Get THE THIRD NATIONAL

UNEP | Emissions Gap Report 2023 This report by the UN Environment Programme (UNEP) finds that current pledges under the Paris Agreement put the world on track for a 2.5-2.9°C temperature rise above pre-industrial levels this century – far above the 1.5°C limit that would avoid the worst impacts of climate change.

The Fifth U.S. National Climate Assessment, released on November 14, 2023, demonstrates how climate change is affecting America's working lands, how communities are reducing their risks, and how winning solutions to climate change can be found in productive landscapes.

Synthesis of the Third National Climate Assessment for the Great Lakes Region. Intense rainstorms, floods, and heat waves will become more common in the Great Lakes region due to climate change in the coming decades.

Final versions of the Third NCA and Highlights were adopted by NCADAC on May 6, 2014, and submitted to the Federal government. The Public Review Draft, Government Review Draft, and NCADAC-approved Final Report can be found below.

The first NCA was released in 2000. Between 2002 and 2009, USGCRP produced 21 assessment products centered around five scientific goals, and then in 2009 released NCA2. The third report (NCA3) was published in 2014, and the NCA4 in 2018.

Threats to the Great Lakes' ecosystems, include invasive species, climate change, pollution, and habitat destruction. Climate change affects water temperatures, weather patterns, and lake levels.

These lake surface temperatures are projected to rise by as much as 7°F by 2050 and 12.1°F by 2100. Higher temperatures, increased precipitation, and lengthened growing seasons are likely to result in increased production of blue-green and toxic algae in the lakes.

Climate Change Impacts in the United States: The Third National Climate Assessment. The National Climate Assessment summarizes the impacts of climate change on the United States, now and in the future.

The IPCC Third Assessment Report (TAR), Climate Change 2001, is an assessment of available scientific and socio-economic information on climate change by the IPCC. Statements of the IPCC or information from the TAR were often used as a reference showing a scientific consensus on the subject of global warming.

Mean annual precipitation varies from 50 cm in the west to 70-80 cm in the eastern parts of the region. Annual summer temperatures average 14oC to 15.5oC, while winter temperatures average -13oC. Climatic variation arises from location relative to the Great Lakes.
