Researchers found that due to warming waters, the edge of the sharks» range could shift as much as 40 miles poleward per decade, pushing the sharks away from the warming oceans near the equator into different habitats.

Despite large year - to - year variability of temperature, decadal averages reveal isotherms (lines of a given average temperature) moving poleward at a typical rate of the order of 100 km / decade in the past three decades [101], although the range shifts for specific species follow more complex patterns [102].

Other aspects of global warming's broad footprint on the world's ecosystems include changes in the abundance of more than 80 percent of the thousands of species included in population studies; major poleward shifts in living ranges as warm regions become hot, and cold regions become warmer; major increases (in the south) and decreases (in the north) of the abundance of plankton, which forms the critical base of the ocean's food chain; the transformation of previously innocuous insect species like the Aspen leaf miner into pests that have damaged millions of acres of forest; and an increase in the range and abundance of human pathogens like the cholera - causing bacteria Vibrio, the mosquito - borne dengue virus, and the ticks that carry Lyme disease - causing bacteria.

Landmark studies included Parmesan (1996), finding a latitude shift attributed to climate change in a North American butterfly (Edith's Checkerspot, photo (c) 2004 Jeffrey Pippen, by permission), and Parmesan et al. (1999) with «the first large - scale evidence of poleward shifts in entire species» ranges» from Europe.

For example, one of the clearest predicted ecological impacts of climate is a poleward shift in the ranges of plant and animal species.

And as would be expected, the poleward range of southerly marine organisms has ebbed and flowed accordingly.

Once you prove that to 95 % that species ranges are retreating poleward, they ask for proof about specific species.

In 1982, HH Lamb wrote about how the ranges of birds and fishes had moved poleward in the first half of the 20thC.

A wide range of other observations (such as reduced Arctic sea ice extent and increased ocean heat content) and indications from the natural world (such as poleward shifts of temperature - sensitive species of fish, mammals, insects, etc.) together provide incontrovertible evidence of planetary - scale warming.

So you need to look at a wide range of indicators all of which have independent sources of error (for instance, errors in satellites are not likely to be correlated with errors in weather stations or ocean buoys) and see if your understanding matches all of the different aspects that you expect from the theory (stratospheric cooling, ocean warming, Arctic melt, poleward and upward expansion of biomes etc...).

Recent meta - analyses indicate that on average, examined terrestrial species have been moving poleward about 1.76 km / yr (reported as 17.6 + 2.9 km / decade), apparently keeping pace with regional temperature change, although species range shifts to higher elevations have on average lagged behind climate (Chen et al., 2011).

In some cases, extensive gene flow or assisted migration from populations in warmer parts of the range may enhance the genetic potential for rapid evolutionary response of poleward populations (e.g., Kuparinen et al., 2010).

Northern - latitude countries and high - altitude regions may become increasingly important for biodiversity and species conservation as the ranges of species distributions move poleward and upward in response to climate change (Berry et al., 2006).
