"There are many reports based on scientific research that talk about the
long-term impacts of climate change — such as rising levels of greenhouse
gases, temperatures and sea levels — by the year 2100. The Paris Agreement, for
example, requires us to limit warming to under 2.0 degrees Celsius above
pre-industrial levels by the end of the century.
Every few years since 1990, we have evaluated our progress through the
Intergovernmental Panel on Climate Change’s (IPCC) scientific assessment
reports and related special reports. IPCC reports assess existing research to
show us where we are and what we need to do before 2100 to meet our goals, and
what could happen if we don’t.
The recently published United Nations assessment of Nationally Determined
Contributions (NDCs) warns that current promises from governments set us up for
a very dangerous 2.7 degrees Celsius warming by 2100: this means unprecedented
fires, storms, droughts, floods and heat, and profound land and aquatic
While some climate projections do look past 2100, these longer-term projections
aren’t being factored into mainstream climate adaptation and environmental
decision-making today. This is surprising because people born now will only be
in their 70s by 2100. What will the world look like for their children and
To grasp, plan for and communicate the full spatial and temporal scope of
climate impacts under any scenario, even those meeting the Paris Agreement,
researchers and policymakers must look well beyond the 2100 horizon."
