Polar regions of Earth also known as Earth’s frigid zones, are the regions of Earth surrounding its geographical poles (the North and South Poles). These regions are dominated by Earth’s polar ice caps, the northern resting on the Arctic Ocean and the southern on the continent of Antarctica. — Wikipedia

  • Iceberg A-68A: hit or miss?
    on November 27, 2020 at 11:22 am

    An enormous iceberg, called A-68A, has made headlines over the past weeks as it drifts towards South Georgia in the Southern Ocean. New images, captured by the Copernicus Sentinel-1 mission, show the berg is rotating and potentially drifting westwards.

    Young Brazilians are increasingly interested in biodiversity, conservation of the Amazon and science as they begin high school, but school students in the North region are more interested in learning about these subjects, and about local fauna and flora, than their peers in the Southeast.

    Humans have a longstanding relationship with the sea that spans nearly 200,000 years. Researchers have long hypothesized that places like coastlines helped people mediate global shifts between glacial and interglacial conditions and the impact that these changes had on local environments and resources needed for their survival. Coastlines were so important to early humans that they may have even provided key routes for the dispersal of people out of Africa and across the world.

    Weather systems responsible for transporting moisture from the tropics to temperate regions in the Southern Hemisphere have been gradually shifting toward the South Pole for the past 40 years, a trend which could lead to increased rates of ice melt in Antarctica, according to new research.

  • A long distance connection: Polar climate affects...
    on November 20, 2020 at 7:00 pm

    The impact of sea surface temperature variations in the tropical Pacific on global climate has long been recognized. For instance, the episodic warming of the tropical Pacific during El Niño events causes melt of sea ice in far-reaching parts of the Southern Ocean via its effect on the global atmospheric circulation. A new study, published this week in the journal Science Advances by an international team, demonstrates that the opposite pathway exists as well.
