The new IPCC report is “a red code for humanity,” said UN Secretary-General Antonio Guterres.
Established in 1988 by the United Nations Environment Program (UNEP) and the World Meteorological Organization (WMO), Climate Change (IPCC) evaluates climate change science. The new report is a warning sign to policymakers around the world.
In this photo taken on October 26, 2014, 16-year-old Pia Karawawa was flooded in Kiribati, Aberao village. Kiribati is one of the countries most affected by rising sea levels, as high tides cover many villages and make them uninhabitable.
This was the first time a report approval meeting was held online. There were 234 authors working together to write this 186-hour report.
This report provides an interactive Atlas for the first time to see where people already live and what will happen in the future.
“This report shows that recent climate change is broad, fast, strong and unprecedented in thousands of years,” said Co-Barrett, vice-president of the IPCC.
UNEP Director-General Inger Anderson said scientists have published these messages for more than 30 years, but the world has not heard them.
Highlights from the report –
Mankind must be condemned
Human activity is the cause of climate change, which is a fact. Before the Industrial Revolution, all heat was generated by fossil fuels such as coal, oil, wood, and natural gas.
Since the 19th century, global temperatures have risen by 1.1 degrees Fahrenheit[1.1 ° C]. They last more than 100,000 years, and the increase is only due to natural forces.
Who is Michael Freedom The effects of climate change are being felt in all corners of the globe. In particular, “IPCC is very straightforward from previous assessments as it is linked to climate change and severe weather events.
S. Permission Hide the 1.5C mark excessively
According to the report, the brightest and most carefree situation is that if we do everything right and start reducing emissions now, it will exceed 1.5C by 2030. However, the temperature drops to 1.4 C.
Control emissions and do the rest of the earth
According to the report, efforts to reduce emissions could reduce global warming by more than 1.5 degrees Celsius.
The changes we are living in are unprecedented. However, it can be reversed to some extent. And nature takes a long time to heal. This can be achieved by reducing greenhouse gas emissions. Some of the benefits may be immediately apparent, but “it could take 20 to 30 years for global warming to subside,” says IPC.

Increase in sea level
Since 1900, the world’s oceans have risen by about 20 inches (8 inches), almost tripled over the past decade. At the top of Antarctica (especially Greenland), ice melting and melting ice has been replaced as the main driving force.
If global warming is limited to 2 degrees Celsius, the oceans will rise by 0.5 meters in the 21st century. It will continue to rise by 2,200-fold to 2 meters above the IPC forecast in 2019.
Due to the instability of the ice sheet, scientists will not be able to prevent a total increase of 2 meters by 2,100 in extreme conditions.
CO2 is always high
A.D. By 2019, CO2 levels were more than “at least 2 million years old.” Methane and nitrous oxide levels, the second and third major contributors to global warming, rose by “at least 800,000 years” in 2019. I reported Freedom..
Control methane
The report contains the most important information on greenhouse gas emissions (CH4) after CO2, and the goal of the Paris Agreement is to control emissions. It warns of violations.
Anthropogenic sources can be widely distributed in natural gas production, coal mining and sewage disposal, and animal and fertilizer management.
CH4 emits only a small amount of CO2 in the atmosphere, but is more efficient at catching heat. CH4 levels are at least 800,000 years old.
Natural partners are weakening
Since the 1960s, forests, soils, and oceans have accounted for 56% of human emissions, but their emissions have been halved. Without the help of nature, the earth would not have been so hot and humid.
However, these collaborators are showing signs of replenishment by fighting global warming (known as carbon washers in this role), and as the century progresses, the amount of anthropogenic carbon they receive may decrease.
Smoking
The report suggests that “negative emissions” could re-emerge. You can cool the earth by absorbing or separating carbon from the atmosphere. This is a possible suggestion, and there are small experiments that have been tried, but the technology is not yet perfect. He said the panel could work from the middle of this century, but did not explain how it should be done, and many scientists were skeptical about its effectiveness.
The city carries the heaviest load
Expert It warns that many effects of climate change, such as coastal heat, flooding and rising sea levels, could worsen in cities. In addition, IPCC experts warn that conditions such as low snowfall, snowfall and rapid changes in ocean currents cannot be avoided.
