So not only were the levels of CO2 in our atmosphere the highest recorded in more than 800,000 years, they were also in excess of the 350 parts per million (ppm) “cautionary threshold” put forth by Dr. James Hansen and other climate scientists in 2008. In fact, CO2 measurements on Mauna Loa in the spring of 2014 exceeded the “extreme danger” Cclimate Cchange threshold of 400 ppm from which some scientists have said that recovery is not possible.
Because they were being ignored, Native Hawaiians protest to not accurately following procedures before approving the Thirty Meter Telescope to be built on Mauna Kea. Pluralism is absent in democracy.
Whenever someone thinks of CO2, they think of global warming. They are reminded of Al Gore and his stance on global warming and they automatically think it is true. He has a lot of evidence to back up his theory about how global warming exists and that it is the reason animals are going extinct and also why the climate is changing. Well these facts are wrong and there is evidence to prove it. Global warming is not real and the Earth might even be in a cooling period. There so many reasons to blame people for the epidemic of this false global warming. CO2, a naturally produced gas absorbed by oceans and trees could not be the reason, so what could? Well, nothing can, none of man’s efforts to control the climate will
The rapidly increasing amount of carbon dioxide may be one of the factors that cause climate change. As Hillman states, “Concentrations of carbon dioxide in the atmosphere are increasing, and have done so since the Industrial Revolution.” An atmospheric CO2 concentration, research shows that there is a dramatic increase from 280 parts per million (ppm) in 1750 to 373 ppm in 2002, a rise of the third. Furthermore, the linear chart demonstrated the trend of annual global CO2

Al Gore includes several examples of what impacts the rising co2 has caused in his speech. For example, he explained that the extreme heat wave in Europe in 2003 killed an estimated 20,000 people. (302). While this is good use of pathos by how damaging the climates current state can affect both humans and our environment, he does not offer solid evidence to back this claim that it was the co2 that caused the heat
Over the years Carbon Dioxide has been significantly increasing from human activity. CO2 has a concentration of about 400 ppmv (parts per million volume). Its concentration in the atmosphere was about 280 ppmv before the Industrial Revolution, now it has increased immensely to about 380 ppmv in 2006. Many have said Carbon Dioxide has been the main reason or cause of global warming; saying that if we produce too much of this greenhouse gas it can create a global climate change. Even though carbon dioxide affects the temperature of the atmosphere it also affects the acidity of water specifically in the ocean.
Main Point - Despite the fact that a specific amount of carbon dioxide (CO2) happens naturally in the Earth's atmosphere, there are many human activities that boost the levels of the greenhouse gases causing it to be harmful to Earth`s climate.
In Brian Sussman’s argument against man made global warming, he says that CO2 is not as dangerous to our atmosphere as scientists say. I agree, we need CO2 to live, which is fact. However, at the rate humans are pumping carbon dioxide into the atmosphere it is offsetting the balance. The plants, trees, and oceans cannot keep up, and cannot absorb the amount of CO2 we releasing into the atmosphere. This disrupted balance in the environment makes the CO2 dangerous. Going back to the Vostok (Antarctica) Ice Core Record, as CO2 levels rose, so did the global temperature.
The study shows that any release of carbon dioxide is happening in a very gradual manner that is taking far longer than originally was thought would occur, which is good news for the Earth’s environment.
Carbon Dioxide is a dangerous, poisonous gas, carbon dioxide is a greenhouse gas that is appearing more in the atmosphere. The human body and most other species on earth need oxygen to live and breath. Without enough oxygen in the air we would suffocate and so would most other spices. Now there is a way to reverse the amount of CO2 in the air. The answer to this issue, is plant more trees! Trees and other vegetation take in CO2 and convert it to oxygen. Not only could we have CO2 levels on the rise but another big kill around the world is cancer is In 2012, there were an estimated 8.2 million deaths from cancer in the world. Cancer is the second leading cause of death around the world. Im
Secondly, together with deforestation of the planet, the burning of fossil fuels is contributing to a measurable increase in the concentration of carbon dioxide in
Climate change or colloquially known as global warming, now pose a new threat to civilization as the levels of greenhouse gases (GHG) are soaring to new levels. The most significant contributor to greenhouse gasses would be Carbon Dioxide (Co2). The levels of Carbon Dioxide (Co2) gas have risen to levels civilization has not seen before. As such, the effects of these levels are not known to civilization as data gathered from the ice cores drilled in the Antarctica only shows data up to 650,000 years ago. However we can conclude that present CO2 concentrations are higher compared to any time in the last 650,000 years (IPCC 2007). Current carbon dioxide concentrations are hovering around 389 parts per million (ppm) as of September 2011,
The atmosphere report, discharged today (Nov. 3), illustrates the present and future impacts of worldwide environmental change, from ocean levels that could ascend by as much as 8 feet (2.4 meters) by 2100, to more-visit warm waves and other outrageous climate occasions. It is glaring difference an unmistakable difference to environmental change positions taken by President Donald Trump, who has run from calling it a fabrication to stating he had a "receptive outlook" about whether the human-caused environmental change is really
If the atmospheric carbon dioxide levels reaches 560 ppm it will cause a chain reaction of events that will negatively impact our planet. The weather will vary, being much warmer in some areas and significantly colder in others. This change in weather will lead to events such as, glacier and permafrost melt, ocean acidification, more drought, biodiversity losses, and coastal erosion. Permafrost is found in northern areas and when it melts in causes the land to sink and change shape. Additionally, when glaciers melt, along with water expanding from warmer temperatures, it causes the sea levels to rise. Low laying coastal communities will flood and some will become completely submerged. Also, with severe weather changes species will not be able
• Carbon dioxide (CO2) is a greenhouse gas that warms the atmosphere. • Since pre-industrial times, atmospheric CO2 concentrations have increased from about 280 parts per million (ppm) to over 380 ppm. Current concentrations of CO2 and other greenhouse gases are unprecedented in at least the last 650,000 years, based on records from gas bubbles trapped in polar ice. • Independent measurements demonstrate that the increased CO2 in the atmosphere comes
