Apple Unveils Faster New iPhone, Chops Price

June 10, 2008 at 9:54 am · Filed under Technology ·Tagged , ,

SAN FRANCISCO – The iPhone will soon be $200 cheaper and support satellite navigation and faster Internet access, but higher monthly service charges are likely to erase most of the savings.

Apple Inc. revealed Monday that it has scrapped its pricing plan for the iPhone as it unveiled a model that works over faster wireless networks, addressing key criticisms about the device that have hurt the company’s foray into the cell phone industry.

An 8-gigabyte version with the new features will go for $199 when it goes on sale July 11, and a 16 gigabyte model will cost $299, the Cupertino-based company said.

Current iPhone owners who buy a new model and sign up for a new AT&T contract won’t have to pay any penalties to get out of their current contract, AT&T spokesman Michael Coe said. And anyone who bought an iPhone in an AT&T store after May 26 can return it before Aug. 1 for full credit against a new one — less a 10 percent restocking fee.

Obama Hammers McCain, Bush on Economy, Gas Prices

June 10, 2008 at 9:40 am · Filed under Politics ·Tagged , , , ,

RALEIGH, N.C. – Democrat Barack Obama on Monday seized on heightened concerns about the economy, tying John McCain to the Bush administration’s recent record of soaring gasoline prices and slumping employment.
Launching a two-week economics tour in a state the GOP usually considers safe, Obama warned that McCain’s policies on taxes, spending and energy would continue the nation’s slump, which some fear is already a recession. He called for new taxes on oil companies and wealthy individuals, along with $1,000 tax cuts for most working families.

With the presidential general election now fully engaged, McCain pushed back, saying Obama’s bid to end the administration’s tax cuts for upper-income earners would only worsen the economy. He is airing TV ads in key states on the Iraq war, which he sees as a better issue this fall. But he took questions on the economy from donors in Virginia on Monday, and planned a speech Tuesday to small-business owners in Washington.

Global Warming and The Cause

June 10, 2008 at 8:52 am · Filed under Global Warming ·Tagged ,

Global warming is the increase in the average temperature of the Earth’s near-surface air and oceans since the mid-twentieth century, and its projected continuation.

The average global air temperature near the Earth’s surface increased 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the hundred years ending in 2005. The Intergovernmental Panel on Climate Change (IPCC) concludes “most of the observed increase in globally averaged temperatures since the mid-twentieth century is very likely due to the observed increase in anthropogenic (man-made) greenhouse gas concentrations” via an enhanced greenhouse effect. Natural phenomena such as solar variation combined with volcanoes probably had a small warming effect from pre-industrial times to 1950 and a small cooling effect from 1950 onward.

These basic conclusions have been endorsed by at least thirty scientific societies and academies of science, including all of the national academies of science of the major industrialized countries. While individual scientists have voiced disagreement with some findings of the IPCC, the overwhelming majority of scientists working on climate change agree with the IPCC’s main conclusions

Climate model projections summarized by the IPCC indicate that average global surface temperature will likely rise a further 1.1 to 6.4 °C (2.0 to 11.5 °F) during the twenty-first century. This range of values results from the use of differing scenarios of future greenhouse gas emissions as well as models with differing climate sensitivity. Although most studies focus on the period up to 2100, warming and sea level rise are expected to continue for more than a thousand years even if greenhouse gas levels are stabilized. The delay in reaching equilibrium is a result of the large heat capacity of the oceans.

Increasing global temperature will cause sea level to rise, and is expected to increase the intensity of extreme weather events and to change the amount and pattern of precipitation. Other effects of global warming include changes in agricultural yields, trade routes, glacier retreat, species extinctions and increases in the ranges of disease vectors.
