has in the last 2000 years combined. This rise can be attributed to increasing global temperatures. Both thermal expansion, the expansion of water when temperatures increase, and the melting of the polar ice caps add to the rising sea levels as well.
2. Average temperature
Maybe you've noticed that it's a little warmer outside than it usually is. You're right. The average temperature has risen by 1.4 degrees Fahrenheit, making our modern-day world hotter than it has ever been.
3. Arctic ice
The sea level are rising, and part of the reason is the melting of the polar ice caps. It is estimated that by the year 2040, the ice caps will be completely melted during the summers. This is catastrophic for the many animals who live in the arctic, as their habitats will be destroyed.
4. Coral reefs
Perhaps you have heard about the death of Australia's Great Barrier Reef. Coral reefs are one of the most delicate ecosystems in the world, and the rising temperatures are bleaching the corals, killing them. Coral reefs are equitable to the rainforests of the terrestrial world, and the sheer amount of biodiversity is incredible, so their destruction leads to massive numbers of species going extinct.
5. Extinctionslocal extinctions, or extinctions limited to the area they were previously found in, due to climate change. Unsurprisingly, the tropics were hit the hardest by global warming, as their temperatures usually remain quite steady during the year.
This past decade has been declared the hottest in record, and 2016 was called the hottest year in record as well. Sixteen of the past seventeen years have been the hottest years on record.
The increasing temperatures linked to global warming have also led to widespread food and water shortages. Global warming is expected to account for 20% of the global increase in water shortages this century. These water shortages in turn lead to food shortages, as agriculture and the meat industry both require water to keep their produce alive.
