Green the world. Buy an SUV and turn up the heat:
The dangerous rise in greenhouse gases in the atmosphere may be
troubling scientists and world leaders but it could prove to be a boon
for plants, German researchers said Tuesday.
Increasing exposure to carbon dioxide appears to boost crop yields,
Hans-Joachim Weigel of the Johann Heinrich von Thuenen Institute for
rural areas, forestry and fisheries in the central city of Brunswick
told AFP.
"Output increased by about 10 percent for barley, beets and wheat" when
the plants were subjected to higher levels of carbon dioxide, Weigel
said.

Global Land Temperature Warmest On Record In March 2008
ScienceDaily (Apr. 19, 2008) - The average global land temperature last
month
was the warmest on record and ocean surface temperatures were the 13th
warmest.
Combining the land and the ocean temperatures, the overall global
temperature
ranked the second warmest for the month of March. Global temperature
averages
have been recorded since 1880.
An analysis by NOAA's National Climatic Data Center shows that the average
temperature for March in the contiguous United States ranked near average
for
the past 113 years. It was the 63rd warmest March since record-keeping began
in
the United States in 1895.
Global Highlights
The global land surface temperature was the warmest on record for March,
3.3°F
above the 20th century mean of 40.8°F. Temperatures more than 8°F above
average covered much of the Asian continent. Two months after the greatest
January snow cover extent on record on the Eurasian continent, the
unusually
warm temperatures led to rapid snow melt, and March snow cover extent on
the
Eurasian continent was the lowest on record.
The global surface (land and ocean surface) temperature was the second
warmest
on record for March in the 129-year record, 1.28°F above the 20th century
mean
of 54.9°F. The warmest March on record (1.33°F above average) occurred in
2002.
Although the ocean surface average was only the 13th warmest on record, as
the
cooling influence of La Niņa in the tropical Pacific continued, much
warmer
than average conditions across large parts of Eurasia helped push the
global
average to a near record high for March.
Despite above average snowpack levels in the U.S., the total Northern
Hemisphere snow cover extent was the fourth lowest on record for March,
remaining consistent with boreal spring conditions of the past two
decades, in
which warming temperatures have contributed to anomalously low snow cover
extent.
Some weakening of La Niņa, the cold phase of the El Niņo-Southern
Oscillation,
occurred in March, but moderate La Niņa conditions remained across the
tropical Pacific Ocean.
U.S. Temperature Highlights
In the contiguous United States, the average temperature for March was
42°F,
which was 0.4°F below the 20th century mean, ranking it as the 63rd
warmest
March on record, based on preliminary data.
Only Rhode Island, New Mexico and Arizona were warmer than average, while
near-average temperatures occurred in 39 other states. The monthly
temperature
for Alaska was the 17th warmest on record, with an average temperature
3.8°F
above the 1971-2000 mean.
The broad area of near-average temperatures kept the nation's overall
temperature-related residential energy demand for March near average,
based on
NOAA's Residential Energy Demand Temperature Index.
U.S. Precipitation Highlights
Snowpack conditions dropped in many parts of the West in March, but in
general, heavy snowfall during December-February has left the western snow
pack among the healthiest in more than a decade, with most locations near
to
above average.
Nine states from Oklahoma to Vermont were much wetter than average, with
Missouri experiencing its second wettest March on record. Much of the
month's
precipitation fell March 17-20, when an intense storm system moved slowly
from
the southern Plains through the southern Midwest.
Rainfall amounts in a 48-hour period totaled 13.84 inches in Cape
Girardeau,
Mo., and 12.32 inches in Jackson, Mo. The heavy rainfall combined with
previously saturated ground resulted in widespread major flooding of
rivers
and streams from the Missouri Ozarks eastward into southern Indiana.
From March 7-9, eight to 12 inches of snow fell from Louisville, Ky., to
central Ohio. In Columbus, an all-time greatest 24-hour snowfall of 15.5
inches broke the old record of 12.3 inches set on April 4, 1987.
In the Southeast, a powerful tornado moved through downtown Atlanta on
March
14, causing significant damage to many buildings. This was one of 90
tornado
reports from the Southeast in March.
Rainfall in the middle of March improved drought conditions in much of the
Southeast, but moderate-to-extreme drought still remained in more than 59
percent of the region.
In the western U.S., the weather pattern in March bore a greater
resemblance
to a typical La Niņa, with especially dry conditions across Utah, Arizona,
Nevada, and California. March was extremely dry in much of California,
tying
as the driest in 68 years at the Sacramento airport with 0.05 inches, a
2.75
inch departure from average. |
