ABOUT TO BEC >>> PRESIDENT BIDEN IS TAKING SWIFT ACTION ON A NUMBER OF ISSUES INCLUDING CLIMATE CHANGE, HE REJOINED THE PARIS CLIMATE ACCORD AND ISSUED A BROAD ORDER TO REVERSE MANY OF THE PREVIOUS ADMINISTRATION'S POLICIES ON THE ENVIRONMENT. >> THIS ORDER PROTECTS THE NATION BY REVIEWING THE BOUNDERS FOR SEVERAL NATIONAL MONUMENTS, AND TEMPORARY MORATORIUM ON ALL OIL AND NATURAL GAS LEASING IN WILDLIFE REFUGE IN THE ARCTIC. >> THESE ARE JUST THE SERIES OF POLICIES THAT ARE EXPECTED. JOINING US NOT TO DISCUSS THE IMPACT IS AN ASSISTANT PROFESSOR OF POLICY AND ENVIRONMENT, ANGEL SUE, GOOD MORNING AND THANK YOU FOR COMING IN.>> HEY. >> LET'S START WITH THE PARIS CLIMATE ACCORD, PRESIDENT DONALD TRUMP PULLED OUT OF THAT AGREEMENT WHICH INVOLVES A THING ABOUT 190 COUNTRIES. WE SHOULD POINT OUT IT IS NOT LEGALLY BINDING SO HOW MUCH DOES IT BENEFIT THE U.S. TO REJOIN THE ACCORD? >> IT REALLY IS SIGNIFICANT BECAUSE WE KNOW THE CLIMATE CHANGE IS A GLOBAL PROBLEM. NOT RELATED TO A SINGLE COUNTRY. SO TO PROTECT THE FUTURE CLIMB AND REDUCE GREENHOUSE GAS EMISSIONS, WE NEED TO HAVE EVERY SINGLE COUNTRY DOING THEIR PART. >> WE HEARD FROM THE SECRETARY SAY THE PRESIDENT IS AVERSIVE A SERIES OF TRUMP POLICIES ON THE ENVIRONMENT, NOT THE LEAST OF WHICH WE MENTIONED. HOW MUCH OF AN IMMEDIATE IMPACT WILL THIS HAVE ON THE BATTLE AGAINST CLIMATE CHANGE? >> IT'S REALLY SIGNIFICANT BECAUSE I DID JUST MENTIONED, PRESIDENT DONALD TRUMP HAD ROLLED BACK NEARLY 100 ENVIRONMENTAL REGULATIONS. TO REQUIRING OIL AND GAS COMPANIES TO REPORT METHANE EMISSIONS WHICH IS A POWERFUL GREENHOUSE GAS. SO WE SAW A HUGE TURNAROUND FROM PRESIDENT BIDEN. IN 2018 COME WE HAD 3% SPIKE IN GREENHOUSE GAS EMISSIONS, OF COURSE, THIS PAST YEAR AND BECAUSE OF COVID-19, THE U.S. IS NOWHERE CLOSE TO MEETING THE AGREEMENT. SO FROM PRESIDENT BIDEN, AND REVERSE BUT PRESIDENT DONALD TRUMP HAD DONE IT IS HUGE TO ALLOWING US TO COVER THE BASELINE SO WE CAN INCREASE AND REALLY START THE WORK THAT IT WILL TAKE TO THE CARBONIZED THE COUNTRY.>> THE FACT THAT THE TRUMP ADMINISTRATION SCOFFED AT CLIMATE CHANGE, HOW MUCH DID THAT PUT THE U.S. BEHIND THE REST OF THE WORLD? >> IT REALLY WAS SIGNIFICANT. WE HAVE TO REDUCE GREENHOUSE GASES BY HALF BY 2030 IF WE HAVE ANY HOPE OF CONTAINING THE GLOBAL TEMPERATURE. SCIENTISTS SAY IT IS NEEDED IF WE NEED TO AVOID THE MOST DANGEROUS EFFECTS OF CLIMATE CHANGE. THEN WE HAVE TO GET TO ZERO EMISSIONS CAN WE HAVE TO COMPLETELY THE CARBONIZED THE GLOBAL ECONOMY BY 2050 TO MEET THE GOALS. WE SAW THE PAST COUPLE YEARS, WHEN THE U.S. DID NOTHING ON CLIMATE CHANGE, AND THAT GOES BACKWARDS AND ALLOWING FOR MORE POLLUTION, FOR MORE EMISSIONS OF CARBON. FOR MORE COAL CONSUMPTION. THAT REALLY HAS SET THE U.S. MUCH FURTHER BEHIND . SOME COUNTRIES HAVE ALREADY MOBILIZED THEIR ECONOMIES AND SET THESE EMISSIONS TARGETS TO MEET ZERO EMISSIONS BY 2050 INCLUDING CHINA, JAPAN, SOUTH KOREA, 120 OTHER GOVERNMENTS HAVE ALREADY MADE THE GOAL. SO FOR PRESIDENT BIDEN TO COME IN AND HAVE THIS AMBITIOUS GOAL IS REALLY HUGE. >> I WANT TO REALLY TALK QUICKLY ABOUT THE KEYSTONE XL PIPELINE THAT THEY ARE STOPPING THE PROJECT. BILLIONS OF DOLLARS HAVE BEEN INVESTED, GOOD MOVE OR BAD MOVE OR DOES IT WORK? >> I THINK IT'S EXCELLENT, IT IS A HUGE WIN FOR INDIGENOUS GROUPS AND ENVIRONMENTALISTS THAT HAVE OPPOSE THIS PIPELINE STRUCTURES, ABOUT 1200 MILES FROM ALBERTA, CANADA. IT EXTRACTS FROM THE TAR SANDS WHICH IS MUCH MORE POLLUTING MUCH MORE DAMAGING TO THE ENVIRONMENT. WE DON'T NEED THAT WELCOME WE HAVE PLENTY OF NATURAL GAS WHICH SPANS THE GLOBE. IT IS A HUGE RISK A HUGE STEP FORWARD AND IT WILL BOLSTER A LOT OF CONFIDENCE OF THE OTHER POLICIES THAT PRESIDENT BIDEN IS PUTTING FORTH ON CLIMATE CHANGE. >> ASSISTANT PROFESSOR AT UNC CHAPEL HILL, THANK YOU FOR YOUR
