something that is supported in warlords of russia and the '80 year winter' earth went through right after the cataclysm.

add to that the fact that the conditions of the great cataclysm were ideal for triggering a new 'little ice age'... and a rather severe one at that.


and if your a beleiver in the who anthropogenic global warming thing (personally i'm not convinced it's entirely anthropogenic, but thats an issue best not gotten into), rifts wouldn't be subject to such factors because the population is far lower, and the advanced civilizations are heavy into clean energy sources like Nuclear. not do you have the same problems of widespread urban zones affecting heat distribution and such that can affect localized climates.

generally, rifts feels like a return to the climate of the early industrial age (1700's or so), which was the tail end of the little ice age. over all the average differenced would only a few degrees cooler, but the seasonal variance would be wider, with bitter cold winters and only slightly less warm summers.

Dinosaurs in Rifts are endothermic.

If nothing else the apperance of Atlantis would have disrupted both huricane formation in the Atlantic (much milder hurricanes and fewer of them) as well as disrupted the gulf stream and Atlantic convayer current, so Europe, especially Northern Europe should average a little colder. Figure 50% fewer hurricanes and on average 1 catagory lower in general. For Northern Europe, figure 5 degrees F lower temperature on average and 2F lower temperature on average in Southern Europe.

That means shorter growing seasons, more snow fall and of course deeper cold in the winter.

Southern US would trend toward slightly warmer and drier. Both as a result of fewer hurricanes and tropical storms, but also the Atlantic conveyer current being disrupted would reduce the heat exchange some, though the temperature increase would be much more modest than the decrease that northern Europe would see. Figure probably only 1-3F on average increase, but some swamps and stuff would dry up from reduced annual rainfall (though not a lot, and some would exapand from the raised sea levels and a large number would become brackish or even salt marshes instead of freash water swamps).

Oh one note, unless the Rifts themselves disrupted atmospheric compostion, the build up of CO2 would not likely have reduced significantly from the end of the 21st century until modern day Rifts. It would have reduced significantly faster than the track we are on (even supposing humanity cleaned up its act) as a result of human civilization being pruned back severly and large swaths of deforested land again having forests covering it (thus trapping a lot of CO2). However, it is unlikely that the full impact of anthropogenic caused global warming would have been fully reversed (even if there was a nuclear or magic/Rift induced "winter" stretching 80 years, the CO2 and a number of other green house gases would still be there to warm things back up again).

Estimates are if we pulled back greenhouse gas production to basically nothing, it would take roughly a millenia for things to completely recover to pre-industrial levels (temperature wise). Of course we could do things to accelerate recovery, such as actively reforesting lands, reducing urban heat islands, etc. Maybe even geoengineering to reflect sunlight for a period of time, etc.

Opening a dimensional portal to a high pressure location/dimension with non-breathable air will flood your current location with non-breathable air. Opening a dimensional portal to a location with no atmosphere at all will cause your atmosphere to flood that location, perhaps pulling you and others through against your will.

According to page 19 WB7, atmospheres of different worlds don't mix.

What is the context of that statement for those of us who don't have Underseas.

It's talking about Dead Pools on the sea floor, which are what the nexus points underwater are called. Basicly anything stepping through a rift that wasn't able to handle the instant change in pressure was killed, and the bodies would tend to pile up in the vicinity of the nexus point.

Edit: Specificly said air & water from different worlds don't mix.

Hmm...Random Rifts just got a whole lot safer...and less interesting.

Curious consequence of that rule is that plasma weapons can't be fired through a rift.

Do rifts prevent any liquid from flowing through or just water?

Atmosphere does not mix through a Rift. We know this in part because if you open a rift to under water, water doesn't come gushing through the Rift.

The only time things "mix" is if a physical solid is pushed through a Rift. Of course then you get in to things like, what if a water elemental tried to pass through...but I'd then argue that Rifts are magical thingies and not thingies of science, so science rules don't apply.

Things can move through Rifts when it makes story sense and not when it doesn't. In general atmospheres (or lack of them) and liquids won't pass through. Otherwise a Rift to open space would eventually vent all of Earth's atmosphere or opening a rift underwater would eventually drain the oceans.

Mutants in Orbit, page 66 wrote:Mars has been a location of dimensional ley line activity on a planetary scale several times in its long history. Now the ley lines again breathe new life into the dead planet. As fate would have it, the old human colony is located at the epicenter of a martian bermuda triangle (one of two). the area within the triangle is subject to influences by other dimensions and distortions in the space-time continuum. this, combined with the terraforming efforts started by the colonists, has spawned a lush tropical rainforest and rolling grasslands that cover thousands of square miles inside the triangle that stretches 430 miles (688km) east and west and to a point 320 miles (512 km) north. these same forces also keep a constant temprature and keep sand storms out of the triangle. there are a dozen other, smaller pockets of vegetation at different locations on the planet, as well. within these areas are clouds, rain, water, and a breathable, earth like atmosphere. If these conditions remain for other a thousand years, they may have long term effects in terraforming the planet.
