In this 2015 talk, David Reay from the University of Edinburgh talks about Nitrogen and Red Tides, and explains how it inspired Alfred Hitchcock's 1963 The Birds film. Watch his entire lecture on Nitrogen and Climate Change

Blame Hitchcock's Crazed Birds on Toxic Algae

In the summer of 1961 hundreds of birds attacked the town of Capitolo, CA. Most of the birds were sooty shearwaters, a normally non-aggressive species that rarely comes to shore. Alfred Hitchcock was a regular visitor to nearby Santa Cruz and read about this episode. He went on to direct a film—The Birds—based on the idea of hundreds of birds attacking humans. The reason for this attack remained unknown for over 25 years until it was discovered that the birds had been affected by domoic acid, a toxin produced by red algae.,_California#Birds

Esteemed Short-Lived Climate Pollutant (SLCP) experts, Drew Shindell (Duke University & Science Advisory Panel Chair) and Klimont Zbigniew (IIASA), present the newest knowledge on SLCP emissions, sectors, and mitigation opportunities. From the perspective of what we've learned since the publication of the 2011 UNEP & WMO Integrated Assessment of Black Carbon and Tropospheric Ozone, the experts explore trends and opportunities for enhancing mitigation of black carbon, methane, and HFCs. Watch the full 36 minutes long presentation, featuring additionally black carbon and HFCs.

A new study led by scientists at the University of Bristol has warned that unless we mitigate current levels of carbon dioxide emissions, Western Europe and New Zealand could revert to the hot tropical climate of the early Paleogene period – 56-48 million years ago.

The planet was still hungover from the astonishing disappearance of its marquee superstars, the dinosaurs. Earth’s newest crater was still a smoldering system of hydrothermal vents, roiling under the Gulf of Mexico.

Michael Mann Responds to ‘Uninhabitable Earth’

Paul Ross from / talks with climate scientist Mike Mann about the ongoing heat wave, and elaborates on security implications.

Several specific conditions are feeding the Carr fire. Afternoon temperatures have peaked in the triple digits around Redding, Calif., since early last week. On Wednesday, the high was 107 degrees. At the same time, winds that were persistent but manageable earlier in the day picked up, gusting to 21 mph. The dew point — a measure of how much moisture is in the air — dropped precipitously through Thursday afternoon until humidity was 10 percent as the temperature reached 110 degrees.

On top of that, the soil in Northern California is exceptionally dry. A hotter-than-average summer and a very dry winter have led to tinder-dry vegetation. When it ends Tuesday, this month will become Redding’s hottest July on record, with an average temperature of 86.7 degrees. The energy release component, or how much fuel is available for the fire, is at the highest it has been around Redding since at least 1979.
