Human Respiration is Not a Source of Carbon Emissions
That's not a problem. The CO2 that's released by humans (and animals) is produced by metabolising carbon from food, and the food comes from plants that have been grown recently. During their growth, the plants have absorbed an equivalent amount of CO2 from the atmosphere. Even when eating meat, the animals are typically only a few years old and were fed on recently grown plants. In contrast, the cars run on fossil fuels that are hundreds of million years old. 1

Human Respiration is Carbon Neutral
The very first time you learned about carbon dioxide was probably in grade school: We breathe in oxygen and breathe out carbon dioxide. Any eight-year-old can rattle off this fact. More specifically, the mitochondria within our cells perform cellular respiration: they burn carbohydrates (in the example shown below, glucose) in the oxygen that we breathe in to yield carbon dioxide and water, which we exhale as waste products, as well as energy, which is required to maintain...

1 We exhale carbon and that carbon is sequestered in the next plant we eat.

Climate Forecasts vs Projections
"Projections are essential for giving us information on long-term trends, but the timescale is beyond what many policy makers (and the public) consider to be relevant to their decision-making processes. Climate forecasts seek to address this issue by providing information on a shorter term (decadal) that can be used directly to inform policy," he said.
"As climate forecasts improve, they will become more and more important in providing reliable information on what is likely to happen to the c...Forecasts are short-term predictions intended to inform policymakers because projections, which predict the long-term trend, are beyond political scope.

Consensual VS Dissension Approach to Science
The debate surrounding the consensus on climate change is complicated by the complexity of both the scientific and the associated sociopolitical issues. Underlying this debate is a fundamental tension between two competing conceptions of scientific inquiry: the consensual view of science versus the dissension view [24]. Under the consensual approach, the goal of science is a consensus of rational opinion over the widest possible field [25]. The opposing view of science is that of dissensi...Consensus VS debate as it applies to climate change science.

Climate Change Science is Based on an 1896 Paper
Our understanding that increasing carbon dioxide levels in the atmosphere could change the climate is not new. The relationship between carbon dioxide, water vapor, and climate was first laid out in detail in 1896 by the Swedish physicist Svante Arrhenius, who estimated that a doubling of carbon dioxide levels would cause global warming of 4.9° to 6.1°C. In his landmark paper, Arrhenius reported that "a simple calculation shows that the temperature in the arctic regions would rise about 8°...Reference to the original paper that started Climate Change Science.

Deserts Follow Where Man Goes
Very old and wide-spread is the opinion that forests have an important impact on rainfall. ... If forests enhance the amount and frequency of precipitation simply by being there, deforestation as part of agricultural expansion everywhere, must necessarily result in less rainfall and more frequent droughts. This view is most poignantly expressed by the saying: Man walks the earth and desert follows his steps! ... It is not surprising that under such circumstances the issue of a link between fo...Eduard Brückner recognizes the importance of forests in maintaining a healthy climate in the late 1800s.

1890 Statement on Climate Change
The number of hypotheses and theories about climate change are numerous. Quite naturally they have caught the public attention, as any proof of past climactic change points to the possibility of future climate change, which inevitably will have significant implications for global economics. Recognizes it, does not mention Carbon Dioxide, but acknowledges global economic impacts of it.

Evidence of Global Warming in Just the Past 12 Months
Is the climate crisis real? Yes, of course it is. Pause for a moment to consider these events of just the past 12 months:
• Heat. According to NASA, 2010 was tied with 2005 as the hottest year measured since instruments were first used systematically in the 1880s. Nineteen countries set all-time high temperature records. One city in Pakistan, Mohenjo-Daro, reached 128.3 degrees Fahrenheit, the hottest temperature ever measured in an Asian city. Nine of the 10 hottest years in history h...Al Gore summarizes extreme weather events and other natural phenomena as a result of Global Warming from just the past year.
