New research highlights the "incredible challenge" of reaching the Paris Agreement without intense action and details the extreme temperatures parts of the planet will suffer if countries fail to reduce emissions.
The world reached an agreement in December 2015 on curtailing greenhouse gas emissions with the goal of avoiding a 2-degree Celsius increase in average global temperature above pre-industrial levels. Ideally, the treaty's goal is to limit this increase to 1.5 degrees Celsius. The United States delivered notice to the United Nations in August 2018 of the country's intention to withdraw from the Paris Agreement, joining Syria as one of only two countries in the world not party to the treaty.

Two new studies published in the AGU journals Geophysical Research Letters and Earth's Future now show some of the goals set forth in the agreement might be difficult to reach without much sacrifice.
The new research shows future climate extremes depend on the policy decisions made by major emitters, and that even if major emitters were to strengthen their commitments to reducing emissions, the rest of the world would have to immediately reduce their greenhouse gases to zero to achieve the Paris 2015 goal.

"Simply put, these papers highlight the incredible challenge the 2015 Paris Agreement presented to the world," said Dáithí Stone, a climate scientist with the National Institute of Water and Atmospheric Research, a crown-owned research company in New Zealand, who was not involved in either of the studies.
The first study, published in AGU's Geophysical Research Letters, found none of the world's major carbon emitters, including the U.S., China and the European Union, have made commitments calculated to align with limiting climate warning to a 2-degree Celsius increase above pre-industrial levels.
