Climate change is real, regardless of whether or not some members of the Republican Party, and some conservatives in general, choose to accept it. According to NASA's website concerning global climate change, at https://climate.nasa.gov/evidence/:
"The planet's average surface temperature has risen about 1.62 degrees Fahrenheit (0.9 degrees Celsius) since the late 19th century, a change driven largely by increased carbon dioxide and other human-made emissions into the atmosphere. Most of the warming occurred in the past 35 years, with the five warmest years on record taking place since 2010. Not only was 2016 the warmest year on record, but eight of the 12 months that make up the year — from January through September, with the exception of June — were the warmest on record for those respective months."
NASA's website concerning global climate change, on the page entitled "The Causes of Climate Change," states the following information:
"On Earth, human activities are changing the natural greenhouse. Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2. To a lesser extent, the clearing of land for agriculture, industry, and other human activities has increased concentrations of greenhouse gases."
NASA's website page entitled "The Causes of Climate Change," further states:
"In its Fifth Assessment Report, the Intergovernmental Panel on Climate Change, a group of 1,300 independent scientific experts from countries all over the world under the auspices of the United Nations, concluded there's a more than 95 percent probability that human activities over the past 50 years have warmed our planet.
The industrial activities that our modern civilization depends upon have raised atmospheric carbon dioxide levels from 280 parts per million to 400 parts per million in the last 150 years. The panel also concluded there's a better than 95 percent probability that human-produced greenhouse gases such as carbon dioxide, methane and nitrous oxide have caused much of the observed increase in Earth's temperatures over the past 50 years."
1,300 Independent scientific experts have concluded a better than 95 percent probability, that human-produced greenhouse gases have caused much of the increase in the Earth's temperatures over the past 50 years. Scientists have come to this conclusion, and some politicians evidently think they know more than scientists who study climate change. One cannot deny that global warming exists, with all of the irrefutable evidence that has been presented by many experts in the field.
16 year old climate activist Greta Thunberg has brought global attention to the issue of climate change. Greta sailed across the Atlantic Ocean on an emissions-free yacht, and spoke at the United Nations Climate Action Summit. View Greta's full speech below. Youtube video posted by PBS NewsHour.
