Atmospheric CO2 Levels reach Historic Levels, Mauna Loa Observatory in Hawaii warns about Trouble in the Air
- The headline from a year’s worth of test results on CO2 levels from the Mauna Loa Observatory in Hawaii states that the atmospheric CO2 levels may never fall below 400 ppm
- the more carbon dioxide that is in the atmosphere, the more heat will be trapped and the warmer the planet will become
- The Organization for Economic Cooperation and Development says we have to cap the amount of carbon in the atmosphere at 450 ppm
Oct 01, 2016: The atmospheric CO2 levels may never fall below 400 parts per million (ppm) ever again.
That’s the headline from a year’s worth of test results on CO2 levels from the Mauna Loa Observatory in Hawaii.
In a study released this month, lead author professor Richard Betts of the University of Exeter blames the cyclical Pacific Ocean warming phenomenon known as El Nino in part for the grim record. In his research, published in Nature Climate Change, Betts says El Nino “warms and dries tropical ecosystems, reducing their uptake of carbon, and exacerbating forest fires.”
Betts and his colleagues were able to predict this landmark. “I was looking at the numbers this morning,” NASA scientist Ben Poulter told VOA. “It is remarkable that they were able to make these predictions in 2015.”

Carbon dioxide is odorless and tasteless, and it makes up less than 1 percent of our atmosphere. But this small amount of CO2 has a big impact on the planet. According to the National Oceanic and Atmospheric Administration, without the warming of the planet that carbon dioxide and other so-called greenhouse gases provide, Earth’s average temperature would fall below freezing.
But that’s where the old saying about too much of a good thing comes into play, because the more carbon dioxide that is in the atmosphere, the more heat will be trapped and the warmer the planet will become.
The planet didn’t reach the 400 ppm mark by itself. Prior to the Industrial Revolution, CO2 levels were at 280 ppm. When tests at Mauna Loa began, the level was at 315 ppm. Scientists say human contributions have played a large part in pushing the level over 400 ppm.
All of the carbon people are pumping into the atmosphere is having an impact on the planet. But what exactly is that impact? That’s been the challenge facing climate scientists for decades.
At the very least, according to NOAA, warming can cause “sea level rise, shifting precipitation patterns, expansion of areas affected by drought, increasing numbers of severe heat waves, and more intense precipitation events.”
Already, some places are getting wetter, and some places are getting drier. The good news is that humans are really adaptable. The bad news is that a host of other creatures aren’t.
And it gets worse: A lot of that excess carbon gets absorbed by the world’s oceans, making the water more acidic. NOAA says this interferes with such things as “the ability of marine plants and animals to build their shells,” and that ultimately threatens “a reorganization of the entire marine food chain, which could lead to a mass extinction event.”
NewsGram brings to you top news around the world today.
But will all this happen? That’s the the part that concerns climate scientists the most. Hitting 400 ppm means we’re in uncharted territory. The last time atmospheric CO2 levels were this high is unclear, but a number of competing studies put the date at millions of years ago. We may not know whether an extinction event lies ahead, but we can count on weather events like blizzards and droughts becoming more extreme, and more common.
Poulter says the 400 ppm level “tells us that society moving way too fast toward dangerous CO2 concentration in the atmosphere.” So what can we do to fix it?
The Organization for Economic Cooperation and Development says we have to cap the amount of carbon in the atmosphere at 450 ppm. That keeps us below an average global temperature increase of 2 degrees Celsius, which was the goal set at a 2010 U.N. conference on climate change.
But to do that, the world may need to phase out use of dirty fuel like coal and cut back on oil. And according to the White House, “global emissions would have to decline by about 60 percent by 2050 [and] industrialized countries’ greenhouse gas emissions would have to decline by about 80 percent by 2050.”
Check out NewsGram for latest international news updates.
Poulter says, “We’re only about 15 to 20 years away from reaching the 450 ppm target,” which means efforts to cut carbon emissions have to start now. Forty-one nations — including the world’s biggest polluters, the United States, China and those in the European Union — have agreed to reduce their carbon output significantly by 2020.
Studies like the one led by Betts can quickly and effectively tell us if the things we are doing to combat climate change are working. “As countries start to implement reduction plans,” Poulter says, “we can monitor the effects those reductions are having.” (VOA)
Fashion's biggest extravaganza, The Met Gala 2021, made a comeback with a vengeance after a skip in 2020 due to the pandemic. The theme for this year's gala was 'In America: A Lexicon of Fashion', and as usual in attendance were a long list of celebrities including actors, musicians and sportpersons. Many fashion houses and celebrities chose to dazzle with the dark side of fashion as capes, leather, face masks and all kinds of drama unfolded at the event, as black ruling the red carpet with its darker vibe.
Met Gala regulars like Jennifer Lopez, Rihanna, Sharon Stone, Emily Blunt, Irina Shayk, Gigi Hadid and the Kardashian-Jenner siblings were spotted alongside debutantes like 18-year-old British tennis star Emma Raducanu who recently won the US Open, Rose Leslie from 'The Game of Thrones', gymnast Nia Dennis and Justin and Hailey Beiber who walked the Me carpet together for the first time.
The event is hosted by Vogue's Dame Anna Wintour and is held annually at The Metropolitan Museum of Modern Art in New York City. Here's a look at some of the stars who chose to walk on the darker side:

Many young and middle-aged people today are dying of sudden heart attacks. Studies show that cardiovascular diseases (CVD) strike Indians a decade earlier compared to their Western counterparts. Why is this happening? How can we prevent it? Are we just focused on post-heart attack action? Or should we be focused more on prevention?
Luke Coutinho, Holistic Lifestyle Coach -- Integrative and Lifestyle Medicine shares an input that could prevent heart attacks at a young age:
Cholesterol is not the culprit, inflammation is: Many people believe that high levels of cholesterol and triglycerides are the sole culprits behind their heart attacks. The main reasons behind most heart attacks are inflammation and oxidative damage in the heart, blood vessels, endothelial lining, arteries, and more. While maintaining healthy cholesterol levels is important, we cannot blame heart attacks on cholesterol levels alone. What then can you do to keep inflammation in check and your heart strong? Adopt simple lifestyle changes.

Switch from ordinary substandard cooking oils to cold-pressed oils: Refined oils are highly inflammatory and a threat to your heart. Using refined oils just to save some money isn't a wise idea. Choose the right quality and quantity of oil to boost your heart health. It might cost you a few extra bucks, but remember, your health is not a cost but an investment.

Switch from a sedentary lifestyle to an active one: Even if you don't engage in a full-fledged workout, just stay active. Walking and yoga are the most effective exercises. Choose fun workouts that you enjoy -- dancing, aerobics, Zumba, swimming, whatever it is, but keep that body moving. People who live a sedentary lifestyle are at high risk of heart attacks. Having said that, over-working out with little orno rest or recovery period is equally harmful. So, figure out the adequate level of activity your body needs and stick to it.

Don't take matters to your heart: Before renting out your heart space and mind space to a person, event or experience, ask yourself if it is worth it. While stress is inevitable, what sets a happy person apart from a stressed person is their capacity to diffuse and navigate stress and see things in a positive light. You can continue attending stress management classes and workshops, and while all of them can help you feel better for some time, the real change happens when you start changing your perspective towards life and how you relate to stress.Learn to accept and let go. Build your self-worth, create a beautiful inner world, reflect inwards, and allow these teachings to slip into your daily living.

Fix your sleep routine: There is nothing cool about pulling an all-nighter to work or socialize more. Your body only cares about survival. Remember, your sleep is your heart's free drug. The chronic deprivation of it can increase your risk of a heart attack. Your heart is a muscle that needs recovery. Lack of sleep increases your insulin resistance and makes you more prone to type-2 diabetes and a gamut of metabolic conditions. So, adopt a fixed sleeping schedule and sleep deep.

We cannot wait for more misfortunate incidents to realize the importance of lifestyle and start prioritizing it. We must wake up and work towards prevention. Many of us may go through heart disease later in life, no matter how well we exercise or eat clean. So, identify risk factors and work towards tackling them. Even if one of your risk factors is genetic predisposition and there is nothing you can do about it, you can still alter your lifestyle. Our intelligent human body was designed to fix and heal itself. The least we can do is invest in it and help it do its job effectively. Lifestyle can help you bridge this gap.

When it comes to burgers, its not just the patty that makes it all worthwhile... one can't forget the cheese or the crunchy lettuce either. In India, McDonald's ensures their burgers use the freshest produce, which means that don't use any ordinary lettuce. The iceberg variety was first introduced in India by McDonald's, as early as the 90s, at a time when not many people were familiar with lettuce and used cabbage instead. Lettuce is a key ingredient known for its crunch, its odourless and is ideal for salads, sandwiches and burgers.
The fast food giant collaborated with local Indian suppliers and pioneered the local production of iceberg lettuce in the country. Their lettuce undergoes 30 quality and food safety checks. After harvesting, the lettuce is pre-cooled to a temperate of below 40C at the farm gate to maintain its freshness. It is then transported in refrigerated vehicles to the world-class processing plant where it is shredded to a measured length and width and then washed and cleaned thoroughly before being vacuum-packed.

Today, the lettuce that goes into your favourite burger is produced at a pristine height of 10,000 feet under the rain shadow areas of the Himalayas in the Manali and Lahaul districts. Over the last 15 years, the farm base that produces lettuce for McDonald's menu items has grown from 5 acres to more than 100 acres. The process for growing lettuce is very rigorous and thoroughly monitored starting with the selection of seed variety, nursery production, fertigation, integrated pest management and post-harvest technology. Over the years, the company has continued to engage with local suppliers in good agricultural practices, meeting the Gold Standards of food safety and hygiene. It has transferred global best practices in irrigation, pest control, seed selection benefitting nearly 250 small and marginal farmers across the country. These practices ensure the right conditions for the iceberg lettuce to grow.
With over 60 years of experience in developing the best quality standards for the industry to follow, it continues to build and strengthen the foundation of good food practices and knowledge transfer, while serving great-tasting menu items at a value to its customers. "At McDonald's, we are committed to offering great tasting food using high quality ingredients to our customers. To offer the best to our esteemed customers, we take extra care in ensuring that the highest levels of hygiene and food safety are maintained at every step of how our food is produced, where its ingredients are sourced from and how it is processed . We are committed to responsible sourcing and supporting farmers community growing lettuce for us." said Rajeev Ranjan, COO, McDonald's India , North and East.
