Tropical forests offer the greatest biodiversity of any area of Earth with over half of all plant and animal species. They are the “lungs of the world – absorbing more CO2 and producing more oxygen than any other”. A product of constant heat and abundant rain, it’s no wonder that plants grow here more vigorously than in any other biome. But it is also the biome that is under the greatest threat. Known as jungle, selva, or rainforest, these regions are in fact two distinct biomes – the evergreen and seasonal forests of the tropics.
Tropical forests are basically found in two types – the classic rainforest that has hardwood evergreen trees, and the “dry” forest or seasonal forest that sheds its leaves in the dry season.
A typical tropical forest in cross section has these layers:
Forest floor
Understory
Canopy
Emergent
The amount of biomass in these layers varies depending on the amount and patterns of rainfall, with the canopy being thickest in the rainforest. The forest floor becomes thicker as the canopy thins.
Tropical forests are found all around the equatorial regions, including:
Central America and the Caribbean
The Amazon Basin of South America
West Africa and the Congo Basin
The Indian Subcontinent
Southeast Asia and the southern coast of China
The archipelagos of The Philippines, Malaysia, and Indonesia
The north-west coasts of Australia, and most Pacific islands including Fiji and Hawai’i
The tropical forests are under greater threat than at any time, as they are cut down to make way for agriculture.
2035 Report: Plummeting Solar, Wind, and Battery Costs Can Accelerate Our Clean Energy Future
The 2035 Report is the first study of its kind to show how recent cost declines for solar, wind, and battery storage allow the U.S. to dramatically reduce generation and emissions from existing fossil power plants while retiring coal and reducing gas generation by 70 percent.
Economic & Job Growth
The rapid buildout of additional renewable energy would inject $1.7 trillion of investment into the economy and increase energy sector jobs by up to 530,000 per year through 2035, across all regions of the U.S., without raising consumer bills.
The 2035 Report’s release is accompanied by a set of policy recommendations to realize the jobs and economic benefits envisioned by the nonpartisan policy firm Energy Innovation. The primary policy recommendation is establishing a technology-neutral national clean energy standard targeting 90 percent by 2035 and 100 percent by 2045. Additional recommendations to unlock a clean energy future include complementary policies that support clean energy deployment, address wholesale market failures, remake utility grid regulation, and ensure an equitable and fair energy transition for impacted communities.
“What an incredible opportunity for economic stimulus. A federal clean energy standard, supported by government investments in deployment and American manufacturing, could put us back on track for a healthier economy. Meanwhile, continued policy leadership from the states can bolster progress.”
The 2035 time frame for near-complete decarbonization of the power sector is significant because it is 15 years earlier than projected in most state and national policy proposals, which provide little hope that the worst climate change impacts can be avoided. In October 2018, the U.N.’s Intergovernmental Panel on Climate Change warned that the world has only a dozen years to halve emissions in order to limit warming to 1.5°C.
“We’re talking about the ability to achieve near-100 percent clean electricity by 2035, in half the time most people are talking about.”
“This is exciting, because the 2035 timeframe is actually compatible with climate realities. However, this outcome isn’t possible without strong policy changes and our hope is this report can help inform the dialogue on federal, state, and corporate policies needed to achieve it.”
By 2030, the report finds the U.S. could reach over 70 percent clean electricity, reducing U.S. economy-wide emissions by 18 percent. Up to 85,000 unnecessary premature deaths associated with air pollution from power plants in the U.S. could be avoided through 2050 by reaching a 90 percent carbon-free electric generation sector by 2035, which would reduce economy-wide emissions 27 percent.
Savings & Reduced Damage from Pollution
Delivering 90 percent clean electricity by 2035 also avoids $1.2 trillion in environmental and health costs through 2050 by reducing damages from air pollution and carbon emissions.
The target year of 2035 allows sufficient time for most coal and gas plants to recover their fixed costs, thereby avoiding risk of stranded costs for consumers and investors, if the right policies are in place.
“Cost reductions in clean technology have occurred much faster than anticipated just a few years ago.”
“This is the first report to integrate the latest low prices for renewable energy and storage and shows it is technically and economically feasible to deliver 90 percent carbon-free electricity on the U.S. power grid by 2035.”
New fossil fuel generators are not needed. Wind, solar, and battery storage can provide the bulk of the 90 percent clean electricity. Existing gas plants used infrequently and combined with storage, hydropower, and nuclear power are sufficient to meet demand during periods of extraordinarily low renewable energy generation or exceptionally high electricity demand. Power generation from natural gas plants would drop by 70 percent in 2035 compared to 2019.
The study also finds that robust policy reforms are needed to reduce emissions and increase jobs will not be realized.
Cape Vultures have super stomachs. Their corrosive stomach acid enables them to devour their meals, which consist of animal carcasses often infected by toxins. They help disease from spreading to humans. They help humans live yet they are endangered, at risk of extinction.
