The science is clear: our climate is heating rapidly. The average global temperatures have increased by 1.2 degrees Celsius since 1880, particularly in the late 20th century. The concentration of atmospheric CO2, the GHG that contributes more than 2/3 to global warming, is at its highest level ever. The Intergovernmental Panel on Climate Change (IPCC) steadily points out that human activities have warmed the atmosphere, ocean and land, producing widespread and rapid changes in the atmosphere, ocean, cryosphere and biosphere. Due to these changes in climate, the number of weather, climate and water-related disasters has increased by a factor of five over the past 50 years, causing over 2 million deaths and US$3.64 trillion in losses.
According to IPCC, warming beyond 1.5 degrees could have irreversible and irreparable consequences. However, effective and equitable adaptation and mitigation actions can significantly reduce vulnerability and contribute to climate resilience. To limit global warming to well below 2, preferably 1.5 degrees Celsius, compared to pre-industrial levels, countries came together to hold themselves accountable under the Paris Agreement. The agreement is a milestone of international cooperation to tackle climate change – first legally binding document in the history of climate action.
To move fast in the race against climate crisis, targeted actions that bring tangible benefits and limit the trade-offs on multiple fronts, are key for common success against climate change. The 2030 Agenda and the Sustainable Development Goals (SDGs), the world’s plan of action to achieving sustainability and resilience for people and planet, are closely linked with climate. Maximizing on the interlinkages between the 2030 Agenda and the Paris Agreement by leveraging Climate and SDG Synergies, has the potential of achieving both agendas and guaranteeing a livable future for next generations by leaving no one behind. In fact, progress made towards limiting global temperature increase would significantly ease the path to many other SDGs, such as those related to poverty, hunger, access to water, and terrestrial and marine ecosystems. Many of the SDGs and their targets can also be achieved in ways that would enable adaptive responses to climate change, for example those related to resilience in SDGs 9 and 11, respectively relating to infrastructure and urban settlements.
UN DESA is moving the needle forward for harnessing synergies across development and climate action. Through its support to various intergovernmental processes and fora, UN DESA is working to improve coordination with other entities by using the 2030 Agenda as both a framework and guiding principles.
