Is Climate Change Already Irreversible – Earth scientists released their strongest assessment of climate change on Monday, saying the world will warm, the effects of climate change will increase — and humans are to blame.
The report issued by the Intergovernmental Panel on Climate Change (IPCC) said that unless there is an “immediate, rapid and significant” reduction in greenhouse gas emissions, it will limit global warming. world to the acceptable threshold between 1.5 degrees Celsius “is not possible. .”

Is Climate Change Already Irreversible
Even in the best-case scenario, scientists say global warming is “likely” to break that threshold in the next two years, faster than some estimates. first.
Big Findings From The 2023 Ipcc Report On Climate Change
“Climate change is a problem now. Nothing is safe, and the storm is getting worse,” said Inger Andersen, director of the United Nations Environment Program at a press conference opening the report. “We must take care of climate change. it is an immediate threat.”
If the global temperature rises by more than 2 degrees Celsius, the report says that the temperature will hit the critical thresholds for agriculture and human health.
“The alarm bells are ringing, and they can’t be ignored: Greenhouse gas emissions from burning fossil fuels and deforestation are harming our planet and leaving billions of people are in immediate danger,” he said in a statement.
Greta Thunberg, the activist in the IPCC, said, “there is nothing really surprising” and a “cautionary” summary of the available information.

“It does not tell us what to do. It is up to us to be brave and make decisions based on scientific evidence,” he complained, adding that the cloud can prevent the best solution, but if he begins to “treat the problem as a problem.”
The report provides the most comprehensive assessment of how greenhouse gas emissions have changed over decades of burning fossil fuels, oil and gas for energy.
According to the report, the concentration of carbon dioxide gas is keeping the temperature at its highest level for at least 2 million years, enough to ensure climate disruption for hundreds if not more. thousands of years to come.
The danger is even longer for the world’s oceans, ice sheets and sea levels, which will be “irreversible for hundreds to thousands of years” despite the heat trapped in the depths of the ocean to melt.

Sea levels are rising at the fastest rate in 3,000 years, while Arctic sea ice is at its lowest level in 1,000 years.

“It is indisputable that human activities have caused and are causing climate change,” said Panmao Zhai, climatologist and chairman of IPCC Working Group I.
“What’s new in this report is that we have a better understanding of the connections between the emissions we emit and global warming and climate change. and the weather.”

The IPCC report comes as massive fires are raging in Greece, Turkey, Italy and California. And just weeks after a massive flood left hundreds of thousands dead in Germany, Belgium and China. not taken.
The report should be in order to wake up world leaders meeting in Glasgow, Scotland in November for the COP26 climate talks. With critics saying that the pledges made so far are not enough to reduce greenhouse gas emissions, countries are facing an even greater increase in emissions. ambitious – and develop specific plans for how they will reach those goals. .
“If we stop warming to 1.5 degrees, then we will stop many of these pollutants from becoming more severe,” said the IPCC author and scientist of University of Oxford Frederica Otto. “And I think that while we’re stuck with some changes — especially sea level rise, melting glaciers — decades from now, we can slow down those changes. and we can stop a lot of other things from going up and down. CO2 over the next decade.” A public report by the UN’s climate panel is a ‘reality check’ ‘ and an encouraging message, but there is still time to act in the fight against the climate crisis.
Jackson Ryan is the scientific editor of the editor, and winner of many awards. He used to be a scientist, but he found that he wasn’t very happy sitting on a factory floor all day. He found science writing to be the best job in the world – allowing him to tell stories about space, Earth, climate change, and the people who do it. at the limits of human knowledge.

Facts That Prove The World Is In A Climate Emergency
The evidence is unequivocal: humans have warmed the Earth, and every part of the Earth is affected by climate change.
This is the main idea of the report published on Monday by the Intergovernmental Panel on Climate Change. The document, a remarkable work of the international community, presents the scientific basis for the climate crisis and the various changes seen in the Earth’s climate system due to man. power and performance.
It provides the most recent estimates of climate change exceeding 1.5 degrees Celsius of warming in the coming years, and – according to IPCC reports from the 1990s – the he urges immediate action to reduce gas emissions.
The report, Climate Change 2021: The Physical Science Base, was written and reviewed by more than 230 leading experts in IPCC Working Group I. to actions taken to eliminate emissions in the coming years.

“What has been reported is that there is growing evidence that we need to be concerned about climate change, and climate change,” said Mark Howden, is a research scientist at the Australian National University and an author of the report.
At 14,000 words, the report examines the basic science behind global warming, rising sea levels, melting glaciers and ice sheets. , oxygen depletion and increased ocean acidification, and extreme weather events.
The report is a “reality check,” according to Valerie Masson-Delmotte, a French engineering scientist who leads Working Group I. The possibility of exceeding the threshold of 1.5 ° C indicated in the 2015 Paris Agreement is up and time is running out.
While the science may be discouraging, the report offers a small window of opportunity for policymakers to set emission reduction goals and change our current trajectory. , Howden note.
Donald Trump Could Put Climate Change On Course For ‘danger Zone’
You might be thinking “I’ve heard it all before.” Scientists have been beating this box for decades and so has the IPCC. Monday’s report was a major highlight in a long campaign.
“The general message hasn’t changed,” said Lisa Alexander, a research scientist at the University of New South Wales in Sydney and an author of the new report.
The IPCC was established by the United Nations Environment Program and the World Meteorological Organization in 1988 to understand the drivers and impacts of climate change. monitoring research and studies on climate change. Its last major review report was published in 2014, with the Working Group I report published a year earlier.
Since then, eight years of data have been analyzed, allowing the IPCC to determine, with increasing confidence, the extent to which humans have caused global warming. “In those eight years, we’ve seen very large changes in temperature, for example,” Howden said.

The problem forces us to rethink all aspects of human life. Just this week, the Tokyo Olympics reached the finish line without major disruption due to COVID-19 – but a worse threat overshadowed the event: extreme heat.
Athletes suffered from heat and humidity, with archers and tennis players falling off the field. Officials moved the marathon from Tokyo to Sapporo, in northern Japan, in 2019 in an attempt to avoid rising temperatures in the host city – only to find Sapporo hot to begin with the race was an hour earlier. .
The report examines some of the most extreme climate change and events on record, addressing some of the heat waves, droughts and floods that have devastated the world in recent years. and using new data to strengthen their links to human activity and warming.
But increasing temperature is only one aspect of the wild system. In recent years, unprecedented wildfires have erupted along the east coast of Australia and the western United States. We are starting to see more storms and storms with heavy rain events and retreating snow, ice and sleet.
