8 Negative Effects of Climate Change
601Negative effects of climate change! Global warming is a change in weather patterns, which affects nature & makes sea levels rise. Here are scientists' explanations of what climate change can cause.

8: Destruction of archeological sites
We often think about how changes in the climate are threatening the lives of humans, animals, & plants on the planet. But we fail to realize that it's not only the living that are affected by climate change. In fact, archeological sites - priceless windows to our past - are suffering as well. High sea waves are hitting Easter Island, the famous site of the moai - mysterious giant head-and-torso statues built by ancient Polynesians.
7: Food shortages
We've mentioned how climate change & global warming leads to drought, deforestation, & pest infestation. All of this combined causes one major problem - it inhibits the ability of farmers to grow food. In order to grow, crops need to be on fertile land, which becomes largely unavailable due to water shortages. Food shortages have not occurred widely yet, & international trade will likely prevent any major famine to affect us soon - at least not in the near future.
6: Rising CO2 levels
Since the Industrial Revolution over 2 centuries ago, we've gradually been producing more & more Carbon Dioxide on a regular basis. With large scale industrialization & the burning of fossil fuels, we've put a total of 2000 gigatons of CO2 in the atmosphere, & about 40% of it has stayed there. Humans have only been roaming this planet for a relatively short period, yet today's CO2 levels are the highest they have ever been for millions of years.
5: Global Warming
Global warming - it is the main form of climate changing, & the 2 terms are even often used interchangeably. As of right now, the Earth is warming at a scary rate, 10 times faster than at the end of the Ice Age. Since we started measuring global surface temperature in 1850, each decade seems to surpass the previous, & that rate does not seem to be slowing down. This directly affects us in a number of ways, mainly in the form of drought & extreme weathers. Since the previous century, mega droughts have been appearing everywhere all over the Earth.
4: Losing our forests
Climate change affects all life on the planet, & this includes forest ecosystems, many of which have been destroyed indirectly by global warming. Bark beetles are major pests that feed & breed between the bark & wood of various tree species, damaging them in the process. These insects thrive in warm temperatures, & as a consequence of global warming, have expanded their ranges & proliferated widely in the forests of North America & Europe. Millions of acres of forest have been destroyed due to bark beetle infestation in recent years.
3: Insufficient energy to meet demands
Since the dawn of mankind, people have learnt of various ways to keep themselves warm - from starting simple fires to creating electric-powered heaters. One of the main reasons for energy demand used to be heating, as people needed to survive long & chilly winters. But a global trend that started in the past century has seen a reversal, especially with the invention of cooling devices like refrigerators & air conditioners. With the climate getting warmer & warmer, the demand for cooling has skyrocketed. With the increase in carbon emissions & the resulting hot temperatures, the demand for more energy to produce cooling is getting out of control.
2: Melting ice caps & rising sea levels
Water covers more than 70% of our planet, & they absorb most of the heat added to the atmosphere. So it's only natural that is where the extreme changes of climate change are seen. Sea levels around the world have been rising a 10th of an inch every year, & they're already up 8 inches since 100 years ago. There are 2 reasons for this. 1 water expands as it gets warmer. 2, because glaciers, ice caps & icebergs are melting, so they add up to the ocean's water volume. White sea ice is essential in reflecting sun rays back up into the atmosphere.
1: Animal extinction
A lot of animals, mostly birds, are seen beginning their seasonal migrations a lot earlier. For instance, scientists have found that the Icelandic black-tailed godwits have started migrating 2 weeks earlier than normal to escape the summer heat. The distribution patterns of Adelie penguins across Antarctica have also changed significantly. They are known to mainly feed on Antarctic krills, which are small crustaceans that stay under ice caps. The melting of polar ice in the summer has led to Polar bears channel arising their own cubs out of desperation in order to stay alive. With more Carbon Dioxide released into the atmosphere, more of it ends up dissolving into the ocean, causing a decrease in the water's pH levels.
