Are Parts of India Becoming Too Hot For Humans? (foxcarolina.com) 268

"Intense heat waves have killed more than 100 people in India this summer and are predicted to worsen in coming years, creating a possible humanitarian crisis as large parts of the country potentially become too hot to be inhabitable," writes CNN.

An anonymous reader quotes their report: Heat waves in India usually take place between March and July and abate once the monsoon rains arrive. But in recent years these hot spells have become more intense, more frequent and longer...

India is among the countries expected to be worst affected by the impacts of climate crisis, according to the Intergovernmental Panel on Climate Change. Experts at the Massachusetts Institute of Technology say that even if the world succeeds in cutting carbon emissions, limiting the predicted rise in average global temperatures, parts of India will become so hot they will test the limits of human survivability...

In June, Delhi hit temperatures of 48 degrees Celsius (118 Fahrenheit), the highest ever recorded in that month. West of the capital, Churu in Rajasthan nearly broke the country's heat record with a high of 50.6 Celsius (123 Fahrenheit)... And forecasters believe it's only going to get worse. "In a nutshell, future heatwaves are likely to engulf in the whole of India," said AK Sahai and Sushmita Joseph, of the Indian Institute of Tropical Meteorology, in Pune in an email.

          Let's look at some facts. China and the USA are the two largest producers of CO2. In 2015 they produced 9040.74 and 4997.50 MT (million metric tons) respectively. India came third at 2066.01.

          In terms of per capita production of CO2, the United States easily captures 1st place with 15.51 metric tons per person. Second and third are Russia (10.19) and China (6.59). India is way down the list after many other countries, at 1.58.

                      If we are to be looking at this from an objective perspective, we should be measuring per-country CO2 emissions reported to said country geographical surface. While indeed more people would generate more CO2 emissions, what matters for global warming is how much CO2 is pumped out divided to the surface of the world.
                      A cluster of 5 people located on a large island, each of them having a huge carbon footprint, would yield an insignificant

                    • That makes no sense. Emissions per geographic area is meaningless - it is the overall total amount of CO2 which is important for the Earth's climate. What would emissions per square km even tell you other than perhaps how densely populated the area is...

                  • It does seem quite common for people on here to play games with statistics to assign blame but of course it's very difficult to tell the full story with a handful of figures. There are a lot of questions to ask if you want to see to what extent you or your country is part of the problem, some more obvious than others. One needs to at least consider power generation, power efficiency, population growth, contribution to tech, contribution to PR, imports with high carbon footprint, choosing correct measures
                • by Phaid ( 938 )

                  Per capita CO2 numbers mean nothing. Most of China is not industrialized, so it's not really surprising that their per capita output is lower. It's more interesting to look at CO2 per unit of GDP, which reflects how carbon efficient a country's industries are.

                  • GDP is not interesting. Financial actions e.g. contribute to the GDP but don't really produce CO2.
                    GDP is not really comparable from country to country because of currency differences. If I a Thai dish in Germany it costs perhaps EUR7.00 about $8.00 and in Thailand the exact same dish costs me $1.10 or something (50TBH). So for the same thing the GDP in Germany is 8 times higher ... obviously nonsense.

                    A typical citizen, living in a to big house, driving a to big car, to lazy to cool only the room s/he is in, to lazy to switch the AC off when s/he is at work, or to lazy to have a timer starting the AC an hour before he is home, has nothing to do with the GDP, except as consumer of energy and buying the car ... but he could by a high consuming but cheap car, too.

                    There is another metric, but I forgot how it is exactly named in english: CO2 per amount of produced goods.

              Your table was only for CO2 from fuel combustion. If we consider all green house gas emissions (at CO2) equivalence then we get Canada and Australia as the worst industrialized countries. https://en.wikipedia.org/wiki/... [wikipedia.org]
              It also gets worse for Canada. We under report our numbers. Everyone does a little but we do a lot. Everyone under reports their oil and gas a bit but our tar sands are far dirtier and fly over air measurement reveal we are under reporting by a fair margin. Second, Canada argued countries could optionally subtract carbon natural carbon sinks if they wanted. Unfortunately we have so mismanaged our mono culture replanting of forests that our forests are net green house gas emitters.

              So stop blaming India or China when Australians, Canadians and Americans are far far worse.

              For one it shows there is a much higher potential for china to pollute even more, if it comes to the SAME living standard and production standard than the USA. For two it still shows per person a vast amount of energy being used, and one has to question next : is the amount of product and service produced per person , proportionate to the amount of energy (or by proxy CO2) emitted : an indicative of wasted energy on other level of the society.

And finally it reeks of "i got mine but now that you are growing and have more people to support I'll just point the finger at you and put more responsibility onto you the country with more people and pretend you need to do at least as much as me the waster".

                The former is not news. The latter is misleading. Only a percentage of the pollution produced by a country is produced by its people living their lives. Some other percentage is produced by economic activity, those people at their jobs. And that economic activity is a partnership between the producer and consumer of a product or service. People blame residents of the USA (and rightly so) for a large share of China's pollution, as the US is China's primary trading partner. We have funded their pollution. But the USA is also one of the world's largest manufacturing nations, and one of its largest exporters of goods. What percentage of our pollution is (by the same logic) the responsibility of persons living in other nations, buying our products?

                The issue of shared responsibility is a secondary one, however. One real question is, how much pollution does the average American actually produce? According to the EPA, approximately 50% of America's pollution comes from industrial sources. Another question might be how much pollution is produced by the median American. Virtually all the wealth is in a few hands. And one final question I've got is how much pollution is being produced by the median American because they can't afford to avoid it? I'd love to have an EV instead of a diesel, but I can't afford one — especially one with enough range to get around the part of California I live in.

            Okay fine. America can stop manufacturing stuff for the entire world which will bring our carbon footprint per capita way below any other industrialized nation.

            But how will you stop someone else from manufacturing what the world needs? Someone else absolutely will manufacture what the world wants and they won't have the same laws concerning pollution and how they treat their workers.

          China spends more than the US does investing in sustainable energy and lower emissions technologies.

          Part of it is because they realize having air quality so poor is a bad thing. Part of is is the realization that relying on energy you don't control (e.g. imported petroleum) is a major economic and political liability. Part of it is that renewable energy is just less expensive than many of the alternatives.

          In any case, China sees the writing on the wall and is working to better their situation.

      There are other explanations for this result as well. The first is that as India has industrialized, people are living longer and there are more old people as a percentage of total population to die in a heat wave. Previously something else killed them first and as India does more to reduce deaths from other leading causes, something else eventually has to kill them. Add on that the country's population has been growing significantly over that span along with better recording and reporting of these incidents and there's little wonder that we're hearing this.
