Climate change is coming for everyone, but it鈥檚 coming much faster for some of us. People living in low-income communities are by storms and floods exacerbated by climate change. Low-lying portions of island nations like the Maldives are projected to be uninhabitable by , and researchers worry that the combination of high temperatures and humidity levels in South Asia and the Persian Gulf could make those regions .

Qatar, in particular, has recently been the subject of interest in Western media. A recent Washington Post piece that Qataris have taken to air conditioning outside spaces, like restaurant patios and sports stadiums built for the 2022 World Cup. Air conditioning, the author wrote, is a 鈥渧icious cycle鈥濃攖he energy required to run AC outdoors requires emissions, which in turn feeds climate change. picked up the news, calling it 鈥渆nvironmental lunacy.鈥 One linking to the piece says that by running air conditioning, Qataris are 鈥渕aking the heat worse as they try to cool off.鈥

This is a convenient narrative for Westerners. It fits into the existing framework of North American discourse about climate change (hot places will get hotter!), and readers in cooler climes get to feel concerned, but in a self-righteous way鈥攚ow, look how bad things are getting all the way over there, and how those other people are making it worse for themselves!

Individual decisions do, in the aggregate, contribute to change. But telling people in 120-degree weather to avoid outdoor air conditioning obscures the real emissions culprits.

Outdoor air conditioning is nothing new. North Americans have used it for years in desert cities like Phoenix to make sitting outside bearable. As far back as 2008, Gizmodo鈥檚 Adam Frucci mocked outdoor air conditioners as 鈥,鈥 and in 2011, Phoenix restaurants began advertising . A recommends outdoor air conditioning for Arizona homeowners who 鈥渓ove their outdoor lifestyle鈥 and want a solution for when 鈥渋t gets a little too hot to sit outside on the covered patio.鈥 Elsewhere in North America, patio sitters have the opposite problem: It鈥檚 too cold. Patio heaters, open fires, and gas- or electric-powered fire pits make sitting outdoors cozier.

While there are no direct comparisons of energy use between outdoor air conditioning and outdoor heating, both are inefficient. Valerie Thomas, a professor at Georgia Tech who studies energy and sustainable infrastructure, says calculating efficiency depends on the specific technology used as well as how often and for how long it鈥檚 used. A small patio heating system operates at about 1,000 watts and costs about $140, while larger units are 1,500 watts and cost around $200, says Thomas. She didn鈥檛 look into electric outdoor air conditioners specifically but says that most common patio-cooling devices, like swamp coolers or fans, use between 200 and 250 watts. Based on that, Thomas says, 鈥渧ery, very approximately one might conclude that heating is somewhat more energy intense than cooling.鈥 Yes, swamp coolers and fans aren鈥檛 the same as AC, but it appears also use around 1,500 watts too. Yet amid discussions of climate change impacts in the U.S., I haven鈥檛 seen any hand-wringing over how Arizonans鈥 use of air conditioning or Californians鈥 use of patio heaters is 鈥渕aking it worse for themselves.鈥

There鈥檚 plenty of discussion about how wasteful indoor air conditioning can be; Americans, in particular, , and the nation鈥檚 bad habits around cooling account for more emissions than . There鈥檚 even evidence that Arizonans鈥 air conditioning habits are making it worse for them; a 2014 study found that air conditioners could by 2 degrees Fahrenheit. But in some cases, 蚕补迟补谤鈥檚 outdoor air conditioning might even be more efficient than traditional indoor air conditioning. Standard heating, ventilating, and air conditioning systems attempt to cool air in an enclosed space; that can be in enormous sports arenas like the Dallas Cowboys鈥 AT&T Stadium, which draws more energy than some midsize cities. Alternatively, the methods used in 蚕补迟补谤鈥檚 stadium designs focus on cooling the individual. The stadium cooling system鈥檚 designer that his invention uses just one-fifth the energy typically used to heat an airport atrium of around the same size, though there are no independent verifications of that calculation.

But let鈥檚 assume these outdoor cooling methods are woefully inefficient. Even then, how much Qataris are actually contributing to this 鈥渧icious cycle鈥 of emissions is an open question. 鈥淨atar emits a lot of greenhouse gases,鈥 writes Post reporter Steven Mufson, noting that the country has the highest per capita emissions rate. 鈥湽悠 60 percent of the country鈥檚 electricity is used for cooling. By contrast, air conditioning accounts for barely 15 percent of U.S. electricity demand and less than 10 percent of China鈥檚 or India鈥檚.鈥 Comparing 蚕补迟补谤鈥檚 emissions or energy use to that of the U.S., China, or India implies that these countries might be, well, comparable鈥攂ut they are not.

If we鈥檙e concerned about who鈥檚 鈥渕aking it worse鈥 for Qataris, it would be shortsighted to ignore the West鈥檚 historically high emissions.

Qatar is about the size of Connecticut and is home to about 2.6 million people. (Connecticut鈥檚 population, by the way, is around 3.5 million.) It鈥檚 responsible for less than 1 percent of global emissions, says Eri Saikawa, an associate professor at Emory University who studies emissions. 鈥湶喜钩俨拱檚 emissions as a whole are very small,鈥 she told me. And the energy devoted to cooling makes sense too, considering the weather. 鈥淚t seems a bit like an unfair comparison to me,鈥 she says. Consider this from Climate Watch for a visual representation of how the United States鈥 total emissions have dwarfed 蚕补迟补谤鈥檚 for 25 years; the default settings for the y-axis make it look like 蚕补迟补谤鈥檚 emissions are essentially zero compared with the roughly 6.0 gigatons the U.S. emits each year. Just comparing the most recent figures, from 2014, Qatar emitted 88 megatons, while the U.S. emitted 6.3 gigatons (equivalent to 6,300 megatons)鈥敳喜钩俨拱檚 emissions were just 0.01 percent of the United States鈥. It鈥檚 true that, as Mufson writes, Qatar has the highest per capita emissions rate. According to data from , the average Qatari produces 2.74 times the emissions of an average American and nearly 5.8 times that of an average Chinese citizen. But that鈥檚 not all, or even mostly, because of cooling costs鈥攖he large amounts of liquefied natural gas the country exports count as 蚕补迟补谤鈥檚 emissions footprint, rather than that of the countries to which it exports, like .

If we鈥檙e concerned about who鈥檚 鈥渕aking it worse鈥 for Qataris, it would be shortsighted to ignore the West鈥檚 historically high emissions. The six countries with top emissions in 1850鈥攖he U.S., the EU, China, Germany, India, and Russia鈥攁re still top emitters. Between 1990 and 2014, the U.S. and Canada topped the list of the world鈥檚 . 鈥淭he U.S. has been emitting so much that they have some responsibility to bear for historical emissions,鈥 says Saikawa. The cumulative contributions of these high-emitting countries are many tens of thousands of times what Qataris are using annually to stay cool. Even if Qataris completely stopped using air conditioning, it would take a long time for the change to make an impact, says Saikawa. 鈥淚f they are going to stop for a hundred years, of course, that could potentially count, but in the current grand scheme of things, there is so much more we can do,鈥 like reducing coal-based emissions and more effectively using solar energy.

The Qataris have considered this. In the Post piece, the author interviews Abdulla al-Mannai, director of the Qatar Meteorology Department.

鈥淚 often get asked: 鈥楥an we reverse whatever is happening in the climate?鈥 鈥 Mannai said in an email. 鈥淚 ask: Can you turn off air conditioning and refrigeration and stop using cars? Nobody will say yes.鈥

鈥淣obody鈥 includes all of us, not just Qataris. Christopher Groves, a research fellow at Cardiff University, has studied energy justice and the role of identity and culture in people鈥檚 energy use. he wrote in collaboration with other Cardiff researchers features an interview with a woman named Lucy from Wales who uses the opposite of the Qataris鈥 kind of outdoor climate control: a patio heater. Lucy had moved from the city into the country and said she knew the heater was wasteful, but she wanted her friends from the city to come visit and feel at home. 鈥淲ays of using energy that might otherwise be seen as wasteful are鈥攊n Lucy鈥檚 case but also in the Qatari context鈥攕een as justifiable because of the ways they symbolise material abundance and luxury,鈥 says Groves. 鈥淭here are situations where waste is seen almost as morally necessary to support a valued way of life.鈥

Groves asks if it鈥檚 fair to ask people to give up these values鈥攁nd, more importantly, what might convince people to change their behavior. Lucy, for instance, mentioned that her neighbors also used wasteful means of heat production, like burning wood in open fires, and that those practices were part of the community. 鈥淢otivation for giving that up has to come, ideally, from within the community to which someone has essential attachments,鈥 says Groves. 鈥淪imply demanding, from an external vantage point, that things have to change generally doesn鈥檛 work.鈥 Giving up these pieces of identity 鈥渃an be psychologically difficult.鈥

There鈥檚 been plenty of ink spilled suggesting that people forgo wasteful outdoor AC or shaming people for flying, eating meat, using plastic, buying new clothes, and using or any number of inefficient but ubiquitous technologies out there, but the collective impact is still a drop in the bucket and, as Groves notes, unlikely to work without large-scale buy-in. A found that more than 70 percent of the world鈥檚 emissions since 1988 were traceable to just 100 companies. Comparatively, whether someone runs an outdoor air conditioning unit for an hour during a restaurant meal seems like a drop in a vast ocean of emissions.

What you can do: vote, organize, educate, and, in whatever way you can, create dialogue around like moving away from coal-based power and incentivizing more sustainable infrastructure investments. That鈥檚 not to let you off the hook for examining your own energy consumption. But policing others鈥 isn鈥檛 going to get us very far, both from the perspective of generating meaningful behavioral change or significant emissions reductions.
