Climate Change 2019: Why We Must Pay Attention to Global Warming

Published

on

The need to pay attention to our impact on the environment was highlighted as far back as the early- to mid-1700s by the French philosopher and writer Voltaire. His quotation mentioned above: “Men argue. Nature acts” is the epitome of the harsh reality of the impact of global warming on the world’s climate.

Climate change: Conferences and resolutions

The world’s first climate change conference was organized by the World Meteorological Organization (WMO), and it was held in 1979 in Geneva, Switzerland. The main topic and raison d’etre for the conference was to discuss “global warming in addition to climate research and forecasting.”

Fast forward to 2018, the most recent climate change conference held in Katowice, Poland and one of the main topics of discussion was still climate change as a result of global warming. This conference focused on the importance of reducing, and ways to reduce CO2 (Carbon Dioxide) emissions to reduce the earth’s temperature via the reduction of the greenhouse effect.

Thus, at this juncture, it is fascinating and critical to note that, in real terms, nothing much has changed between 1979 and 2018. The situation has probably worsened because, in 2017, Donald Trump, forty-fifth president of the USA and one of the world’s largest economies withdrew the USA from the Paris Accord that was drawn up after the 2016 conference.

As a result, it might be logical to conclude that preventing climate change as a result of global warming is not an essential part of the world’s governments. However, this conclusion and viewpoint are juxtaposed 180 degrees to the truth.

Not only is it vital that climate change is managed at a national level of all countries in the world, but the following statement made by Sir David Attenborough at the 2016 conference is an accurate representation of the real challenges facing the earth:

Right now, we are facing a [human-made disaster] of global scale, our greatest threat in thousands of years: climate change. If we don’t take action, the collapse of our civilizations and the extinction of much of the natural world is on the horizon.”

Global warming and the greenhouse effect: The importance of paying attention to the reduction of the greenhouse effect

Succinctly stated, the greenhouse effect is where the heat from the sun’s rays are trapped between the earth and the atmosphere due to high levels of air pollution that do not allow the heat to escape back into the atmosphere.

Therefore, a simplistic conclusion that must be drawn from this statement is that if we do not reduce global carbon emissions, the greenhouse effect will increase exponentially until everything on the earth’s surface cannot stand the heat and combusts, or it dries up and dies, destroyed through dehydration or the loss of body water.

Reducing the greenhouse effect

One of the primary ways to reduce the greenhouse effect is to reduce humankind’s carbon footprint.

What does this mean?

In essence, reducing a carbon footprint means decreasing the percentage of carbon-based gasses into the atmosphere at any given moment. The largest source of carbon-based gasses is caused by the burning of fossil fuels like coal for transportation, heat, and electricity generation.

To further our understanding and insight into the origin of greenhouse gasses, let’s look at the three reasons for burning fossil-fuels individually:

Transportation

Essentially, the transportation sector is based on the need to transport people, agricultural goods, and manufactured products over a given distance. It does not matter what the distance is. Coal and oil are the primary fossil fuels that are converted into combustible substances like petroleum gas and diesel.

Vehicular transport (with the notable exception of the bicycle) is all driven by a by-product of one of the fossil fuels. And, consequentially, carbon-based emissions are released into the earth’s atmosphere.

Heat

According to the American Gas Association, natural gas is one of the most popular consumer-driven central heating mechanisms. In summary, a furnace is installed in a building, natural gas is piped into the furnace which is used to heat air or water, and this hot air or water is forced along pipes or ducts into the building to heat the entire building simultaneously.

Electricity generation

Coal-fired furnaces are one of the world’s most popular way to generate electricity. It is relatively cheap but has one of the highest carbon emission levels, especially when dirty coal is used to generate electricity.

Unfortunately, the cost of shutting down these furnaces and moving across to renewable energy-generation sources like solar power can be prohibitive especially for emerging market countries like countries across Africa, South America, and Asia. Therefore, many countries, including the USA, find it more straightforward and more cost-effective in the short-term to use coal as a primary source to generate electricity.

Final thoughts

From the above discourse, it is clear that global governments, no matter what accords and agreements they sign at the biannual world climate change conferences, do not necessarily have the collective willpower to change from using fossil fuels to renewable energy resources like the sun.

Therefore, finally, global citizens should consider to what extent they are going to get involved in highlighting the absolute necessity of reducing greenhouse gasses immediately. This is not a matter that can be ignored as the future wellbeing (and existence) of the earth is at risk.

Climate Change: What, Why, How?

Published

on

Much has been written about climate change and its impact on the world as we know it. Some of it is on the side of what is commonly termed “fake news,” while other writings are based on reliable, evidence-based scientific facts.

Therefore, the questions that must be asked and answered are as follows:

  • What do scientists say about climate change?
  • How is climate change changing the world’s weather systems?
  • And, what can we do to mitigate or reduce the negative impact of climate change on the world’s ecosystems?

At this juncture, it is vital to note that many studies published in academic peer-review journals indicate that 97% of all climate scientists agree on the definition of climate change as well as the consequences and causes of climate change.

Thus, by way of answering these questions, let’s consider each of these questions individually.

Climate change: A comprehensive definition

The climate.nasa.gov website notes that the phrases “climate change” and “global warming” are used interchangeably. However, there are distinct differences in the meanings.

Global warming is the “long-term heating of Earth’s climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth’s atmosphere.”

Climate change, on the other hand, is the “long-term change in the average weather patterns that have come to define Earth’s local, regional and global climates.”

Global warming is one of the fundamental causes of climate change. However, climate change is not responsible for global warming.

What is the impact of climate change on the world’s weather systems? 

As the definition mentioned above states, climate change is a shift in the world’s current climate or long-term weather patterns. The uncontrolled burning of fossil fuels is a primary causative of global warming.

2019 statistics show that the earth’s surface temperature was the third warmest in history at 0.65 degrees Celsius. The earth’s surface temperature heated up by 0.86 degrees Celsius in 2016, the highest in recorded history.

This increase in the earth’s surface temperate, albeit seemingly small, has had, and will continue to have, devastating consequences including a rise in global air temperatures, which in turn causes severe weather events like heatwaves, droughts, hurricanes, tornados, and tropical storms.

A current example of the rising temperatures is the melting of the sea ice in Nome, Alaska. Dog teams racing in the Iditarod, one of the world’s premier long-distance races, have been stranded for a couple of days about 123 miles from the finish line. This is due to the unseasonably warm weather, heavy snow, and the fact that heavy winds blew waves up onto the sea ice, causing the dangerous overflow. Overflow is where water flows over the frozen ice causing it to crack and melt. When people and animals try and move through the overflow, the underlying ice breaks further, resulting in hazardous conditions.

As an aside, three mushers and dog teams were rescued by the Alaskan National Guard because they ran into deep water on the sea ice just 22 miles from the finish line. The mushers were hypothermic and had crawled into their sleeping bags when they were picked up. The dogs were all healthy and were collected and taken separately to Nome, the town where the finish line is.

What can we do to reduce global warming?

This question has been asked and continues to be asked, and the concise answer is that we need to reduce greenhouse gas levels by preventing the burning of fossil fuels. However, there seems to be a lack of political will by some of the world’s biggest countries, such as the USA and China.

Final thoughts

Until the world chooses to pay attention to and work hard at, the reduction of greenhouse gasses, we seem to be set on the current trajectory facing the consequences of rising temperatures and severe weather events that are linked to global warming.

Climate Change, The World Economic Forum, and Davos: Why Climate Change Matters

Published

on

“Our house is still on fire. Your inaction is fuelling the flames by the hour. And we are telling you to act as if you loved your children above all else.” – Greta Thunberg

Climate-related incidents, including discussions, news, and commentary, make the headlines across the globe daily. Young climate activists like Greta Thunberg are standing up for what they believe is right. In summary, they believe that the time for action is now. And, if nothing is done to reduce the world’s fossil fuel emissions, the world will “burn”. 

Additionally, the Fiftieth annual meeting of the World Economic Forum’s (WEF) at Davos, Switzerland, has just concluded. The WEF was established in 1971 to bring the primary role players, including business leaders, politicians, and cultural leaders together to discuss global concerns that hamper global economic inclusion, climate change, and sustainable development. The goal or aim is the achievement of a cohesive and sustainable world.

According to Klaus Schwab, the founder and executive chairman of the WEF, on its fiftieth birthday, the World Economic Forum is “releasing a new Davos manifesto, which states that companies should pay their fair share of taxes, show zero tolerance for corruption, uphold human rights throughout their global supply chains, and advocate for a competitive level playing field.” It is evident from the above statements that the WEF’s primary focus is economic or business-related. And, the participants gather together annually to discuss “everything economic.”

Climate change and the global economy

Thunberg spoke at the 2020 Davos gathering, highlighting that it is vital for the world to pay attention to the fact that the global climate crisis that the global netizens find themselves in. She continues to insist on a zero-carbon emissions global economy. In her opinion, humankind has passed its cut-off day to lower carbon emissions. She, on behalf of all children, placed a series of demands on the table, including ending all fossil fuel explorations, extractions, and subsidies.

The WEF has also placed its climate change objectives on the table. They have noted that the negative impact of climate change, especially global warming, “poses an urgent threat to economic progress, global food security, our natural systems, and individual livelihoods.

Currently, nations across the globe are encountering the impact of global warming, especially that of rising ocean temperatures. An excellent example of the effects of increasing sea temperatures is what is known as the Indian Ocean Dipole.

In essence, it is a weather phenomenon that relates to the differences in sea temperatures in opposite parts of the Indian Ocean. Current warmer ocean temperatures next to East Africa have resulted in above-average rainfall, floods, landslides, and agricultural crop and local infrastructures in countries like Ethiopia, Kenya, Tanzania, Somalia, and South Sedan. Consequently, a famine warning has been issued for East Africa because of the severe flooding and above-average rains.

On the other side of the Indian Ocean, Australia has experienced and continues to experience, the worst bush fires in recorded history.  The fires are so hot that they caused their own climate ecosystem with Pyrocumulonimbus thunderstorms. These storms are essentially dry thunderstorms with severe lightning strikes that start more fires. The worst fires hit the states of New South Wales and Victoria.

Additionally, these dry cumulonimbus clouds have also permitted the bushfire smoke to reach the stratosphere, which is about 16kms above the earth’s surface. This, in turn, has enabled the smoke to move around the world past New Zealand and South America. Scientists believe that the smoke from these fires will travel right across the globe and end up back in Australia.

Consequently, the WEF’s solution is to promote the private sector and government collaboration to build a global marketplace with the ability to ensure dramatic cuts in global emissions. Finally, the WEF’s global climate initiatives aim to contribute to a platform to help raise the aspiration to and expedite climate change action through “multi-stakeholder partnerships” across the entire globe.

Afforestation And Global Warming: How Is This Approach Playing Out Globally?

Published

on

Over the last decade, global warming and climate change have dominated the talks at major events and conferences. Politicians and global leaders have spent thousands of dollars campaigning the idea of helping combat global warming. As such, afforestation and global warming have been two of the most talked-about topics, debating how the former could mitigate the latter.

Our Earth has constantly been trying to cope with the way humans use natural resources, clear forest lands, cut trees, and contaminate the air, land, and water. The industrial revolution, population bursts, and pollution create tons of permanent damage, resulting in global warming and climate change

In such situations, afforestation has always been seen as a critical solution to global warming, a significant climate change reduction strategy even recommended by the UN. And there is tons of research out there that will tell you just that.

A forest’s role

The idea that planting trees will aid in the cooling of the planet makes logical sense, which is why this idea has grown popular among humans. Everyone has probably heard one person or the other calling the Amazon rainforest the “lungs” of the earth. We know that forests absorb carbon dioxide from the atmosphere, thus acting as carbon sinks.

This would result in the partial offsetting of our own industrial and agricultural pollution. Forests are also known to cause a drop in temperature in their surroundings because of transpiration, as water travels from the roots to the leaves, evaporating into the surrounding air.

205 million tonnes of carbon

4.4 billion hectares is the estimated potential area of land cover in the coming decades, a number that far exceeds the current one. New research predicts that if the whole world were to contribute to a joined planting program, these new forests would have the potential to store more than 205 million tonnes of carbon.

This is about two-thirds of the 300 billion tonnes of carbon that has been released into the atmosphere as a result of human activity since the Industrial Revolution. The research says that this places ecosystem restoration and afforestation as the most effective solution at our disposal to mitigate climate change. It ensures that global warming is reduced due to afforestation.

It’s easy

Tree planting is a solution to global warming that doesn’t require President Donald Trump to immediately start believing in climate change, and it definitely doesn’t demand scientists to come up with technological solutions to extract carbon dioxide out of the atmosphere. It’s something that is available now all over the world.

It’s probably the cheapest solution possible, and it makes it easy for everyone to get involved, reinforcing a common goal for everyone to work toward. Organizations like the World Wildlife Fund (WWF) support people all around the world trying to make a difference. Everyone has the capability to make a tangible impact whether it be through donating money to NGOs like WWF or planting trees on their own. Everyone can make a difference.

Demand vs supply

In today’s day and age, products from trees and forests are in extremely high demand. Whether it be something as simple as a piece of paper or something like a forest-based face cleanser, people want it. However, the problem with this is that the rate at which trees naturally grow in forests is much slower than the rate at which trees in forests are being cut down for production.

This increased demand for tree products has put pressure on companies to obtain them by all necessary means, resulting in added stress on forests because of the endless deforestation. Afforestation is the leading effort in helping alleviate this burden on natural forests by providing a more reliable source of tree products. 

This allows companies to use barren land to replant forests and use those trees to satisfy the needs of the people. Afforestation can be the key to leveling the demand from us and the supply from nature, ensuring that we still have a chance against global warming.

Supplying homes throughout nature

When forests diminish, the wildlife does too. Wild animals suffer the most when humans invade forests, destroying everything in their paths. Today, most of the places humans have built their apartments and stadiums used to be homes for wildlife. 

As human activity continues to expand, the number of wildlife living in unprotected areas dwindles while the number of animals on the WWF’s list of endangered species increases. Unless drastic measures are set into motion, most of these animals will become extinct.
This is where afforestation jumps in the rescue the day. It will aide in ensuring that there will be enough forests for wildlife to thrive in. Instead of forcing animals out of their natural habitats, humans will have another source of trees to extract what they need without affecting the wildlife and encouraging the alleviation of global warming. For this reason, afforestation and global warming are largely connected, with one being one of the best solutions to the other.
