Reducing fossil fuel use therefore is vital to addressing tropical forest loss, because it can help stave off even worse impacts of increasing fire, drought, and severe heat. But addressing deforestation itself can also have an outsized impact.

According to WRI, tropical forest loss is currently responsible for 8 percent of the problem, but that contribution could be key to 23 percent of the solution by The explanation here? Giving tropical forests what they need to help store more carbon requires deeper understanding of the problems they face. While great strides have been made in this field of study, it can still be difficult to precisely count tree loss. More research is also needed to capture detail on how well trees are growing back after storms, fires, or logging.

Addressing deforestation will also likely take more money, considering forest conservation is dramatically underfunded , when compared with land development financing. Continuing and expanding international cooperation is another way forward, so long as leaders look not solely at environmental and economic issues, but also at social ones. For example, indigenous rights have often been overlooked or under-considered in forest policy.

But people who have lived in and around these lands for generations could actually be meaningful allies in protecting them. By some estimates, tree cover loss is said to be less than half on indigenous or community-run land than in other areas, and the difference is even greater when their rights to the land are legally recognized. On-the-ground success stories are out there, from Brazil to Indonesia, pointing to the power of combining local efforts, socially-minded policy, and economic incentive. Repeating those successes around the world could theoretically help buy humanity another years to get off fossil fuels.

Perhaps, but clearly not a slam-dunk. But such steps might help make the case for ramping-up efforts to fight tropical deforestation. And doing so sooner rather than later.

Albedo is the fraction of solar radiation reflected from a surface, here mainly from plant bodies and, to a lesser extent, soil. There is some evidence that energy emissions from the tropics have increased to a substantial degree during the past 20 years, which appears to have some relationship to cloud cover and tropical air circulation shifts.

In some areas the air masses near the equator moved upwardly more strongly than usual, which decreased cloud cover and humidity in these areas.

Whether or not these alterations are part of the normal climatic cycles is not known Hartmann, ; Chen, Carlson and Del Genio, ; Wielicki, et al. Most of this energy is absorbed in the evaporation of water from the forest vegetation. The resultant water vapor disperses heat into the atmosphere, and so heat energy is transferred from the surface of the earth to the atmosphere. Water vapor, as clouds, can also reflect heat energy.


Tropical Deforestation and Global Warming

So it can be cooling or heating, depending upon the type and volume of cloud cover. These forest effects are not restricted to the tropics. As warm moist air moves north from tropical forested areas, heat is transferred to northern regions, and humidity and rainfall increase.

This phenomenon is known as sequestration. However, the end result of oxidation respiration is carbon dioxide, which is released as a waste product into the air, and a great deal of carbon dioxide enters the atmosphere in this way.

For comparison, United States per capita emissions are more than 5 metric tons per year, in comparison with an average of 0. Half of emitted carbon remains in the air, a quarter is absorbed by the ocean, and the remainder, approximately two petagrams, must be being taken up sequestered by terrestrial systems.

The nation has instituted a new set of deforestation reduction policies, including a national moratorium on peat drainage and publicly available transparency data which lets citizens and non-profits help the government identify areas of non-compliance. Mangroves, which are prevalent throughout the tropics, have also been identified as both an important carbon emissions sink and critical habitat in danger due to coastal development and pollution. The Blue Forests Project seeks to protect mangroves so that their ecosystem and carbon sequestration services can be best utilized.

Deforestation and climate change The tropics are key to solving the climate challenge because the tropical forests are important carbon sinks.
