Other news
The atmosphere's CO2 levels briefly topped 400 parts per million (ppm) --another ominous milestone in the climate crisis -- at an observatory in Hawaii this week. But, alas, that doesn't stop a vocal minority of deniers who've come up with a long list of talking points.

Copernicus also had skeptics -- who persisted for decades after his death --who didn't believe his argument that the sun, not the earth, was the center of the universe. (In 2013, Copernicus' birthday was celebrated with a Google doodle).

We're also continuing the fight to confirm Gina McCarthy as EPA administrator: Learn more at www.standwithgina.com.

"It's a natural cycle," "there's no scientific consensus," and "it's a conspiracy" are a few common arguments heavily used by organizations with a stake in dirty fossil fuels.  So we know you'll find good use for these 99 climate-denier rebuttals -- whether you submit a comment to your morning newspaper or drop a line at your next neighborhood cookout.  From Think Progress

Some good news
How many ways can you say it? Environment + economy are not mutually exclusive (it's right in our PennFuture mission). A new report by the Office of Management and Budget (OMB) makes clear: over the last decade, EPA regulations imposed about $45 billion in costs, but created $640 billion in benefits.

Fun stuff
What would Jules Verne think? A plane has begun a historic around-the-world trip one section at a time. Why is this news? The plane -- Solar Impulse -- is a prototype that flies on solar cells and lithium batteries. From Treehugger

To do
Join PennFuture in Pittsburgh for NWF's Google hangout with renowned climate guru and scientist Dr. Michael Mann. We'll have pizza and snacks as we discuss climate science followed by a Q&A session with Dr. Mann. What's a Google hangout, you ask? It's a virtual meeting -- You can participate right in our Pittsburgh office on Monday, May 13, 5:30 to 6:30 p.m. Not in Pittsburgh? You can still participate online from your computer or smartphone.
