Global Warming is Causing Cold Spells

Extreme Weather has always Occurred

Global warming does not cause an increase in the frequency or severity of cold weather events such as colder than normal winter outbreaks of “The Polar Vortex”. The United Nations Intergovernmental Panel on Climate Change (IPCC) reports it is “very likely” that there have been fewer cold days and nights in recent decades.  The U.N. IPCC reports it is “virtually certain” that there will continue to be decreases in cold temperature extremes.

Climate Change is Causing Accelerated 21st Century Surface Warming

Most Observed Warming is Natural

Almost half of the global warming in the 21st century is due to El Niño events

A major uncertainty in figuring out how much of recent warming has been human-caused is knowing how much nature has caused. The IPCC is quite sure that nature is responsible for less than half of the warming since the mid-1900s, but some climate scientists, politicians, activists, and various green energy pundits go even further, behaving as if warming is 100% human-caused.

U.S. Heat Waves

Heat Waves are Not Increasing

Claims of increased U.S. heat wave frequency and length are often misleading because they ignore the worst heat waves the U.S. ever experienced in the 1930s, even though records are publicly available. According to the best state-of-the-art temperature data available, there has been no sustained increase in maximum temperatures in the United States since 2005. 

U.S. Temperatures are rising dramatically

There are No Real Warming Trends in the US

There has been no significant warming in the United States since at least 2005.  Any claimed recent warming and impacts at specific places in the United States are isolated and indicate random variation rather than long-term warming.

We Need to Limit Global Warming to 1.5 Degrees C°

These Temperatures Are Not Abnormal or Dangerous

Climate alarmists (and the IPCC) say we need to limit global warming to 1.5°C above pre-industrial times to avoid disastrous consequences, but data show we have already reached such temperatures.European temperature data show temperatures began rising about the year 1890.

Note that this was before the large modern rise in CO2 emissions, and as shown by the U.N. Intergovernmental Panel on Climate Change, catastrophic predictions of extreme climate change have not come true.

Is The US surface Temperature Record a Reliable Indicator of Warming?

Too Many Stations are Compromised And Not Maintained

A study in 2009 showed that almost 90% of weather stations used to measure climate in the USA have been compromised by urbanization effects. Some stations were in pristine rural condition years ago when first established, but now have become surrounded by asphalt, concrete, and builds which act as heat sinks, and energy sources such as air conditioner exhausts which raise local temperatures at night.  Another 2015 study1 showed that almost half of the climate warming trend in the USA disappears if data from stations that have not been compromised is used.

Measuring the Earth’s Global Average Temperature is a Scientific and Objective Process

Surface Temperature Records are Distorted

Broad areas of the world don’t have any temperature measurements being made, now or in the past. In order to get a global temperature average, scientists interpolate data from surrounding areas that have data.  When such interpolation is done, the measured global temperature actually increases.

El Niño

El Niño’s are a natural phenomenon and of little concern

El Niño events in the Pacific Ocean are natural patterns that have been going on for millions of years. It’s true that El Niño events in the 21st century have had some very strong warming spikes. However, if you remove the effect warming El Niño events in the climate record, the amount of warming since 2000, you find almost half of the global warming in the 21st century is due to El Niño events.

Urban Heat Islands Do Not Exaggerate Global Warming

 Urban Heat Islands Distort the Temperature Record

The majority of U.S. temperature stations utilized for NOAA and NASA temperature records have been compromised by encroachment of artificial surfaces like concrete, asphalt, buildings, and air conditioner exhausts. This creates a substantial false warming trend that is responsible for almost half of reported U.S. warming. When only pristine temperature stations are used, warming trends are quite minimal.

We are in the ‘Hottest Ever’ Period Due to Climate Change

Earth’s hottest periods occurred before humans existed.

New studies sponsored by the Smithsonian Institution show that Earth experienced much warmer periods in the past than we have today.  In the recent past global mean temperature appears to have risen by as much as 9-14°F (5-8°C) to an average temperature as high as 73°F compared to the 20th century global average of 56.7°F.
