Did you know that bears don't hibernate?
At leaast not true hibernation
They sleep longer and more often, but can awaken at the drop of a hat.
A true hibernator lowers many body functions, temperature, heart rate.
many to near freezing.

so all my teachers when i was a youngling lied their faces off to me about bears hibernating? all the books that say bears hibernate, lie?

The problem lies in the Polar Bears that are dependent on ever-shrinking arctic seas ice to alllow them to hunt. Reports of drowned bears and very thin bears are becoming more and more prevalent.

Bee shortage is a bitter problem
Numbers of honeybees, wild bumble bees and other pollinators have declined, raising the risk of plant extinction and threatening the nation's food crops, says a report from the National Research Council. In Utah, the Beehive State, officials made a belated change in pesticide regulations this summer but more needs to be done to protect honeybees, beekeepers say. The nationwide shortage is significant enough that honeybees had to be brought in from Canada and Mexico last year for the first time since 1922, when the Honeybee Act banned imports for fear they would introduce non-native pests, according to the report.
Earth's Wobble Wipes Out Species

Oct. 12, 2006 — Climate change, naturally induced by tiny shifts in Earth's rotational axis and orbit, periodically wipes out species of mammals, a study published on Thursday says.
Paleontologists have long puzzled over fossil records that, remarkably, suggest mammal species tend to last around two and a half million years before becoming extinct.
Climate experts and biologists led by Jan van Dam at the University of Utrecht in the Netherlands, overlaid a picture of species emergence and extinction with changes that occur in Earth's orbit and axis.
The Chandler wobble is a factor considered by satellite navigation systems (especially military systems). It is also claimed to be the cause of major tectonic activity, including earthquakes, volcanism, El Niño, and global warming phenomenon, however there is no actual data which supports such a claim.
During the MWP wine grapes were grown in Europe as far north as southern Britain[4][5][6] although less extensively than they are today[7] (however, factors other than climate strongly influence the commercial success of vineyards, for example wine is made in Alaska today; and the time of greatest extent of medieval vineyards falls outside the MWP). The Vikings took advantage of ice-free seas to colonize Greenland and other outlying lands of the far north. The MWP was followed by the Little Ice Age, a period of cooling that lasted until the 19th century when the current period of global warming began.
In Chesapeake Bay, Maryland, researchers found large temperature excursions during the Medieval Warm Period (about 800–1300) and the Little Ice Age (about 1400–1850), possibly related to changes in the strength of North Atlantic thermohaline circulation.[8] Sediments in Piermont Marsh of the lower Hudson Valley show a dry Medieval Warm period from AD 800–1300.[9]
Prolonged droughts affected many parts of the western United States and especially eastern California and the western Great Basin.[3] Alaska experienced three time intervals of comparable warmth: 1–300, 850–1200, and post-1800 AD. [10]
A radiocarbon-dated box core in the Sargasso Sea shows that sea surface temperature was approximately 1°C cooler than today approximately 400 years ago (the Little Ice Age) and 1700 years ago, and approximately 1°C warmer than today 1000 years ago (the Medieval Warm Period).[11]

The thermohaline circulation (THC) is a term for the global density-driven circulation of the oceans. Derivation is from thermo- for heat and -haline for salt, which together determine the density of sea water. Wind driven surface currents (such as the Gulf Stream) head polewards from the equatorial Atlantic Ocean, cooling all the while and eventually sinking at high latitudes (forming North Atlantic Deep Water). This dense water then flows into the ocean basins. While the bulk of it upwells in the Southern Ocean, the oldest waters (with a transit time of around 1600 years) upwell in the North Pacific (Primeau, 2005). Extensive mixing therefore takes place between the ocean basins, reducing differences between them and making the Earth's ocean a global system. On their journey, the water masses transport both energy (in the form of heat) and matter (solids, dissolved substances and gases) around the globe. As such, the state of the circulation has a large impact on the climate of our planet.

Well..
I can't believe in global warming per say, since as it is right now over the past 100 years the average global temperature has only risen what, a degree if that?
Climate shift however, could cause many of these problems. It wouldn't be the first time, over time our planets climate moves.. where I live was once an ocean, the Sahara was once a rainforest and so was the Out Back. So, I agree the climate is changing.. but I can't see it being connected to Human activity, though if it is our planet will destroy us before we destroy her. Plauges, wars, famine, water shortage. Those are mother natures ways of keeping us in check, yet we do all we can to avoid it, in the end it will all catch up to us.

Message of the Executive Secretary to the Citizens of the World
Meanwhile the findings of a landmark 2005 study into the health of the planet’s ecosystems, called the Millennium Ecosystem Assessment, undertaken by over 1,300 experts from 95 countries, has added its voice to those of the politicians. Two thirds of the services provided by nature to humankind are in decline, worldwide. Humans have made unprecedented changes to ecosystems in recent decades to meet growing demands for food and other ecosystems services.
These changes have weakened nature’s ability to deliver its vital services. Human activity is putting such strain on the natural functions of Earth that the ability of the planet’s ecosystems to sustain future generations can no longer be taken for granted.
This landmark study concludes that to attain the 2010 biodiversity target will require not only fine words, but an unprecedented effort by all sections of society.
