Ireland – Cork suffered flooding today as the combination of heavy rainfall and high tides caused tidal damage in some low lying areas. The city remains on orange alert for flooding with a further high spring tide at 8pm this evening. Cork is expected to receive up to 70mm of rainfall in a 24 hour period up to 10pm this evening.

Global Warming

Global warming changing Earth’s wobble

Melting ice sheets – especially in Greenland – are changing the distribution of weight on Earth. And that has caused both the North Pole and the wobble, which is called polar motion, to change course, according to a study published Friday in the journal Science Advances.

Scientists and navigators have been accurately measuring the true pole and polar motion since 1899 and for almost the entire 20th century they migrated a bit toward Canada. But that has changed with this century and now it’s moving toward England, said study lead author Surendra Adhikari at NASA’s Jet Propulsion Lab.

While scientists say the shift is harmless, it is meaningful. it highlights how real and profoundly large an impact humans are having on the planet.

Since 2003, Greenland has lost on average more than 600 trillion pounds of ice a year and that affects the way the Earth wobbles in a manner similar to a figure skater lifting one leg while spinning. On top of that, West Antarctica loses 275 trillion pounds of ice and East Antarctica gains about 165 trillion pounds of ice yearly.

These factors all combine to pull polar motion toward the east, Adhikari said.

Wildfires

Wildfires – Mexico

Wildfires have engulfed forests in the mountains of Tepoztlan, a town not far from Mexico’s capital. The fires started sometime on Tuesday, apparently as the result of farmers burning weeds to prepare the area for planting. The Mexican government has mobilized the army, police, conservation teams, and helicopters to battle the fire in hard to reach mountain areas.
