Debunking Global Warming Misconceptions Part II -- Actual Temperature Data Shows Long Term Cooling Trend

Myth: Climate realists look at a single cold winter's day and use that to dismiss global warming.

When climate realists say, "So much for global warming," they're saying it based on long term trends. They're not basing it on single incidents during a specific season... unless they're talking about those incidents collectively over time.

For example, we've had two cool snaps in North America during the summer of 2014. The polar air mass made the height of summer feel like late fall. This normally doesn't happen. Those cool snaps dropped average summer temperatures. 

This appeared to be a continuation of the cold snap events of the previous winter. The following winter also set records.

Many of those, that advance this myth, take a single record hot event as "proof positive" of man-made global warming. 

Many pro-global warming debaters tend to emphasize the impacts of summer heat waves in relation to the climate debate. Many of the same groups attempt to isolate cold snap events from the climate debate.

A few years ago, I saw a statement on a weather website. 

During the time, half the country was under a warm air mass. The other half was under a cool air mass. Records were being set under those air masses. However, they reported it something like this, "record heat set in ____ wintry weather in ___." 

That wasn't balanced reporting. They could've stated something like record heat in one area and record cold in another area. Or, they could've said "summer like" in one area and "winter like" in another area.

The bias toward the man-made global warming argument was evident in that headline.

In reality, records favoring the cold and warm ends of the temperature extremes are set each year. This includes record highs, record lows, record low highs, and record high lows. The momentum is shifting more in favor of record cool and cold temperatures throughout the year.

There are those who will take the record highs and try to use that as an argument that the world is getting "warmer." This same group ignores the more impressive record cold/record cool temperatures and weather.

Myth: Increased storms and droughts are a sign of man-made global warming

Climate change has always been around, at least since the atmosphere facilitated climate change. It's not restricted to Earth. Evidence of climate change has been observed on Mars. 

Unfortunately, the term "climate change" has been hijacked as an alternative term for "global warming." Momentum for this term change accelerated as evidence contradicted man-made global warming.

The increasing volume of evidence makes it easier to debunk global warming. Those that advance the man-made global warming theory attempt to shield themselves from "being wrong."

After all, when "the majority of the masses" see that the pro-global warming debaters are wrong, the latter could say that the climate did, in fact, change.

Increasing storm intensity, and increased temperature contrasts, are symptoms of a mini ice age. The larger the difference between meeting air masses, the better the chances of violent storm reaction.

Air masses headed south, to meet warmer air, have trended towards being cooler/colder each year. This increases the temperature difference compared to the air mass flowing north from the Caribbean. This contributes to more energetic and violent storm activity each year.

Myth: Climate realists just use recent years to argue global cooling; they "ignore" the graph that started in the 1970s and earlier.

When climate realists use a graph, they use one that spans decades, even centuries. They also use the one that resulted from the ice core samples pulled from the Greenland and Antarctic ice sheets. This spans approximately 400,000 years.

The global warming group emphasize the graph running from the 1970s to present. Or, they use one where the data was manipulated. This manipulation increased temperatures in the present while suppressing temperatures prior to 1970.

This provides a phony image of temperatures rising in conjunction with human industrial activity.

Climate realists utilize raw data graphs. These raw data graphs indicate natural rises and decreases in temperatures that follow a pattern.

Raw data indicates a declining overall trend in temperature starting in the 1920s. With the 19th century's climate included, these graphs show an increase in global temperatures from the mid-19th century until the 1930s.

Temperature trends declined from the 1940s to the 1970s. They increased from the 1970s to the 1990s. Since then, it has been getting cooler.

Both long-term, and short-term, trends show a world that's cooling down, not warming up.
