Isn't it extremely hot today? Do you remember those days when it was neither extremely hot nor extremely cold? The reason I'm asking you all this is to address the topic of climate change. For several years, the climate has been a crucial subject that affects each of us and our planet Earth. Climate change is a reality.

According to the official website of the Australian Government's Bureau of Meteorology, as of the end of 2017, the Earth has warmed by approximately more than 1 degree Celsius since 1910, when records began on a global scale. This figure includes the ocean surface. Warming is greatest over land, and even greater in the Arctic and parts of Antarctica. This figure may seem low. We face much greater temperature variations in our daily lives due to weather systems and changing seasons. But when you average over the entire planet and over months or years, the temperature differences become much smaller. So an increase of 2 degrees Celsius since the 19th century is actually very high. The significant warming already occurring explains why much of the land's ice is starting to melt and the oceans are rising at an accelerated rate. The heat accumulated on Earth from human emissions is roughly equal to the heat that would be released by 400,000 Hiroshima atomic bombs exploding on the planet every day. Scientists believe that most, if not all, of the warming since 1950 is due to human emissions of greenhouse gases. If emissions continue to be ignored, they say global warming could eventually exceed 8 degrees Celsius, turning the planet into a hellhole and compromising its ability to support a large human population. .
