a rather uniform rate. Therefore, the lake will continue to grow until it reaches the glacier
bed.
G A direct result of the melting glaciers is the change of high tides that serves the main
factor for sea level rise. The trend of sea level rise will bring a threat to the groundwater
system for its hyper-saline groundwater and then pose a possibility to decrease the
agricultural production. Many experts believe that the best way to counter this trend is to
give a longer-term view of sea level change in New Zealand. Indeed, the coastal
boundaries need to be upgraded and redefined.
H There is no doubt that global warming has affected New Zealand in many aspects. The
emphasis on the global warming should be based on the joints efforts of local people and
experts who conquer the tough period. For instance, farmers are taking a long term, multi-
generational approach to adjust the breeds and species according to the temperature.
Agriculturists also find ways to tackle the problems that may bring to the soil. In broad
terms, going forward, the systemic resilience that’s been going on a long time in the
ecosystem will continue.
I How about animals' reaction? Experts have surprisingly realised that animals have
unconventional adaptation to global warming. A study has looked at sea turtles on a few
northern beaches in New Zealand and it is very interesting to find that sea turtles can
become male of female according to the temperature. Further researches will try to find
out how rising temperatures would affect the ratio of sex reversal in their growth. Clearly,
the temperature of the nest plays a vital role in the sexes of the baby turtles.
J Tackling the problems of global warming is never easy in New Zealand, because
records show the slow process of global warming may have a different impact on various
regions. For New Zealand, the emission of carbon dioxide only accounts for 0.5% of the
world’s total, which has met the governmental standard. However, New Zealand’s effort
counts only a tip of the iceberg. So far, global warming has been a world issue that still
hangs in an ambiguous future.
