EDITOR’S NOTE: This story is part of an ongoing series answering some of the most fundamental questions around climate change, the science behind it, the effects of a warming planet and how the world is addressing it.Even though carbon dioxide is light and invisible, the amount put in the air by the world’s nations through the burning of coal, oil and gas and the making of cement adds up to massive numbers. Since 1959, the world has spewed 1.55 trillion tons (1.41 trillion metric tons) of carbon dioxide, according to, a group of scientists who track emissions and publish in peer review scientific journals.

In 2020, the last year for full national data, China spewed more than 11.7 billion tons of carbon dioxide (more than 10.6 billion metric tons), which is 30.6% of the globe’s carbon dioxide emissions and more than twice as much carbon pollution as the United States which was the next highest emitter at 13.5%, scientists calculated. The European Union, when lumped together, comes in third at 7.5% followed by India’s 7%.But scientists say just looking at last year’s emissions doesn’t really show who caused the problem. That’s because carbon dioxide stays in the atmosphere for

or longer. So historic emissions matter.

Looking at emissions from countries from 1959 through 2020, the furthest Global Carbon Project goes back and beyond which some data gets less reliable, the United States, not China, is the biggest carbon polluter and it isn’t that close.NEWARK, N.J. (AP) — New Jersey Transit and its train engineers were moving closer to a potential strike as early as next week, but both sides will first head to Washington to meet with a federal mediation board in hopes of averting a rail shutdown.

The National Mediation Board ordered both sides to show up on Monday in an attempt to work out their differences, both sides said Friday.A strike could happen in just a week on May 16, crippling commuters across the state.

New Jersey Transit operates buses and rail in the state, providing nearly 1 million weekday trips, including into New York City. The agency plans to increase bus service if there is a rail strike, but the buses won’t be able to handle close to the same number of passengers.The Brotherhood of Locomotive Engineers and Trainmen in mid-April overwhelmingly rejected
