Global Warming. Here's the thing.

Because we know from direct measurements for the past 880,000 years, and proxies prior to that what the CO2 and CH4 levels were. You could try to look at scientific journals put out by Scientific Societies like the Geological Society of America and the American Geophysical Union. But, of course, you have to have a scientific vocabulary exceeding that of a third grader to read and understand the articles. Sorry about that.
Past CO2 levels were effectively proxies for temperature. That correlation is now broken. You can't correlate CO2 with temperature anymore.

What part of we are still below the peak temperature of previous interglacials do you not understand?

Again, nothing happens without a cause. What do you believe is pushing our temperatures up?

The same exact things that led to temperatures rising from a glacial cycle to an interglacial cycle that have happened 33 times since the transition to an icehouse planet. You act like it's never happened before but it's happened 33 times in the last 2.7 million years. We live in an icehouse world where the poles have different thresholds for extensive continental glaciation. This leads to increase climate fluctuation environmental uncertainty.

You aren't answering the question. Again, what do you believe is causing the Earth's temperatures to rise? "The same as before" doesn't cut it.

Lots of things. The natural variability of earth's climate. Increased climate fluctuation environmental uncertainty is an artifact of a bipolar glaciation world where the threshold for extensive continental glaciation is different at each pole.

Willie Soon, at the Center for Environmental Research and Earth Sciences (CERES), who also has been researching sun/climate relationships at the Harvard-Smithsonian Center for Astrophysics (U.S.A.) since 1991: “We know that the Sun is the primary source of energy for the Earth’s atmosphere. So, it always was an obvious potential contributor to recent climate change. My own research over the last 31 years into the behavior of stars that are similar to our Sun, shows that solar variability is the norm, not the exception. For this reason, the Sun’s role in recent climate change should never have been as systematically undermined as it was by the IPCC’s reports. Hopefully, this systematic review of the many unresolved and ongoing challenges and complexities of Sun/climate relationships can help the scientific community return to a more comprehensive and realistic approach to understanding climate change.”
 
Richard C. Willson, Principal Investigator in charge of NASA’s ACRIM series of Sun-monitoring Total Solar Irradiance satellite experiments (U.S.A.):
“Contrary to the findings of the IPCC, scientific observations in recent decades have demonstrated that there is no ‘climate change crisis’. The concept that’s devolved into the failed CO2 anthropogenic global warming (CAGW) hypothesis is based on the flawed predictions of imprecise 1980’s vintage global circulation models that have failed to match observational data both since and prior to their fabrication. The Earth’s climate is determined primarily by the radiation it receives from the Sun. The amount of solar radiation the Earth receives has natural variabilities caused by both variations in the intrinsic amount of radiation emitted by the Sun and by variations in the Earth-Sun geometry caused by planetary rotational and orbital variations. Together these natural variations cause the Total Solar Irradiance (TSI) at the Earth to vary cyclically on a number of known periodicities that are synchronized with known past climatic changes.”
 
Hong Yan (晏宏), Professor of Geology and Paleoclimatology at the Institute of Earth Environment and Vice Director of the State Key Laboratory of Loess and Quaternary Geology in Xi’an, China: “Paleoclimate evidence has long been informing us of the large natural variations of local, regional and hemispheric climate on decadal, multidecadal to centennial timescales. This paper will be a great scientific guide on how we can study the broad topic of natural climatic changes from the unique perspective of external forcings by the Sun’s multi-scale and multi-wavelength impacts and responses.”
 
Jesus Kee-rist you are stupid. Saying "the climate is variable" doesn't tell us what is making it rise. Saying "many factors affect the climate" isn't telling us what is making it rise. The primary factor making it rise is an increasing level of greenhouse gases in the atmosphere, primarily CO2.

We are in an intergacial period. The earth has been warming for 22,000 years.
 
First, stop sucking. Secondly, if 98% of scientists say that human caused global warming is a fact, I would tend to believe them rather than people like you. I may not have done the tests, but I've seen plenty of the results.
Really? What results have you seen? Use your own words. I don't need a link. I need to hear you put it into your own words so I know you understand what you are talking about. Can you do that?
 
How much less?

Did you know that our emissions have been declining for almost two decades?

Did you know that our emissions could go to zero overnight and the rest of the world would replace it in five years.

So... Why doesn't it matter?

Nonsense blah blah blah. Also, when most of the life on the planet starts going extinct in about 20 years, you will think it matters than. And if you are planning to live past 2050, you will definitely think it matters then. Because you'll be dead.

Yes, that's all you blabbering is nonsense. Sheesh, you leftist anti science cultists are stupid.
 
It's not world history it's the history of earth's climate. Even the IPCC agrees that it's important to understand past climates. Are you disagreeing with the IPCC?

Yes, it is important to understand past climates. To get a good understanding of just how seriously we are quickly destroying our planet. I found a little something about what may be the worst extinction event in world history. You should find it interesting.

Bipolar glaciation does affect the earth's climate. It's been driving earth's climate for 3 million years.

Recently ice sheets have been thinning and disappearing. Where they have disappeared, the earth absorbs sunlight instead of reflecting it back into space. That increases the rate of global warming. I watched a show a while ago taking about Inuit peoples to the north of Canada needing to get their whole villages moved. Because ice has disappeared from their shores. Leaving their villages exposed to the wrath of the sea.
