1. How do we know CO2 levels are changing?
Tip: use at least 3 different sources of evidence that show evidence of changing CO2 levels.
We know CO2 levels are changing from a variety of clues. The ability to see the earth on Antarctica in some parts in a clear indication that the global temperature is rising and also that there are in fact more greenhouse emissions as a result of this, due to decaying biomass. More evidence of a significant change in CO2 emissions was when a group of scientists drilled into a section of Antarctic ice and tested the carbon caught in oxygen sockets and showed the changes in carbon over 40,000 years.
2. What causes natural changes in CO2?
Tip: think about the carbon cycle and seasonal changes.
There are many

How much are we changing levels of CO2?
Tip: use 3 different data sources so that you are confident of your values.
We, as a species, are altering levels or carbon dioxide dramatically. According to NASA, concentration levels of carbon dioxide haven’t been as high as they are now for over 1,000,000 years and that the rate of change CO2 levels in the past five years is alarming.
5. How do changes in CO2 affect us and our environment?
Tip: consider the different effects of increased CO2 on global climate, weather and the oceans.
Changes in CO2 are affecting us and our environment in many ways. the most predominant effect of carbon dioxide changes is on the weather and oceans. Unpredictable heat waves are occurring in unforeseen parts of the world (i.e. Europe) and global temperatures as a whole are rising. The rise in the temperatures can not only affect us but the flora and fauna around us. With hotter temperatures, some plants and animals may be unable to adjust which would result in a chain reaction. Heat is affecting the oceans as well and many long standing glaciers or ice shelves to melt and alter the oceans temperature, levels and salinity. These, resultantly, are causing disruptions to the thermohaline conveyor and are effecting islands or seaside town as the water level
Climate Change- Climate is a long term change in the Earth's weather, especially due to an increase in the average atmospheric temperature. According to research, it was discovered that the Earth's temperature rose by 0.6 degrees Celsius (C) and predicted that the sea surface temperature may rise by up to 1 degrees C over the next 50 years. Unfortunately, carbon dioxide and methane gas levels are the highest they have ever been for the last 420000 years. These two gases with water vapour, nitrous oxide and halocarbons create the five predominate greenhouse gases, effecting the environment greatly. Furthermore, it is evident that an average person release 4 metric tonnes of carbon dioxide per year. Due to this fact, carbon dioxide
Since Earth is responding to temperature changes. Scientist are trying to figure out how the Earth is reacting. The Earth’s CO2 levels are like the Pliocene epoch. The Pliocene temperature back then was 19 degrees Celsius higher than it is today. Scientists believed that the climate change affected the environment.
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.
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
Today, atmospheric CO2 concentration has nearly increased by 25 percent, and the global temperature has risen by nearly 1.25 degrees as reported in 2014 (U.S. Global Change Research Program, 2014), as part of a continuous rise since the 1800s. This may seem small but are having a huge effect on the Earth and causing global warming, and in turn, climate change. These changes are predominantly blamed on humans, through actions such as fossil fuel consumption, deforestation, and increased agricultural production and
Ever since the Industrial Revolution, humans have continuously been putting CO2 into the atmosphere. CO2 is a greenhouse gas, which means it traps heat and energy from the sun and keeps it in the atmosphere. An excess in greenhouse gases in the atmosphere leads to too much heat being trapped in the atmosphere. The trapped heat then causes the global temperature to increase (global warming). Humans continually putting CO2 in the atmosphere has caused global warming.
Human beings have increased the CO2 concentration in the atmosphere by about thirty percent, which is an extremely significant
. In unit 2 we learned that climate change is caused by CO2 (Carbon Dioxide).This layer of greenhouse gas is trapped into the atmosphere and increases the thickness of the layer. As a result it rises the Earth’s temperature warmer and causes climate change. The CO2 is caused by human activities such as pollutions and burning fossil fuel. The risk of climate change is extremely high such as loss of the major ice sheets and sudden changes in the
Anthropogenic activity has led to greatly increased emissions of greenhouses gases. Increased temperatures, acidification and stratification are all affected by increased carbon dioxide (CO2) concentrations. These symptoms of climate change have direct and indirect effects on to marine ecosystems, all of which start at the major primary producers of the oceans: phytoplankton.
(Transition – I will begin by discussing the increase of carbon dioxide into the atmosphere and how humans have made it one of the main causes of climate change.
The concept of climate change has been around for quite a while. The earliest mention of climate change dates back to the 19th century. Swedish scientist, Svante Archenius was the first scientist to study the effect of CO2 on climate. (Rodhe et al 1997)
The main effect of climate change on our oceans, apart from temperature increases, is acidification—that is, an increase in the acidity of the water (or a decrease in its pH). And the cause of this increase in acidity is the same CO2
Climate change has been a widely debated, controversial topic. Some think that it is not an issue that should be payed much attention to. With climate changing being caused naturally and by humans, the climate has been widely changing due to ample amounts of CO2 emissions. Where the burning of fossil fuels is the main source of the human impact. As well as volcanoes being a majority the of natural emissions. Although nature contributes to the climate change humans have more widely contributed to the change of climate abroad.
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
Over the last several decades, climate change has evolved from a polarizing discussion to what will likely be the largest collaborative research project of our generation. While many aspects of climate change are still misunderstood, there is little debate that the concentration of carbon dioxide in the atmosphere is rising at an alarming rate. This rise is considered the main cause behind an increase in global temperature, which has set in motion a chain reaction of climatic events.
