  • September – Five from Five

    September – Five from Five

    Five

    Let’s be clear

    • September 2018 and year to date were 4th hottest on record for the globe.
    • The 10 warmest September global land and ocean surface temperatures have occurred since 2003
    • The last five Septembers (2014, 2015, 2016, 2017 and 2018) ranking as the five warmest on record.

    Also worthy of note are the words of an Australian ex-Prime Minister [then opposition leader] when asked about a Carbon Emissions Trading scheme in 2013:

    ”Just ask yourself what an emissions trading scheme is all about. It’s a so-called market in the non-delivery of an invisible substance to no one”

    A visionary clarion call to a generation? I think not.

    I am sure the seminarian and Rhodes Scholar from Oxford would recognise the story of Galileo.

    E si scalda ancora [Apologies to Galileo]

  • Yes. EPIC…

    Yes. EPIC…

    Yes. Genuinely EPIC.

    I learnt about Lagrange Points at school, never imagined I could see what the earth looked like from one of them.

    Is this not truly awe-inspiring?

    On July 20, 2015, NASA released to the world the first image of the sunlit side of Earth captured by the space agency’s EPIC camera on NOAA’s DSCOVR satellite. The camera has now recorded a full year of life on Earth from its orbit at Lagrange point 1, approximately 1 million miles from Earth, where it is balanced between the gravity of our home planet and the sun.

  • That’s deep!

    That’s deep!

    Seven miles deep…

    The project, which was funded by the NOAA’s Office of Ocean Exploration and Research, was designed to establish a baseline for ambient noise in the deepest part of the Pacific Ocean.

    Human-created noise has increased steadily in recent decades and getting these first recordings allows scientists in the future to determine if the noise levels are growing and how this might affect marine animals that use sound to communicate, navigate and feed, such as whales, dolphins and fish.

    Challenger Deep is a valley inside the Mariana trench, seven miles below the surface of the ocean. If Mount Everest was placed inside Challenger Deep, the mountain’s peak would still be a mile underwater.

    That’s deep…

    I am reminded of the work of esteemed American marine biologist, Roger Payne, [producer of the famed Songs of the Humpback Whale] who found in the 1960’s that the great whales of the world ‘enjoyed’ a global communication network for tens of thousand of years, gaining the benefit of a “deep sound channel in the ocean”, a combination of thermal layers and currents that allowed these whales to transmit their ‘songs’ at a wavelength of 20hz over incredible distances to communicate with whales in other oceans.

    Dr. Payne’s work was [and remains] the inspiration for many of the activities of the original Whalesong Foundation [1990]  and WhaleSongServices

  • Reef Bleaching Underway

    NOAA Coral Reef Watch

    NOAA Coral Reef Watch (CRW) has developed a new set of experimental 5-km Regional Virtual Stations (211 total). The Regional Virtual Stations represent a change in the way we have looked at Virtual Station data in the past. They have been designed to take advantage of higher resolution data while simultaneously providing comprehensive and collective information on all reefs in a jurisdiction or predetermined sub-region.

  • Hot September night

    Hot September night

    Apologies to Neil

    Hottest. On record.

    Policy response?

    1. Global average temperature record high for September and January–September;
    2. Separately, global oceans and global land were both highest on record for these periods of time

    Climate Anomalies

    • The September average temperature across global land and ocean surfaces was 1.62°F (0.90°C) above the 20th century average&mdash. This was the highest September temperature on record, surpassing the previous record set last year by +0.12°F (+0.19°C). September’s high temperature was also the greatest rise above average for any month in the 136-year historical record, surpassing the previous record set in both February and March this year by 0.02°F (0.01°C).
    • The September globally-averaged land surface temperature was 2.09°F (1.16°C) above the 20thcentury average. This was also the highest for September in the 1880–2015 record, surpassing the previous record set in 2009 by +0.16°F (+0.09°C). Record warmth was observed across much of South America and parts of Africa, the Middle East, Europe, and Asia.

    Antarctic Sea Ice

    • Antarctic sea ice extent during September 2015 was 100,000 square miles (0.53 percent) below the 1981–2010 average. This was the 16th smallest Antarctic sea ice extent on record and smallest since 2008. The maximum Antarctic sea extent was not reached until the month of October, and will be reported next month.

  • 330 and counting – State of the Climate

    The next time some-one, particularly a Politician, suggests climate anomalies and surface warming is not a [the] critical policy challenge of our time, ask them if they would bet their house or their life on tossing a coin 330 times and getting the same result?

    Land and Ocean Temperatures 2012
    Land & Ocean Temperatures [NOAA]

    The average global temperature across land and oceans during August 2012 was 0.62°C (1.12°F) above the 20th century average of 15.6°C (60.1°F) and ranked as the fourth warmest August since records began in 1880. Monthly global temperatures anomalies have been among the five highest for their respective months for five consecutive months, since April 2012. August 2012 marks the 36th consecutive August and 330th consecutive month with a global temperature above the 20th century average. The last below-average August temperature was August 1976 and the last below-average temperature for any month was February 1985.
