Concentration of people in the cities also increases their vulnerability to climate change disruption.

城市人口集中，也会增加他们面临气候变化影响的脆弱性。

As the level of concentration increases again, expect more money - not to mention heat - to be generated in the biggest dealing rooms.

随着市场集中度再次提高，预计一些规模最大的交易场所将产生更多的资金——更不用说热情。

As human activity increases the concentration of these gases in the atmosphere far beyond their natural levels, much more heat is trapped.

随着人类活动增加，温室气体在大气层中的浓度超过了自然状态，过多热量被保存。

So if you are going to release 7 to 8 billion metric tons a year into the atmosphere, predictably that increases carbon concentration in our atmosphere.

FORBES: A Call to Arms on Climate Change

It is thought too that as the atmospheric CO2 concentration increases, as it must with the continued burning of fossil fuels, the kinetic energy generation from the atmosphere will decrease thus further diminishing the amount of energy that may be sensibly extracted by wind-turbines on the very large scale.

In the northern hemisphere, every winter the concentration of carbon dioxide increases and every summer it decreases.
