Scientists say that hurricane rainfall was 10% more in 2020 due to the climate crisis.


The study was published in the journal. Nature CommunicationsGlobal warming boosted hourly rainfall rates of tropical storms and hurricanes by 5-10%, according to the study. When they looked at only hurricanes — the strongest storms — the increase was 8 to 11%.

“That means that climate change is not only impacting our hurricane seasons, but it is also impacting the most severe storms a bit more,” Kevin Reed of Stonybrook University, who is a climate and hurricane scientist and lead author of this study, told CNN. “The key takeaway is that climate changes are here and that they’re already affecting our hurricane season,” Reed said.

Hurricanes — also called tropical cyclones or typhoons outside North America — are enormous heat engines of wind and rain, feeding on warm ocean water and moist air. Over the years, scientists have become more confident in the severity of the climate crisis. Making them more potent.
Storm surge is caused by flooding from rainfall. second-biggest killerIn landfalling tropical storms and hurricanes. Tuesday’s study indicates that the threat to the region has increased over the past few decades. It will likely increase further in the future because warmer air can store more water vapor which leads directly to higher rainfall rates.
The 2020 Atlantic hurricane season had 30 named storms, making it the most active ever recorded. Because the season was so destructive of the alphabet, officials had no choice but to use Greek letters to name their storms starting in September. Twelve storms were named and made landfall along the US coast, including Laura Delta, which decimated parts of the Gulf Coast.
Climate change attribution is the science of how much human-caused global warming has played in certain extreme weather events. made significant advancesAccording to the UN Intergovernmental Panel on Climate Change, it has been a decade. Scientists predict that as humans continue to add greenhouse gases to the atmosphere, the Earth’s temperature will rise and hurricane impacts will worsen.

CNN was told by Allison Wing, a Florida State University climate researcher, that the study is in line with what scientists had predicted.

19 named storms expected this hurricane season, above average but becoming more common, CSU forecast says

Wing stated that the study, which is consistent with expert assessments, suggests that hurricane rainfall will continue increasing with future warming. Wing spoke to CNN. “Overall, this study confirms our expectation that stronger and wetter storms are more likely in a warmer world.”

Reed stated that climate change is accelerating and he expects stronger storms to have higher rainfall rates.

Reed stated that “If Hurricane Katrina was to have occurred in 2022, then the rains from that storm would be greater than in 2005.” “All of the historical records that we have in the past; when New York plans to ensure that Hurricane Sandy doesn’t impact the same way as 2012, we need to plan for how Hurricane Sandy will look in 2030 or 2040.”

Reed said that hurricane season will have worsening effects unless the world changes its course and reduces fossil fuel use.

Reed stated, “Climate Change is not just something that will happen 70 years from now. It’s here and it is affecting our weather on an everyday basis.” “We need adapt and make systems more resilient. However, we must use this information to inform decision-making on how to reduce our dependence upon fossil fuels that generate these greenhouse gases.

Scientists have also reported a significant change in hurricanes in the USA in 2020: They are now Maintaining their strengthThey can still make landfall long after they have made it. Hurricanes tend to weaken when they cross land because they are no longer able to access the warm ocean water they need. This change has led to more severe impacts in areas further inland than they experienced in decades past.
