June 2010 Was Hottest on Record
What is it so special?
NOAA has released their global temperature data for June 2010 confirming that the month was the warmest on record, judged by combined global and ocean surface temperature.
Beijing hits a near-record 105 degrees Fahrenheit. Boston, New York City, and Philadelphia break 100 degrees and set new daily highs. Meanwhile, in Baghdad and Riyadh, on July 6 it was 113 and 111 degrees, warmer than average but still cooler than in Kuwait, which set the day’s world temperature high at 122 degrees….
Yes, we’re suffering a global heat wave. No, it’s not the apocalypse. But it may be a further sign of climate change.
“You can’t say any one heat wave is caused by global warming. But you can say that what global warming does is it makes events just like this more likely,” says Anthony Leiserowitz, director of the Yale Project on Climate Change.
Arctic Sea Ice Loss Confirmed As Main Cause of Faster Polar Warming
It’s long been known that melting Arctic ice could help speed global warming. As the ice melts, surface reflectivity changes, more heat is absorbed than reflected, more warming.
Using the most recent observational data from the European Centre for Medium-Range Weather Forecasting, Screen and co-author Ian Simmonds uncovered a nearly perfect season-by-season match during the 20-year period analysed between surface warming trends and reductions in sea ice cover.
The findings show that the main driver of so-called “polar amplification” — warming in excess of the global average — is shrinking ice cover, and not increased cloudiness or changes in ocean and atmospheric circulation, as others have argued.
Since 1989, the Arctic has warmed over 2°C, compared to a global average of 0.5°C.

Here is the best argument against global warming:
. . . .
Oh, right. There isn’t one.
There is no good argument against global warming. In all the brouhaha about tiny errors recently found in the massive IPCC report, the posturing by global climate deniers, including some elected officials, leaked emails, and media reports, here is one fact that seems to have been overlooked:
Those who deny that humans are causing unprecedented climate change have never, ever produced an alternative scientific argument that comes close to explaining the evidence we see around the world that the climate is changing.
根据路透社新闻指出，澳洲的科学家们在3月15日（周一）发表了一份“气候状态”（State of the Climate）的报告证实气候变迁却有其事。
- 自1960年开始，澳洲大陆的平均温度上升了摄氏0.7度，有些局部地区甚至上升了摄氏1.5 到2度。
- 从1870年到2007年，全球平均海平面上升了将近200mm (8英寸)，在20世纪海平面平均每年上升了1.7mm；而从1993-2009，却是大约每年3mm！
- 科学家们说，在2009年全球二氧化碳含量为百万份之386(ppm)，高于过去800,000年，甚至2千万年前存在于大气的百万分之170－300 ppm
Australia’s top scientists on Monday released a “State of the Climate” report at a time of growing skepticism over climate change
“We are seeing significant evidence of a changing climate. We are warming in every part of the country during every season and as each decade goes by, the records are being broken,” said Megan Clark, head of Australia’s state-backed Commonwealth Scientific & Industrial Research Organization (CSIRO).
Here’s the meat of their report, according to Reuters:
- Since 1960, the mean temperature in Australia has increased by about 0.7 degrees Celsius, but some areas of the country had warmed by 1.5 to 2 degrees Celsius in the past 50 years, the report said.
- Australia’s warmest decade on record is 2000 to 2009.
- While total rainfall in Australia had been relatively stable, the geographic distribution changed significantly over the past 50 years, with rainfall decreasing in southwest and southeast Australia, the major population areas.
- Sea levels around the island continent since 1993 have risen 7-10mm per year in the north and west and 1.5 to 3mm in the south and east, said the report.
- From 1870 to 2007, the global average sea level rose by close to 200mm (8 inches), sea levels rose at an average of 1.7mm a year in the 20th century and about 3mm per year from 1993-2009, it said.
- Sea surface temperatures around Australia have increased by about 0.4 degrees Celsius in the past 50 years.
- The scientists said global carbon dioxide concentration in 2009 of 386 parts per million (ppm) was much higher than the natural range of 170 to 300 ppm that existed in the atmosphere for the past 800,000 years and possibly 20 million years.
- The scientists said that based on their monitoring of the nation’s climate for 100 years, Australian average temperatures are projected to rise by 0.6 to 1.5 degrees Celsius by 2030.
