Classic polar bear prank, akin to a snipe hunt. “Look, son. If you even think you see one, go for it, because OMG LOOK THERE’S ONE RIGHT NOW!”

It will take years to clean up the national and global messes created and promulgated by his predecessor and the Democrat Party. May his decisions be wise, the results productive, and may we become a more prosperous nation for all. God Bless America.
… Scientists suggest that the greater contribution to skyrocketing methane levels has more to do with biological sources of the gas. Methane molecules are made of carbon and hydrogen atoms, and the carbon in biological methane tends to be slightly lighter than the carbon in methane associated with fossil fuels. And over the past decade or so, the proportion of lighter methane in the atmosphere compared to heavier methane has been rising. “I think this perspective is basically right,” said Martin Helmann, of the Max Planck Institute for Biogeochemistry, in Jena, Germany, in an email. Helmann was not involved in the research.
The authors of the Science paper have some ideas about why biological sources of methane may be increasing. “In the southern hemisphere especially,” Nisbet said, “but also in the northern tropics, a series of really wet years has caused wetlands to expand”—and vegetation decomposing in swamps and shallow lakes is a well known source of natural methane emissions. Another is cows, which generate methane as they digest their food, then belch it out into the air.
These explanations, however, aren’t at all definitive — another key point Nisbet and his co-authors make in the Science paper. “The measurements we make in the air are direct,” he said. “Estimates of where methane is coming from, by contrast, is much less reliable. You estimate the contributions from gas leaks, count up the cows, estimate the emissions from wetlands. There’s obviously going to be a lot of error.”
And in fact, there is: the estimates of how much methane should be going into the atmosphere are greater than what actually ends up there. Tracking methane emissions more accurately is crucial, said the scientists, and not just as an academic exercise.
“If we want to control greenhouse-gas emissions,” Nisbet said, “it’s obviously important to know where the emissions are coming from.”
Global vegetation decomposition, wetlands, the oceans, rice paddys, rain forests, patio hibachis, your neighbor’s annoying little yapping kikmi dog and Humpback whales are all part of the mix.

I hate this “Earth Day” garbage. Nature has been trying to kill us off for millennia and has never back-pedaled the threat. Not once. And not once has the Earth given us the common courtesy to thank us for ignoring that undeniable fact.
So in response to “Earth Day,” we turned on all our lights, cranked up the furnace, cranked down the air conditioning, turned on the humidifier and dehumidifier at the same time, and left the refrigerator door open. I plugged in the electric weed-whacker, taped the trigger, watched it dance around the back yard and dig a trench into a fresh gopher run. Judging from the color of the dirt, it actually caught one of the little furry bastards.
We washed our socks one at a time in the Kenmore with the load setting on “full.” We flushed twice to make sure a silverfish was gone forever, and we made sure that the lawn sprinklers watered the sidewalk properly.
We also burned a lot of fossil fuel by taking numerous unnecessary trips to our next-door neighbors’ house for inane chit-chat and let the car idle in their driveway for hours until the Sears DieHard was simply glowing with happy amused electricity. We even left the TV on all night and turned the TiVo on to watch it for us.
And Gaia snickered.
