What Would A Heat-Proof City Look Like?

What Would A Heat-Proof City Look Like?

Posted on Friday, 17 August, 2018 by Zheluo Cai

Cities can be miserable during heat waves. All that concrete and asphalt soaks up the sun’s rays, pushing temperatures up even further. Tall buildings can block cooling breezes. Exhaust from cars and air-conditioners just adds to the swelter. This is known as the urban heat island effect: A large city’s built-up environment can make it 2 to 5 degrees Fahrenheit warmer than the surrounding countryside during the day and up to 22 degrees warmer at night. That extra heat is becoming a serious public health problem. On average, 650 Americans die each year from heat-related causes, the Centers for Disease Control and Prevention estimates, and global warming is only expected to make things worse. In recent years, some urban planners have been seeking out creative strategies to combat the heat island effect to provide relief and prevent more people from dying during brutal hot spells. “Cities need to realise that they have the power to change their weather,” said Brian Stone, Jr., a professor at Georgia Tech’s School of City and Regional Planning.

The Ainu, in the historical Japanese texts the Ezo, are an indigenous people of Japan (Hokkaido, and formerly northeastern Honshu) and Russia (Sakhalin, the Kuril Islands, and formerly the Kamchatka Peninsula). On June 6, 2008, the Japanese Diet passed a bipartisan, non-binding resolution calling upon the government to recognize the Ainu people as indigenous to Japan, and urging an end to discrimination against the group. Recent research suggests that the historical Ainu culture originated in a merger of the Okhotsk culture with the Satsumon, one of the ancient archaeological cultures that are considered to have derived from the Jōmon-period cultures of the Japanese archipelago. The Ainu economy was based on farming, as well as on hunting, fishing and gathering.

The Cave Nebula in Hydrogen, Oxygen, and Sulfur.
Image Credit & Copyright: Chuck Ayoub. The featured skyscape is dominated by dusty Sh2-155, the Cave Nebula, a stellar nursery 10 light-years deep. About 2,400 light-years away, the scene lies along the plane of our Milky Way Galaxy, towards the royal northern constellation of Cepheus. Astronomical explorations of the region reveal that it has formed at the boundary of the massive Cepheus B molecular cloud and the hot, young stars of the Cepheus OB 3 association. The bright rim of ionized hydrogen gas is energized by radiation from the hot stars, dominated by the bright star just to the left of the cave entrance. Radiation driven ionization fronts are likely triggering collapsing cores and new star formation within.

The national flag of Nepal is the world's only non-quadrilateral national flag. The flag is a simplified combination of two single pennons, known as a double pennon. Its crimson red is the colour of the rhododendron, Nepal's national flower, while the blue border is the colour of peace. The inclusion of the celestial bodies indicates Nepal's permanence and the hope that Nepal will enjoy the same longevity as the Sun and the Moon. Additionally, the stylized moon represents the calm demeanour and purity of spirit of the Nepali people, while the stylised sun represents their fierce resolve. The current flag was adopted on 16 December 1962, along with the formation of a new constitutional government.

The Last Judgment is a fresco by the Italian Renaissance painter Michelangelo, covering the whole altar wall of the Sistine Chapel in Vatican City. It is a depiction of the Second Coming of Christ and the final and eternal judgment by God of all humanity. There are over 300 figures, with nearly all the males and angels originally shown as nudes; many were later partly covered up by painted draperies. The work took over four years, between 1536 and 1541. Michelangelo began working on it twenty-five years after he finished the Sistine Chapel ceiling, and was nearly 67 at its completion. It was commissioned by Pope Clement VII but was completed under Pope Paul III.
