If humans evolved from apes, why are there still apes?

Human Caused Global Warming
How do we know current global warming is human caused, or man made? Is global warming real, or a hoax? Consider the facts: the climate system is indicated to have left the natural cycle path; multiple lines of evidence and studies from different fields all point to the human fingerprint on current climate change; the convergence of these evidence lines include ice mass loss, pattern changes, ocean acidification, plant and species migration, isotopic signature of CO2, changes in atmospheric composition, and many others. The only identifiable cause explaining these changes with confidence is human influence and increased greenhouse gas emissions. Science has simply not found any other cause factor that can account for the scale of the recent increase in radiative forcing and associated warming."

This is important!

"The isotopic signature clearly shows that the extra CO2 in the atmosphere is from fossil fuels."

so a hundred odd PPM of Human CO2 is a lot stronger than the 4000 ppm natural CO2 an ice age existed with?

we've added slightly over 1 molecule in 10,000. That doesn't have a dramatic effect on anything.

ice sheets/glaciers have been melting/retreating since the last glacial maximum 19k years ago, if this ever stops/reverses- then we might have something to worry about. Oceans are alkaline, we are making them infinitesimally less bleach-like

what is it you are most afraid of from global warming?

First there is a carbon signature to our CO2 in the atmosphere.


"Oceans are alkaline, we are making them infinitesimally less bleach-like"

LOL

The oceans are carbon sinks and we have made the oceans 30% more acidic. Which is one reason all the coral reefs are dying.

I can tell you don't actually study this and I am not afraid, your words, I am highly concern as everyone should be. But a collapse of the food chain would be disastrous, but there are lots of other problems already happening.


The average level of carbon dioxide over the past five days is 400.03 parts per million.

For the first time in recorded human history, levels of carbon dioxide in the atmosphere have surpassed 400 parts per million (ppm), according to data released Friday morning from the National Oceanic and Atmospheric Administration (NOAA) from the Mauna Loa Observatory in Hawaii.

The average level of carbon dioxide over the past five days is 400.03 ppm. Carbon dioxide (CO2) is the greenhouse gas that is responsible for 63% of the warming attributable to all greenhouse gases, according to NOAA's Earth System Research Laboratory in Boulder, Colo.

Increasing amounts of carbon dioxide and other gases caused by the burning of the oil, gas and coal that power our world are enhancing the natural "greenhouse effect," causing the planet to warm to levels that climate scientists say can't be linked to natural forces.

Carbon dioxide levels were around 280 ppm prior to the Industrial Revolution, when we first began releasing large amounts into the atmosphere through the burning of fossil fuels.

Carbon dioxide levels were closer to 200 during the Ice Age. There are natural ups and downs of this greenhouse gas, which comes from volcanoes and decomposing plants and animals. But that's not what has driven current levels so high, said NOAA senior scientist Pieter Tans of the Earth System Research Lab. He said the amount should be even higher, but the world's oceans are absorbing quite a bit, keeping it out of the air

"That increase is not a surprise to scientists," Tans said. "The evidence is conclusive that the strong growth of global CO2 emissions from the burning of coal, oil, and natural gas is driving the acceleration."

During the last 800,000 years, CO2 fluctuated between about 180 ppm during ice ages and 280 ppm during interglacial warm periods. Today's rate of increase is more than 100 times faster than the increase that occurred when the last ice age ended.

NOAA: Trends in atmospheric carbon dioxide

The last time that carbon dioxide reached 400 ppm was millions of years ago. How do scientists know this?

Scientists can analyze the gases trapped in ice to reconstruct what climate was like in prehistory, but that record only goes back 800,000 years, according to the Scripps Institute of Oceanography in San Diego. It is harder to estimate carbon dioxide levels before then, but in 2009, one research team reported in the journal Nature Geosciencethat it had found evidence of CO2 levels that ranged from 365 to 415 ppm, roughly 4.5 million years ago.

"They based their finding on the analysis of carbon isotopes present in compounds made by tiny marine phytoplankton preserved in ancient ocean sediments," according to Scripps.

"Crossing the 400 ppm threshold is more than a new data point about greenhouse gas levels in our atmosphere," World Wildlife Fund chief scientist Jon Hoekstra says. "It's a sobering reminder that the planet we know today will not be the planet we know tomorrow."

First time in recorded history????

What is that, like 50 years or so?

The earth has been hear for billions of years.

How many times will you continue to post this blatant lie. I have already discussed this with you and why it isn't counter to climate scientists findings.

"Human Activities Produce More Carbon Dioxide Emissions Than Do Volcanoes"

VANCOUVER, Wash. — On average, human activities put out in just three to five days, the equivalent amount of carbon dioxide that volcanoes produce globally each year. This is one of the messages detailed in a new article "Volcanic Versus Anthropogenic Carbon Dioxide" by Terrance Gerlach of the U.S. Geological Survey appearing in this week's issue of Eos, from the American Geophysical Union.

"The most frequent question that I have gotten (and still get), in my 30 some years as a volcanic gas geochemist from the general public and from geoscientists working in fields outside of volcanology, is 'Do volcanoes emit more CO2 than human activities?' Research findings indicate unequivocally that the answer to this question is "No"—anthropogenic CO2 emissions dwarf global volcanic CO2 emissions," said Gerlach.

Gerlach looked at five published studies of present-day global volcanic CO2 emissions that give a range of results from a minimum of about one tenth of a billion, to a maximum of about half a billion metric tons of CO2 per year. Gerlach used the figure of about one-quarter of a billion metric tons of volcanic CO2 per year to make his comparisons. The published projected anthropogenic CO2 emission rate for 2010 is about 35 billion metric tons per year.

Gerlach's calculations suggest present-day annual anthropogenic CO2 emissions may exceed the CO2 output of one or more supereruptions per year. Supereruptions are extremely rare with recurrence intervals of 100,000-200,000 years; none have occurred historically, the most recent examples being the Toba eruption 74,000 years ago in Indonesia and the Yellowstone caldera eruption in the United States 2 million years ago.

As in all fields of scientific research, there continues to be efforts to improve estimates and reduce uncertainties about how much CO2 is released from the mid-ocean ridges, from volcanic arcs, or from hot spot volcanoes, but agreement exists among volcanic gas scientists about the significantly smaller amount of volcanic CO2 compared to anthropogenic CO2 emissions.

Pope Francis Makes Biblical Case for Addressing Climate Change

 

[Deathbydefault]

It's simple bigotry... They refuse to accept any ideology other than their own. Pathetic. I don't bother wasting air on those that can't even produce a logical and valid argument.

Logical and valid meaning: "[This] is correct because [this] factually proves it." and then provide evidence.
Not, "because God said so".

I actually like a good amount of religious people, being that a large part of my family is Christian. But I hate those of you that refuse to acknowledge anything else other than what you personally believe. I guarantee you that if you can prove to me that God is real in a truthful, factual, independent argument, I will convert to your side. But you can't. I'm 100% sure of that if nothing else.
