I like it. Even though this graph is dumbed down a lot and the fact that 2007 and 2012 are compared to the "average" to imply global warming is "getting worse" when really these were anomalously warm years from other factors besides global climate change.

I'm not being picky, I can just see the counter-arguments now and like to prepare for them ahead of time.

No sure if troll or just stupid.

Do you know how hard it is to transmit images from Mars to Earth? That takes electricity, and the higher res image, the more electricity it takes. There has to be a balance between number of images and quality of images taken.

Also, there is an atmosphere on Mars and it contains many of the same gases as that of Earth's, just not much Oxygen and not suitable for human life.

This mission has significant implications on space travel, and is the most advanced space-born robotics mission every successfully completed. Similar techniques could be used to get humans to the surface once a manned mission is implemented.

Since you are posting on a science board, care to use some data or logical reasoning to assert your pig-headed global warming skeptic claim? If not, then gtfo.

On time scales important to us, yes we are. Obviously Milankovitch Cycles and Orbital Forcing is what caused Ice Ages in the past and is what decides the "background state" of temperatures. Humans are perturbations to these natural cycles though, so we really don't know how we will offset them or by how much yet.

I used to be able to bench 225 on flat bench 6 reps. Now, I'd be lucky to put up 145. Don't get me wrong, I love working out and lifting, but damn I can't find the motivation in me right now.

I have read the sticky and read Scooby threads. Not very relevant or interesting to me when I am not currently going to the gym.

Hur dur planning a manned mission to Mars in 2020, finding possible evidence for water/life on Mars, 720p HD imagery and analysis of the surface and composition of rocks on Mars.

How about the feel when you think about how small earth is compared to the 100s of billions of suns in the Milky Way alone? It definitely helps me put my own problems into perspective.

Too bad ice core data has no prior records of human induced climate change so we can only speculate how bad things will get. Top graph is a proxy for temperature. From Vostok, Antarctica ice core, 420,000 years of data.

The Arctic is a great place to study human induced climate change because of it's remote location and relatively negligible local effects of pollution transport. And 1979-present represents about 10% of the time since the Industrial Revolution (1750ish), since we are talking about anthropogenic global warming here.

Also look at this figure of surface global temperature anomalies for the past 30 years, hopefully it can stir up some discussion. Major climate events are coded above the x axis for your reference.

The loss of Arctic sea ice volume…..trend line is -3.0 +/- 1.0 [1000 km***3/decade]…..speaks "volumes" about the accelerating ice volume melt. As of 29 June 2012, the Arctic sea ice volume was the lowest on record (1979-2012) with ~ 2.5 months to go in the annual melt season.

The impact of this accelerating Arctic sea ice volume loss on polar-midlatitude and tropospheric-stratospheric interaction remains to be understood and quantified, but will likely hold a number of interesting scientific surprises, and could represent an example of a nonlinear tipping point in ongoing climate change.

Arctic Sea Ice Volume Anomaly 1979-present...who can explain this graph who doesn't believe in global warming??

Glad to hear you don't believe the science in "The Day After Tomorrow", because it's an extreme exaggeration, even though based on a true phenomenon.

A climate model (HadCM3) have simulated what would happen if the Thermohaline Circulation (THC) came to a stop by imposing the IS92a emissions scenario, which at about 4x the current CO2 by 2050, would essentially shut down the THC, at least temporarily. The Northern Hemisphere would cool on average by 1.7 C in this simulation, with locally much higher changes. (Vellinga, 2008)

True. Parts of interior Antarctica were actually "cooling down" for several years and gaining ice at an impressive rate. The global warming skeptics had fun with this fact, until the ice melted again and everyone who really understood climate knew all along it was just an anomaly and nothing of global significance.

Yes I do. So listen to what I say about climate and most things in general.

I totally agree, no one has a fucking clue how to understand or react to long-term cause and effect things like climate change. Part of the reason scientists know we are so fucked.
