opinion essay

On this essay I will be sharing my personal opinion about the global warming, is it the greatest issue nowadays? is it caused by human action, or is it just a normal earth cycle? if it is caused by humans, how can we stop it? if it isn't, does it mean it is good for earth? All of these questions and more will be answered in my own point of view, and based on different researche I did weeks ago.

Many different webpages and scientists differ when it gets to decide if it is caused or not by human beings, but one thing appears to be certain, it is the most serious issue humanity is facing these days, threatening environments, melting ice capes and rising sea temperature and height, it is also the biggest killer of endangered species due to the destruction of their habitats, such as several species of polar bears, penguins and cold water dolphins. So to the first question, the answer is yes, global warming is the biggest environmental issue today.

A big question in the mind of a good number of people is if global warming is actually caused by humans, because since Dr. Patrick Moore, co-founder of greenpeace said there was nothing to worry about, everyone believed to him. The doctor said that when life originated, the amount of CO2 was about a hundred times larger, yet, didn't mentioned anything about the amounts of oxygen, due it is the unbalance between these two gases that creates the greenhouse effect, didn't talked either of quantities of methane gas present in the current atmosphere, the truth is, over my own point of view, a fault of the human being, not only for our industries, but for our own lifestyle, or can any of us imagine a world without cars, air conditioners, fridges, or even meat? Considering livestock is the biggest producers of methane gas, liberated by bacteria in their stomachs while digesting grass or leaves.

No matter how big our efforts are while trying to blame something else, we have the heaviest responsibility when  it comes to global warming.

There is also the belief in some people, and even in several serious scientists, that globlal warming is caused by the sun storms, this is completely irrational, because the solar activity and the global warming have been going in opposite directions since the last 30 years, another common-said is that global warming is actually good, making death of crops by frostbytes each time more rare, and welcoming longer seasons of summer and spring, witch would allow to produce more than one generation at once, this, is also just a big fallacy, the worst cure against hunger is heat, I believe I don't have to explain the consequences of the drought.

So, on and on examples add, because antartica is not gaining ice, the temperature is not cooling, animals and plants cannot adapt to these conditions changing so fast and it has only been rising temperature since 1998, and as long as this myths continue to un-inform us we will only continue to destroy our planet, unless we start doing all of those silly things we are always told to do to help the environment but we never do, such as, not having too many electronic devices plugged, do not use too much water, to use our cars as little as posible, and not to use "sprays" of any kind, such as deodorants, humidifiers or so many others, as they damage the ozone layer

Well, I do believe that that's enough to state a clear opinion, so, I do believe that global warming is the most serious environmental issue of our time, but I also still have faith that we can turn this to the other way if we could just seriously commit to it.

This page lists the top en environmental issues nowadays 

1. Climate Change

Global warming has been concerning scientists for decades, but Al Gore legitimized the crisis with his controversial film An inconvenient truth. From the melting polar ice caps to catastrophic weather and threatened ecosystems, not only is climate change real, scientists agree that humans are influencing climate change with our production of greenhouse gases (mainly stemming from carbon dioxide and methane). What can you do? How bad is it? Why do so many people still think climate change isn’t real? Is it real? These are just some of the issues worth exploring. The good news is that despite the urgency of the crisis, there are exciting technological developments as well as meaningful lifestyle changes you can make to help.

On the list, global warming is the most relevant issue, which is closely followed by energy, waste, water, and food. Classifying it as the most relevante issue

This page lists 176 myths about the climate change debunked, which of course, Uwont just copy and paste it, but here are some of them

Climate Myth	vs	What the Science Says
1	"Climate's changed before"		Climate reacts to whatever forces it to change at the time; humans are now the dominant forcing.
2	"It's the sun"		In the last 35 years of global warming, sun and climatehave been going in opposite directions
3	"It's not bad"		Negative impacts of global warming on agriculture, health & environment far outweigh any positives.
4	"There is no consensus"		97% of climate experts agree humans are causing global warming.
5	"It's cooling"		The last decade 2000-2009 was the hottest on record.
6	"Models are unreliable"		Models successfully reproduce temperatures since 1900 globally, by land, in the air and the ocean.
7	"Temp record is unreliable"		The warming trend is the same in rural and urban areas, measured by thermometers and satellites.
8	"Animals and plants can adapt"		Global warming will cause mass extinctions of species that cannot adapt on short time scales.
9	"It hasn't warmed since 1998"		For global records, 2010 is the hottest year on record, tied with 2005.
10	"Antarctica is gaining ice"		Satellites measure Antarctica losing land ice at an accelerating rate.

All of the other myths are also explained

This page has the opinions os various heavyweights about the global warming issue, but all of them denying it to be caused by human intervention, i'll put some of their ideas here.

Dr. Patrick Moore, a co-founder of Greenpeace:

“There is no scientific proof that human emissions of carbon dioxide are the dominant cause of the minor warming of the Earth’s atmosphere over the past 100 years,” arguing that “perhaps the simplest way to expose the fallacy of extreme certainty is to look at the historical record.” 

“When modern life evolved over 500 million years ago, CO2 was more than 10 times higher than today, yet life flourished at this time. Then an ice age occurred 450 million years ago when carbon dioxide was 10 times higher than today.”

James Lovelock, a highly respected scientist, predicted in 2006 that: “Before this century is over billions of us will die and the few breeding pairs of people that survive will be in the Arctic where climate remains tolerable.” 

however, he admitted to MSNBC: “We don’t know what the climate is doing. We thought we knew 20 years ago. That led to some alarmist books . . . mine included . . . because it looked clear cut . . . but it hasn’t happened.”

This commentaries not only say it is not human fault, but, that it is a natural process, that will benefit the entire planet, for which, its not even considered an issue.
