1. The climate of the earth is not warming up rapidly

If you look at the HadCRUT3 surface temperature index (https://www.metoffice.gov.uk/hadobs/hadcrut3/)), which is based in the UK, records show warming to 1878, cooling to 1911, warming to 1941, cooling to 1964, warming to 1998 and cooling to 2011. The increase in temperature between 1964 was the same rate as recorded between 1911 to 1941. Numerous satellites, ground stations, and weather balloons show recorded cooling since 2001.

The current warnings of a temperature increase of 0.6 degrees to 0.8 degrees are nothing irregular and fit into the natural rate of the warming recorded over the last few centuries.

The placement of these global weather stations should be taken into account. They are mostly based in so-called heat islands in cities where temperatures are normally higher, and few have been placed in rural countryside locations.

Two teams have corrected the average temperature readings between all the stations and have reduced the reported increase in temperature by half since 1980. Up to today, there has never been any sort of significantly extreme event caused by warming.

There was global warming about a thousand years ago (Medieval Warm Period) – it’s a cyclic matter, no need for alarmism.

2. Reports show that the global climate has been cooling for the past 1000 years and recently, temperatures have skyrocketed

Throughout history, the climate of this planet has fluctuated greatly, many ancient people and religions alike talk about a great flood, which was probably caused by the melting ice caps or glaciers. Recorded history tells us of a warm period from around 1000 to 1200 AD, which allowed the Vikings to farm crops on Greenland. This was followed by the little ice age.

Since the end of the 17th century, the average global temperature has been rising at a steady rate, except for the period of 1940 to 1970 in which the climate cooled off, which in turn led to a global panic about global cooling!

Over a century, stratocumulus clouds forming off the coastlines can turn the global temperature up or down by a few degrees, and the “climate models” cannot predict which way it will go. (July 2018 issue of “Science).”

3. The rate of carbon dioxide in the atmosphere has been directly credited to the human species and greenhouse gasses, causing the current warming trend

The carbon dioxide level in the atmosphere has fluctuated due to various reasons over time. Since the industrial revolution, the CO2 levels in the atmosphere have increased on average by roughly 120 parts per million. Most of this is linked to the human cause, and during the current century, the increase is approximately 0.55% per year.

Though there is absolutely no proof that CO2 is the main driver of global warming. As ancient ice core measurements have proven that CO2 levels in the past have often changed after a temperature drop or increase. Solid evidence exists that shows that as temperatures fluctuate naturally through solar radiation and other galactic and local influences, the warming of the surface levels of the planet results in more CO2 being released into the atmosphere.

The ratio of man-made CO2 to natural CO2 on Earth is about 1 to 2400. That means man’s portion is about 2 drops if a 12 ounce glass held Earth’s CO2.

Recent findings show Mt. Katla buried under a glacier in Iceland emits up to 24,000 tons CO2 per day; it’s possible that many more other sub-glacial volcanoes worldwide are dumping much more CO2 into the atmosphere. There are 40,000 miles of volcanically active mid-ocean ridges, of which only a tiny fraction has been mapped. That’s a real big thermal and CO2 output area we know little about.

4. The poles are warming, and ice caps are melting, apparently

Updated data from NASA satellite instruments reveal the Earth’s polar ice caps have not receded at all since the satellite instruments began measuring the ice caps in 1979. Temperatures at the poles have not increased since 2005. In fact, apart from the Palmer Peninsula, the entire Antarctic region is cooling down. Icecap thickness in the arctic and north poles are increasing in size and will continue to do so until things naturally warm up.

5. Computer models are being used to calculate the future impacts of CO2

These computer models are programmed to assume that CO2 is the largest climate driver and that the sun has little effect on the climate. These computer models can be programmed with a large number of variables in order to come to the conclusion that the earth will cool down or warm-up. A computer model is no way to measure anything, as it is purely a matter of who inputs the data for the model.

The sun is a major driver of the climate, with daily additions of solar radiation that are completely random and follow no pattern at all. These computer models do not take this into account and, therefore, do not give a true representation of the actual climate. And as such, they should not be used as a base for such claims.

What I don't really get about climate change is why are they dragging the whole world into it when china and the us are totalling 60%+ of the emissions (china with their mass production and the us with their terrible city/road planning and energy and product waste). The us gets to promise one of the lowest reductions for 2030 and china gets a free pass while everyone else is reducing up to 40%? International treaties are a Fucking joke.

6. The melting of natural glaciers proves global warming?

Glaciers have naturally receded and grown countless times throughout history. Recent glacier receding is simply an outcome of the warming planet after the little ice age of the early medieval period. Scientists have discovered evidence that the ice caps and glaciers have receded and increased in size on numerous occasions throughout history.
https://climate.nasa.gov/news/2882/jakobshavn-glacier-grows-for-third-straight-year/

It is a normal thing for the glaciers to shrink and expand over time. Anyway, this is more driven by precipitation than temperature.

7. CO2 is a toxin?

A lot of people believe this, and it plays a part in many scientific studies from a purely theoretical standpoint. CO2 is just as important as nitrogen to the atmosphere.

CO2 plays a major role in the bringing about of life on earth, it is necessary for plant growth, and in some areas with higher levels of CO2, records show that some tree and plant life can grow at extraordinary rates. The assumption that CO2 is a pollutant is completely false.

8. Global warming apparently will cause storms and extreme weather

These claims are completely baseless. No evidence exists of the weather being affected by global warming on a global scale. Regional variations do occur. Extreme weather can be affected by a large number of variables; things like the jet stream, for example, can change the weather for many seasons in different European countries. Even sand swept up from the Sahara desert can change the climate of the northernmost European nations.

Global warming has no impact on these weather systems. Some argue that global warming will lead to droughts across the world, but if global warming happens the way we are being told, there should be more moisture in the air all around us as the moisture evaporates due to high temperatures.

9. Does global warming cause a shorter lifespan?

Considering that the earth’s climate has been forever changing since the formation of the planet. It didn’t stop just because our human race popped up. Even during our history, the earth’s climate has fluctuated from cold to hot and back again; we do what we have always done, and what life always does, we adapt.

Due to all the major increases in scientific and medical studies, our current lifespan is vastly superior to our ancestors, and this will continue to grow as time goes on.

10. Does CO2 form the largest part of the greenhouse gases?

Greenhouse effect causing gas forms roughly 3% of the volume of the atmosphere. 97% of which is water vapor and clouds, with the remaining percentages being gases like CO2, CH4, Ozone, and N20. CO2 makes up about 0.4% of our atmosphere.

The small amounts of gasses in the atmosphere are capable of retaining the heat from solar radiation, but due to the relatively small amounts of them in comparison to the other 90% of water vapor. That 90% is believed to cause 75% of the greenhouse effect.


At their current levels, if water vapor were to increase just 3%, that would amount to the same level of the greenhouse effect as if CO2 increased by 100%.

11. “The impacts of climate change are expected to act as a ‘threat multiplier’ in many of the world’s most unstable regions, exacerbating droughts and other natural disasters as well as leading to food, water and other resource shortages that may spur mass migrations.”

Regarding food and water supplies, global crop production has soared as the Earth gradually warms. Atmospheric carbon dioxide is essential to plant life, and more it added to the atmosphere enhances plant growth and crop production. Plant growth and crop production also benefit from longer growing seasons and fewer frost events. Global crops set new production records virtually every year as our planet modestly warms.
http://www.forbes.com/sites/jamestaylor/2013/01/16/fortified-by-global-warming-crop-production-keeps-breaking-records/

The same holds true as per objective data for water supplies. As our planet warms, there is a gradual increase in global precipitation and soil moisture. Warmer temperatures evaporate more water from the oceans, which in turn stimulates more frequent precipitation over continental landmasses. This results in enhanced precipitation, which means an improvement in soil moisture at almost all sites in the Global Soil Moisture Data Bank.

If crop shortages, declining precipitation and declining soil moisture cause national security threats, then global warming benefits rather than jeopardizes national security.
