Here’s my response to a Washington Post article called “Ocasio-Cortez says the world will end in 12 years. She is absolutely right.”

I know that manmade global warming is real.

I know that as we burn fossil fuels, we increase the concentration of carbon dioxide in the atmosphere, and this makes the atmosphere’s temperature increase.

I am not a denier of global warming.

But I am someone who rejects the ridiculous scaremongering that is going on regarding global warming.

The Washington Post recently published this article, which is called, “Ocasio-Cortez says the world will end in 12 years. She is absolutely right.”

Here’s video of Alexandria Ocasio-Cortez making her statement:

I would now like to propose my own hypothesis: Even if we were to do absolutely nothing to reduce our emissions of carbon dioxide in the next 12 years, our release of carbon dioxide will not cause the world to end in 12 years.

My hypothesis is based on the following four scientific observations:

1) According to this article from Live Science, back when the dinosaurs were alive, carbon dioxide levels in the air were five times as high as they are today. But the world did not end. On the contrary, life thrived, and the world had its biggest land animals of all time.

2) According to this article from the BBC, back when the dinosaurs were alive, global temperatures were so high that there were no polar ice caps. But the world did not end. On the contrary, life thrived, and the world had its biggest land animals of all time.

3) According to this article from the Ontario Ministry of Agricultural, Food, and Rural Affairs, the owners of commercial greenhouses deliberately pump extra carbon dioxide into the air inside their greenhouses. But this has not caused the world to end. On the contrary, it makes the plants inside the greenhouses grow better.

4) According to this article from NASA, humans’ burning of fossil fuels has caused an increase in the amount of carbon dioxide in the air. But the world did not end. On the contrary, the title of the NASA article is “Carbon Dioxide Fertilization Greening Earth, Study Finds.”

So there we have four different real world examples – all verified by scientists – that show that having higher levels of carbon dioxide causes an increase, not a decrease, in plant life.

Animals eat plants.

And other animals eat the animals that eat plants.

Carbon dioxide is plant food.

Carbon dioxide if the bottom of the food chain.

Therefore, to repeat my hypothesis: Even if we were to do absolutely nothing to reduce our emissions of carbon dioxide in the next 12 years, our release of carbon dioxide will not cause the world to end in 12 years.

One of the great things that we learn from the scientific method is that if an event is based on science, then that event can be repeated. Given the four scientific observations that I have posted above, science tells us that having more carbon dioxide in the air makes things better for life, not worse.

Another great thing about the scientific method is that over time, we can find out if our hypothesis turns out to be true or false.

So all we have to do now is to wait 12 years, and we’ll find out who is right and who is wrong about the world ending in 12 years due to our emissions of carbon dioxide.

Ocasio-Cortez says the world will end in 12 years. She is absolutely right.

January 24, 2019

Apparently all anyone has any strength or enthusiasm for is applying a literalism test on Rep. Alexandria Ocasio-Cortez (D-N.Y.)’s all-too-accurate warnings. She said recently that if we don’t start to address climate change aggressively right now, the world will end in 12 years. I know, let’s feign alarm that she has exaggerated instead of having genuine alarm about the genuine problem she is raising the red flags over.

Here’s another idea. Why don’t we apply the same exactitude of judgment on some other things that have been said about climate change? Here’s a sampler:

“Climate change is a hoax.” “The science is unclear.” “If there were warming, we’d see it.” “If we saw it, we’d do something.” “Maybe it’s cooling.” “It’s too soon to act.” “There’s nothing we can do.” “If this is climate change, I’ll take it!” “It’s arrogant to think humans could change the climate.” “It’s cold today, so climate science is wrong.” “Yes, there’s a problem but hardly a crisis.”

That last position is where the Washington consensus currently resides (President Sir Lies-a-Lot notwithstanding), and it is that position that is dangerously wrong, and what AOC is (correctly) fighting against. The last word on the subject from the Intergovernmental Panel on Climate Change could not have been more dire.

We need to start NOW, to cut carbon emissions aggressively, or by 2030 we may have passed a tipping point beyond which the planet, and yes you people living on it, is in for a world of possibly permanent hurt. So let’s quibble that AOC said the world will end instead of the world as humans and current species have known it and depended on it will end, forever.

Meanwhile, your friendly corporations believe in climate change, all right. They are planning to bleed your last coins into their pockets selling you generators when the climate disasters wipe out your power grid.

Now tell me who is getting this crisis right and in your best interests.

NASA: “Carbon Dioxide Fertilization Greening Earth, Study Finds”

Carbon Dioxide Fertilization Greening Earth, Study Finds

April 26, 2016

From a quarter to half of Earth’s vegetated lands has shown significant greening over the last 35 years largely due to rising levels of atmospheric carbon dioxide, according to a new study published in the journal Nature Climate Change on April 25.

An international team of 32 authors from 24 institutions in eight countries led the effort, which involved using satellite data from NASA’s Moderate Resolution Imaging Spectrometer and the National Oceanic and Atmospheric Administration’s Advanced Very High Resolution Radiometer instruments to help determine the leaf area index, or amount of leaf cover, over the planet’s vegetated regions. The greening represents an increase in leaves on plants and trees equivalent in area to two times the continental United States.

Green leaves use energy from sunlight through photosynthesis to chemically combine carbon dioxide drawn in from the air with water and nutrients tapped from the ground to produce sugars, which are the main source of food, fiber and fuel for life on Earth. Studies have shown that increased concentrations of carbon dioxide increase photosynthesis, spurring plant growth.

However, carbon dioxide fertilization isn’t the only cause of increased plant growth—nitrogen, land cover change and climate change by way of global temperature, precipitation and sunlight changes all contribute to the greening effect. To determine the extent of carbon dioxide’s contribution, researchers ran the data for carbon dioxide and each of the other variables in isolation through several computer models that mimic the plant growth observed in the satellite data.

Results showed that carbon dioxide fertilization explains 70 percent of the greening effect, said co-author Ranga Myneni, a professor in the Department of Earth and Environment at Boston University. “The second most important driver is nitrogen, at 9 percent. So we see what an outsized role CO2 plays in this process.”

About 85 percent of Earth’s ice-free lands is covered by vegetation. The area covered by all the green leaves on Earth is equal to, on average, 32 percent of Earth’s total surface area – oceans, lands and permanent ice sheets combined. The extent of the greening over the past 35 years “has the ability to fundamentally change the cycling of water and carbon in the climate system,” said lead author Zaichun Zhu, a researcher from Peking University, China, who did the first half of this study with Myneni as a visiting scholar at Boston University.

Every year, about half of the 10 billion tons of carbon emitted into the atmosphere from human activities remains temporarily stored, in about equal parts, in the oceans and plants. “While our study did not address the connection between greening and carbon storage in plants, other studies have reported an increasing carbon sink on land since the 1980s, which is entirely consistent with the idea of a greening Earth,” said co-author Shilong Piao of the College of Urban and Environmental Sciences at Peking University.

While rising carbon dioxide concentrations in the air can be beneficial for plants, it is also the chief culprit of climate change. The gas, which traps heat in Earth’s atmosphere, has been increasing since the industrial age due to the burning of oil, gas, coal and wood for energy and is continuing to reach concentrations not seen in at least 500,000 years. The impacts of climate change include global warming, rising sea levels, melting glaciers and sea ice as well as more severe weather events.

The beneficial impacts of carbon dioxide on plants may also be limited, said co-author Dr. Philippe Ciais, associate director of the Laboratory of Climate and Environmental Sciences, Gif-suv-Yvette, France. “Studies have shown that plants acclimatize, or adjust, to rising carbon dioxide concentration and the fertilization effect diminishes over time.”

“While the detection of greening is based on data, the attribution to various drivers is based on models,” said co-author Josep Canadell of the Oceans and Atmosphere Division in the Commonwealth Scientific and Industrial Research Organisation in Canberra, Australia. Canadell added that while the models represent the best possible simulation of Earth system components, they are continually being improved.

Perhaps biological evolution created homo sapiens for the purpose of putting carbon back into the atmosphere

http://news.heartland.org/newspaper-article/2015/03/20/why-i-am-climate-change-skeptic

By Patrick Moore

Editor’s Note: Patrick Moore, Ph.D., has been a leader in international environmentalism for more than 40 years. He cofounded Greenpeace.

Human Emissions Saved Planet

Over the past 150 million years, carbon dioxide had been drawn down steadily (by plants) from about 3,000 parts per million to about 280 parts per million before the Industrial Revolution. If this trend continued, the carbon dioxide level would have become too low to support life on Earth. Human fossil fuel use and clearing land for crops have boosted carbon dioxide from its lowest level in the history of the Earth back to 400 parts per million today.

At 400 parts per million, all our food crops, forests, and natural ecosystems are still on a starvation diet for carbon dioxide. The optimum level of carbon dioxide for plant growth, given enough water and nutrients, is about 1,500 parts per million, nearly four times higher than today. Greenhouse growers inject carbon-dioxide to increase yields. Farms and forests will produce more if carbon-dioxide keeps rising.
