Was Trump's withdrawal from Paris Agreement a blessing in disguise?

Although the Kyoto Protocol (1997) obligated countries to mitigate global emissions, fundamental differences between the developed and developing world on who should bear the cost of climate change had rendered it stagnant.

Consensus was finally achieved with the Paris Agreement (2015), whereby countries agreed to take measures to keep global temperatures under 2 degree Celsius, albeit with no mechanisms to make countries comply.

Although President Bill Clinton signed the Kyoto Protocol, the Senate refused ratification stating it put the US economy at a disadvantageous position. President Bush in 2002 withdrew from the Agreement, echoing the same reasons, causing it to fall apart.

While President Obama promised to cut down 26-28% % emissions from 2005 levels by 2025, Trump pulled out of the Agreement in early June.

Reacting to Trump's withdrawal, Mayors of 175 cities including Pittsburgh Mayor Bill Peduto re-affirmed their cities' commitment to the Agreement. While Hawaii enacted a legislation backing Paris commitments, states including California are already pioneering climate action in the US.

Former New York Mayor and C40 Chairman, Michael Bloomberg promised that US will still meet its commitments through a network of states, cities and businesses.

Cities have tremendous economic and political clout. They further consume two-thirds of the world's energy and 70% of the world's carbon dioxide emissions. Moreover, impacts of climate change including rising sea-levels directly impact cities in coastal areas.

International collectives such as the Cities Climate Leadership (C40) also allow them the flexibility to try out innovative frameworks for effective transfer of technology and finances.

Indian Mayors have started taking into account the financial risks of climate change, driving city-level climate action across India.

For instance, Surat, a victim of repeated floods and a plague outbreak in 1994 has put in excellent resilient systems including early warning systems and ground water management.

Post the devastating 2015 floods, Chennai is reported to be looking into similar strategies.

Cities have strong incentives to address climate change from environmental as well as economic benefits that they would derive. Further, climate change can only be effectively tackled through co-operation between cities and private entities, along with states.

Trump's withdrawal if anything is a blessing in disguise, for having mobilized the entire international community into action, possibly even exceeding expectations under the Paris Agreement.
