Greenhouse gas emissions should be high within 4 years, says UN report

Global greenhouse gas emissions should increase over the next four years, coal and gas-fired power plants must be shut down in the next decade, and lifestyle and behavioral changes are needed to avoid climate change. Power over climate science.

In every country, the rich have more responsibility for global warming than the poor, SUVs and meat consumption have been singled out, and the carbon footprint for future economic growth is in doubt.

The first part of the East Africa Climate Change Panel was published on Monday, warning of unprecedented changes in the climate, some of which are irreversible. The document, called the Sixth Assessment Report, is divided into three sections: Climate Change Physical Science; Influences and ways to reduce human impact on the climate.

Part Three is not scheduled to be released before March, but some scientists have decided to publish the draft through the Spanish Scientific Rebellion Branch, the Extremist Movement. It was first published by journalist Juan Bordera in the Spanish online magazine CTXT.

Bordera told the Guardian that some people involved in drafting a final document before the liquidation was published in 2022 were concerned.

The richest 10% in the world, the 10% the richest, contribute 36 to 45% emissions, which is 10 times more than the 10% of the poor who account for only three to 5%. . “Consumer spending patterns are associated with large carbon footprints. High emissions control emissions in key sectors, for example, a maximum of 1% of aviation and 50% of emissions, ”it concludes.

The report highlights important life changes, especially between rich countries and the world’s rich. Overheating or overheating of homes, walking and cycling, reducing air travel, and avoiding the use of small amounts of energy-efficient equipment all contribute to a reduction in emissions, the report said.

In many parts of the world, food needs to be changed. In high-calorie and animal-based diets, high-protein diets can lead to a significant reduction in emissions, as well as health benefits: “Ecological diets are 50% higher than the average Western diets,” the report said. .

Giving modern energy to those who lack it now will have an “indifferent” effect on emissions, says the report.

Reducing emissions over the next decade will be crucial for any hope of maintaining global warming at 1.5C of any pre-industrial level, and further damage from the effects of climate change. It is inconsistent with the information and projects in the reviewed literature, so the next immediate step is to limit the temperature at those levels. The report warns.

The report reaffirms the need to stay within 1.5 seconds and reach a net zero emissions by 2050 over the next decade.

The investment needed to transform the world economy into a low-carbon base has also been lost. Current investment is “5 times lower” than required, even at temperatures up to 2C, according to the report. A.D. In 2018, it went to $ 546 billion to cut greenhouse gases and build resilience to the effects of climate change.

“Existing and planned infrastructure and investments, institutional intolerance, and current social bias pose a risk of costly or difficult to mitigate future emissions,” the scientists said.

The working life of coal and gas power plants is often measured in decades, with construction problems having to be eliminated within nine to 12 years of construction. Scientists echo the advice of the International Energy Agency that new fossil fuels cannot be developed if the world is to remain at a temperature of 1.5 ° C.

“The combined economic impact of depleted fossil fuels and capital could reach trillions of dollars,” the report said. This risk can be mitigated by converting investment into low-carbon goods and services.

Technology has not yet been able to play a major role in capturing and storing carbon dioxide.

There are some reasons for optimism, says the report. Solar and wind energy and battery technology are now much cheaper because of policies that encourage their use. Reducing methane emissions also contributes to cooling.

More conservation of forests and land, such as carbon offsets, will also help prevent global warming, but it should not be overly relied upon.

The Spanish publication CTXT, which published the draft, shows that the world economy should change faster than it has to rely on normal GDP growth, but the report does not. The fundamental changes in the economic system, which led to the current crucial trend of sustainable capital accumulation and multiplication, are not clear.

The IPCC did not provide information about the leak, and the purpose of the drafting process is to give scientists time and peace to extend their review without external comment. Jonathan Lynn, Head of Communications at the IPCC, said: For policy makers, the latest internal draft is currently being reviewed by authors.
