Anonymous asked: I am a man-caused-Climate Change (Global Warming) skeptic. Where should I start looking for evidence?
Thanks for the question. Skepticism is the basis of science, so I somewhat* respect your point of view.
Note: I’m an adaptation specialist and I manage parts of USAID’s climate adaptation program in over 25 countries. This means I help governments around the world with policies that deal with inevitable impacts from climate change. Basically, I help with natural disaster planning using a bit of climate science, city planning, and environmental law. So, if a city is going to flood, I help a government plan to prevent the flood. If a country’s farming economy is going crash due to drought, I help the government shape a response to prevent crop losses. See what I do, here. Thus, I do not work on carbon or energy policy. I am not an activist. I do not advocate for emissions policies. I’m about as interested in “preventing climate change” as I am interested in becoming the next Dali Lama. That said, this is a very rare instance where I answer a question about carbon, GHGs, and energy. Ok, on to anon’s nice question:
Without these gases, the earth would be like the moon - a dead rock that’s freezing and boiling at the same time: +253F (+123C) during the day; -387F (-233C) at night.
There is no disputing this (deniers [unwittingly] admit this when they make arguments about cycles). When there are more gases in the atmosphere, more of the sun’s radiation is held within the atmosphere, creating a warming effect (and very strange changes in weather events).
In sum, your starting point is: Why is the earth warm? It’s warm due to GHGs in the atmosphere. And humans are adding a never before seen amount of carbon into the atmosphere, which in turn will wreak unbelievable havoc. Deniers bear the rather obscene burden of showing that GHGs do not keep the earth warm, and that increases in carbon do not influence climate.
I hope those links above help.
All the best,
*A legitimate skeptic applies critical thinking to systematically pick apart arguments. Skeptics do this by analyzing evidence. No one disagrees that GHGs cause warming (even all oil companies on earth admit this, and are searching for solutions to lower GHG emissions). The burden is on you and other deniers to show that greenhouse gases do not influence the earth’s atmosphere. Frankly, in my opinion, this is a rather boring subject. The more interesting subject is that deniers actually do not comprehend their own arguments. In fact, they’re really arguing against *the solutions* to reducing or preventing climate change, which are to raise the costs of fuels and not pay for environmental harm. This gets into societal ethics, personal responsibility, and market capitalism, which are far more (well, marginally) interesting topics.
It’s been more damaging than the right-wing denialism in terms of how much ground we’ve lost. Because it has steered us in directions that have yielded very poor results.
I think if we look at the track record of Kyoto, of the UN Clean Development Mechanism, the European Union’s emissions trading scheme – we now have close to a decade that we can measure these schemes against, and it’s disastrous.
Not only are emissions up, but you have no end of scams to point to, which gives fodder to the right. The right took on cap-and-trade by saying it’s going to bankrupt us, it’s handouts to corporations, and, by the way, it’s not going to work. And they were right on all counts. Not in the bankrupting part, but they were right that this was a massive corporate giveaway, and they were right that it wasn’t going to bring us anywhere near what scientists were saying we needed to do lower emissions.
So I think it’s a really important question why the green groups have been so unwilling to follow science to its logical conclusions.
Professor tracks donations to climate denial politicians. Finds Exxon and Koch Brothers and others are exploiting the system brilliantly.
In the end, Brulle concluded public records identify only a fraction of the hundreds of millions of dollars supporting climate denial efforts. Some 75 percent of the income of those organizations, he said, comes via unidentifiable sources.
And for Brulle, that’s a matter of democracy. “Without a free flow of accurate information, democratic politics and government accountability become impossible,” he said. “Money amplifies certain voices above others and, in effect, gives them a megaphone in the public square.”
Powerful funders, he added, are supporting the campaign to deny scientific findings about global warming and raise doubts about the “roots and remedies” of a threat on which the science is clear.
"At the very least, American voters deserve to know who is behind these efforts."
Trigger warning: NYTimes goofily portrays Bill Nye the science guy as an anomaly. Science reporting still has a lonnnng way to go…
William Sanford Nye, better known as Bill Nye the Science Guy, has gone from TV host to fierce defender of scientific issues that have been polemicized for religious, political and even economic reasons.
This page examines the science and common arguments of global warming skepticism. Common objections like ‘global warming is caused by the sun’, ‘temperature has changed naturally in the past’ or ‘other planets are warming too’ are examined to see what the science really says.
About six in ten Americans (58%) say “global warming is affecting weather in the United States.”
Many Americans believe global warming made recent extreme weather and climatic events “more severe,” specifically: 2012 as the warmest year on record in the United States (50%); the ongoing drought in the Midwest and the Great Plains (49%); Superstorm Sandy (46%); and Superstorm Nemo (42%).
About two out of three Americans say weather in the U.S. has been worse over the past several years, up 12 percentage points since Spring 2012. By contrast, fewer Americans say weather has been getting better over the past several years - only one in ten (11%), down 16 points compared to a year ago.
Overall, 85 percent of Americans report that they experienced one or more types of extreme weather in the past year, most often citing extreme high winds (60%) or an extreme heat wave (51%).
Of those Americans who experienced extreme weather events in the past year, many say they were significantly harmed. Moreover, the number who have been harmed appears to be growing (up 5 percentage points since Fall 2012 and 4 points since Spring 2012).
Over half of Americans (54%) believe it is “very” or “somewhat likely” that extreme weather will cause a natural disaster in their community in the coming year.
Americans who experienced an extreme weather event are most likely to have communicated about it person-to-person - either in person (89%) or on the phone (84%).

The campaign group formed to support Barack Obama's political agenda has launched an initiative to shame members of Congress who deny the science behind climate change.
In an email to supporters on Thursday, Organizing for Action said it was time to call out members of Congress who deny the existence of climate change, saying they had blocked efforts to avoid its most catastrophic consequences.
The email linked to a video mocking Republicans who reject the science on climate change. “Right now, way too many lawmakers in Washington flat-out refuse to face the facts when it comes to climate change,” Jon Carson, executive director of Organizing for Action wrote in the email. “We’re never going to make real progress on this issue unless members of Congress get serious.”
The video mainly features Republican members of the House of Representatives who are notorious for denying the existence of climate change, or positing bizarre notions about its causes.
However, it also includes some national figures such as the Florida senator Marc Rubio and House speaker John Boehner, whose views on climate are not that broadly known. There are no Democrats in the video.
Thursday’s report by dozens of scientists from five different federal agencies looked into why forecasters didn’t see the drought coming. The researchers concluded that it was so unusual and unpredictable that it couldn’t have been forecast.
"This is one of those events that comes along once every couple hundreds of years," said lead author Martin Hoerling, a research meteorologist at the National Oceanic and Atmospheric Administration. "Climate change was not a significant part, if any, of the event."
Every major oil company has a climate change division. Most have active climate change plans aimed at reducing emissions, managing environmental risks, and experimenting with alternatives to reduce climate impacts. Importantly, these are voluntary efforts.They chose to manage and discuss climate risk.
