Paris Agreement at 10: Climate Goals Slip as World Faces Mounting Crises
Table of Contents
A decade after the landmark Paris Agreement aimed to limit global warming, the world is falling behind schedule, facing increasingly dire consequences from climate change – and a growing sense of frustration that political will is lagging.
Ten years ago today, on December 12, 2015, leaders from 195 countries convened at the United Nations Climate Change Conference (COP21) in France and ratified the Paris Agreement, a moment widely hailed as historic. The agreement committed signatory nations to “strengthen the global response to the threat of climate change,” with the ambitious goal of keeping the global average temperature increase “well below 2°C above pre-industrial levels” and pursuing efforts to limit it to 1.5°C.
However, a recent report from the United Nations Environment Programme (UNEP), published on November 4, paints a grim picture. Temperature rise projections for this century are now estimated to be between 2.3 and 2.5°C, with projections reaching 2.8°C based on current policies. “We will not be able to keep global warming below 1.5°C in the next few years. Exceeding this limit is inevitable,” warned UN Secretary-General António Guterres.
The path forward is further complicated by political headwinds. During his first term, former US President Donald Trump withdrew the United States from the Paris Agreement, citing concerns that the agreement did not reflect US values. This decision underscored the fragility of international cooperation on climate action.
A Looming Humanitarian Crisis: Climate-Driven Migration
The consequences of a warming planet are already being felt worldwide, and the potential for large-scale displacement is a growing concern. The World Bank warned in September 2021 that global warming could force up to 216 million people to migrate within their own countries by 2050, seeking better living conditions. This migration will be driven by declining water availability, reduced agricultural productivity, and the increasing threat of sea-level rise and storm surges.
Europe is particularly vulnerable, identified as the fastest-warming continent and bearing the brunt of extreme weather events. Earlier this year, Celeste Saulo, Secretary General of the World Meteorological Organisation (WMO), highlighted the continent’s escalating climate risks.
From Fires to Floods: A Year of Climate Extremes
Recent years have been marked by a series of devastating climate-related disasters. Last August, major wildfires ravaged Portugal and Greece, with over 150 fires detected in a single day. In October 2024, the Valencia region of Spain was struck by catastrophic flooding, receiving a year’s worth of rainfall in just eight hours, resulting in over 220 fatalities. Just a month prior, Storm Boris caused deadly floods in Central Europe, claiming more than twenty lives.
These events are not isolated incidents. In France, temperatures have already risen by 2.1°C over 2015-2024 compared to 1900-1930 levels, and are projected to reach 4°C by 2100 under a 3°C global warming scenario, according to Météo-France. Each degree of warming increases the air’s capacity to hold water vapor by approximately 7%, intensifying rainfall, while simultaneously diminishing the ocean’s ability to absorb carbon dioxide. The ocean currently stores 91% of the excess heat from greenhouse gas emissions, but its capacity is waning.
This disruption will exacerbate sea-level rise and lead to more frequent and intense heatwaves, droughts, and extreme rainfall events.
A Call for Systemic Change
A UN report published on December 9, compiled by 287 scientists from 82 countries, urgently calls for an “interconnected, whole-of-society and whole-of-government” approach to tackling the climate challenge. The report warns that climate change could reduce annual global GDP by 4% by 2050 and cost millions of lives if nations fail to transform energy and food systems.
Growing Activism and Accusations of “Climate Sabotage”
Frustration with the lack of progress is fueling increased activism. On Thursday, climate associations including Greenpeace, Action Justice Climat Paris, and ANV-COP 21 staged a protest near the Eiffel Tower, displaying a banner featuring prominent political figures – including Emmanuel Macron, Marine Le Pen, and Donald Trump – to denounce what they see as a prioritization of polluting industries and wealthy interests over climate action.
Greenpeace concluded that “misinformation is on the rise, the criminalisation of environmentalists is on the increase, and ecological setbacks are multiplying,” particularly criticizing France for failing to meet its climate targets. “Climate sabotage is not inevitable; it is the result of political choices dictated by private interests rather than the general interest,” the organization stated.
Experts emphasize the need for integrated policies addressing climate change, biodiversity loss, land degradation, and pollution. The authors of the UNEP’s quadrennial Global Environment Outlook report, released earlier this week, argued that these issues are inextricably linked and require increased investment in transitioning away from fossil fuels, promoting sustainable agriculture, curbing pollution, and reducing waste.
Bob Watson, a lead author of the report and former NASA and British climate scientist, stressed the urgency of the situation: “What we’re saying is we can become much more sustainable, but it will take unprecedented change to transform these systems. It has to be done rapidly now because we’re running out of time.”
