But Obama faces a reality that many of these groups seem slow to recognize: While the 20th - century toolkit preferred by traditional environmentalists — litigation, regulation and legislation — remains vital to limiting domestic pollution risks such as the oil gusher, it is a bad fit for addressing the building human influence on the climate system, which is driven now mainly by a surge in emissions mostly outside United States borders in countries aiming to propel their climb out of poverty on the same fossil fuels that generated much of our affluence.

Realclimate, which was launched largely defensively in 2004 (you can read an explanatory note in, you guessed it, the East Anglia e-mails) has matured into a valuable resource for anyone trying to gauge what science has, and has not, revealed about a human influence on the climate system.

For months, the stasist blogosphere has been aflame with «Gates of various kinds — attempts to spin one or two errors or overstatements on particular issues, along with various comments in the East Anglia e-mail messages, into the unraveling of the many lines of science pointing to a rising, and risky, human influence on the climate system.

But I wouldn't look for fresh findings there to up - end the basic picture of a growing human influence on the climate system.

For a long time there's been a strong perception among those of us tracking research on human - caused global warming that meteorologists are more apt to doubt that humans could dangerously disrupt climate than the much smaller community of climatologists studying the overall climate system and what influences its patterns.

The science pointing to a rising human influence on the climate system is simply delineating the boundaries of the problem — and they are still very fuzzy boundaries on many important points (the extent of warming and pace of sea level rise, just for starters).

What's refreshing is that the building human influence on the climate system is not being portrayed definitively as an unfolding catastrophe, with present - day events cast as the reason for action.

When you look behind dueling posts and columns, it's clear that the building and long - lasting influence of humans on the climate system is progressively tipping the odds toward outcomes that can be bad for agriculture in many struggling places.

Trenberth argues that since science / physics has already established the human influence on climate, oceans, etc. (and Curry would not say otherwise) it makes more sense for Curry to have to show that there is no influence on water vapor and precipitation (i.e., intensification of storm activity / heavy precipitation) than to show that there is, because of basic physics / physical systems / physical relationships that constitute the global climate cycle.

On the question of hurricanes, the theoretical arguments that more energy and water vapor in the atmosphere should lead to stronger storms are really sound (after all, storm intensity increases going from pole toward equator), but determining precisely how human influences (so including GHGs [greenhouse gases] and aerosols, and land cover change) should be changing hurricanes in a system where there are natural external (solar and volcanoes) and internal (e.g., ENSO, NAO [El Nino - Southern Oscillation, North Atlantic Oscillation]-RRB- influences is quite problematic — our climate models are just not good enough yet to carry out the types of sensitivity tests that have been done using limited area hurricane models run for relatively short times.

Overall, I think we're on the slow path toward integrating into our consciousness that humans are, and will remain for generations, a rising influence on the global environment and the climate system.

Since the climate system is highly variable on its own, that smallness sets a very high bar for confidently projecting the consequences of human influences.
