Greenhouse gases, especially carbon dioxide, “correspond to sort of holes” in the light spectrum that would otherwise allow heat to escape, but they block the exits, Mann said.But if there are natural greenhouse gases why do small changes in carbon dioxide levels matter?

Earth’s carbon dioxide levels are about 420 parts per million, compared to 280 before the industrial revolution and the Earth has warmed aboutin that time. Mann suggests another home experiment. Take a clear bowl of water. Put a few drops, say 0.4% of the water, of black ink in it.“And the water turns black now,” Mann said. “Certain chemicals can have a very potent impact in very low concentrations. It’s true of cyanide. That’s why we avoid cyanide in even lower concentrations than that. And the ink experiment really drives how much of an influence a small number of very potent molecules can have... And that’s what’s going on here.”

But there are opportunities to ask for extensions and to go on payment plans.”

Here’s what to know:In addition to tacking on interest and penalties, the IRS can eventually garnish your wages, place a lien on your property, or even place a hold on your passport. But if you file for an extension, or if you file your return with your financial information, you can avoid these consequences. Even if you don’t have the money to pay what you owe in full by April 15, paying just a small part when you file.

across the country are staffed with volunteers who will help you file a return or arrange for an extension for free. These volunteers can help you set up an installment payment plan of as many as 72 months to pay off any owed taxes. Theis also free to use.
