Editorial
Has the Historical Rise in
the Air's CO2
Content Stimulated Tree Growth Over the Past Century?:
An intriguing new study of white spruce trees in Canada provides compelling
evidence that it has.
Medieval Warm Period Records of the Week
This issue's Medieval Warm Period Records of the Week come from
Lake Redon,
Central Pyrenees, Northeast Spain and
Pickerel Lake,
South Dakota, USA. To access the entire Medieval Warm Period Project's

Subject Index Summary
Climate Oscillations
(Millennial Variability - Europe):
What do we learn about 20th-century global warming from studies of the
much-longer climatic history of Europe?
Plant Growth Data
This week we add new results (blue background) of plant growth responses to
atmospheric CO2
enrichment obtained from experiments described in the peer-reviewed
scientific literature for:
American Shoreweed,
Climbing Nightshade,
Creosote Bush,
and a
Wild Radish.
Journal Reviews
The
Real Cause for
Concern About Sea Level:
What is it?
Effects of Global Warming
on El Niņos:
Some climate models are beginning to better represent reality in this
regard.
The Medieval Warm Period
in Western North America:
Was it warmer or cooler than it is today?
Global Warming and Carbon
Sequestration by Boreal Ecosystems:
How does the former affect the latter?
Recovery from Bleaching in
Corals: A new
study reveals a mechanism that greatly boosts success rates.
Temperature Record of the
Week
This issue's
Temperature Record of the
Week is from
Ketchum, ID. During the period of most significant greenhouse gas buildup
over the past century, i.e., 1930 and onward, Ketchum's mean annual
temperature has cooled by 3.45 degrees Fahrenheit. Not much global
warming here!
