Under the Kyoto Protocol, industrialized countries will reduce their collective emissions of greenhouse gases by how much compared to the year 1990?
5.2%
The Kyoto Protocol reduces the expected emissions in 2010 by how much?
29%
The Kyoto Protocol’s goal is to reduce overall emissions over what five-year period?
2008-2012
What is the Kyoto’s Protocol reduction target for the European Union?
8%
What is the Kyoto’s Protocol reduction target for the US?
7%
What is the Kyoto’s Protocol reduction target for Japan?
6%
What is the Kyoto’s Protocol reduction target for Russia?
0%
What is the Kyoto’s Protocol reduction target for Australia?
Australia is permitted an 8% increase.
What is the Kyoto’s Protocol reduction target for Iceland?
Iceland is permitted an 10% increase.
What is the limit temperature rise as per the Paris Agreement?
2 degrees Celsius.
The Paris Agreement is the first universal what?
Climate agreement.
The Paris Agreement promises $100 billion a year in climate finance for which types of countries?
Developing nations.
As per the Paris Agreement, 186 countries submitted plans detailing the reduction of what type of pollution?
GHG emissions.
The Paris Agreement seeks carbon neutrality by what year?
2050
By which method is heat transferred from the sun to the earth?
Radiation.
The maximum rate at which heat can be radiated by a body at a given temperature is given by what equation?
The Stefan-Boltzmann equation:
Qmax = σAT^4
Describe the components of the Stefan-Boltzmann equation.
σ is the Stefan-Boltzmann constant (5.67 X 10^-8 W/m^2-K^4), A is the surface area of the body (m^2), and T is the absolute temperature of the body (K).
An object radiating at the maximum possible rate is known as what?
As a black body.
Define heat flux.
The rate of heat transfer per unit of surface area.
What is the relationship between heat flux and the maximum rate of radiation?
q = Qmax/A
Why doesn’t earth’s surface approximate a black body?
Because of the greenhouse effect.
