climate of British Columbia. THE COAST REGION
The Coast Region has the abundant rainfall and mild temperatures associated with a maritime climate.

Considerable variation does occur due to the terrain, high mountains and long fiords.

There is also a distinct variation from south to north. Annual precipitation on the West Coast ranges from 130 to 380 centimetres.

The heaviest rain occurs on the windward slopes in the fall and winter months.

The leeward slopes record lowest annual rainfalls.

The range in temperature is smallest on the outer coast due to the maritime effect.

The sheltered inner coasts are somewhat warmer in summer and cooler in winter.

The southwest coast, consisting of the Lower Mainland and the southeast coast of Vancouver Island, has a pleasant climate.

Depending on elevation, some 65 to 130 centimetres of rain falls per year, mostly in the fall and winter.

Victoria averages approximately 75 centimetres of rain a year compared to Vancouver which receives approximately twice as much.

Summer is often a period of relative drought. The area has a long frost-free season and mild winters. THE INTERIOR REGION
The Interior Region, lying east of the coastal mountains and west of the Rockies, has a predominantly continental type of climate.

It is not as rigorous as the Canadian Prairies, except for the northern section.
Considerable variation in climate occurs, especially in winter, as Pacific storms bring relief from cold spells.

The Southwest Interior, lying just east of the high coastal mountains, has the driest and warmest climate of the whole province.

Annual precipitation ranges from less than 25 centimetres to about 50 centimetres in the valleys.

Temperatures in summer may reach 38 degrees Celsius.

The coldest winter months have mean temperatures below zero degrees Celsius.

The Southeast Interior, made up of the Columbia Mountain System and associated valleys, has a more extreme climate than the Southwest Interior.

Although precipitation in the valleys is fairly light, falls on the ridges are heavy.

Mountain passes may receive well over 500 centimetres of snow in a season.

Temperature ranges are typical of a continental climate, from below zero degrees Celsius in the winter to as high as 38 degrees Celsius in the summer.

The Central Interior has a distinct continental climate, with more extreme temperatures and higher precipitation than in the south. Temperature extremes range from 32 degrees Celsius in summer to as low as minus 40 degrees Celsius in winter.

Annual precipitation ranges from 50 to 75 centimetres, while snowfall totals approximately 190 centimetres for the winter season.

The frostfree period is short and unreliable.

The Northern Interior is a vast area and little factual meteorological data are available. Long, cold winters and short, cool summers are characteristic of the area.

Precipitation is lightest in the western sections in the lee of the coastal mountains and heaviest in the foothills and slopes of the Rockies.
THE NORTHEAST REGION
The Northeast Region of the province is a northern extension of the western prairie region of Alberta.

It has a continental climate that is more extreme than the Northern Interior region.
However, it does have long hot summers and a frost-free period long enough to grow grain, forage and other crops.

Indigenous cultures include: Aleuts, who live primarily in coastal southwest Alaska; Inuit, who live on the coast and inland from northwestern Alaska east to Greenland; Athabascans, who live mainly inland in eastern Alaska, the central Yukon, and the Northwest Territories of Canada; the Saami of northern Fennoscandinavia and Native groups in northern Russia.
The Arctic is also a region particularly vulnerable to human-induced climate change.
The marine boundary of the Arctic is formed when the water of the Arctic Ocean, cooled and diluted by melting ice, meets the warmer saltier water of the southern oceans.
This process is known as thermohaline circulation because it is driven in part by temperature and partly by salinity differences. porteau_mp.pdf

This five year review of the 1985 Master Plan for Porteau Cove Provincial Park is submitted for your consideration and approval.
The review has resulted in no substantive changes to either the role of the park or the management of the park's resources.
There is only one key issue to address, the need to expand the land base of the park.
Mammals in the park are mainly comprised of Douglas Squirrel (Tamiasciurus douglasi), Northwestern Chipmunk (Eutamias amoenus) and Racoon (Procyon lotor).
The shoreline of the park is the main outdoor recreation feature.
Porteau Cove's resources contribute significantly to achieving the conservation and recreation goals of the British Columbia Parks System

The elders, who keep thousands of years of history and legend without ever writing it down, have long told children this story: If the ice that freezes thick over the sea each winter breaks up before summer, the entire village could perish.
A group of scientists who spent a year aboard an icebreaker concluded that the year-round sea ice that sustains marine mammals and those who hunt them could vanish altogether in 50 years.
There is currently more carbon dioxide in the atmosphere - the leading cause of global warming - than there has been in at least 500,000 years, Paterson said.
