Tropical rainforests play a critical role in regulating the global climate system—they represent the Earth's largest terrestrial CO2 sink.

For years, scientists have been puzzling over what exactly deforestation does to temperature. But a study published recently purports to have figured it out on the small scale.

Precise descriptions of forest productivity, biomass, and structure are essential for understanding ecosystem responses to climatic and anthropogenic changes. However, relations between these components are complex, in particular for tropical forests. We developed an approach to simulate carbon dynamics in the Amazon rainforest including around 410 billion individual trees within 7.8 million km.

With the growing recognition that effective action on climate change will require a combination of emissions reductions and carbon sequestration, protecting, enhancing and restoring natural carbon sinks have become political priorities. Mangrove forests are considered some of the most carbon-dense ecosystems in the world with most of the carbon stored in the soil. In order for mangrove forests to be included in climate mitigation efforts, knowledge of the spatial distribution of mangrove soil carbon stocks are critical.

Soil N is an essential element for plant growth, but its mineral forms are subject to loss to the environment by leaching and gaseous emissions. Despite its importance for the soil-plant system, factors controlling soil mineral N concentrations over large spatial scales are not well understood. We used NH4+ and NO3− concentrations (0–30 cm depth) from 469 sites across Australia, and determined soil controls on their regional variation. Soil mineral N varied regionally but depended on the different land uses. In the agricultural region of Australia, NH4+ tended to be depleted (4.9 ± 4.8 vs.

Nitrogen availability is a pivotal control on terrestrial carbon sequestration and global climate change. Historical and contemporary views assume that nitrogen enters Earth’s land-surface ecosystems from the atmosphere. Here we demonstrate that bedrock is a nitrogen source that rivals atmospheric nitrogen inputs across major sectors of the global terrestrial environment.

Donors are paying to plant a million trees as part of a drive to counter U.S. President Donald Trump’s decision to walk away from a global pact to curb climate change.

Between 2003 and 2016, the forest fires have jumped by almost 38% from 24,450 to 33,664 shows the State of Forests report 2017 released by the environment ministry.

Recently published research in the journal Environmental Research Letters found that setting a price of $20 per metric ton (about $18/short ton) of carbon dioxide could diminish deforestation b

A carbon sink is a system that absorbs carbon dioxide from the atmosphere.
