NASA Scientists Decide How to Best Fight Global Warming – 14 Ways Fight Black Carbon and Methane

NASA scientists determine the 14 most effective ways to fight global warming by reducing methane and black carbon emissions. Countries around the world will need to update and change their infrastructures to yield the greatest results.

After considering 400 different ways to find out which measures to focus on scientists chose 14. Each would help reduce the black carbon, methane, or both. While the entire world will benefit, the greatest agricultural and health benefits will be found in the Middle East and Asia. 

From ENS-Newswire:

Reducing emissions of black carbon and methane into the atmosphere could slow climate change, increase crop yields and prevent hundreds of thousands of premature deaths each year, finds new NASA-led research published today.

UNEP Executive Director Achim Steiner said of the newest findings, "The scientific case for fast action on these so-called 'short-lived climate forcers' has been steadily built over more than a decade, and this study provides further focused and compelling analysis of the likely benefits at the national and regional level."

Dr. Drew Shindell, NASA scientistCarbon dioxide is the primary driver of climate change over the long term, because it remains in the atmosphere 200 to 300 years. The scientists say reducing black carbon and methane emissions would have a more immediate impact because these two pollutants circulate out of the atmosphere more quickly than CO2. Methane has an atmospheric lifetime of about 12 years, while black carbon falls to the ground within a few days.

The new study builds on a United Nations Environment Program-World Meteorological Organization report published in February 2011, also led by Dr. Shindell, which indicated that reducing emissions of black carbon and methane could slow the rate of climate change over the next 50 years.

Methane and Black Carbon Add to Global Warming

Although there are several contributing factors to the world's climate change, carbon dioxide being the greatest concern, black carbon and methane would offer a quick fix to help slow it down. Both add to the formation of ozone and can directly damage plant and human health.

Ways to Fight Black Carbon
  1. Install filters in diesel vehicles
  2. Keep high-emitting vehicles off the road
  3. Upgrade boilers, incinerators, and cooking stoves to cleaner burning types
  4. Install more efficient brick production kilns
  5. Upgrade coke ovens
  6. Ban agricultural burning

Black carbon, or soot, is expelled through the process of burning biomass, such as manure or wood, and fossil fuels. In addition to being physically harmful to humans, respiratory and cardiovascular diseases are common, it falls from the atmosphere covering everything in black dust.

It is most noticeable on snow. That black, dirty snow you see a few days after it fell is fallen carbon particles. It looks disgusting and it's hurting our environment.

When the soot covers the snow it blocks its reflective qualities. Instead of reflecting sunlight, it absorbs it. Carbon absorbs the radiation from the Sun adding to global warming. It can also cause rainfall patterns to change.

Ways to Fight Methane Gas
  1. Capture escaping gas from coal mines
  2. Capture escaping gas from oil facilities
  3. Capture escaping emissions from natural gas facilities
  4. Reduce leakage from long-distance pipelines
  5. Prevent city landfill emissions
  6. Update wastewater treatment plants
  7. Aerate rice paddies more
  8. Limit emissions from manure on farms

Methane is colorless and flammable. Not only is it a majorly potent greenhouse gas adding to the climate change, methane is dangerous. In addition to typically being cast off of landfills as the trash is decaying slowly, methane is being emitted from the ocean floors and is trapped under the arctic ice. 

As global warming increases and glacier ice melts, more methane will be released into our atmosphere. It's a harmful and constant cycle.

Conclusion: Not a Complete Solution

Will this solve global warming? No, but it will slow it down immensely. With such short atmospheric life spans black carbon and methane will be reducing their effects every year, carbon every day. Once under control scientists can figure out what to do with carbon dioxide. Growing hemp could help.

Hemp Could Help Solve Global Warming

Currently, the cultivation of hemp is illegal in the United States. To make a long story short, several powerful businessmen in the 1920s and 1930s saw hemp as a competitor to their multi-million dollar businesses and corrupted the country with massive propaganda. Fueled by lies and racism the country was misled into making it illegal, fearing it would create murderers and rapists. (Seriously.) 

With the help of Harry Anslinger, at the time the head of the Federal Bureau of Narcotics, and congress the United States pushed their agenda across the globe in getting hemp banned. Unlike the alcohol prohibition that was ended, the hemp prohibition has continued for over 75 years.

Why use up the forests which were centuries in the making and the mines which required ages to lay down, if we can get the equivalent of forest and mineral products in the annual growth of the hemp fields? – Henry Ford

Hopefully hemp will be allowed to grow in the United States again as it would be able to end our dependency on fossil fuels. It also takes in more than 4 times the amount of carbon dioxide compared to trees.

In essence the many benefits of hemp would transform global warming. Would it solve the problem? It's unsure, but this quickly growing plant would be a great way to start. We'd love to see what would happen.

How to Solve the Global Warming Problem? Scientists Found the Solution to Global Warming.

Global warming. Everyone knows about it, although not everyone believes it. For those that think the earth is warming up and it's causing massive environmental changes they generally have one question. The question of how to solve global warming has been a concern for many people as the effects become more apparent with icebergs melting. 

Scientists believe they found the solution on how to solve the global warming problem. But to understand the solution, we must first understand the problem.

What is global warming?

​For a quick explanation of climate change, the atmosphere is being loaded with several harmful greenhouse gasses, like methane. Methane is the potent greenhouse gas created when biological waste decays. It's often found around landfills.

The dangers of methane gas is that it's up to 25 times more harmful for global warming than carbon dioxide. As the dangers of methane gas increases, from landfills and the ocean floor, it raises the temperature of the atmosphere in the tropical regions.

Scientists Think Humans Are Responsible for Global Warming

In the last century, the temperature of our planet has risen uncommonly fast, about 1.2 to 1.4 degrees Fahrenheit. The 10 hottest years in recorded history have occurred since 1990; 1998 was the hottest, 2005 was second. Many scientists believe that human activity is responsible for the recent trend upwards.

What is the solution for global warming?

Stop focusing on the main culprit in causing global warming and go after the quick fix. Does that make sense? Basically the main greenhouse gas that is causing global warming is carbon dioxide and that is the greenhouse gas that world leaders have worked the hardest in trying to control.

However, scientists are saying to concentrate on the more health hazardous greenhouse gasses, methane and soot. By focusing efforts on these instead of carbon dioxide we will make the biggest difference in overall global warming and give us more time to figure out how to stop all greenhouse gasses.

From NYDailyNews.com:

Two dozen scientists from around the world ran computer models of 400 different existing pollution control measures and came up with 14 methods that attack methane and soot. The idea has been around for more than a decade and the same authors worked on a United Nations report last year, but this new study is far more comprehensive.

All 14 methods — capturing methane from landfills and coal mines, cleaning up cook stoves and diesel engines, and changing agriculture techniques for rice paddies and manure collection — are being used efficiently in many places, but are not universally adopted, said the study's lead author, Drew Shindell of NASA.

If adopted more widely, the scientists calculate that would reduce projected global warming by 0.9 degrees Fahrenheit (0.5 degrees Celsius) by the year 2050. Without the measures, global average temperature is projected to rise nearly 2.2 degrees Fahrenheit (1.2 degrees Celsius) in the next four decades. But controlling methane and soot, the increase is projected to be only 1.3 degrees (0.7 degrees Celsius). It also would increase annual yield of key crops worldwide by almost 150 million tons (135 million metric tons). 

Conclusion: Is this a temporary fix?

Although this is a small fix for the present, it's a start. It makes sense to focus on the most harmful greenhouse gasses first, methane and soot, before concentrating on the carbon dioxide. 

Scientists have high hopes that this will provide a quick fix to give the world time to fix the many environmental dangers that have become so engrained in society as a whole. Of course, it would be best if all the problems affecting climate change were done at the same time, this might make it seem more feasible for the world. Baby steps in the right direction are better than standing still with a problem.

Scientists Think Humans Are Responsible for Global Warming

Global Warming is the increase in the average temperature at the Earth's surface and in the oceans. The atmosphere is collecting carbon dioxide and other air pollution every day. The more being collected, the more of the Sun's heat it traps causing our planet to warm up.

This process is known as Global Warming. In the last century, the temperature of our planet has risen uncommonly fast, about 1.2 to 1.4 degrees Fahrenheit. The 10 hottest years in recorded history have occurred since 1990; 1998 was the hottest, 2005 was second. Many scientists believe that human activity is responsible for the recent trend upwards.

Earth on fire from global warming

The largest U.S. source of carbon dioxide pollution is thanks to our many coal burning power plants, producing an astronomic 2.5 billion tons every year. The second largest source is our automobiles, creating nearly 1.5 billion tons of carbon dioxide annually. If we continue our lives as we have in the past, the concentration of carbon dioxide, greenhouse gases, and air pollution in our atmosphere will continue to rise. Scientists are predicting an increase of 2 to 10 degrees Fahrenheit by the end of the century.

Although we are unaware of the full-scale impacts the future will hold for our planet, but if current trends continue many Scientists agree with certain consequences. We are already seeing the arctic sea ice shrink before our eyes. NASA has found that it's declined by 10% in the past thirty years. Hurricanes could intensify with the warmer sea surface temperatures. Warmer areas could experience severe droughts. And species that are unable to adapt to the warming conditions could face extinction.

Global Warming 101: National Geographic Environment – Global warming could do more than just melt polar ice. It could change our maps, and displace people from cities and tropical islands.
