It is clear that the net zero push has so far been a complete failure. But the green focus on renewables has made this inevitable.

WMO records largest increase in methane concentrations since measurements began
Geneva/New York, October 26 (WMO) – In another worrisome climate change warning, atmospheric levels of three major greenhouse gases – carbon dioxide, methane and nitrous oxide all hit record highs new record by 2021, according to a new report from the World Meteorological Organization (WMO).
WMO greenhouse gas bulletin reported the largest annual increase in methane concentrations in 2021 since systematic measurements began nearly 40 years ago. The reason for this particular increase is unclear, but appears to be the result of both biological and human-induced processes.
The increase in carbon dioxide levels from 2020 to 2021 is greater than the average annual growth rate over the past decade. Measurements from WMO’s Global Atmosphere monitoring network stations show that these levels will continue to rise into 2022 globally.
Between 1990 and 2021, the warming effect on our climate (called radiative forcing) by long-lived greenhouse gases has increased by nearly 50%, of which carbon dioxide makes up about 80% this increase.
Concentrations for carbon dioxide in 2021 are 415.7 parts per million (ppm), methane at 1908 parts per billion (ppb) and nitrous oxide at 334.5 ppb. These values constitute 149%, 262% and 124% of pre-industrial levels, respectively, before human activities began to disrupt the natural equilibrium of these gases in the atmosphere.
“The WMO GHG Bulletin once again highlights the enormous challenge – and vital necessity – of urgent action to cut greenhouse gas emissions and prevent further global temperature rise in the future. future,” said WMO Secretary General, Prof. Petteri Taalas.
“Continued increases in concentrations of key heat-trapping gases, including a record acceleration in methane concentrations, suggest that we are headed in the wrong direction,” he said.
“There are cost-effective strategies to tackle methane emissions, particularly from the fossil fuel sector, and we should implement these strategies immediately. However, methane has a relatively short lifetime, less than 10 years, and therefore its impact on climate is reversible. As a top and most urgent priority, we must cut carbon dioxide emissions, which are a major cause of climate change and related extreme weather, and will affect the climate for thousands of years. polar ice loss, ocean warming and sea level rise,” said Professor Taalas.
“We need to transform industrial systems, energy, transport and entire ways of life. The necessary changes are economically and technically affordable. Professor Taalas said.
WMO UN Climate Change Conference, COP27, in Egypt from 7-18 November. On the eve of the conference in Sharm-el-Sheikh, it will present the Interim Status of Global Climate 2022 report, which will show how greenhouse gases continue to drive climate change and weather how harsh. The years 2015 to 2021 were the seven warmest years on record.
WMO reports seek to stimulate COP27 negotiators into decision-makers who act more ambitiously to achieve The goal of the Paris Agreement to limit global warming to below 2, preferably 1.5 degrees Celsius, above pre-industrial levels. The average global temperature is currently 1.1°C above the pre-industrial average of 1850–1900.
With the need to strengthen the greenhouse gas information base for decisions about climate mitigation efforts, WMO is working with the broader greenhouse gas community to develop a framework for internationally coordinated and sustainable global greenhouse gas monitoring, which includes observing the design of international networks and exchanges and using the observed results. It will engage with the broader international and scientific community, particularly in relation to the observation and modeling of land and ocean surfaces.
WMO measures the concentration of greenhouse gases in the atmosphere – what is left in the atmosphere after the gases are absorbed by sinks such as the oceans and biosphere. This is not the same as emissions.
The United Nations Environment’s separate and complementary Emissions Gap Report will be released on October 27. The Emissions Gap Report evaluates the latest scientific research on current greenhouse gas emissions. present and estimated in the future. This difference between “where we can go and where we need to go” is called the emissions gap.
As long as emissions continue, global temperatures will continue to rise. Due to the long life of CO2observed temperature levels will persist for decades even as emissions rapidly drop to zero.
Highlights of Newsletter
Carbon dioxide (CO2)
Atmospheric carbon dioxide will reach 149% of pre-industrial levels by 2021, mainly due to emissions from fossil fuel combustion and cement production. Global emissions have increased again since the COVID-related shutdown in 2020. Of the total emissions from human activities during 2011–2020, about 48% accumulated in the atmosphere. , 26% in the ocean and 29% on land.
There is concern that the ability of land and ocean ecosystems to act as “sink pools” could become less efficient in the future, thereby reducing their ability to absorb carbon dioxide and function. acts as a buffer against a larger increase in temperature. In some parts of the world, the process of converting land to CO2 source occurred.
Methane (ONLY)4)
Atmospheric methane is the second largest contributor to climate change and includes a diverse mix of overlapping sources and sinks, making it difficult to quantify emissions by source type. .
Since 2007, the average global concentration of atmospheric methane has increased at an increasingly rapid rate. The year-over-year increases in 2020 and 2021 (15 and 18 ppb respectively) are the largest since the systematic record began in 1983.
The cause is still being investigated by the global greenhouse gas science community. The analysis indicates that the largest contribution to the new increase in methane since 2007 has come from biological sources, such as wetlands or rice paddies. It is not yet possible to say whether the extreme increases in 2020 or 2021 will represent a climate response – if it warms, organic material decomposes faster. If it decomposes in water (without oxygen), this results in methane emissions. Therefore, if tropical wetlands become wetter and warmer, more emissions are expected.
The significant increase can also be attributed to natural year-to-year variability. The years 2020 and 2021 see La Niña events that are associated with increased rainfall in tropical regions.
Nitrogen oxide (N .)2O)
Nitrogen oxide is the third most important greenhouse gas. It is released into the atmosphere from both natural (approximately 57%) and anthropogenic (approximately 43%), including oceans, soil, biomass burning, fertilizer use, and various industrial processes. . The increase from 2020 to 2021 is slightly higher than the increase from 2019 to 2020 and higher than the average annual increase over the past 10 years

Obviously I think the WMO CO2 alarm theory is a joke. But the bigger joke is that greens have had a proven method of reducing CO2 emissions within their reach since the mid-20th century, but they chose not to use it.
If the world focused on affordable nuclear power, if the world switched most of its electricity production to carbon-free nuclear, like France did in the 1970s, greens would probably generate at least one small dents in those charts.
The Greens insist nuclear is too expensive, but that’s simply not true – otherwise how could France do it? Either you accept the idea that the French are the top technical geniuses in the world, or you accept that what makes nuclear power so expensive in most countries is something other than construction and operation costs of nuclear plants.
