　A majority of the world’s climate scientists have convinced themselves, and also a lot of laymen, some of whom have political power, that the Earth’s climate is changing; that the change, from humanity’s point of view, is for the worse; and that the cause is human activity, in the form of excessive emissions of greenhouse gases such as carbon dioxide. 　A minority, though, are sceptical. Some think that recent data suggesting the Earth’s average temperature is rising are explained by natural variations in solar radiation, and that this trend may be coming to an end. Others argue that there is no conclusive evidence that modern temperatures are higher than they used to be.we believe that global warming is a serious threat, and that the world needs to take steps to try to avert it. That is the job of the politicians. But we do not believe that climate change is a certainty. There are no certainties in science. Prevailing theories must be constantly tested against evidence, and more evidence collected, and the theories tested again. That is the job of the scientists.

P是国际汽车和轻型卡车市场多种零部件的主要供应商之一。P公司正在准备标书，竞标为韩国汽车制造商K公司提供点燃系统模块；未来四年内K公司新车系列将使用这种模块。K公司在报价邀请书中说明，合同第一年供货量为200000件，后面三年为每年250000件。P公司营销专家认为，要具备竞争力，投标价格应为80元/件。其他相关数据如下所述。
(1)制造专家预计，设备投资(含安装)需1200万元。
(2)设备应可以满足4年合约生产需求，期满后需花费140万元拆除设备；设备残值90万元。
(3)直接人工和材料费用预计为40元/件。
(4)合约相关的间接现金开支变动预计为300万元/年。
(5)一开始，新产品还需要在库存和应收款方面投资，四年总计投入120万元。该投资将在四年合约期满时收回。
(6)P公司应缴纳40%的所得税。
(7)在税务方面，设1200万元设备成本在四年内平均折旧。
与此同时，P公司考虑到将要进行的并购L公司的计划，将6680万元收购新资产，并正在考虑如何融资。明年的业务规划显示，P公司有1500万元的留存收益可用于投资。在外部融资方面，公司与投资银行家的讨论显示，P公司证券的市场条件如下：票面利率10%的债券可按票面值出售。普通股可按58元/股的价格出售。
P公司当前资本结构相当理想长期债务，2.25亿；普通股，2.75亿。
财务分析显示，L公司普通股权益成本为16%。如果债务增长超过10%，则债务利率也要上浮10%。(所有计算均不考虑发行成本。)
