Mars Is Coming Out Of An Ice Age (reuters.com)
Taco Cowboy quotes a report from Reuters: An analysis of radar images that peered inside the polar ice caps of Mars shows that Earth's neighbor is coming out of an ice age that is part of an ongoing cycle of climate change, scientists said on Thursday. Using images taken by satellites orbiting Mars, the researchers determined that about 20,872 cubic miles (87,000 cubic km) of ice has accumulated at its poles since the end of the ice age, mostly in the northern polar cap. Scientists are keenly interested in piecing together the climate history of Mars, which contains strong evidence that oceans and lakes once pooled on its surface, bolstering the prospects for life. From the perspective of an Earthling, every day on Mars may feel like an ice age. According to NASA, temperatures on Mars may hit a high at noon at the equator in the summer of roughly 70 degrees Fahrenheit (20 degrees Celsius), or a low of about minus-225 degrees Fahrenheit (minus-153 degrees Celsius) at the poles. The Martian ice began its retreat about 370,000 years ago, marking the end of the last ice age, according to the research published in the journal Science
Not many people tbh. 26% is above the level where spontanious fires can occur. You think forest fires in todays 21% is bad? You REALLY wouldn't want to go for a walk in the woods in summer if it was 26%. Not only that , high O2 levels = hugh insects and arthropods.
I did some looking into the effects of solar changes on global and solar-system temperatures, because I wondered how much of an effect it might have, if any.
I know most people are already fans of a certain "team" when it comes to global warming / climate change, so they are more interested in bulstering their original guess than learning more information, but those those who are curious here's what I found out. Temperatures on the other planets have, on average, risen less than on earth, but they have risen some. It's hard to be certain, but a reasonable estimate is that changes in the sun might account for 25%-35% of the warming we've seen on earth.
Digging through all the propaganda and distorted data on AGW is difficult, but there seems to be pretty good evidence to support the notion that 25%-35% is caused by increased CO2, caused both by fossil fuel use and deforestation. Deforestation also increases average daily high temperatures more directly by reducing evaporative cooling during the hottest part of the day (and corresponding rain).
That leaves about 40%-50% of the increase that can't be clearly attributed to any specific cause. Objective research by people not funded by political entities would be helpful.
