Is global warming a threat to the human species?

Question

Is global warming a threat to the human species?

Answer 1

No.  People who want the UN or any other government to force us to destroy ourselves so that they can control every aspect of our lives, are a threat to the human species.  You people who believe this tripe, and willingly ignore the actual science, are a bunch of lemmings who are willing to let someone else control your life. So sad.

Answer 2

People aren't going to all die because of GW.   We might lose a couple billion people when food and water gets in short supply.    Crops aren't going to grow so well when the pollinating animals die off from environmental stresses like too much heat or too much/not enough rain....    We will have to deal with tropical and sub tropical diseases in places they aren't in now.    Life will most likely be different than it is now, but we won't completely dissappear as a species.

Answer 3

Yes it is global warming is very harmful to all it causes the ozone layer to melt which then cause the teputure to rise after that the  ice in the tundras of the world will melt which will lead to the ocean riseing which could cause floods

Answer 4

Rising sea levels, starvation due to lack of crop and competition for, not to mention the return of deadly dormant viruses! I think it's safe to say yes it is

Answer 5

Dear God, I certainly hope so. Human beings are not a successful species, and do not deserve this Earth.

Answer 6

If the oil continue to take all their money out of the market , it will not be long till we don't have any.

Answer 7

Global Warming is no more of a threat to the Human species as to any other species.

There are many credible Scientist saying that the warming that has occurred is within the normal cycle of warming and cooling . there was a report of one place where a glacier had retreated and man made artifacts were found indicating that there had been people living there in the past before the glacier covered it

The claim that it is man made has turned out to be the most comprehensive ,most successful Global marketing campaign in history. Think of all the new products that have been developed or old products repackaged as green and sold at higher prices to combat "Global Warming".

Big Business is has jumped on the bandwagon and will do whatever they can to prolong the Hype.

Answer 8

No.

It's a threat to peoples' pocket books though.

Answer 9

It depends where you live, your back yard may turn into a desert or a lake front property.

Answer 10

Absolutely not!

The only threat to the human species IS the human species!

(And George W. Bush)

I'm not quite willing to classify him as human!

Answer 11

We are our own worst enemy and the enemy of all species, certainly.  However, AGW threatens our lifestyle more than ourselves at present.  It is really that, more than us as a species that is the problem.  Humans coexisted with other species quite nicely for tens of thousands of years.  It's only been in the last 1-300 that we have become a problem for our planet.  There is a saying among medical doctors that "All pathology is fundamentally self limiting".  I would like to believe that what's ahead is a series of events that would lead to the collapse of technology and the society based on it.  If that came before warming reached a fatal and irreversible level we would survive, with a population of a few hundred thousand, and the earth would heal from that point on.  It isn't a pretty picture, but much better than any of the alternative scenarios.

Answer 12

No, it has happened before. The Roman warm period and the Medieval Warm period were both times of prosperity. It's the cold periods that were a threat.

Answer 13

No, but global cooling sure will suck.

Answer 14

Global warming is a joke.

Answer 15

Nope.

Optimum world wide temps. are 11 degrees above todays.

Answer 16

It's not clear how species extinctions will affect the ecosystems that we rely on, in turn threatening our species.

A careful examination of a large number of species in numerous parts of the planet projects that a stunning portion of them will be "committed to extinction" in just 50 years, with only modest global warming (Thomas, 2004). "Committed to extinction" means that, in the language of poet Pedro Pietri (1968?), "their names [are] listed in the telephone directory of destruction," that is, the book of death. It does not mean that 50 years from now all these "committed" species will be gone, but rather that they will no longer have a habitat in which they can survive. The demise of the last members of such species may hang on for some decades, but their ultimate doom is assured.

The findings are the result of a comprehensive examination of more than a thousand terrestrial species -- plants, insects, mammals, birds, frogs and reptiles -- in regions representing about 20% of the Earth's surface. The regions studied are located in all continents except Asia, and represent a wide variety of environments: boreal (northern), temperate, and tropical forests, tundra, grasslands, savannah, deserts. The amount of warming that was projected in the study was shockingly small. Three projections were used: 0.8 to 1.7 °C (1.4 to 3.0°F) in the minimal warming case, 1.8 to 2.0°C (3.2 to 3.6°F) with mid-range climate change, over 2.0°C (3.6°F) at maximum (Thomas, 2004; Pounds and Puschendorf, 2004).

But with only this rather minimal amount of warming, and even with an assumed ability to disperse to more favorable environments, 11, 19, and 33 percent of total species (in minimal, mid-range, and maximal cases, respectively) will disappear. Mortality among those species with little or no ability to disperse will be considerably higher (34, 45, and 58 % in the respective no dispersal cases). Moreover, the "minimal" case (0.8 to 1.7 °C/1.4 to 3.0°F) represents the minimum expected warming by 2050: as the study's authors point out, this means that this level of extinction is inevitable (Thomas, 2004). In 50 years, more than 10% of terrestrial species -- at minimum -- will be on a one-way path to extinction; in 100 years, almost all those species will be gone.

"Contrary to previous projections," the authors note, "[climate warming] (which they attribute to human activity) is likely to be the greatest threat in many if not most regions." The study did not examine the "historically unprecedented" carbon dioxide levels with which organisms will have to contend, or interactions between climate change and other ecological threats, which the authors indicate are likely to be even more severe than climate change in isolation (Thomas, 2004). The message of this study is simple: climate change kills -- and kills extraordinary numbers of living things -- even when it is minor.

The article above also outlines how moderate global warming can lead to methane release and abrupt, catastrophic global warming, as happened in the Permian-Triassic extinction, wiping out the vast majority of species on the planet.  So much for the people who find it reassuring that "natural warming happened in the past."

Answer 17

yes, because if the temperature rises1 to 2 degrees there will be no ice in the Attic ocean. But if the temperature rise 2 to 3 degrees the amazon  will turn into a desert.But if the temperature rises 5 to 6 degrees major cities (new york, San Diego, Miami etc) will be flooded under water.

Answer 18

duh!

Answer 19

Yes because if this was real, global warming would be a punishment to human's ignorance and  stupity. humans are lazy, wasteful, lying, cheating, war starter, and plain stupid.
