The most recent report from the United Nations Intergovernmental Panel on Climate Change (IPCC) was released earlier this week and the results are, in generous words, horrific. The report, compiled by 234 scientists, documents climate changes in every region on Earth and states that some effects are irreversible over hundreds, perhaps even thousands of years. In a press release, UN Secretary-General Antonio Guterres said the report was a “red symbol for humanity”. Here in the United States, we are already seeing severe impacts of climate change West Coast NS the East. If you are looking for good news on climate change, you will have to look for it.
“It’s only guaranteed that things will get worse,” he said. Linda MearnsA senior scientist at the US National Center for Atmospheric Research and co-author of the report told The Associated Press. “No place to run, no place to hide.”
Why the Intergovernmental Panel on Climate Change
The Intergovernmental Panel on Climate Change was created to provide governments with the scientific information they need to develop climate policies. It currently has 195 member states. When the first IPCC report was released in 1990, one of its conclusions was that human-caused climate change would soon become apparent. However, they were unable to confirm that this actually happened. Now, five subsequent evaluation reports, guide in. Scientists can now see how much climate has changed since pre-industrial times, and they are sure that humans are the main cause of it.
The main points of the report
The 3,000-page report isn’t exactly a beach read (the FAQ alone is 96 pages long), but it does include some key points.
The report notes that carbon dioxide is the primary driver of climate change. To a lesser extent, greenhouse gases such as methane and air pollutants are also to blame.
We will see an even more intense rain cycle, as a result of climate change, according to the Intergovernmental Panel on Climate Change. Depending on where you live, it can cause more intense rain and more severe floods or droughts. In addition, precipitation will increase at higher latitudes while decreasing over the subtropics.
Coastal areas will see sea level rise during this century, which will mean more flooding and coastal erosion. “Extreme sea level” events with devastating effects on coastal areas used to occur every 100 years. The IPCC report says these events could soon become annual events.
Higher temperatures will cause more permafrost to thaw, releasing more methane. In addition, this will lead to reduced snow cover, melting of glaciers and ice sheets, and loss of summer sea ice in the Arctic.
Other changes are expected to continue over the next 100 years and are associated with human influence, including marine heat waves, ocean acidification, ocean warming, and declining marine oxygen levels.
In cities, the effects of climate change may include hotter days and flooding due to increased rainfall. Meanwhile, coastal cities will deal with constantly rising sea levels.
“It has been clear for decades that the Earth’s climate is changing, and the role of human influence on the climate system is indisputable,” he said. Valerie Mason Delmot, a French climatologist, research director at the French Commission for Alternative Energies and Atomic Energy, and co-chair of the Intergovernmental Panel on Climate Change. Mason-Delmott also called the report a “reality check”.
Is there a hope?
No matter how poor the report, it is not without hope. The report’s authors believe that human actions can still have a positive impact on climate change in the future. Of course, it will take an incredible amount of effort, and it will not be easy. the Paris Agreement on climate in 2015, aiming to keep the global average temperature below 1.5°C (2.7°F), and six years later, the temperature has already risen 1.1°C (2°F). We are expected to cross the 1.5°C mark in the 2030s. With a 2.0°C (3.6°F) increase in average global temperatures, extreme temperatures will threaten agriculture and health.
Climate stabilization will require strong, rapid and sustainable reductions in greenhouse gas emissions, and access to net zero carbon dioxide emissions. Reducing greenhouse gases and other air pollutants, especially methane, can have health and climate benefits.” panmao chai, a Chinese climatologist, secretary-general of the China Meteorological Society, and co-chair of the Intergovernmental Panel on Climate Change.
If you are interested in how climate change is affecting where you live, I created the Intergovernmental Panel on Climate Change interactive atlas Shows the potential effects of climate change on temperature, precipitation, and more. Unfortunately, just like the conclusions of the IPCC report, those futures shown on the map aren’t currently that bright.
