This rise will largely offset reductions in water requirements from higher CO that plants will need. Therefore, it is expected that our water requirements may not necessarily rise due to higher temperatures, because those needs will be offset by higher CO. However, evaporation from ponds, irrigation reservoirs, glaciers — evaporation that occurs not from plants but from free-water surfaces — will be greatly accelerated, and that is an important point o ...[+++]f which we need to be aware.

Deep-sea fishing with bottom trawls (i.e. gear designed to catch species on or near the bottom of the sea) below 800 metres from the water surface is banned.

(Return tabled) Question No. 152 Ms. Kirsty Duncan: With respect to the development of unconventional gas resources, including shale, tight and coal bed methane, and its possible impacts on the environment: (a) what, if any, research has the government undertaken regarding the development of unconventional gas resources, (i) what was the scope of this research in the areas of, but not limited to, air quality, aquatic and terrestrial ecosystem impacts, economic impacts, occupational risks, public safety concerns, and seismic risks, (ii ...[+++]) what, if any, resources did the government provide for this research, (iii) what, if any, process was established to ensure the independence of the researchers, their research, and their findings, (iv) what, if any, case studies were considered as a part of this research, (v) what, if any, scenarios regarding the development of unconventional gas resources were developed as frameworks for the research, (vi) what economic, environmental and social impacts were identified by this research, (vii) what, if any, priority research areas were identified for further study as a result of this research, (viii) what, if any, departments were involved in this research, (ix) what, if any, action was undertaken to ensure inter-departmental cooperation throughout the research process, (x) what, if any, gaps or weaknesses in the regulatory framework did the research identify; (b) what, if any, research has the government undertaken regarding balancing shale gas' potential contribution to energy security with environmental risks; (c) what are the sources of greenhouse gas emissions associated with unconventional gas; (d) has the government developed a process to determine the overall carbon footprint of shale gas throughout the life cycle of natural gas use, if not, why not, and, if so, (i) what federal departments are involved in this process, (ii) how does the government ensure inter-departmental collaboration on this process, (iii) what is the p ...

Question No. 140 Ms. Kirsty Duncan: With respect to development of the oil sands, its impacts on the environment and surrounding communities, and the economic effects of these impacts: (a) what, if any, steps has the government taken to establish air emission limits or air quality standards to achieve the World Health Organization’s Air Quality Guidelines to protect air quality and human health; (b) what, if any, steps has the government’s sector-by-sector approach taken to regulate carbon emissions in the oil sands to ensure the oil sands industry makes appropriate reductions in its greenhouse gas (GHG) emissions to contribute to Canada’s GHG emission reduction goal of 17% below the 2005 level; (c) what, if any, studies has the governmen ...[+++]t undertaken to examine the effect of the oil sands expansion on (i) GHG emissions, (ii) Canada’s ability to meet its GHG emission reduction goals, (iii) Canada’s contribution to the goal of staying below a 2°C increase in global average surface temperature, relative to the pre-industrial level, as articulated at the G8 meeting in L’Aquila, Italy and at the United Nations Framework Convention on Climate Change negotiations through the Copenhagen Accord in December 2009 and the Cancun Agreements in December 2010, (iv) the full suite of sustainability criteria, including environmental, economic and social sustainability, and (v) what were the results of any studies identified in (c)(i), (c)(ii), (c)(iii), and (c)(iv); (d) what, if any, studies has the government undertaken to examine (i) the scope of oil sands expansion if the oil sands sector is not required to deliver its proportional share of GHG reductions, (ii) the impacts such a decision would have on other sectors’ allowable GHG emissions, (iii) whether other sectors of the Canadian economy would have to do more than their proportional share to reduce emissions, (iv) what were the results of any studies identified in (d)(i), (d)(ii), and (d)(iii); (e) what, if any, studies ...
