STUDY: Climate Change Poised to Reawaken Ancient Weather Pattern

Global warming is approaching a tipping point during this century that could reawaken an ancient climate pattern similar to El Niño in the Indian Ocean, according to a study published in Science Advances by scientists at the University of Hawaiʻi at Mānoa, the University of Arizona and the University of Texas at Austin.

If that tipping point comes to pass, floods, storms and drought are likely to worsen and become more regular, disproportionately affecting populations most vulnerable to climate change in the region.

The study presented computer simulations of climate change during the second half of the century which showed that global warming could disturb the Indian Ocean’s surface temperatures, causing them to rise and fall each year much more steeply than they do today. The seesaw pattern is strikingly similar to El Niño, a climate phenomenon that occurs in the Pacific Ocean and affects weather globally.

“Although paleo evidence suggested that this Indian Ocean El Niño occurred during the last glacial time under much colder conditions than today’s climate, climate models simulate its reawakening under much warmer climate owing to favorable changes of atmospheric and oceanic circulations in the Indian Ocean” said Fei Fei Jin, co-author and professor of Atmospheric Sciences at the School of Ocean and Earth Science and Technology (SOEST).

According to the research, if current global warming trends continue, an Indian Ocean El Niño could emerge as early as 2050. 

Today, the Indian Ocean experiences very slight year-to-year climate swings because the prevailing winds blow gently from west to east, keeping ocean conditions stable. According to the simulations, global warming could reverse the direction of these winds, destabilizing the ocean and tipping the climate into swings of warming and cooling akin to the El Niño and La Niña climate phenomena in the Pacific Ocean.

The result is new climate extremes across the region, including disruption of the monsoons over East Africa and Asia. A break in the monsoons would be a significant concern for populations dependent on the regular annual rains to grow their food and sustain their economies.

Carbon Dioxide in Atmosphere DID NOT Break 400 Parts Per Million Last Week!

Carbon dioxide measurements in the Earth’s atmosphere did not top 400 parts per million as reported by the National Oceanic Atmospheric Administration.

“On May 9, the daily mean concentration of carbon dioxide in the atmosphere of Mauna Loa, Hawaii, surpassed 400 parts per million (ppm) for the first time since measurements began in 1958. Independent measurements made by both NOAA and the Scripps Institution of Oceanography have been approaching this level during the past week. It marks an important milestone because Mauna Loa, as the oldest continuous carbon dioxide (CO2) measurement station in the world, is the primary global benchmark site for monitoring the increase of this potent heat-trapping gas….

This is simply not true.  Here is the revised data and you can see that on May 9th it did not go over 400 PPM:

Climate Refugees in the South Pacific

100,000 people still live on the 32 atolls that make up the south Pacific island nation of Kiribati,but global warming is causing sea levels to rise. The archipelago, which lies halfway between Australia and Hawaii, lies just two meters above sea level and is considered especially endangered.

The first two atolls have already been submerged.

Kiribati’s president is faced with a dilemma: does he have to evacuate all the country’s residents?

Living Dangerously… Beach Erosion or Global Warming?

I just noticed this youtube clip that was posted by youtube user puuikibeach, however he doesn’t identify the beach other then what he says below:

I sure wouldn’t ever purchase that house that is at the end of the video that’s for sure.  I would say this house is going to be toast with the rising sea levels and a good storm.

Your Family’s Greenhouse Gas Emissions Calculated… Dave Smith: Cow Fart Expert

You can use this online calculator to get a rough “ballpark” estimate of your personal or family’s greenhouse gas emissions and explore the impact of taking various actions to reduce your emissions.

And news from India which reader Dave Smith pointed out earlier in a comment:  Actually, farting would be a much more accurate headline. Many researchers believe that cow and even termite flatulence make up a major portion of greenhouse gases.”

Cows With Gas: India’s Contribution to Global Warming:

…By burping, belching and excreting copious amounts of methane – a greenhouse gas that traps 20 times more heat than carbon dioxide – India’s livestock of roughly 485 million (including sheep and goats) contribute more to global warming than the vehicles they obstruct. With new research suggesting that emission of methane by Indian livestock is higher than previously estimated, scientists are furiously working at designing diets to help bovines and other ruminants eat better, stay more energetic and secrete lesser amounts of the offensive gas…
