POPSIs There Global Warming on Other Planets in the Solar System? Martian climate is primarily driven by dust and albedo and there is little empirical evidence that Mars is showing long term warming. Neptune's orbit is 164 years so current brightening is a seasonal response (Neptune's southern hemisphere is heading into summer). Triton's warming is due to the moon approaching an extreme southern summer, a season that occurs every few hundred years. Jupiter's storms are fueled by the planet's own internal heat (the sun's energy is 4% the level of solar energy at Earth). When several storms merge into one large storm (eg - Red Spot Jr), the planet loses its ability to mix heat, causing warming at the equator and cooling at the poles.

POPS “climate change” throughout the entire solar system.
Here are some highlights: Sun: More activity since 1940 than in previous 1150 years, combined Mercury: Unexpected polar ice discovered, along with a surprisingly strong intrinsic magnetic field … for a supposedly “dead” planet Venus: 2500% increase in auroral brightness, and substantive global atmospheric changes in less than 30 years Earth: Substantial and obvious world-wide weather and geophysical changes Mars: “Global Warming,” huge storms, disappearance of polar icecaps Jupiter: Over 200% increase in brightness of surrounding plasma clouds Saturn: Major decrease in equatorial jet stream velocities in only ~20 years, accompanied by surprising surge of X-rays from equator Uranus: “Really big, big changes” in brightness, increased global cloud activity Neptune: 40% increase in atmospheric brightness Pluto: 300% increase in atmospheric pressure, even as Pluto recedes farther from the Sun This Report’s scientific data, from a variety of

POPSNearby Solar System Looks Like Our Own at Time Life Formed Right now, Epsilon Eridani is surrounded by three asteroid rings that scientists believe are held in formation by large planets, the first of which is theorized to sit about half the distance from Mars to Jupiter. In the new paper, two other large planets, slightly farther from their star than Uranus and Neptune are from the sun, are proposed to explain the shape of the outer belts. It will take more sensitive instruments — perhaps like the next-generation of planet-hunting telescopes — to determine whether any would-be Earths lurk inside the habitable zone near the star.

POPSThis Day In History, Happy Birthday America In 1986, more than 250 sailing ships and the United States' biggest fireworks display honored the Statue of Liberty in its 100th birthday year. In 1994, French forces in Rwanda established a security zone for refugees. In 1995, the British Parliament reconfirmed John Majors as prime minister. In 1997, NASA's Pathfinder landed on Mars to become the first U.S. spacecraft to land on the planet in more than two decades. Also in 1997, Mexico's top drug lord died in a Mexico City hospital following plastic surgery to change his appearance.
