No More Cages: New Animal Cracker Packaging Sets The Mighty Beasts Free

Yes, we will reach that level, using the worst-case, least likely scenario. Population cannot continue to rise exponentially. Hence, the most likely value is around 600 ppm, provides no significant mitigation occurs. Personsally, I do not believe this will continue, as future generations are likely to take greater action.
No noticeable effects have been observed at concentrations below 1%, except for a slightly increase respiratory rate.
Relative to 600 ppm, at 1,000 ppm CO2, moderate and statistically significant decrements occurred in six of nine scales of decision-making performance. At 2,500 ppm, large and statistically significant reductions occurred in seven scales of decision-making performance (raw score ratios, 0.06–0.56), but performance on the focused activity scale increased.
The recommended desirability of increasing the allowable limits for daily exposure to carbon dioxide is based upon the recognition that work in any unusual atmospheric environment requires normal health and the absence of active medical conditions which would be exaggerated by the work and the environment. By appropriate selection of normal individuals fo work in atmospheres containing CO2, effects can be expected to be minimal and acceptable.
Finally, there are also tidal variations in rotation rate and polar motion caused by the near-equilibrium long-period tides, which have periods from about 9 days to 18.6 years. For rotation rate, the dominant contributor is in fact the solid-earth tides."
I think I have asked this question before but ......what are the dark brown streaks on the ice that appear on the small calved piece but continue along the glacier? Is this till, dirt and rocks that have been ground from the surface of Greenland?
This is going to sound weird.
I pick up litter.
A few months ago, I got a litter stick from Amazon. I put a few trash bags in my pocket, put on gloves, and went out into my neighborhood and got started.
The neighborhood was frankly trashed; most places in my city are these days. Decline of services and all. I can't do this most days, because my health is pretty poor, so it took me a while to finish my first pass. Now, every few weeks I can clean up my neighborhood in a couple of trips.
I fully realize that this makes me the crazy old guy in a hat and gloves on the side of the road, looking vaguely homeless. I don't care.
There are kids in this neighborhood. There are churches. People walk along these sidewalks every day. And now they don't have to think about what a dump the neighborhood is. They don't have to worry about walking around broken glass. They get to think about other things, hopefully better things.
It's changed my relationship with my neighborhood. I know it better. I know people here now; I've got regular stops on my route where they've invited me to use their trash cans. I've had some fun conversations.
And this might be my ego talking, but I think I see more people in the park lately.
Whether this is all coming to an end or not, there are people all around you. They're no less important than they've ever been. I'd argue they're more important than ever. Some of them need your help.
The only happiness I've found is in service to others.
Our triple isotope dataset of CH 4 from the sediment and water of the shallow ESAS reveals the presence of CH 4 of microbial origin formed on old carbon with unexpectedly low stable carbon ( δ 13 C as low as − 108 ‰) and hydrogen ( δ D as low as − 350 ‰) isotope signatures down to about 50 m under the seabed in the thawed permafrost. These data demonstrate that at locations where a thick marine clay layer is present, this CH 4 is partially oxidized before reaching the seawater. However, at locations where ebullition was observed from the seabed, no oxidation was identified in the stable isotope surface sediment profile. In that case, and considering the very shallow water column ( < 10 m) in this area, this microbial gas will likely reach the atmosphere when sea ice is absent. Our results show that thawing subsea permafrost of the ESAS emits CH 4 with an isotopic signature that cannot be easily distinguished from Arctic wetland emissions when looking only at stable isotope data. This similarity might complicate recent efforts to quantify Arctic CH 4 source strengths on the basis of isotopicand back-trajectory analysis of atmospheric CH 4 . Further in situ work is necessary – specifically on the isotopic composition of CH 4 in gas bubbles that reach the atmosphere – to better quantify the contribution of the ESAS to the global methane budget.
Randy,
The majority of the scientists and engineers do not have the skills to be concise, on target and quick on come backs. It is unfortunate...
Polar cod fulfil a key role in the Arctic food web, as they are a major source of food for seals, whales and seabirds alike. But the polar cod themselves might soon be the hungry ones. Under the ice of the central Arctic, the juvenile fish are indirectly but heavily dependent on ice algae. As a result, retreating sea ice could have far-reaching impacts on the food web.
I think it'll be a while before we get to levels that effect us directly.

More than 1,000ppm before complaints of drowsiness.
What effects will the surface concentration have on living things? High levels have been shown to make trees more susceptible to insects and disease, but what about other plant life and ocean life?

Pan, who works on atmospheric chemistry at the National Center for Atmospheric Research in Boulder, Colo., found that as thunderheads rise to heights up to 50,000 feet above the Earth’s surface, they cause ripples in the boundary between the troposphere—the lowest layer of the atmosphere—and the stratosphere—the next layer above it. Those ripples can actually tear a gap in the boundary layer on the front of the storm, allowing ozone-rich stratospheric air to pour down to the troposphere.
The effect is more marked in warmer weather, and is not explained by increases in grass pollen, total pollen or fungal spore counts, nor by an interaction between these and rainfall. There was an independent, positive association between ozone concentrations and asthma admissions.
The pinging noise is reported by locals to have reverberated around Fury and Hecla Strait in a remote part of northern Canada.
The Canadian military has investigated a mysterious pinging sound coming from the sea floor in a remote region of the Arctic, officials have told the BBC.
The strange noise is reported by local people to have frightened animals away over the past few months.
Crucially, the study also established that the infection started in thawed, contaminated soil, rather than emanating directly from decades-old poisoned reindeer carcasses or even human remains in graveyards, as was earlier believed.
This, in turn, means that controlling new outbreaks in a warming climate is virtually impossible, other than by mass vaccinations of people and animals.
