“We are entering the uncharted territory of climate change”: Climate Scientist

The remnants of Hurricane Ada killed dozens of people and triggered flash floods in the tri-state region, marking the latest extreme weather event in this summer full of climate-related disasters.

For Jin Cobb, who Co-authored the landmark United Nations climate change scientific report, The intensity of the storm once again reminds people how human activities have fundamentally changed the earth’s atmosphere.

“With climate change, we are entering uncharted territory,” said Cobb, director of the Georgia Institute of Technology’s Global Change Program. “The climate we have been living in will not be the climate we live in now, nor will it be the climate in the next few decades.”

The weather caused by the remnants of Hurricane Ida brought record rainfall to the area. Newark, New Jersey received 8.41 inches of rain on Wednesday. Making it the most rainy day on recordIn New York City, rainfall reached 3.15 inches in one hour, more than any record in the city since the 1800s. Central Park alone is almost twice the rainfall record set in 1927. According to the National Weather Service.

“These rains are far breaking records. It reminds me of the shocking heat wave we saw in the Pacific Northwest earlier this summer,” Cobb said. “It’s jaw-dropping.”

Cobb’s research is included in the United Nations report issued by the Intergovernmental Panel on Climate Change, which clearly pointed out that the frequency of events like Hurricane Ida and the intensity witnessed from the Gulf Coast to the Northeast this week will only increase, no matter what is taken now. Kind of climate action. Cobb said that as global temperatures may rise by about 1.5 degrees Celsius in the next 20 years, hot heat waves and wildfires, as well as heavy rains and floods will only escalate with each additional increase in warming.

The impact of the recent storm has raised questions about the resilience of the U.S. transportation system and broader infrastructure and its ability to withstand extreme weather events. The flood flooded New York City’s train system, passengers were trapped, and New York Mayor Bill de Blasio had to urge residents to stay away from roads and subways.in a Interview with CNBCJanno Lieber, Acting Chairman and CEO of the Metropolitan Transportation Authority (MTA) in New York City, said the system urgently needs to be upgraded.

“We really have to work with friends from the city government to ensure that the street drainage system has a larger capacity so that we don’t get as much water into the subway system under these new climate change era flooding conditions. “Lieber said.

President Joe Biden responded to this sentiment.

Biden said: “For this country, the hurricane Ida and wildfires in the west and unprecedented flash floods in New York and New Jersey in the past few days remind people that these extreme storms and climate crises are here.” “We need to take action.”

The Infrastructure Act passed by Congress allocates millions of dollars to upgrade the subway system and roads. Local, state, and federal lawmakers vowed to cooperate and invest in climate resilience to strengthen preparations for future climate events. But Cobb said that given the speed and change of warming, their options may be limited.

“The extent to which this infrastructure can adapt to such storms is limited, which shows the need to develop deep and continuous emission reduction measures to limit future climate risks and losses to the middle of this century,” she said. “We have locked in another few tenths of a degree Celsius, but our choices in the next 10 or 20 years will determine how hot it will become by the middle of this century.”
