In KBS1's Docs Insight, which will be broadcast on the 30th, the `` Thousands of Millennium Deaths, Baobab's Warning '' will be broadcast
◆ millennium collapsed
Baobab tree, known for tropical Africa and one of the largest and longest-living plants in the world.
Since living for more than two thousand years, it is very rare for a person to see Baobab trees die in their lifetime.
It is a key species that plays an important role in maintaining the balance of local ecosystems, and it is a baobab tree that provides berries rich in vitamin C to help people live.
But in recent decades, there has been a sudden death of Baobab trees, the haven of African souls.
"Everyone was sad when this baobab tree, a symbol of South Africa, fell down."
◆ Sudden death of baobab, the cause of climate change
Dr. Stephen Woodborne, an analytical scientist of carbon isotopes in South Africa, and Sarah Venter, a baobab ecologist in South Africa.
The producers accompanied the two scholars to a field of fallen baobabs in northern South Africa.
Dr. Stephen Woodborne and a collaborative team published their findings in the 2018 International Plant Journal Nature about the causes of the subsequent collapse and death of the oldest and largest baobabs, and the causes of climate change that influenced South Africa.
Estimated by.
What does baobab tree suddenly fail to adapt to rapid environmental changes?
◆ The age of climate disaster is coming
Recent extreme weather events such as heat waves, cold waves, heavy rains and droughts, forest fires and typhoons caused by climate change have put all humans and ecosystems at risk in the 21st century.
The world's summer in 2019 is the hottest summer ever since weather observations.
Paris in Western Europe, France, reached 46 degrees, and the highest temperature was 34.8 degrees in Sweden, a region in northern Europe, where summer temperatures do not normally exceed 20 degrees.
More than 50 degrees of murderous heat waves hit India.
The world is now entering an era of climate disaster beyond climate change.
◆ Keep it within 1.5 ℃ of global warming
“Even if the global average temperature rises just 2 degrees, the earth will become uncontrollable beyond human life” (John Lockstrom, Director of the Potsdam Institute for Climate Impact Research).
Scientists point out that extreme weather events are happening because of global warming caused by human activity.
The average global temperature, which has risen for 10,000 years from the ice age to the inter-glacial period, has risen by 4 degrees, and in just 100 years of this century, humans have increased the global average by 1 degree.
That's 25 times the speed.
The amount of carbon dioxide emitted by humans is about 40 billion tons per year.
This way, the earth enters into an uncontrollable state beyond which humans can live.
According to the 2018 Special Report on Climate Change (IPCC), the world's premier climate scientists' meeting, if global warming continues at the current rate because carbon emissions are not reduced, it will be 2030.
Between 2052 and 2052, the rate of increase will exceed 1.5 degrees, which means that by 2030, carbon emissions will have to be cut by nearly half by 45%.
Is this possible?
◆ Children on the Street, 'Friday for the Future'
“What we want is climate justice!
When do you want to change? Right now! ”
In the square in front of the Swedish Stock Parliament, there are youth who do a "School Strike for Climate" every Friday.
It criticized governments and adults irresponsible for climate change and urged effective measures.
`` Fridays for Future, '' a global youth climate action group, began in 2018 in a one-person street demonstration by Sweden's 17-year-old girl Greta Tunbury.
Since then, more than 12 million people have participated in class refusal protests that have spread to young people around the world.
In September, when the UN Climate Summit took place in September, youths from all over the world took to the streets, and on September 27, more than 500 youths were absent from Sejong-ro, Seoul, South Korea.
Refuse to listen to a plea for a reason.
Docs Insight's Millennial Death, Baobab's Warning starts with a warning signal from the Baobab tree to examine how much of each country's climate change is discussed and recognized, and a consensus on climate change is formed.
We want to urge change.
