Scientific evidence:

     Scientists have long been analyzing data to try to determine the severity of climate change and trying to make accurate projections for the future. However, due to inaccurate measurements, and computer limitations, and the fact that some things were not incorporated, dynamic predictability is impossible. The predictions are unreliable. 

​

     As well, many current climate models ignore the "forcings and feedbacks" of our planet.

     Radiative, or climate forcing is the difference between the energy of sunlight absorbed by the Earth and energy radiated back into space. Variations in solar activity drive the climate, and current climate models often fail to account for that; solar-controlled climate change epochs include the Medieval Warm Period, Little Ice Age, and Early Twentieth Century Warm Period (NIPCC, 2013). The Sun may have contributed as much as 66% of the observed twentieth century warming, and perhaps more (NIPCC, 2013). This means human actions aren't causing as serious actions as we though. 

​

     Feedbacks on the climate refer to the negative feedback loops that reduce the effect of climate change. Negative feedback is when some function of a system's output is fed back into the system, reducing the impact of the system. In other words, negative feedback is a buffer to the system, keeping it closer to equilibrium. As an example, agriculture accounts for nearly half of nitrous oxide emissions in some countries. Being a greenhouse gas, there is concern that enhanced plant growth (due to more carbon dioxide) might increase the amount of nitrous oxide and its warming effect. However, field research has shown nitrous oxide emissions will likely fall as carbon dioxide concentrations and temperatures rise, indicating negative climate feedback (NIPCC, 2013). 

​

     There is plenty more evidence opposing climate change. Studies have shown that carbon dioxide levels and temperature do not coincide; in fact, carbon dioxide level changes lag behind temperature changes by centuries. Some studies have provided evidence that Antarctic ice is growing in mass instead of shrinking, contrary to many beliefs. Finally, during the Carboniferous Period 300 million years ago, average global temperatures were around 20 degrees Celsius, nearly 6 degrees higher than the modern average! However, during the Carboniferous, life was flourishing and terrestrial organisms were able to grow to massive sizes (dragonflies had wingspans of over 75 centimeters!). Just a few degrees higher should pose no problem looking back at the past. 

​

Non-scientific evidence:

     Even non-scientists can tell that climate change is not happening from the plethora of evidence available.

 

     If global warming is happening, it is only reasonable that temperatures around the globe are rising, which isn't true! In fact, below-average temperatures are common in many countries on a day-to-day basis. Anyways, global warming is nothing new. Looking around us at a world not under meters of ice, it is obvious that the temperature has been consistently rising since the last Ice Age 20 000 years ago. 

     As well, our current prediction models are terrible. Climate scientists expect us to believe their decades-long predictions about worldwide climate when they can't even predict the weather next week with confidence!

 

     The rising temperatures we have observed can be linked to the urban heat island effect with the growing trend of urban sprawl. An urban heat island is a metropolitan area that is significantly warmer than its surroundings due to human activities; many weather stations are in close proximity to urban areas, making the results inaccurate. 

​

     Even the recent winner of the 2016 American election and current President-elect, Donald Trump, has expressed his opinion against climate change. The concept of global warming was created by and for the Chinese in order to make U.S. manufacturing non-competitive (Trump, 2012).
