Earth is warming at unprecedented levels, the risk of causing catastrophic consequences such as drought, forest fires, floods ... worldwide.02: 00/3: 58 nammong in the past few decades, The earthquakes, tsunamis, droughts and tornadoes have often descended on the earth
. Those disasters not only steal many lives, but also cause severe losses of material. According to the Intergovernmental Committee on Climate Change (IPCC) of the United Nations, the situation will become increasing Worse if greenhouse gas emissions continue to take place as high as today. IPCC emphasizes, the future of the earth depends on the current selection of mankind
"Evidence everywhere. If we don't act, the situation will be getting worse, "Xebin Zhang, the climate house in Toronto, Canada, one of the authors of the report. In the past decades, IPCC warns hazards Nature of global warming phenomena. (Artwork) This is the 6th global climate status report of IPCC since 1990, with more than 200 scientists involved in drafting for many years and was approved by 195 countries in the online meeting Last week.Hua nature and alarming numbers only when global emissions returned to level 0 by 2050, the target that many countries commit, the world can reach the goal set in in half Dinh Paris 2015, it is a global temperature increase limit at 1.5 degrees Celsius, compared to the period of industrial money. "The climate that people will experienced in the future, depending on the decision immediately Now ", Valérie Masson-Delmotte, French-based climate, co-chair of the physical science group involved in drafting the report, saying. Earth's surface temperature increased by about 1.1 degrees Celsius compared to the period The segment of the 1850-1900, the highest level since 125,000 years ago, before the nearest ice age, according to IPCC. The oceans are warming up with unprecedented speed since the last closest time, ago first 1,000 years
(Artwork) Water level in global oceans has increased by about 20 cm since 1900. The icebergs crumbled and melted in Antarctica and Greenland island due to global warming has caused the sea level to increase with The rate is 3 times compared to the previous decade. The covers of the tape in the Arctic at the end of the summer is now lower than the previous level of at least 1,000 years ago. The disappearance of glaciers is unprecedented in 2,000 years. The oceans are warming at unprecedented speed since the last end of the closest ice, 11,000 years ago. Scientists said, the level Ch4 in the current atmosphere is the highest in 800,000 years. (Artwork) IPCC report refers to methane gas (CH4), the second most important greenhouse gas emissions after CO2. Scientists said that the current level of atmosphere CH4 is the highest in 800,000 years. IPCC refers to extreme climate change consequences such as hot and dryness and flood rain all over the record level. According to Zhang, if the temperature increases 2 degrees C in this century, extreme climate phenomena Which capital only occurs every 50 years, now will happen every 3-4 years. "We not only face a threat of climate change, but a series of threats that occur simultaneously ", Zhang said. The catastrophic natural dangers like drought, forest fires, floods across the world are happening more and more. (Artwork) According to the content in the report, rising sea level is something that people will feel clearly for centuries, even the whole millennium. If holding the temperature increase at 1.5 degrees Celsius, the sea level increased by 2-3 meters in the next 2,000 years and increased to 6 meters if the temperature increased by 2 degrees C. As a result the life of hundreds of millions of people In the coastal regions will be turned upside down. Report warning that, cannot eliminate some of the most serious impact of climate change, including giant icebags disappearing, arid forests and progress The sudden change of the flow in the ocean.IPCC emphasizes, the most uncertainty in all climate change forecasts is that no one will act. In the past 3 decades, IPCC has warned the hazard of global warming, but countries still have no specific actions to target clean fuels, stop greenhouse emissions. (T / H ) . Dịch vụ:
