Similar negative effects occur with worsening air pollution — higher
levels of ground -
level ozone smog and other pollutants that
increase with warmer temperatures have been directly linked with
increased rates of respiratory and cardiovascular disease — food production and safety — warmer temperatures and varying rainfall patterns mess up staple crop yields and aid the migration and breeding of pests that can devastate crops — flooding — as rising
sea levels make coastal areas and densely - populated river deltas more susceptible to storm surges and flooding that
result from severe weather — and wildfires, which can be ancillary to
increased heat waves and are also responsible for poor air quality (not to mention burning people's homes and crops).
Granted, it is «slow» right now, but the melting has been
increasing quite substantially, and whereas the IPCC had been speaking in the neighborhood of a
sea level increase of 50 cm, figures between one to two meters are becoming common as the

resulting positive feedback, Jim Hansen has suggested that a

So, the positive feedback between melt and velocities implies that more melt leads to higher velocities, which bring in more ice from cold regions to warm regions which
increases the melt and hence the velocity etc, with as a final
result a rapid loss of ice and hence an enhanced
increased sea level.
Granted, it is «slow» right now, but the melting has been

PIG already makes the largest contribution to

If you think about it and if they «are» right about both the causes and the effects (melting ice caps, raising
