    Check out this paper on the predictability of the atmosphere–ocean system that I lead-authored. Thank you for the great summary!

    New paper in J. Clim explores local atmos. predictability forced by SST and vice versa. Clearly demonstrates importance some fundamental issues -- coupled DA, critical role of coupling beyond 5 days, mid-lat. vs. trop. relative predictability/sources.

    Do you hear that etc. - "will not accept advertising or research funded by companies that produce fossil fuels" Please do the same

    Son of a gun, the British Medical Journal launches a campaign for fossil fuel divestment, also announces will no longer accept ads from fossil fuel companies or publish research they fund!!!

    You know what's "radical"? Burning the entire planet down to line the pockets of a few wealthy fossil fuel executives. Dear editorial board: you are still ignorant of the magnitude of the climate crisis. I really struggle to understand why.

    The editorial board’s decision to back not one but two candidates is a significant break with convention, one meant to address the "realist" and "radical" models being presented to voters by the 2020 Democratic field, the editorial says.

    Bolivia's coup administration is so fragile, so illegitimate, that the battled-armed military has to sweep all areas in which dissent could manifest, to safeguard a "democracy" which was installed through bloodshed, in plain sight.

    Huge mobilization of the Bolivian military in the center of La Paz, outside San Francisco cathedral. In six days, social movements will be protesting here against the coup.

    ICYMI: meeting is sponsored in part by Chevron, one of the top expanders of fossil fuel pollution. So has its own conflict of interest. Time for a polluter-free AGU!

    Iran was going to retaliate sooner or later, one way or the other. There was no way they would let this go. But Iran is now trying to make it clear that this is a retaliation for one action, not an escalation into a full-on war. There is no appetite for war in .

    September 2019 U of Maryland poll: Three-quarters of Americans, including a majority of Republicans, say that war with Iran would be unwarranted

    Nightmarish tit-for-tat is upon us. In assessing next move, Trump may be emboldened by inevitable rallying around the flag. But this won't last. Reminder: 75% of Americans didn't think US interests warranted war, even after attack on Saudi oil fields:

    Missiles are flying. This is not a drill. Many can be killed and many will be displaced. We refuse to stand by while this happens and we ask you to join us, , , and many more this Thursday. Find an event near you: .

    War -> Forced Displacement = Refugees & Asylum seekers. Migration is hardly ever a choice. We stand against war in Iran. Not only will a war kill thousands of innocent people, it'll also force many out of their home. Like climate change, war displaces people.

    As a Salvadoran whose country was thrust into US-backed war throughout the 80s, today’s tense reality of a US war with Iran feels oddly familiar. We must demand and resist a warmongering project that will disproportionally destroy the lives of the Third World’s poor.

    Proving that a function is convex is not always easy. Here's a small script that I often use to get numerical evidence that a function is convex before trying to prove it.
