Climate Definition and 189 Threads

There is a lot of debate going on in the media and on forums like these as to whether or not anthropogenic global warming is real. Here is a link to an article in the AAAS Science Magazine that states there is no disagreement between climate scientists as to the consensus, not majority or...

They were delayed by weather. (get it?) :smile: http://news.yahoo.com/s/nm/20060428/ts_nm/space_satellites_dc" Off topic, here's an informative piece of journalism from the same article: Idiots.

I have been wondering about climate classifications. Based on average annual temperature and precip, a large chunk of the southeast/southcentral United States is lumped into the Humid Subtropical climate zone. But that seems misleading to people with agriculture or gardening interests, since...

Adding fuel to the fire ( :wink: :biggrin: ) of controversy and debate over Global Warming, http://www.npr.org/templates/story/story.php?storyId=5293273 'Weather Makers' - http://www.theweathermakers.com/ Flannery mentions that the 'energy budget' in the atmosphere, which contributes to...

I won't say who said it, but does this sound right to you? Dendrochronolgists on TV all say it so easy, you count the tree rings and the space in between, and that will tell you about the temperature and precipitation and how long the tree lived. Also: This sounds kind of dumb, but what about...

Let's do another one. The idea that humans can and have had a big impact on climate is increasingly thriving. Apparently we are the central factor -Anthropocentrism. It started with Ruddiman who had produced a http://courses.eas.uAlberta.ca/eas457/Ruddiman2003.pdf . How come, well the...

The Earth periodically cools and warms on a large time scale. What causes this fluctuation?

I got this great idea. It came to me. Instead of Anthropogenic global warming (AGW), we should call it catastrophic anthropogenic climate alternation (CACA). :cool: Do we like this one better or should we stick with AGW? I personally like CACA better. Maybe I'll use it instead. :biggrin: Reminds...

Is there any evidence for a climate change around this time ? i hope to link a change in climate with the fall of the Mycenaean civilisation, a date for any climate change would solidify other historical data. thanks.

Summary for Intellectuals It’s a dedicated duty for mankind to preserve the habitability of the Earth for future generations. Earth- and environmental scienctists are the observers and analysts for policymakers to decide the best course of action. But the mysteries of Earth are exceptional...

MK asked on another thread how a particular frog ties into climate change. I responded and provided a general connection between types of plant communities and the carbon they can "sink" from the atmosphere, and allusions to how loss of habitat in general is contributing to despeciation (in this...

Did a catastrophic change in the climate bring about the dark ages? In the year 535-536 Byzantine historian Procopius recorded, "the sun gave forth light without brightness". Tree ring analysis show abnormally little growth in irish oak in 536 and another sharp drop in 542...

I need to read through this a few more times before I really "get it" but it will be of general interest. After one read-through, it looks like the effects of methane on climate have been underestimated in the past because this gas was measured in the atmosphere after it has mixed with other...

One of the changes that appears to be occurring in the North American climate, involves greater snow pack in the winters at high elevation, and warmer temperatures at low elevation. This could have two important effects. 1) Animals that are migratory may find that environmental cues from...

The insatiable greed for profit is leading to who knows what disasters. While everyone focuses on the latest bout of terrorism (which is a reaction to a cycle of acts of terrorism that are bound to increase), this is what the scientists are saying: The following statement calling for the...

I became curious about Beringia's climate. Beringia is located between Chukotka and Alaska, neither of which are commonly considered tropical paradises. But Beringia existred during, and because of, the Ice Age, which suggests that it should have been far colder than Alaska. Perhaps incredibly...

Why mongoloid people have slanted eyes or blacks big lips etc.Is that the adaptation to the climate ?

I'm not sure if this is correct spot for analysing the logic in the climate change discussion. But it's about logic and not about global warming. So we give it a shot. Let's meet Stephen Schneider I will not comment here, that would be risking poisoning the well. Only notice that SS is a...

If someday we discover how to mine metals from the core, will it have any effect on the magnetic field or the climate of the Earth due to reduction of heat in the core as the metal mined will be hot and will slowly drain the heat of the core.

I am looking to learn about the major flaws with our current theories and data on climate change, particularly in terms of the ice ages. Any examples of inconsistencies or problems with data, or any other information you could give me would be much appreciated. Thanks, Matt.

I guess I just beat Ivan by posting this. The abstract is http://www.nature.com/cgi-taf/DynaPage.taf?file=/nature/journal/v432/n7015/abs/432290a_fs.html. Sounds like water is boiling at o degrees Celsius. Some background on urban heat island effect. (All not true anymore?!)...

We have been fighting the last few days about the enormous impact of minute changes in a minute factor, carbon dioxide. We think that CO2 is causing significant more (triple to five times more) Greenhouse gas effect changes than it's fair share. We base this on the ice cores, the apparent...

In 1998, the Mars Climate Orbiter probe crashed into the surface of Mars, instead of entering orbit. The resulting inquiry revealed that NASA navigators had been making minor course corrections in SI units, whereas the software written by the probe's makers implicitly used British units. The...

Although we see threads starting supporting Green House Gas global warming, we tend to overlook the publications that counter them. Here is one from May (almost overlooked): and some remarks in the conclusion: Translation: there is a high correlation between global temperatures and...

The current understanding of palaeo climate is fundamental for the current views on climate mechanism. One important part in that is using the stable isotope ratios, mainly of 18O and 2H or deuterium. We have registered those in the ice cores of Greenland and Artarctica as well as in the oceanic...

I need every help I can get! I need to know all about the layers in the atmosphere and the function and structure of ozon including cimate issues. To be more specific about the layers, I need to know what they consist of, where they have their names from and why, temperature and what...
