Climate Disobedience Center (CDC) is a far-left environmentalist agitation group known for “nonviolent civil disobedience projects,” which include placing false bids for public lands, blocking pipeline construction projects, and closing manual shut off valves carrying Canadian oil into the United States.   
The organization’s founders and current leaders are environmentalist activists Tim DeChristopher, Marla Marcum, and Jay O’Hara.  DeChristopher has served time in custody for federal felonies related to his misrepresenting himself as a bidder for natural resource development rights; he “won” rights valued at $1.8 million for which he could not pay. 
Founded in 2015, the Climate Disobedience Center was formed after the release of Tim DeChristopher from federal prison for defrauding the government when he placed fraudulent bids in a Bureau of Land Management public sale. 
The organization provides trainings, on the ground organizing, coalition building support, faith-based partnerships, written resources on their necessity defense strategy, and legal resources to defend those who participate in their activism. CDC has become notorious in their attempt to utilize the “necessity defense” to excuse their actions claiming that the seriousness of global warming permits to violate federal law, such as by committing fraud or trespassing.   
Lobster Boat Trial
In May 2013, Climate Disobedience Center founder Jay O’Hara and his associate, Ken Ward, prevented 40,000 tons of coal from being delivered to the Brayton Point generating station in Somerset, Massachusetts. The two men were charged with disturbing the peace, failure to act to avoid collision, conspiracy, and negligent operation of a motor vessel. Shortly after charges were filed, District Attorney Samuel Sutter dropped the charges, came out in support of global warming, and joined them at the People’s Climate March in New York City.   
The Climate Disobedience Center states that making this a public trial was their first project as an organization. 
In September 2014, Everett, Washington based activists with the now-defunct Rising Tide Seattle group placed themselves in front of a mile-long train carrying “fracked” crude oil (oil extracted via hydraulic fracturing) from North Dakota to Anacortes. Rising Tide Seattle activists were arrested and charged with trespassing and train related charges. The activists reached out to CDC for legal support which they provided leading to their case being the first in the country to use a “necessity defense” to justify their actions. The jury found the group guilty of trespassing and not guilty of train related charges. Activists remain in the process of trying to appeal their case.  
Enridge Pipeline Shutdown Project
In February 2019, a far-left Catholic environmental group, Four Necessity Valve Turners, illegally turned off the valves of Enbridge Energy oil pipelines transporting oil from Canada into northern Minnesota. In October 2018, activists Emily Johnston and Annette Klapstein were acquitted after shutting down Enridge Lines 4&67 in a multi-state effort which closed off all oil coming from Canada into the United States. CDC provided legal and organizational support for both organizations.  
Climate Disobedience Center is led by the organization’s founders, Tim DeChristopher, Marla Marcum, and Jay O’Hara.
Tim DeChristopher is a far-left environmental activist, ex-felon, and United Methodist pastor. In his final semester at the University of Utah, DeChristopher became involved with other environmental groups attempting to pressure the Bush administration to stop Bureau of Land Management sales leading him to protest the auction. On December 19, 2008, DeChristopher decided to infiltrate the auction and place false bids for land parcels eventually leading to an extreme price inflation causing the auction to be closed. During his prosecution, DeChristopher founded another far-left environmental organization, Peaceful Uprising. In March 2011, after numerous rescheduling and court hearings, DeChristopher was convicted of two federal felonies: one count of false representation and one count of violating the Federal Onshore Oil and Gas Leasing Reform Act and sentenced to two years in federal prison in July of 2011. In April 2013, DeChristopher was released from prison and placed on 3 year probation. He later attended Harvard Divinity School and worked to produce a documentary, Bidder 70, about his experience.   
Marla Marcum is co-founder of Climate Disobedience Center, far-left environmental activist, organizer, and United Methodist pastor. She is also a co-founder of far-left environmental organizations, Better Future Project and 350 Massachusetts. She was a participant in the “Lobster Boat Blockade” action along with CDC. 
Jay O’Hara is co-founder of Climate Disobedience Center and a traveling Quaker minister. Prior to the Climate Disobedience Center, O’Hara was the founder of Climate Summer, an organization of far-left environmentalists biking around New England to promote global warming.  
The Climate Disobedience Center is a project of the Social Good Fund, a 501(c)(3) nonprofit and donor-advised fund provider.  As such, CDC does not file annual reports with the IRS.
