Future Trends Flashcards
What trend is projected for greenhouse gas emissions in all projections?
Greenhouse gas emissions are projected to rise in all projections.
Describe the trend in emissions between 2008 and 2014.
After 2008, emissions fell to 1% by 2012-13 down from 4%, then fell to 0.5% in 2014. Despite this, total carbon emissions still reached a record high.
How much did energy consumption grow between 2008 and 2014, and what proportion of the increase in electricity production in 2015 was accounted for by renewables?
Energy consumption grew by 2% between 2008-2014. However, renewables made up two-thirds of the increase in electricity production in 2015.
What factor may contribute to an increase of potentially a billion consumers by 2050?
Increasing affluence may lead to a potential extra billion consumers by 2050.
Which three countries were the largest CO2 emitters by 2014?
By 2014, the three largest CO2 emitters were China, the USA, and India.
How did China’s position as a CO2 emitter change in relation to the USA after 2000?
In 2000, China overtook the USA as the largest CO2 emitter due to global shifts in manufacturing projections, rapid urbanisation, and industrialisation.
What are the CO2 per capita rankings for China, the USA, and India?
China is ranked 55th
The USA 8th
India 127th
What are the consequences of a warming of 4˚C on soil organic carbon from shallow and deep peat?
A warming of 4˚C causes a 40% loss of soil organic carbon from shallow peat and 86% from deep peat.
Name two phenomena that can create tipping points.
Forest dieback and thermohaline circulation are two phenomena that can create tipping points.
