What is a Objective Summary on Global Warming?

Global warming is the long-term heating of Earth's climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere.

Explanation:

The study, published last month in the journal Geophysical Research Letters, found that climate change is making summers hotter and longer, while shrinking the three other seasons. ... They found that over the nearly 60-year period, summers grew from an average of 78 to 95 days long

The study of how food interacts with genes is known as  nutrigenomics.  This science identifies and understands molecular-level interaction between nutrients and other dietary bioactives with the genome. The nutriegenomics studies the effects of food and food constituents on gene expression.
