In other cases, the UNFCCC regime has set out specific forums to combat greenhouse gas emissions. In this context, emissions from international bunker fuels are processed by the International Civil Aviation Organization (ICAO) and the International Maritime Organization (IMO). ICAO has a global market-based mechanism in place to offset emissions from international aviation; More needs to be done within IMO, which has so far adopted only a first GHG strategy. Other critics, for example, that countries have not done enough to combat climate change under the agreement, say more about the nature of the climate animal – and about the lack of political will to tackle it – than about the agreement itself. Moreover, two unexpected events since Paris have further affected enthusiasm for the fight against climate change: the withdrawal of the United States from Paris has probably undermined political will, at least in some countries, and the introduction of a pandemic in 2020 has at least diverted policy attention. However, it is important to remember that the Paris agreement is not static. Instead, it must strengthen countries` national efforts over time – meaning that current commitments are the terrain, not the ceiling, of climate change ambitions. Labor`s emissions – continuing to reduce emissions by 2030 and 2050 – have yet to be implemented and the agreement provides the instruments to ensure that this happens. The IPCC notes that climate change is limited only by a “substantial and sustainable reduction in greenhouse gas emissions.” While the benefits of presenting a single global temperature threshold as a dangerous climate change can be discussed, the general scientific view is that an increase in global temperatures of more than 2 degrees Celsius would be an unacceptable risk – potentially leading to mass extinctions, more severe droughts and hurricanes, and an arid region.
While it is not clear that global warming will cause “sudden and irreversible changes” in Earth`s systems, the risk of exceeding the threshold only increases if temperatures rise. The authors of the agreement have set a withdrawal period that President Trump must follow – which prevents him from irreparably harming our climate. Nicolas Holiber`s old wood carvings highlight the threat that climate change poses to bird towns. The UN report warns that the terrible effects of climate change will come sooner than expected. This is why we need to follow the report`s advice and why every tonne of emissions reduction can make a difference. CFR`s World101 Library explains everything you need to know about climate change. These rules of transparency and accountability are similar to those set out in other international agreements.
