Which potent greenhouse gas class is the Kigali Amendment to the Montreal Protocol designed to phase down?

Answer

The Kigali Amendment to the Montreal Protocol, adopted in 2016, is designed to phase down the production and consumption of Hydrofluorocarbons (HFCs). HFCs are powerful greenhouse gases that were introduced as replacements for ozone-depleting substances (ODS) like CFCs and HCFCs, which were the original focus of the Protocol. The Amendment is expected to prevent up to 0.5 degrees Celsius of global temperature rise by 2100.

Which property primarily makes a greenhouse gas highly potent (high GWP)?

Answer

The Global Warming Potential (GWP) of a gas is determined by its atmospheric lifetime and its radiative efficiency (the ability to trap heat). Gases with a high capacity for absorbing infrared radiation (a measure of radiative efficiency) are highly potent because each molecule traps a large amount of outgoing terrestrial heat. A long atmospheric lifetime further contributes to a high GWP over a specified time horizon (e.g., 100 years).

Which renewable energy source is classified as a baseload power provider due to its constant and stable output?

Answer

Baseload power sources provide a constant, stable supply of electricity. Unlike intermittent sources like solar (dependent on sun) and wind (dependent on wind speed), Geothermal power extracts heat from the Earth's interior, providing a consistent energy flow that is not affected by daily or seasonal weather variations, thus classifying it as a dispatchable, baseload source.

What is the primary cause of cultural eutrophication in freshwater bodies?

Answer

Cultural eutrophication is the acceleration of the natural aging process of water bodies due to human activity. It is primarily caused by excessive input of limiting nutrients, mainly nitrates and phosphates, from sources like agricultural and urban runoff. This over-enriches the water, leading to algal blooms and subsequent oxygen depletion (hypoxia).

Which Kyoto Protocol mechanism allows Annex I nations to fund emission reduction projects in Non-Annex I nations for certified credits?

Answer

The Clean Development Mechanism (CDM) is one of the Kyoto Protocol's three flexible mechanisms. It allows industrialized countries (Annex I) with emission reduction commitments to invest in emission reduction projects in developing countries (Non-Annex I). In return, they receive Certified Emission Reduction (CER) credits, which they can use to meet their own emission targets. This promotes sustainable development in Non-Annex I countries while helping Annex I countries meet their commitments cost-effectively. Distractors: - Joint Implementation (JI) allows Annex I countries to trade Emission Reduction Units (ERUs) from projects in *another* Annex I country. - Emissions Trading Scheme (ETS) allows Annex I countries to trade Assigned Amount Units (AAUs) among themselves. - Global Stocktake (GST) is a process under the Paris Agreement (not Kyoto) to assess collective progress.

Which renewable energy source consistently provides the highest capacity factor?

Answer

Geothermal power plants utilize continuous heat from the Earth's interior, enabling them to operate as a baseload power source with typical capacity factors often exceeding 90%, which is the highest among major renewable energy sources.
