NASA has released a report that concludes human-induced climate change has not impacted the planet.
The study is a follow-up to an investigation of climate change conducted in the 1980s, when the agency said it was not in a position to definitively attribute human activity to climate change.
But it also found that it is possible humans are not contributing to climate disruption.
“The study, released Wednesday, found that, while climate change can alter patterns and events in the atmosphere, it does not alter the underlying climate system itself,” NASA said in a statement.
“We also find no evidence that humans have caused or are causing climate change.”
NASA also said it has taken steps to address climate change, including: Establishing a National Climate Assessment Task Force, which includes scientists, government agencies, and businesses to gather information on climate change and how to address it; conducting climate change studies in government laboratories, including at universities; and collaborating with private industry and academia on research on climate.
The agency said the study was based on its assessment of the science and was not a final assessment.
The report said climate change will affect many parts of the planet, from agriculture to agriculture production to water supply.
Scientists say climate change could have significant negative impacts on agricultural systems and water resources, especially if climate change exacerbates severe droughts.
In some areas, such as California, drought is projected to become more severe and widespread in the coming decades.
