Is climate change man made or Natural?

Not interested in watching an hour of poppycock which has gotten this criticism:

This

Obviously, modern human activity affects certain things like the creation of 'urban heat islands' but that is where the significant impacts stop.

Everything else is in nature's hands and rightly so. Only the arrogant and woefully unintelligent believe otherwise.

You have a point in that we've already locked in a certain amount of warming (probably more than 1.5 C IMO). Have to call bullshit on everything else though, being less fucked over is always preferable to being more fucked over. 

In 1987, Biden Predicted “A Catastrophe Of Biblical Proportions For The Entire World” From Global Warming “In The Next Few Years”

In 1987, then-U.S. Senator Joe Biden Said, “Global warming, should it occur in accord with the direst predictions, would be a catastrophe of biblical proportions for the entire world” “‘Global warming, should it occur in accord with the direst predictions, would be a catastrophe of biblical proportions for the entire world,’ he said in a Senate floor speech. ‘The human activities that could bring it about — the inefficient burning of fossil fuels…the destruction of tropical forests — are occurring right now. And unless these activities are changed in the next few years…a disastrous and irreversible warming could become inevitable.’ He pushed legislation that would form a task force that would be mandated to study global warming and come up with recommendations for further action.” (Matt Viser, John Wagner, And David Weigel, “Climate Change Tests Joe Biden As He Confronts A Major Question For Democrats: Is Any Compromise Too Much?” The Washington Post, 5/14/19)

In 1989, A UN Study Predicted That By 2000 Entire Nations Would Be Wiped Off The Face Of The Earth From Global Warming

In 1989, a United Nations study predicted that by 2000 entire nations would be wiped off the face of the earth from global warming. “A senior U.N. environmental official says entire nations could be wiped off the face of the Earth by rising sea levels if the global warming trend is not reversed by the year 2000. Coastal flooding and crop failures would create an exodus of ‘eco-refugees,’ threatening political chaos, said Noel Brown, director of the New York office of the U.N. Environment Program, or UNEP.” (Peter James Spielmann, “U.N. Predicts Disaster if Global Warming Not Checked,” Associated Press, 6/29/89)

They said the government had a 10-year window before the greenhouse effect went beyond human control and that entire nations would be wiped from the map and millions of people displaced. “He said governments have a 10-year window of opportunity to solve the greenhouse effect before it goes beyond human control. As the warming melts polar icecaps, ocean levels will rise by up to three feet, enough to cover the Maldives and other flat island nations, Brown told The Associated Press in an interview on Wednesday. Coastal regions will be inundated; one-sixth of Bangladesh could be flooded, displacing a fourth of its 90 million people. A fifth of Egypt’s arable land in the Nile Delta would be flooded, cutting off its food supply, according to a joint UNEP and U.S. Environmental Protection Agency study. ‘Ecological refugees will become a major concern, and what’s worse is you may find that people can move to drier ground, but the soils and the natural resources may not support life. Africa doesn’t have to worry about land, but would you want to live in the Sahara?’ he said. UNEP estimates it would cost the United States at least $100 billion to protect its east coast alone.Shifting climate patterns would bring back 1930s Dust Bowl conditions to Canadian and U.S. wheatlands, while the Soviet Union could reap bumper crops if it adapts its agriculture in time, according to a study by UNEP and the International Institute for Applied Systems Analysis.” (Peter James Spielmann, “U.N.

In 1995, A UN Study Predicted That Rising Sea Levels Would Cause Most Of The Beaches On The East Coast Of The United States To Disappear By 2020

In 1995, a United Nations study predicted that rising sea levels would cause most of the beaches on the East Coast of the United States to disappear by 2020. “According to draft sections of the new forecast, some of the predicted effects of climate change may now be emerging for the first time or with increasing clarity. The possible early effects include these: *A continuing rise in average global sea level, which is likely to amount to more than a foot and a half by the year 2100. This, say the scientists, would inundate parts of many heavily populated river deltas and the cities on them, making them uninhabitable, and would destroy many beaches around the world. At the most likely rate of rise, some experts say, most of the beaches on the East Coast of the United States would be gone in 25 years. They are already disappearing at an average of 2 to 3 feet a year. *An increase in extremes of temperature, dryness and precipitation in some regions. A United States Government study conducted by one of the panel’s scientists has shown that these extremes are increasing in America. There is a 90 to 95 percent chance, the study concluded, that climate change caused by the emission of greenhouse gases like carbon dioxide is responsible. The intergovernmental panel forecasts an increase in droughts like the current one in the Northeastern United States, heat waves like the one in Chicago this summer, and more fires and floods in some regions.*A “striking” retreat of mountain glaciers around the world, accompanied in the Northern Hemisphere by a shrinking snow cover in winter. In some semi-arid regions, the panel says, runoff from melting glaciers may increase water resources. But in most places, rivers and streams could be diminished in the summer.”” (William K. Stevens, “Scientists Say Earth’s Warming Could Set Off Wide Disruptions,” The New York Times, 9/18/95)

In 2000, British Climate Scientists Predicted That Within A Few Years They Would No Longer Experience Snow And “Snow Will Probably Cause Chaos In 20 Years Time”

In 2000, British climate scientists predicted that within a few years they would no longer experience snow, “Children just aren’t going to know what snow is.” “Global warming, the heating of the atmosphere by increased amounts of industrial gases, is now accepted as a reality by the international community. Average temperatures in Britain were nearly 0.6°C higher in the Nineties than in 1960-90, and it is estimated that they will increase by 0.2C every decade over the coming century. Eight of the 10 hottest years on record occurred in the Nineties. However, the warming is so far manifesting itself more in winters which are less cold than in much hotter summers. According to Dr. David Viner, a senior research scientist at the climatic research unit (CRU) of the University of East Anglia, within a few years winter snowfall will become ‘a very rare and exciting even.’ ‘Children just aren’t going to know what snow is,’ he said.” (Charles Onians, “Snowfalls are now just a thing of the past” Associated Press, 6/29/89)

Dr. David Viner, a senior research scientist at the climatic research unit (CRU) of the University of East Anglia: “We’re really going to get caught out. Snow will probably cause chaos in 20 years time.” “David Parker, at the Hadley Centre for Climate Prediction and Research in Berkshire, says ultimately, British children could have only virtual experience of snow. Via the internet, they might wonder at polar scenes – or eventually ‘feel’ virtual cold. Heavy snow will return occasionally, says Dr. Viner, but when it does we will be unprepared. ‘We’re really going to get caught out. Snow will probably cause chaos in 20 years time,’ he said.” (Charles Onians, “Snowfalls are now just a thing of the past” Associated Press, 6/29/89)

In 2009, Al Gore Claimed New Research Showed The Arctic Could Be Ice-Free Within Five Years

In 2009 at a Copenhagen climate change summit, Al Gore claimed new research showed the Arctic could be ice-free within five years. “Mr. Gore, speaking at the Copenhagen climate change summit, stated the latest research showed that the Arctic could be completely ice-free in five years. In his speech, Mr. Gore told the conference: ‘These figures are fresh. Some of the models suggest to Dr. [Wieslav] Maslowski that there is a 75 per cent chance that the entire north polar ice cap, during the summer months, could be completely ice-free within five to seven years.’” (Frank James, “Al Gore Slips On Artic Ice; Misstates Scientist’s Forecast,” NPR, 12/15/09)
The scientist cited for this claim said Gore got it wrong, “It’s unclear to me how this figure was arrived at.” “However, the climatologist whose work Mr. Gore was relying upon dropped the former Vice-President in the water with an icy blast. ‘It’s unclear to me how this figure was arrived at,’ Dr. Maslowski said. ‘I would never try to estimate likelihood at anything as exact as this.’” (Frank James, “Al Gore Slips On Artic Ice; Misstates Scientist’s Forecast,” NPR, 12/15/09)

In 2014, A French Official Appearing With Then-Secretary Of State John Kerry Said That There Was Only “500 Days To Avoid Climate Chaos”

In 2014, in a joint appearance with then-Secretary of State John Kerry, the French Foreign Minister Laurent Fabius said, “We have 500 days to avoid climate chaos.” “Well, I’m very happy to be with John. There is no week without a phone call or a visit between John and myself, and we have on the agenda many items, many issues – Iran, because negotiations are resuming today; the question of Syria, and we shall meet next Thursday in London together; Ukraine as well; and very important issues, issue of climate change, climate chaos. And we have – as I said, we have 500 days to avoid climate chaos. And I know that President Obama and John Kerry himself are committed on this subject and I’m sure that with them, with a lot of other friends, we shall be able to reach success on this very important matter.” (Remarks With French Foreign Minister Laurent Fabius Before their Meeting, U.S. Department of State, 5/13/14)

In 2019, Rep. Alexandria Ocasio-Cortez And Greta Thunberg Predicted The World Will End By About 2030

In January 2019, Rep. Alexandria Ocasio-Cortez predicted “the world is going to end in 12 years if we don’t address climate change.” “I think that the part of it that is generational is that millennials. And gen z and all those who come after us are looking up and we’re like the world is going to end in 12 years if we don’t address climate change and you’re biggest issue is how are we going to pay for it. And, like this is the war. This is our World War 2.” (Rep. Alexandria Ocasio-Cortez, Speaking at #MLKNow​ 2019 by Blackout for Human Rights, 1/21/19, Minute 53:25 to 53:55)

In her 2019 book No One Is Too Small to Make a Difference, Greta Thunberg claims, “Around 2030 we will be in a position to set off an irreversible chain reaction beyond human control that will lead to the end of our civilization as we know it.” “Says Thunberg in her new book, ‘Around 2030 we will be in a position to set off an irreversible chain reaction beyond human control that will lead to the end of our civilization as we know it.’” (Greta Thunberg, “No One Is Too Small to Make a Difference,” 6/6/19; Michael Shellenberger, “Why Apocalyptic Claims About Climate Change Are Wrong,” Forbes, 11/25/19)

During The 2020 Campaign, Biden’s Energy Plan Called For A “100% Clean Energy Economy” By 2050 For “Our Children And Grandchildren”

Biden’s 2020 campaign climate plan called for a “100% clean energy economy” by 2050 “not just for all of us today, but for our children and grandchildren, so their tomorrow is healthier, safer, and more just.” “Getting to a 100% clean energy economy is not only an obligation, it’s an opportunity. We should fully adopt a clean energy future, not just for all of us today, but for our children and grandchildren, so their tomorrow is healthier, safer, and more just. As president, Biden will lead the world to address the climate emergency and lead through the power of example, by ensuring the U.S. achieves a 100% clean energy economy and net-zero emissions no later than 2050.” (“Climate,” Biden For President, Accessed 1/24/20)

In August 2019, while campaigning, Biden called for “complete total elimination of fossil fuels by the year 2050.” BIDEN: “We are in a position to be able to, in fact, remain energy independent by moving to complete total elimination of fossil fuels by the year 2050 starting now.” (Biden Speaking At Campaign Townhall, 8/9/19, Minute 2:15-2:31)

This isn't as much an issue of climate as it is of soils for growing crops. Most of today's taiga has shitty soils due to having been scoured by ice sheets relatively recently, lack of deciduous trees and grazing animals to fertilize the soil, and being really cold for most of the year. 

Mix of both. Climate change is natural, but humans do have varying effects on some contemporary changes.
