That we can and that we do are different things. Also, a single volcano like Mt. Saint Helen produced as much "pollutants" in three days as all humans in ten years.

I'm sure you can do better than to stumble along behind Hoyt's fact-challanged leadership?

U.S. GEOLOGICAL SURVEY | Which produces more CO2, volcanic or human activity?

Gas studies at volcanoes worldwide have helped volcanologists tally up a global volcanic CO2 budget in the same way that nations around the globe have cooperated to determine how much CO2 is released by human activity through the burning of fossil fuels. Our studies show that globally, volcanoes on land and under the sea release a total of about 200 million tonnes of CO2 annually.

This seems like a huge amount of CO2, but a visit to the U.S. Department of Energy's Carbon Dioxide Information Analysis Center (CDIAC) website (http://cdiac.ornl.gov/) helps anyone armed with a handheld calculator and a high school chemistry text put the volcanic CO2 tally into perspective. Because while 200 million tonnes of CO2 is large, the global fossil fuel CO2 emissions for 2003 tipped the scales at 26.8 billion tonnes. Thus, not only does volcanic CO2 not dwarf that of human activity, it actually comprises less than 1 percent of that value.

A short time ago (geologically speaking) the question "Which produces more CO2, volcanic or human activity?" would have been answered differently. Volcanoes would have tipped the scale. Now, human presence, activity, and the resultant production of CO2, through the burning of fossil fuels, have all climbed at an ever-increasing rate. On the other hand, looking back through the comparatively short duration of human history, volcanic activity has, with a few notable disturbances, remained relatively steady.

QUARTS | A big fracking deal -- Forget climate change, now we have to worry about fracking earthquakes

The first is that fracking seems to be triggering a lot more quakes. “Significant earthquakes are increasingly occurring within the continental interior of the United States,” wrote the authors of the paper published yesterday in the journal Geology (paywall). “Concurrently, the volume of fluid injected into the subsurface related to the production of unconventional resources continues to rise.” (“Unconventional resources” means gas and oil extracted through fracking.)…

A second implication is that the after-effects can last a long time. Most fracking-related temblors are small and occur within months of when a mixture of water and chemicals are injected at high pressure into wells to break up rock formations that contain natural gas or oil. But in the case of the Oklahoma quake, it took place 18 years after wastewater from oil drilling at Prague began to be pumped into depleted wells for storage in 1993. In November 2011, a 5.0 seismic shock hit the region followed by a 5.7-magnitude temblor and many aftershocks. The quake destroyed 14 homes and was felt 800 miles away…

Imaginary Number: The CO2 emission data does not take into account volcano explosions. Also, it does not measure the largest percentage of volcano emissions which are sulfur compounds and ash.

Not sure why you think so?

Volcanic sulfur particles cause atmospheric cooling, not warming -- which is the opposite effect of what the emitted CO2 causes. On balance, the net effect of volcanic eruptions is global cooling, not warming -- yet global temperatures are now higher than they've been in thousands of years.

Stratospheric sulfur aerosols are sulfur-rich particles which exist in the stratosphere region of the Earth's atmosphere. The layer of the atmosphere in which they exist is known as the Junge layer, or simply the stratospheric aerosol layer. These particles consist of a mixture of sulfuric acid and water. They are created naturally, such as by photochemical decomposition of sulfur-containing gases, e.g. carbonyl sulfide. When present in high levels, e.g. after a strong volcanic eruption such as Mount Pinatubo, they produce a cooling effect, by reflecting sunlight, and by modifying clouds as they fall out of the stratosphere.[1] This cooling may persist for a few years before the particles fall out...

...The effects of the [Mount Pinatubo 1991] eruption were felt worldwide. It ejected roughly 10,000,000,000 tonnes (1.1×1010 short tons) or 10 km3 (2.4 cu mi) of magma, and 20,000,000 tonnes (22,000,000 short tons) SO2, bringing vast quantities of minerals and metals to the surface environment. It injected large amounts of aerosol into the stratosphere – more than any eruption since that of Krakatoa in 1883. Over the following months, the aerosols formed a global layer of sulfuric acid haze. Global temperatures dropped by about 0.5 °C (0.9 °F), and ozone depletion temporarily increased substantially...

Arachnicide.
Not to worry though because there hasn't been any warming since 1998.
This is just more fear-mongering.

Environmental Outlook: Jellyfish And The Health Of The Ocean

National Aquarium ©

Jellyfish have thrived for hundreds of millions of years, but now scientists are worried they’re doing too well. For this month's Environmental Outlook, a look at what warming waters and overfishing mean for jellyfish and the health of the ocean.

Guests:
Lisa-ann Gershwin, author, "Stung! On Jellyfish Blooms and the Future of the Ocean." She is the director of the Australian Stinger Advisory Services.

Bill Dennison, vice-president for science applications and professor, University of Maryland Center for Environmental Sciences.

Jack Cover, general curator, National Aquarium.

Jellyfish are overpopulated due to the appetite for shark fin soup. That is the real environmental abomination.

I agree that the hunting of sharks just for their fins is an abomination, but the killing of sharks is only a small part of the problem of the explosion of jellyfish. From your first link:

What eats jellyfish?

What do jellyfish eat?

There are many kinds, or species, of jellyfish in all the oceans of the earth. The main predator of jellyfish is other jellyfish, usually of a different species.

But jellyfish also have a number of other natural enemies that like to eat them. These predators include tunas, sharks, swordfish and some species of salmon.

Sea turtles also like to eat jellyfish. In fact, each year many sea turtles become ill and even die from eating floating plastic bags and other plastic trash that they mistake for jellies. That is one of the reasons why it is important to keep trash out of the world’s oceans.

So, what do jellyfish eat? Most jellyfish prey on tiny sea creatures called plankton—but some types attack and ingest smaller jellyfish!

Yes, the sea turtles and plastic bags are a bad mix which we have discussed here on previous occasions.

Rising acidity of the oceans works to the jellyfishes benefit. Burning fossil fuel is the reason for this acidification.

Funny how the mercury is crepping back in these new low consumptions light bulb. It seams when we need poison in the name or "green" we don't hesitate.
Mercury was almost extinct, not anymore! Buy low energy bulbs and be marry!
I know the incendecents one were not very good, more heat than light. But they were cheap and without mercury.
And it is in my eye the most beautiful shape ever designed :idea:

Sometimes the questions are complicated and the answers are simple
