NASA is launching a new online tool that allows anyone to see what the sea ​​level anywhere in the world for years to come. The tool was created by the agency's sea level change team and aims to demonstrate how the climate changes they can affect areas that are densely populated.

The tool is fed with data from the Intergovernmental Panel on Climate Change (IPCC) and seeks to facilitate public access to this data and help public authorities, in different spheres, to plan and try to reduce the effects of climate change in these areas. The tool is hosted on NASA's Sea Level Portal.

The tool has interactivity features, which allow users to click anywhere on the global ocean and coast and choose the year to be monitored between the 2020s and 2150s. The tool will deliver a detailed report for the chosen location, based on the Sixth Assessment Report of the IPCC, released this Monday (9).

Every five or seven years the IPCC provides global-scale assessments of the Earth's climate, with reports being released since 1988. The focus of the documents is on temperature changes, of the ice cover, greenhouse gas emissions and sea level variations across the planet, based on satellite data, solo instruments and computer simulations.

However, for the first time, the report gains a graphical dimension and easy access for the general public, allowing a localized view with the help of an online tool. According to NASA, this type of tool can facilitate the process of reading and understanding the IPCC reports.

In addition to providing an easy view of the projections of the IPCC reports, the tool works with different variables, which involve changes in the socioeconomic scenario of nations and greenhouse gas emissions, being possible, for example, to apply a scenario in which the Agreement Paris is fully complied with, or a scenario in which emissions remain the same.

How to use the tool:

NASA's new tool is very intuitive and easy to use. To check possible scenarios in a given area, just:

Access to sea ​​level projection tool, then choose a location on the map. When you click on a certain point, a pop-up will show the average increase for that area. For more detailed data, just click on “full projection”.

By clicking on this option, the user is redirected to another page, where it is possible to browse the different scenarios, which are based on the Shared Socioeconomic Pathways (SSP), ranging from scenarios with little or no change in greenhouse gas emissions , to scenarios with significant emission reductions.
