# Why is the temperature *still* rising?

2015 is the hottest year on record, and the average temperature continues to rise.

I don't understand why this continues, as (over the past twenty years) so much work was put into reducing Global Warming over the past 40 years, yet not only does the temperature not fall, it continues to rise more than it did between 1870-1960.

I don't understand something. The amount of industry went through the roof (literally) between 1870 to 1960, and no one cared about the environment

Now that we do care about it, and (at least somewhat) legislate cleaner cars, factories, etc, I would expect the temperature to even out, yet it doesn't

Why not?

I don't have time to write a full answer, but a major part of the answer lies in your assumption that ‘so much work was put into reducing Global Warming over the past 40 years’. This is not really the case. Here's a graph of global fossil CO2 emissions since 1900. As you can see, there hasn't been any significant decrease in the rate of CO2 emissions; it's actually increased since 2000. Atmospheric CO2 concentrations tell a similar story. – Pont Jan 20 at 22:29
If you think that "so much work" has been done so far in trying to reduce temperature rise & nothing has much has resulted from this, just think how much more work needs to be done to reduce or stop increases in temperature. – Fred Jan 20 at 23:36
Climate talkfests should never be regarded a "hard work". At best they are events for information interchange. For temperatures to reduce actual work needs to be done in stopping the rise of green house gases in the atmosphere. – Fred Jan 20 at 23:47
Also, the temperature response to an increase in CO2 is far from instantaneous. Think of turning on the burner under your teakettle: the water doesn't boil instantly, does it? CO2 added this year just turns up the burner a bit: it traps solar radiation forever, so the temperature continues to increase until a new equilibrium is reached, perhaps decades or even centuries from now. – jamesqf Jan 21 at 6:49
It's not so much work that has been put into it, It's so much talk! – Hanky Panky Jan 22 at 10:02

"So much work"? Actually, compared to the global rate of greenhouse gas emissions, it's a case of "so little work"! From a scientific perspective the 'economists' solution' of carbon trading was always unlikely to achieve the required carbon cuts, as has been verified by their ineffectiveness over the last decade or so. As farrenthorpe points out, the rate of increase of CO2 is largely population-driven, and hence there is still an inexorable rise in mean atmospheric CO2. The acid test of human efforts to limit global warming is whether the Hawaiian CO2 monitoring graph is flattening off:

It clearly isn't going to flatten anytime soon. In fact, if anything, it is getting steeper. So all the hot air from 'Paris', and previous talkfests, is evidently too little, too late. Realistically, limiting the average temperature rise to less than 2 °C, is now effectively unattainable. We have yet to see what 'all this work' can achieve. So far, almost nothing.

It's also important to realize that even if the graph flattens out, our atmosphere is in a state where the temperature will continue to rise. We need to reduce CO2 levels in order to get to point where the temperature will stabilize, and reduce them further to start cooling. – Randy Orrison Jan 21 at 16:02
"So far, almost nothing." Honestly, it's hard to say that for sure. To gauge the effectiveness of efforts so far, you must compare against what the outcome would have been had those efforts not been taken. The last ~20 years have seen massive economic growth in the Asia Pacific region, as well as parts of the Middle East. Even if the entire West stopped carbon emissions altogether, the industrialization of India, China, etc. would have almost certainly more than made up the difference in total global carbon emissions. – reirab Jan 21 at 16:14
Isn't Mauna Loa an active volcano? – Barry Carter Jan 27 at 18:21

Your premises are flawed due to the lack of two critical details:

1. Population rise; the sheer number of people on the planet that are consuming resources has risen to 7 billion people.
2. Standard of Living; a greater percentage of people in the world live a "Western" style, which consumes more goods per capita.

You should study something like the Global Carbon Project to gain a greater perspective on carbon and climate.
