Impact of Human Activity on Climate Change
by Abdou Sani Boukari ConsultantLeonardo DiCaprio won the Oscar at 2016 ceremony for Best Actor in a Leading Role for his performance in the movie "The Revenant" (2015).
In his acceptance speech, the actor highlighted the importance of climate change, he said: "Climate change is real, it is happening right now. It is the most urgent threat facing our entire species, and we need to work collectively together and stop procrastinating..... Let us not take this planet for granted."Indeed, Humans are changing the climate 170 times faster than natural forces, according to a new study published in the peer-reviewed journal The Anthropocene Review.
For 4 billion-plus years, astronomical and geophysical factors, such as solar heat output and volcanic eruptions, were the dominating influences on Earth’s climate ; but over the past six decades, human activities like the burning of fossil fuels and deforestation “have driven exceptionally rapid rates of change,”
Natural forces still have an effect in modern times, “but currently on orders of magnitude less” than human activity. If we take a baseline of the last 7000 years, until recently, global temperature decreased at a rate of 0.01 °C per century. The current rate (last 45 years) is a rise of 1.7 °C per century – 170 times the baseline and in the opposite direction.Sponsor Ads

Consultant@Anita, you are right. Indeed, by the start of the 21st century, it was clear that climate change would bring serious harm to many regions — some more than others. Many kinds of damage were already beginning to appear. Myles R. Allen, a climate scientist at Oxford University in Britain, quoted by Justin Gillis, "Wild Weather, Across the Map," New York Times, Dec. 31, 2015" https://www.nytimes.com/2015/12/31/science/climate-chaos-across-the-map.html?_r=0 noted this fact : ""As scientists, it's a little humbling that we've kind of been saying this for 20 years now, and it's not until people notice daffodils coming out in December that they start to say, 'Maybe they’re right.' http://history.aip.org/climate/impacts.htm Feb 21st 2017 16:55 Edited in Feb 21st 2017 17:14 |

The planet is being exhausted by humans indeed. The climate change all over the world is the terrible consequence.
