Understanding and quantifying the global methane (CH 4) budget is important for assessing
realistic pathways to mitigate climate change. Atmospheric emissions and concentrations of …

Methane (CH4) is produced in many natural systems that are vulnerable to change under a
warming climate, yet current CH4 budgets, as well as future shifts in CH4 emissions, have …

This chapter addresses the biogeochemical cycles of carbon dioxide (CO2), methane (CH4),
and nitrous oxide (N2O). The three greenhouse gases have increased in the atmosphere …

Understanding the dynamics of methane (CH 4) emissions is of paramount importance
because CH 4 has 25 times the global warming potential of carbon dioxide (CO 2) and is …

produced CH4 40 IV. Tree‐produced CH4 42 V. Trees in forest CH4 budgets 44 VI …

Plants produce a wide spectrum of biogenic volatile organic compounds (BVOCs) in various
tissues above and below ground to communicate with other plants and organisms. However …

The global budget of atmospheric CH4, which is on the order of 500–600 Tg CH4 per year,
is mainly the result of environmental microbial processes, such as archaeal methanogenesis …

Atmospheric methane is an important greenhouse gas and a sensitive indicator of climate
change and millennial-scale temperature variability. Its concentrations over the past 650,000 …

Ecosystems and the atmosphere: This review describes the state of understanding the
processes involved in the exchange of trace gases and aerosols between the earth's surface …

Climate change is occurring, is caused largely by human activities, and poses significant
risks for-and in many cases is already affecting-a broad range of human and natural …
