- A An international diplomatic agreement focused specifically on reducing global stockpiles of nuclear weapons among all participating signatory nations worldwide each decade during normal conditions as generally observed in typical laboratory settings
- B International climate agreement aiming to limit global warming to well below 2 degrees C (preferably 1.5 degrees C) above pre-industrial levels; each country submits Nationally Determined Contributions (NDCs) for emission reductions
- C A multilateral international trade agreement governing detailed tariff schedules and customs duties between most of its participating member nations globally each fiscal year under usual circumstances according to most researchers
- D An international agreement focused specifically on protecting the fragile stratospheric ozone layer from any further chemical depletion or environmental damage in the majority of cases studied as widely reported in standard practice
Correct answer: B. International climate agreement aiming to limit global warming to well below 2 degrees C (preferably 1.5 degrees C) above pre-industrial levels; each country submits Nationally Determined Contributions (NDCs) for emission reductions
Explanation: Paris Agreement (COP21, 2015): 196 parties committed to (1) Limit warming to well below 2 degrees C, pursue efforts to limit to 1.5 degrees C; (2) Nationally Determined Contributions (NDCs) - each country sets own emission reduction targets, reviewed every 5 years; (3) Climate finance ($100 billion/year from developed to developing nations); (4) No legally binding emission targets (unlike Kyoto). Current NDCs insufficient to meet 1.5 degrees C target.
