The new technique, which avoids some of the pitfalls of previous methods, showed that Antarctic ocean temperatures jumped about 14 degrees Fahrenheit during the first of the two warming events, likely the result of massive amounts of heat-trapping carbon dioxide gas released from India's Deccan Traps volcanic region. The second warming spike was smaller and occurred about 150,000 years later, around the time of the Chicxulub impact in the Yucatan.

A new reconstruction of Antarctic ocean temperatures around the time the dinosaurs disappeared 66 million years ago supports the idea that one of the planet's biggest mass extinctions was due to the combined effects of volcanic eruptions and an asteroid impact.Both events were accompanied by warming episodes the U-M-led team found by analyzing the chemical composition of fossil shells using a recently developed technique called the carbonate clumped isotope paleothermometer.

Producers must now also grapple with the looming question of demand. OPEC warned in its most recent report that global demand for its product is fragile, despite low prices. Some of its major customers are suffering from slower economic growth, and the removal of fuel subsidies in oil producing countries may also be hurting. In addition, mild weather in the Northern Hemisphere was discouraging buyersExceedingly well-preserved bird fossil specimens dating 50 million years represent a new species that is a previously unknown relative of the modern-day ostrich, according to a new paper co-authored by Sterling Nesbitt of

Analysts say that for prices to truly recover, a production cut -- not a freeze -- would be required, an eventuality that now seems extremely unlikely.
A further recovery in oil prices would surely require outright cuts in global supply and increases in demand, which suggests that the next big move up will not take place until next year when the market should be much closer to balance," said Capital EconomicsHenry, an award-winning journalist, is one of the most prominent journalists on Fox News.

Each option has advantages and disadvantages. Knowing you'll receive a check each month for the rest of your life even if stocks are being mauled by a severe bear market can engender a sense of well-being and financial security that research shows can lead to a more satisfying and happier retirement. But if you have few retirement resources beyond that pension income
Taking the lump sum, on the other hand, gives you a lot more flexibility in spending and meeting unexpected outlays (or indulging in the occasional splurge)more years can also be a daunting task that you shouldn't take lightly, especially given today's miserly yields and the low rates of investment returns that many investment pros believe we'll see in the future
So how can you sift through these pros and cons to come up with an arrangement that works best for your particular situation.
As you're going over your expenditures, try to separate essential expenses, such as housing costs, taxes, food and health care, from discretionary ones such as travel, entertainment and eating out. This will give you a much better sense of how much wiggle room you have to pare back expenses should you need to in the futureNext, consider the income you'll have to cover your expenses, starting with Social Security. If you're not already receiving Social Security payments, you can find out how much you're likely to qualify for at different ages by going to Social Security's Retirement Estimator
