A Brief Update on Climate Change

It is 2050. Imagine waking up in an oxygen-filled, glass chamber. You step outside and everything insight is in a grey hue. Greenery now exists only in the pages of history books. This is how sci-fi movies generally portray the impending future. Before you stress yourself out, let me tell you that we are yet to fall in such a state. However, things do not look so good either.

Over the last century, the average surface temperature of the Earth has increased by about 1.0 degrees Fahrenheit. Looking back to about 20,000 years ago the sea level was about 120 meters lower than today because of more water being frozen into polar ice sheets. But in the last 8,000 years (which has been described as the most recorded human history), the temperature has stabled at the warmer end of the scale and is still going. This temperature stability is a result of agriculture, permanent settlements, desertification, and population growth. Continuing to the situation the future under climate change can seem frighteningly vague and variable.

Fast forward to 2050. The Earth's surface temperature has surpassed 2°c from that of the past century’s. In the same period, the global sea level has risen by another foot. The Arctic is now ice-free in summer. The marine mammal, fish, and bird populations are all changing. Despite the frightening prophecy of the future earth, there is still a chance for redemption. According to a climate science body, the best path to limiting warming is by cutting net human carbon dioxide emissions by 45% within 2030, and following this after 12 years the amount of cutting emissions further to net-zero by 2050.

There is some superhuman who took a stand rather than watching the globe being destroyed. Among them, Greta Thunberg, a 16-year old Swedish climate activist, began to skip her school in 2018 just to pressurized the authority to act against climate change. She is not the only one, many young climate activists around the world are working with their communities to prevent the worst ravages of climate change. Not only that they have been successful to gain attention to built movements. As a result on March 15, 2019, an estimated 1.4 million young people in at least 123 countries participated in climate change protests and school strikes. It is a big hope that these young superheroes stood up. Also, there are some simple ways we can follow to cut net human carbon dioxide emissions. The biggest carbon releasing factor related to our daily life is the car. We can sometimes alternate to driving if possible to walk or ride a bicycle to avoid carbon emissions completely. Carpooling and public transportation drastically reduce CO2 emissions by spreading them out over many riders. Drive a low carbon vehicle. We need to know that high mileage does not always mean low CO2 emissions.
