In 1999 NASA lost its $125-million Mars Climate Orbiter because spacecraft engineers failed to convert from Imperial to metric measurements when exchanging vital data before the craft was launched. Numbers are important!
Hansen told the politicians that our production of greenhouse gases, principally CO2, N2O, CH4 and CFC, were warming the climate. He said temperatures would go up in the coming years: Continue reading Hansen got it right→
1. Rising: Dispatches from the New American Shore, by Elisabeth Rush
A review by Dave Hage at Star Tribune of Elizabeth Rush’s new book Rising: Dispatches from the New American Shore says it is “a lovely and thoughtful book, so lyrical that you forget how much science it delivers.”
Rush, who teaches creative nonfiction at Brown University, has chosen to examine climate change through the lens of American places and people devastated by rising seas and higher temperatures. Reading her book is like learning ecology at the feet of a poet rather than a scientist.
This assessment involves 84 scientists from more than 40 institutions, and combines data from 24 satellite surveys. It follows in the footsteps of the first IMBIE (Ice Sheet Mass Balance Inter-comparison Exercise) conducted in 2012, and paints a particularly grim picture of the years between then and 2017. Continue reading Antarctic ice loss rates have tripled since 2012→
Last September I half-finished a post on this topic, with a paper by David Spratt and Ian Dunlop as the centre-piece. Their 28-page report on the state of climate science, action and politics entitled What lies beneath? The scientific understatement of climate risks is introduced as a post at Climate Code Red, but I suggest you go directly to the paper itself. Read any part of it, and I can promise you will be alarmed. Continue reading Climate clippings 223→
including $200 million in funding to reduce agricultural pollution and $100 million for “reef restoration and adaptation,” which includes a project to grow stronger corals in laboratories. Other projects include killing off invasive species like the crown-of-thorns starfish and community engagement and enforcement
The 1.5C threshold was set at Paris as an ambitious target because scientists fear that a world warmer than that would be susceptible to ever wilder climactic events that in turn would precipitate greater drought, habitat loss, food insecurity and mass migration.
by combining oxygen loss with ever-worsening ocean warming and acidification, humans are re-creating the conditions that led to the worst-ever extinction, which killed over 90 percent of marine life 252 million years ago.
