Climate-related impacts such as the wildfires in the western United States will only become more severe if we allow the worst-case scenario to unfold by 2100. A new EarthTime visualization shows just how hot the world may become in 2100, within the life expectancy of today’s tween, 10-12-year olds.
The findings, announced at the fourth World Economic Forum Sustainable Development Impact Summit, place even more urgency on business and government leaders to fast-track solutions and act now to prevent such a scenario unfolding.
Experts attempting to rank the severity of climate change scenarios likely to play out by the year 2100 refer to the worst of them as “RCP 8.5.” This entails more than 4°C in warming above pre-industrial levels, rising emissions, hundreds of millions of people being forced to migrate, and a big increase in forested area prone to the type of fires that have raged this summer (due to a phenomenon dubbed the “moisture deficit”).
The World Economic Forum has used data from the Climate Impact Lab, Climate Central, the Washington Post, and NASA satellites to create a visualization of this worst-case scenario.
The data model shows that by 2100:
Average June-August temperatures reach 38°C (100.4°F) for many parts of the world
New Delhi, India, has eight months a year with temperatures averaging 32ºC (89.6°F) up from six
Phoenix, Arizona, has nearly 200 days a year of temperatures hitting at least 32ºC (89.6°F)
Regions of southern Europe average June-August temperatures of 30°C (86°F)
Viet Nam, Cambodia, Malaysia and Indonesia’s June-August temperatures average more than 30°C (86°F)
Miami and Fort Lauderdale, Florida, disappear under water due to rising sea levels
“Longer-term trends can often seem abstract and intangible,” said Stephan Mergenthaler, Head of Strategic Intelligence at the World Economic Forum. “Visualizing the effects of these trends, based on the latest scientific data, can help people take action and work towards shared goals.”
Experts agree that the worst impacts of climate change can be avoided if we limit global warming to below 2ºC above pre-industrial levels. Effective climate policies, fighting efforts to discredit legitimate science, removing carbon dioxide from the atmosphere or offsetting it by planting new forests, and upgrading transportation and energy systems can all be part of the equation.
“To speed up the delivery of the Sustainable Development Goals and create change, we need to get as many people involved as possible,” said John Dutton, Head of UpLink at the World Economic Forum. “Anyone can make an impact. We have seen the next generation of change-markers and social entrepreneurs stand up and create action plans on the UpLink platform to make sure we don’t see this visualization come true. Connecting these ideas to funding sources, scaling up impact and creating a community of support will help us address the critical opportunities ahead for this generation.”
Innovative projects on the UpLink platform include how to reduce emissions by buying and selling unused shipping container space, how to use waste management and data analytics to reduce plastic in the ocean, and how to create packaging made from sustainably farmed seaweed. Projects allow start-ups to flag what they need to succeed and connect them with software developers, funders, or resources to deliver impact.
80 EarthTime Stories
The climate visualization is one of nearly 80 EarthTime stories that have so far been published alongside hundreds of related topics on the Forum’s Strategic Intelligence platform. They cover a broad range of issues including environmental protection, technology development, intellectual property trends and systemic racism. These visualizations are intended to help illustrate important global trends and dynamics in an easy-to-understand, readily accessible way.
