The countries most affected by the effects of climate change will be low-lying nations, particularly vulnerable to sea level rise, and developing countries that do not have the resources to adapt to changes in temperature and precipitation. But prosperous nations like the United States are also increasingly vulnerable. In fact, millions of Americans – especially children, the elderly and the poor – are already suffering from the wrath of climate change. William Nordhaus of Yale University writes for foreign affairs and thinks about how to remedy the failure of the world`s climate efforts. It is rare that there is a consensus among almost all nations on a single subject. But with the Paris agreement, world leaders agreed that climate change was driven by human behaviour, that it was a threat to the environment and to humanity as a whole, and that global action was needed to stop it. In addition, a clear framework has been put in place for all countries to make commitments to reduce emissions and strengthen these measures over time. Here are some main reasons why this agreement is so important: 1995 – The first Conference of the Parties (COP1) on the UNFCCC was held in Berlin. The parties agreed that the UNFCCC mechanisms were insufficient and accepted the so-called Berlin mandate, which allows the parties to make concrete commitments. Non-Schedule 1 countries are exempt from additional obligations.
Yes, there is broad consensus within the scientific community, although some deny that climate change is a problem, including politicians in the United States. When negotiating teams meet for international climate talks, «there is less skepticism about science and more disagreement about how to set priorities,» said David Victor, professor of international relations at the University of California, San Diego. The basic science is that: This CFR timeline has been following UN climate talks since 1992. A study published in 2018 shows a threshold where temperatures could rise to 4 or 5 degrees (ambiguous expression, continuity would be «4-5 degrees Celsius») compared to pre-industrial levels, compared to pre-industrial levels, thanks to returns of self-amplitude in the climate system, indicating that this threshold is below the 2-degree temperature target agreed in the Paris climate agreement. Study author Katherine Richardson points out: «We find that in its history, the Earth has never had a nearly stable state, warmer than that of pre-industrial, and suggests that there is a significant risk that the system itself, because of all these other processes, will want to continue warming, even if we stop emissions. This means not only reducing emissions, but much more.  In the context of this debate, important climate agreements have developed in their pursuit of emissions reductions. The Kyoto Protocol only required industrialized countries to reduce their emissions, while the Paris Agreement recognized that climate change was a common problem and called on all countries to set emission targets. Countries must, among other things, report on their greenhouse gas inventories and their progress against their targets, so that external experts can assess their success. Countries should also review their commitments by 2020 and present new targets every five years to further reduce emissions. They must participate in a «comprehensive state of affairs» to measure collective efforts in order to achieve the long-term goals of the Paris Agreement.
