问题     With many nations trying to create their own innovation economy, one of the more anticipated events almost every year is the latest global report on climate change. Each report from a United Nations panel of scientists brings a warning about specific sources of carbon pollution as well as a wake-up call on how to fix them. The newly identified eco-issues propel a renewed rush toward eco-innovation.
    The latest report from the U. N. ’s Intergovernmental Panel on Climate Change, released Thursday, looks at land use. About a quarter of the world’s ice-free land has been damaged by human activity, resulting either in the release of too much carbon or in a reduction in the absorption of carbon by plants. In addition, soil used for farming is eroding 100 times faster than it forms.
    Yet for environmental researchers, the report’s recommended solutions may be the most eagerly read. The ideas range from ways to reduce food waste to better breeding of flexible crops in dry lands. Climate necessities have become the primary source of green innovation.
    In fact, after more than two decades of similar U. N. reports, the world may now be in a technological revolution driven by a desire to tackle climate change. The fastest pace of innovation is most noticeably in creating sustainable sources of energy to replace fossil fuels.
    " Technological developments in digitalization, big data analytics, advanced computing, smart systems, additive manufacturing and robotics have opened the door to a potential new wave of innovation in the energy economy," says former U. S. Energy Secretary Ernest Moniz.
    A recent study of patents worldwide by scholars found the number of climate change technologies has risen sharply in response to higher levels of carbon pollution. "A country’s tendency to innovate and patent a climate change technology is influenced by the levels of carbon dioxide and other greenhouse gas emissions," the study found. And according to Bloomberg New Energy Finance, more than $300 billion in investment has flowed into clean energy in each of the past five years.
    As governments provide more incentives to solve climate change, " we will be surprised that it wasn’t as hard as we anticipated," says economist Paul Romer, who won a Nobel Memorial Prize in Economic Sciences. He says each country’s success in building an innovation economy depends on how well it relies on the intangible goods in discovering new ideas.
The best title for this text may be "________".
选项 A、A warning about specific sources of carbon pollution
B、Climate gloom and innovation bloom
C、Faster erosion of soil
D、Recommended solutions to climate changes
答案B
解析 主旨题。标题应该能够概括全文。本文主要讨论人类活动导致二氧化碳水平上升，从而引发能源领域(清洁能源)的创新的快速发展。B项能够恰当地概括本文的两个重要方面：气候和创新。而A项B项D项虽然在原文中有所提及，但是属于原文中局部的细节性内容，不足以概括全文，故均排除。故本题答案为B项。
