Scientists say it’s now or never to stop global warming

The final part of the 6th Assessment Report, which is divided into three working groups of the Intergovernmental Panel on Climate Change (IPCC) within the United Nations (UN), has been published.

The report, titled Climate Change Mitigation, which focuses on how governments and citizens can avoid the worst effects of the climate crisis, was ratified by 195 member states on April 4.

The report’s findings suggest that global greenhouse gas emissions need to peak over the next three years and then decline rapidly to avoid the worst effects of the climate crisis.

Even if we reach such a point, the report says, we will need technology capable of extracting carbon from the atmosphere by 2050.

CARBON EMISSIONS MUST REACH BY 2025 AT THE LATEST

The report, carefully reviewed by scientists and government officials, and which will guide the world to avoid a very dangerous future, points out that global carbon emissions are expected to decline by 43% by 2030.

Speaking at the press conference held on the occasion of the release of the IPCC report, United Nations Secretary-General Antonio Guterres said: “There is a big difference between what some governments and big companies say and what they do. To put it bluntly, they lie. and the consequences will be disastrous.”

The researchers say that increasing air temperature to these levels will cause “unprecedented heat waves, terrible storms and widespread water shortages” around the world, and we should limit the increase in temperature. temperature at 1.5 degrees to avoid such extreme weather events and disasters.

The IPCC report indicates that this is only possible if we completely change our global energy production, our industries, our modes of transport, our consumption habits and our relationship with nature.

According to the report, for us to be limited to this threshold, carbon emissions from everything we produce and consume to sustain our lives must peak by 2025 at the latest and decline as quickly as possible. According to experts, it is very important for the whole world to reach net zero by 2050.

In other words, we must never produce more than the carbon dioxide emissions we have caused over the past 10 years in order to be limited to 1.5 degrees Celsius.

“The report shows that we are now at a critical point to limit global warming to 1.5 degrees Celsius,” said Heleen De Coninck, lead author of the IPCC report and professor of socio-technical innovation and climate change at Eindhoven Technical University.

“Our greenhouse gas emissions must decline rapidly and peak by 2025 at the latest. Just after 2050, we will need to capture carbon dioxide from the atmosphere.”

RENEWABLE ENERGY

Researchers say the next few years are critical, and unless carbon emissions are reduced by 2030, warming cannot be stopped from reaching dangerous levels.

In the short term, our energy production methods will be very important in this process.

Fortunately, the prices of solar panels and wind turbines around the world have fallen by almost 85% in the last 10 years.

Kaisa Kosonen, of the environmental organization Greenpeace, said: “The fossil fuel industry, which continues both wars and the climate crisis around the world, has come to an end. New investments in fossil fuels must no longer be made, and existing coal and natural gas power plants must be shut down quickly.”

On the other hand, the IPCC report suggests that people’s lifestyle and food consumption habits are also expected to change.

IPCC Co-Chair Priyadarshi Shukla said: “With the right strategy, infrastructure and technology to help us change our habits and behaviors, we can achieve a 40-70% reduction in greenhouse gas emissions. greenhouse by 2050. These changes in our lifestyles have also proven to be healthier for us.”

For this, governments must encourage people to walk, eat healthy, consume less meat and provide the necessary infrastructure for electric vehicles.

However, the report says that planting trees alone will not be enough to keep global warming below the 1.5 degree threshold, and that carbon dioxide must be directly captured and removed from the atmosphere through new technologies.

However, these technologies are too expensive at the moment, and some IPCC members doubt that such an approach will work.

“This report is full of illusions. The idea of ​​removing carbon from the atmosphere so quickly and in large quantities is particularly worrying,” says Arthur Petersen, professor at UCL University.

“There is a lot of false imagination in this report.”
