Wouldn't the high CO2 concentration over the Amazon jungle be the forest itself and not 'biomass burning'??

Makes you wonder what their "essential" work is if those things aren't.
Those £25K cruises to gawp at penguins they were advertising a few years ago, perhaps? Carbon footprint the size of a medium-size American town.

I note that the Bish has gone on the offensive with the aTTP troll.

Heh, heh.

Harry Passfield -
I write such things to amuse myself. If any others are likewise amused, it's purely coincidence.

New Study: Two Thousand Years of Northern European Summer Temperatures Show a Downward Trend

Amongst other stuff on their website about research on penguins, this is what WWF say "my donation" would help pay for, and the reason why I will not fund WWF because who knows how much goes on the last two items.

How you’re helping penguins
Improving the management of Antarctica’s resources and safeguarding its wildlife
Establishing a network of marine protected areas covering at least 10% of the 20 million square kilometre Southern Ocean
Reducing illegal and unsustainable fishing practices
Raising awareness of the threats of climate change we all face
Your support will also help fund our essential work around the world

Animal and plant populations in extreme environments like the Poles and hot deserts fluctuate wildly. A few good or bad years for them can decimate or hugely multiply the populations. It's the nature of the beast.

The animals and plants that live in these places are only there because they have adapted to this.

Any and all alarmist reports about population changes in these places need to be taken with a glacier of salt.

Thanks HaroldW. Groan to Harry Passfield!
I have copied the article you linked to and paste it here for others' information.
As Harold says, it is not a simple explanation. If penguins need 15% of sea ice cover then perhaps the recent extent of sea ice in the region is problematical - what are WWF going to do about it? Blow warm air over the ice to help melt it? Or, if krill is being eaten by whales etc reducing the amount for penguins, that must prove to be a bit of a conundrum for GP and their anti-whaling stance. Quite what WWF are intending to do to "save" the penguins, I do not know, but will hotfoot it to their website to see if I can find out. As ever, there is never a simple, easy solution, even if there is a problem, which is debatable.

The Adélie penguin population in Antarctica's Ross Sea is booming, with numbers looking to be the highest they've been for 30 years.

While exact results of the latest census of won't be available for two months, current trends indicate that we could have had over a million Adélie penguin pairs breeding in the western Ross Sea over summer.

The population from this area makes up approximately 38% of the entire circum-Antarctic Adélie penguin population.

Research showing Adélie population trends over the past three decades has just been published in the US-based science journal PLOS ONE and is based on the count and ongoing research by Landcare Research scientists Drs Phil Lyver and Mandy Barron, Antarctica New Zealand and Bartonk Solutions.

Dr Lyver said Adélie penguin colonies on Ross Island in the southern Ross Sea are counted every year and had steadily increased at about 6% each year since 2001. He said after declining at about 2% per annum in the 1980s and 1990s the population dropped to its lowest point in 2001 which coincided with the arrival of giant icebergs that altered the local sea ice and environmental conditions in McMurdo Sound.

There had only been sporadic counts of the colonies along the Victoria Land coast, a remote stretch of mainland Antarctica spanning 1000km. Before this summer's survey, the last full census of Victoria Land was back in 2006.

The summer's aerial survey was the first time the entire Ross Sea census had been conducted by helicopter and was made possible with the support of the Italian Antarctic Programme at Terra Nova Bay who provided logistical support for the team.

''A large proportion of the birds along the Victoria Land Coast forage over the deep continental slope ecosystem and often in quite different sea ice conditions to their counterparts on Ross Island to the south, so it is important to understand what is happening with this part of the population, '' Dr Lyver said.

"In an average year, there are around 850,000 pairs of Adelie penguins breeding in the Ross Sea each year. Having the Victoria Land census means we can assess whether the colonies in the northern sector of the Ross Sea have experienced the same level of growth as those in the south", said Dr Lyver.

"If this has occurred, we could expect to get in excess of a million breeding pairs this season. And, our northern-most colony alone, Cape Adare, could have a quarter of those birds."

Adélie penguins are a recognised indicator species, used by scientists and the Antarctic and Southern Oceans management organisation, Convention for the Conservation of Antarctic Marine Living Resources (CCAMLR) to monitor possible changes in the marine ecosystem caused by perturbations such as climate change but also commercial fishing.

The long-term population records provide scientists with an understanding of the natural trends and variation in the Adélie penguin numbers which gives them greater ability to detect possible future changes from human-related influences.

The question now for scientists is what is driving the annual variation and increases they are seeing in the colonies. The high level of synchrony and correlation in annual growth rate amongst colonies suggests a common factor.

Adélie penguins generally do well in areas of intermediate sea-ice concentration – around 15% ice coverage is ideal. The birds need ice for resting but not so much that individuals have only a limited number of cracks close to the colony to forage through, or incur additional energetic costs associated with walking great distances to access open water. However, it's the loss of sea ice in some sectors of Antarctica that is concerning scientists.

Predictions indicate that 75% of Adélie penguin colonies (70% of the breeding population) in Antarctic will decrease or disappear by 2050 owing to climate warming and the disappearance of sea ice. These declines will occur mostly at the colonies north of 70°S. All the Ross Island colonies observed in this study are south of 70°S. Already scientists are seeing declines in Adélie penguin numbers in the West Antarctic Peninsula region where warming, loss of sea-ice and reductions in the abundance of their primary prey, Antarctic krill, has occurred. Significant declines in chinstrap penguins, a species which tend to avoid heavy sea ice conditions, have also occurred in the region suggesting the relationship between sea ice and krill is a major factor influencing penguin numbers.

In contrast to what is happening in the West Antarctic Peninsula, there has been an observed increase in sea extent of sea ice and duration of the sea ice season in the north-western Ross Sea region over the last three decades. This is where many of our penguins spend their time outside their breeding time. The challenge for scientists therefore is to understand the effect that the extra sea ice and other predicted environmental factors such as increasing persistence of polynyas (expanses of water that remain ice free for large part of the year) or snowfall are likely to have on penguin numbers.

It is also possible that the changes we see in the Adelie penguin population are confounded and linked to historical and recent changes in the number of other top-predators (e.g. minke whales and Antarctic toothfish) that compete with penguins for food. The removal of predators that eat krill and/or Antarctic silverfish could result in a greater amount of prey biomass available for penguins, thus supporting larger populations.

These are questions that will be addressed in the next phase of the study, said Dr Lyver.

Yes, TerryS, it's also another example of the BBC allowing the environmentalists to write articles on the business pages.

One of the things Harrabin the 'business analyst' forgot to remind us about was a reduction due to energy-intensive industries shutting up shop. Alcan mothballed the Alcan Lynemouth Aluminium Smelter in 2012, citing energy costs as reasons for closure, even though the plant has been described by some as one of the most efficient in the world.

Germany, where industry still commands a bit more respect and carries some weight, is now starting to back away from the energy insanity regularly promoted at the BBC.

@HaroldW: Re Adelie penguins. Waddya mean "it's likely not a black-and-white issue"? <silly grin>
