A locked-down pandemic-struck world cut its carbon dioxide emissions this year by 7%, the biggest drop ever, new preliminary figures show.The Global Carbon Project, an authoritative group of dozens of international scientists who track emissions, calculated that the world will have put 37 billion U.S. tons (34 billion metric tons) of carbon dioxide in the air in 2020. That’s down from 40.1 billion US tons (36.4 billion metric tons) in 2019, according a study published Thursday in the journal Earth System Science Data.Scientists say this drop is chiefly because people are staying home, traveling less by car and plane, and that emissions are expected to jump back up after the pandemic ends. Ground transportation makes up about one-fifth of emissions of carbon dioxide, the chief man-made heat-trapping gas.“Of course, lockdown is absolutely not the way to tackle climate change,” said study co-author Corinne LeQuere, a climate scientist at the University of East Anglia.The same group of scientists months ago predicted emission drops of 4% to 7%, depending on the progression of COVID-19. A second coronavirus wave and continued travel reductions pushed the decrease to 7%, LeQuere said.Emissions dropped 12% in the United States and 11% in Europe, but only 1.7% in China. That’s because China had an earlier lockdown with less of a second wave. Also China’s emissions are more industrial based than other countries and its industry was less affected than transportation, LeQuere said.The calculations — based on reports detailing energy use, industrial production and daily mobility counts — were praised as accurate by outside scientists.Even with the drop in 2020, the world on average put 1,185 tons (1,075 metric tons) of carbon dioxide into the air every second.Final figures for 2019 published in the same study show that from 2018 to 2019 emissions of the main man-made heat-trapping gas increased only 0.1%, much smaller than annual jumps of around 3% a decade or two ago. Even with emissions expected to rise after the pandemic, scientists are wondering if 2019 be the peak of carbon pollution, LeQuere said.“We are certainly very close to an emissions peak, if we can keep the global community together,” said United Nations Development Director Achim Steiner.Chris Field, director of the Stanford Woods Institute for the Environment, thinks emissions will increase after the pandemic, but said “I am optimistic that we have, as a society learned some lessons that may help decrease emissions in the future.”“For example,” he added, “as people get good at telecommuting a couple of days a week or realize they don’t need quite so many business trips, we might see behavior-related future emissions decreases.”___Follow AP’s climate coverage at https://www.apnews.com/Climate___Follow Seth Borenstein on Twitter at @borenbears .___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

A Delavan, Wisconsin woman thought she was gaining weight, but it turned out to be something much more serious. Tina Ferguson had 30 pounds of tumors in her stomach from a rare type of cancer.“I just thought it was middle age and weight gain," said Ferguson. "You have no idea you have something inside you that is killing you."A trip to the doctor gave her a diagnosis of ovarian cancer that was possibly benign. But when the doctor's opened her up to remove it they found something unexpected."I will never forget them coming in the room and saying, 'This is stage 4. You have appendix cancer,'" Ferguson said.On top that, it had ruptured attaching tumors to other organs and leaving a jelly-like substance called mucin in the lining of her abdomen. There was 30 pounds of it inside of Ferguson pushing on her organs."This is the mucin and tumor that's present inside of the abdomen before Tina had her operation," said Dr. Harvershp Mogal, a cancer surgeon at the Medical College of Wisconsin.It took doctors 12 hours to remove all the tumors and mucin. The rare cancer used to come with a very low survival rate. Ferguson was first told she only had months to live.However, Froedtert & the Medical College of Wisconsin used a new kind of chemotherapy called Hyperthermic intraperitoneal chemotherapy (HIPEC) to wash the tumors out."I basically give the patient a heated chemotherapy wash for about 90 minutes. The chemotherapy is heated to 108 Fahrenheit and what the chemotherapy does it takes care of any minute cancer cells that we can't see," said Mogal.Mogal said Ferguson is now cancer-free, just six months later."It's changed my entire outlook on life. You know almost dying, you can't take anything for granted. Every day is a gift," said Ferguson. 1798

A dire warning from the National Weather Service has forced an evacuation around the College Lake Dam in Lynchburg, Virginia.A flash flood warning issued Thursday night by the NWS reports "if a complete failure of the dam occurs, the water depth at Lynchburg could exceed 17 feet in 7 minutes." The area impacted would be the city of Lynchburg, which is one mile downstream from the dam.An updated report issued just after midnight by the NWS said the dam has not failed, and is being closely monitored by emergency personnel for any signs of structural failure."Lynchburg Water Resources Department reported that 4 to 6 inches of heavy rain earlier in the evening caused College Lake to fill beyond its capacity.Piper Van dePerre, with the Lynchburg Department of Emergency Services, told CNN affiliate WDBJ that crews are working with a list of 124 residences that need to be evacuated because of the imminent threat of a dam break. It's not certain if all the structures are occupied along the rain swollen Blackwater Creek.The University of Lynchburg, which is nearby, says it has not ordered an evacuation because it is not downstream of the dam, according to affiliate WSLS.The CNN Weather Center said there a forecast of 1-3 inches of rain through Friday evening and that rain hasn't been above average, but the runoff is a contributor to the area flooding.The-CNN-Wire 1384

A federal judge halted construction of the controversial Keystone XL oil pipeline on Thursday, in a blow to the Trump administration and a win for environmental groups.US District Judge Brian Morris found that the US government's use of a 2014 environmental review to justify issuing a presidential permit for construction of the cross-border pipeline violated the National Environmental Policy Act, the Endangered Species Act and the Administrative Procedure Act, according to the court order issued Thursday."The Court enjoins Federal Defendants and TransCanada from engaging in any activity in furtherance of the construction or operation of Keystone and associated facilities," the court document reads, "until the Department has completed a supplement to the 2014 SEIS (Supplemental Environmental Impact Statement) that complies with the requirements of NEPA and the APA."Environmental groups involved in bringing the 2017 lawsuit celebrated the decision."Keystone XL would be a disaster for the climate and for the people and wildlife of this country," said Jackie Prange, senior attorney at the Natural Resources Defense Council, one of the plaintiffs. "As the court has made clear yet again, the Trump administration's flawed and dangerous proposal should be shelved forever."In March 2017, President Donald Trump's administration issued a permit approving construction of the pipeline, reversing the Obama administration's decision to block the controversial project.The White House has not responded to CNN's request for comment on the judge's order.The permit approval followed years of intense debate over the pipeline amid steadfast opposition from environmental groups.They argued that the pipeline would support the extraction of crude oil from oil sands, a process that pumps more greenhouse gases into the atmosphere than standard crude oil extraction. They also opposed the pipeline because it would run across one of the world's largest underground deposits of fresh water.Native American groups argued the pipeline would cut across their sovereign lands.The-CNN-Wire 2099
