Methane Big Part Of ‘Alarming’ Rise In Planet-Warming Gases

Published

The National Oceanic and Atmospheric Administration announced that a rise methane in the atmosphere increased at its fourth-highest annual rate in 2022, part of an overall rise in planet-warming greenhouse gases that the agency labeled “alarming.”

Though carbon dioxide receives greater attention for its involvement in climate change, scientists are especially concerned about methane because it traps far more heat — approximately 87 times more than carbon dioxide on a 20-year timeline.

Methane, a gas that comes from garbage dumps, oil and natural gas pipelines, and animals, has risen a lot since 2020. Scientists say it shows no signs of stopping, despite urgent pleas from scientists and policymakers that time is running out to reach the Paris Agreement’s temperature limits and avert the most damaging effects of climate change.

“NOAA scientists’ observations in 2022 show that greenhouse gas emissions continue to rise at an alarming rate and will stay in the atmosphere for thousands of years,” said NOAA Administrator Rick Spinrad in a statement that came with the report. “The time has come to address greenhouse gas pollution and reduce human-caused emissions as we work toward becoming a climate-ready nation.”

In 2022, methane increased by 14 parts per billion to 1,911.9 ppb. It increased significantly quicker in 2020 (15.20 ppb) and 2021. (17.75 ppb).

Methane gas escapes rise through wells and natural gas lines, as well as from manure ponds, decaying landfills, and cattle.

“Ruminant animal herds, particularly goats, sheep, and cows, are one of the largest human-driven sources of methane,” said Stephen Porter, a Brown University professor of ecology and assistant provost for sustainability.

Scientists continue to discover that methane emissions from the fossil fuels industry and the environment are vastly understated.

The precise amounts of methane emitted by human activities vs. natural habitats in recent years are unknown, but scientists say humans have limited control over ecosystems that begin leaking more methane due to warming.

“If this rapid rise is due to wetlands and natural systems responding to climate change, that’s very scary because we can’t do much to stop it,” said Duke University professor and former NASA climate scientist Drew Shindell. “If methane leaks from the fossil fuels sector, we can enact regulations.” But we can’t create rules on what swamps do.”

Scientists are also investigating how the persistent three-year La Nina pattern may have influenced methane emissions caused by increased rainfall in tropical wetlands.

According to Shindell, human-induced methane emissions account for around 26% of the warming produced by human activity.

Transitioning away from fossil fuels and limiting the number of ruminant animals fed are “sure-fire ways to reduce methane in the atmosphere and limit warming,” according to Porter.

According to the International Energy Agency, existing technologies may eliminate 70% of methane emissions by 2022.

According to the NOAA report, carbon dioxide and nitrous oxide levels will rise significantly in 2022.

Carbon dioxide levels increased to 417.06 ppm in 2022, making them 50% higher than pre-industrial levels. Nitrous oxide, the third-most major greenhouse gas emitted by humans, increased to 335.7 ppb, owing mostly to fertilizers and manure from the increasing agricultural sector.

Britain Must Be Ready for War in 3 Years, Warns New Army Chief

Britain Must Be Ready for War in 3 Years, Warns New Army Chief

The new head of the Army has stated that Britain must be prepared to fight a war within three years.

Gen Sir Roland Walker has issued a warning about a variety of risks in what he calls a “increasingly volatile” environment.

However, he stated that war was not inevitable and that the Army had “just enough time” to prepare to prevent conflict.

He stated that the Army’s fighting capacity would be doubled by 2027 and tripled by the end of the decade.

Gen Walker warned that the Britain was under threat from a “axis of upheaval” in his first speech as Prime Minister on Tuesday.

Among the primary concerns confronting the Britain in the next years, as noted by the general in a briefing, is an enraged Russia, which may seek vengeance on the West for helping Ukraine, regardless of who wins the war.

He stated: “It doesn’t matter how it finishes. I believe Russia will emerge from it weaker objectively – or completely – but still very, very dangerous and seeking some form of retaliation for what we have done to assist Ukraine.”

Britain’s Government Defence Review and Military Challenges

He also warned that China was determined to retake Taiwan, and Iran was likely to seek nuclear weapons.

He stated that the threats they posed may become particularly acute in the next three years, and that these countries had formed a “mutual transactional relationship” since the war in Ukraine, sharing weaponry and technology.

However, he stated that the path to conflict was not “inexorable” if the UK re-established credible land troops to assist its deterrent strategy for avoiding war.

In his speech, he described his force of slightly over 70,000 regular troops as a “medium-sized army” and made no direct call for additional resources or men.

However, he pushed the British Army to adapt swiftly, focussing on technology such as artificial intelligence and weaponry rather than numbers.

His ultimate goal is for the Army to be capable of destroying an opponent three times its size.

This would entail firing quicker and farther, he said, aided by lessons learnt from the Ukraine war.

The general’s speech at the Royal United Services Institute land warfare conference comes only one week after the government began a “root and branch” defence review to “take a fresh look” at the challenges facing the armed services.

Defence Secretary John Healey launched the assessment, describing the existing status of the armed forces as “hollowed-out” and stating that “procurement waste and neglected morale cannot continue”.

According to the most recent Ministry of Defence (MoD) numbers from April 2024, the Britain’s regular Army forces total 75,325 troops (excluding Gurkhas and volunteers).

That figure has been declining in recent years, as recruiting has failed to match retention. The previous Conservative administration lowered the planned headcount from 82,000 to 72,500 by 2025.

Members of the NATO military alliance have agreed to spend at least 2% of GDP on defence by 2024, but several countries are unlikely to fulfil this goal.

The Britain presently spends 2.3% of its GDP on defence. Prime Minister Sir Keir Starmer has previously stated that the defence review will include a “roadmap” for increasing this to 2.5%, however he has yet to provide a date for this promise.

PARIS — Katie Ledecky is looking for clean Olympic races. On Wednesday, Hope had pretty much reached her limit.

The American swimmer hopes to add to her six gold medals as she competes in the 400, 800, and 1,500 meters at the Paris Games. Her program starts with the heavy 400 on Saturday, featuring Ariarne Titmus and Summer McIntosh.

Katie Ledecky Hopes For Clean Races At Paris Olympics In The Aftermath Of The Chinese Doping Scandal

The 27-year-old Katie is competing in her fourth Summer Olympics, but the first since a doping scandal involving almost two dozen Chinese swimmers who tested positive for a banned chemical before the Tokyo Games — yet were permitted to compete with no consequences. The controversy has raised serious worries regarding the effectiveness of anti-doping initiatives.

“I hope everyone here is going to be competing clean this week,” Ledecky claimed. “But what truly counts is, were they training cleanly? Hopefully this has been the case. Hopefully, there has been worldwide testing.”

The International Olympic Committee has expressed concern over the ongoing US investigation into possible doping by Chinese swimmers. While awarding the 2034 Winter Olympics to Salt Lake City on Wednesday, the IOC urged Utah officials to do whatever they could to stop the FBI investigation.

“I think everyone’s heard what the athletes think,” Katie added. “They seek transparency. They want more answers to the remaining questions. At this point, we are here to race. We are going to race whoever is in the lane next to us.

“We are not paid to conduct the tests, so we trust those who follow their regulations. That applies both today and in the future.

London Heatwave Alert High Temperatures Set to Soar to 29C Next Week

As the summer holidays begin, London may experience an official heatwave with temperatures reaching up to 29 degrees Celsius.

The Met Office predicts a long period of sunny and dry weather for London after a soggy spring and summer.

After a cloudy day on Saturday, temperatures are expected to reach 27C on Sunday, with lots of sunlight.

On Monday and Tuesday, temperatures are forecast to peak at 29 degrees Celsius. Monday is forecast to offer more sunlight, while Tuesday may see some gloomy weather.

Temperatures are expected to remain in the high 20s next week, with lows of approximately 18C.

According to the Met Office, a heatwave is “an extended period of hot weather relative to the expected conditions of the area at that time of year, which may be accompanied by high humidity.”

In the United Kingdom, a heatwave is proclaimed when daily temperatures meet or surpass a certain level for at least three consecutive days.

In London, the heatwave threshold is 28 degrees Celsius.

The Met Office reported that the UK is experiencing hotter and wetter weather on average due to climate change.

The UK experienced its warmest May and April on record this year, despite damp and dismal conditions in many areas.

According to the Met Office’s State Of The UK Climate 2023 report published on Thursday, the UK experienced historic levels of extreme weather last year.

In the United Kingdom, 2023 was the second warmest year on record, bringing storms, flooding, strong heatwaves, and rising sea levels; only 2022 was warmer.

It was 0.8°C higher than the average from 1991 to 2020, and 1.66°C higher than the 1961 to 1990 average.

However, 2023 will be a “cool year” in comparison to 2100, based on the planet’s warming trajectory.

The government’s plan to adapt to the hazards presented by climate change is currently being challenged in the High Court by campaigners who allege the Tory administration’s July 2023 National Adaptation Programme (NAP) fails to adequately address 61 concerns.
