«Even in this

According to

Researchers
say global
warming has produced stronger air
currents that allow the birds to spend less time away from their nests, increasing the odds that their chicks will survive.
The unusual changes in
currents may help explain how the larvae of the heat - loving creatures living around hydrothermal vents are dispersed through long stretches of near - freezing waters to reach other
warm havens,
says Adams.
At least half of
current vegetated areas are predicted to shift to a different type of vegetation class, with a general trend of now - present grasses and small shrubs yielding to larger shrubs and trees as the climate
warms, the scientists
said.
The effect is so strong, she
said, that if Earth continues to
warm at the
current rate, the LC50 for one species she has studied, fathead minnows (Pimephales promelas), will be only half as much in 2060 as it is now.
«In this region, the same [storms] that have driven increased snowfall inland have brought
warmer ocean
currents into contact with West Antarctic's ice shelves, resulting in rapid thinning,»
said Thomas.
It's interesting that despite no apparent indication that plants are indeed making a net contribution to the
current trend, we see articles like National Geographic's Plants Exhale Methane, Contribute to
Warming, Study
Says.
Instead, the report
said,
current highs appeared unrivaled since only 1600, the tail end of a temperature rise known as the medieval
warm period.»
«Some feedback loop or other processes that aren't accounted for in these models — the same ones used by the IPCC for
current best estimates of 21st Century
warming — caused a substantial portion of the
warming that occurred during the PETM (Palaeocene - Eocene thermal maximum of 55 million years ago)», oceanographer Gerald Dickens, a professor of Earth science at Rice University and study co-author
said.
Even if the rest of the year were simply average temperature-wise, 2015 would surpass the
current record - holder of 1934 by 0.5 °F, she
said, and with a strong El Niño in place, it's likely that temperatures will stay on the
warmer side for the remainder of the year.
Can you summarize
current state of the world regarding research on expected ENSO behavior in
warming climate, i.e.: a) About the same b) Expect distribution of La Nina / El Nino / Neutrals to change c) Insufficent data to be able to
say much
and therefore to be able to make a stronger statement on how unique the
current and apparently global
warming related ice mass loss is» for Greenland, he
says.
«What's especially concerning about this
current northern fur seal crisis is that this species has a particularly difficult time recovering from unfavorable ocean conditions, such as these
warmer waters,»
says Tenaya Norris, marine scientist at The Marine Mammal Center.
2007 is likely to be the
warmest year on record globally, beating the
current record set in 1998,
say climate - change experts at the Met Office.
«The
warming,» he

currents.
In context of

Also, the idea is to keep
warming below +1.5 ºC even with the
current energy imbalance (
warming in the pipeline) and reductions in aerosols that accompany emissions reductions (though Hansen
says the impact of aerosols from fossil fuels was overstated and other manmade aerosols seem to dominate).
She also stressed that she sees no signs of
current or imminent
warming producing a great destabilization of permafrost in the Arctic: «You can't
say in 20 years it will be 2 degrees
warmer so permafrost will be thawing.
Since a commenter mentioned the medieval vineyards in England, I've been engaged on a quixotic quest to discover the truth about the oft - cited, but seldom thought through, claim that the existence of
said vineyards a thousand years ago implies that a «Medieval
Warm Period «was obviously
warmer than the
current climate (and by implication that human - caused global
warming is not occuring).
That
said, although I believe I understand what he is
saying (and I agree with him regarding the confusion, lost credibility, and inaccuracies that often result when many

warming), I have a few comments about some aspects of his recent post.
It's too soon to
say whether the

Apparently the
current belief (discussed starting on page 18, and like most such statements accompanied by a caveat that much more research is needed) is that the PDO itself is closely linked to global
warming, which is to
say we can expect it to spend a lot more time in the positive phase as global
warming progresses.
Also, if we
say we know what's causing
current warming there's a lot of work to be done explaining model failure on predictions.
One could
say too much extra heat at the earth surface will greatly excite the hurricane safety valve (maybe too much, too often) but not enough heat will be jettisoned to the troposhere and will remain to melt glaciers,
warm air
currents, disrupt preciptation patterns and, in general, muck up the system
[Response: And note that the abstract linked
says «Although the rarity of the
current episode of high average sunspot numbers may indicate that the Sun has contributed to the unusual climate change during the twentieth century, we point out that solar variability is unlikely to have been the dominant cause of the strong
