US Can Reach 85% Climate Goal By 2050: UN Report

US Can Reach 85% Climate Goal By 2050: UN Report

written by CleanTechies Staff


In America’s low-carbon future, most cars will run on electricity, carbon dioxide will be stored underground, and homes and buildings will be hyper-efficient, guzzling less energy even as the population grows. This is the vision of a new analysis that maps how the United States can drastically curb its greenhouse gas emissions by 2050. The plan,…

Disturbed Tropical Forests Store Carbon But Are Slow to Regain Plant Biodiversity, Study Says

written by Yale Environment 360

In tropical forests that are regrowing after major disturbances, the ability to store carbon recovers more quickly than plant biodiversity, researchers from the U.K. have found.

However, even after 80 years, recovering forests store less carbon than old-growth forests,

A 1.5 C Temperature Rise Could Release Greenhouse Gases in Permafrost

written by Yale Environment 360

A global temperature increase of 1.5 degrees Celsius could unleash more than 1,000 gigatons of carbon and methane currently trapped beneath Siberian permafrost and accelerate global climate change, a new study says.

In a study conducted in a frozen cave in Siberia,

BP, Peak Oil and Climate Change

written by Walter Wang

I come across several articles each day that cause me to adjust my position on where we’re going as a civilization. Here’s one on BP, peak oil, and climate change that offers an interesting nuance, concluding with the following:

As author Naomi Klein outlines in an article written in the aftermath of Hurricane Sandy last fall, it has

No Oasis for Climate in Doha Desert

written by Walter Wang

The UN climate talks failed to deliver increased cuts to carbon pollution, nor did they provide any credible pathway to $100 billion per year in finance by 2020 to help the poorest countries deal with climate change, according to the 700 NGOs who are members of Climate Action Network-International (CAN-I).

How Successful are Leading Economies Collaborating Against Climate Change?

written by Walter Wang

There is more urgency to combat climate change than before, but how are the big economies – China, the US, India – getting on together? Each country has its own agenda and is experiencing its own growing pains of one kind or another.

How does a country emit such massive quantities of carbon in the first place?

Planet’s Carbon Storing Capacity Keeping Pace with Human Emissions

written by Yale Environment 360

The earth’s oceans and lands continue to absorb more than half of the carbon dioxide emitted by human activity, suggesting that the planet has not yet reached its carbon storage capacity even as emissions continue to rise, a new study says.

Writing in the journal Nature, U.S. scientists calculate that the world’s natural systems — including seas,

Forest Carbon Loss

written by Walter Wang

The carbon cycle is a complex thing. There is carbon in the air (carbon dioxide), carbon in plants and animals, dissolved carbon in the sea and carbon in the soil that is constantly circulating to and from. Elevated levels of atmospheric carbon dioxide may accelerate carbon cycling and soil carbon loss in forests, as found in new research led by an Indiana University

When Does the Future Begin for Renewable Energy?

written by Walter Wang

The vast majority of our scientists tell us that climate change is already manifest, evidenced by the startling increase in extreme weather events, the melting of the glaciers, the measurable rises in the sea levels, etc.

The pH of the oceans is falling, potable water is becoming scarcer, food shortages are becoming

Seagrasses Hold More Carbon Per Square Kilometer Than Forests, Study Says

written by Yale Environment 360

The planet’s seagrass meadows store more than twice as much carbon per square kilometer as forests, demonstrating that coastal vegetation can play an important role in mitigating climate change, a new study says.

Writing in the journal Nature Geoscience, a team of scientists calculated that coastal seagrass beds can

Tropical Forests Store More Carbon Than Previously Believed, Study Says

written by Yale Environment 360

A new analysis calculates that vegetation in the world’s tropical regions stores about 229 billion tons of carbon, which is about 21 percent more carbon than previously believed.

Using remote sensing satellite data — including cloud-penetrating LiDAR — and field observations

Deforestation in Boreal Region Has Net Cooling Effect, Study Says

written by Yale Environment 360

While deforestation is considered a critical factor in global warming since it causes the release of carbon, scientists say that in northern latitudes tree loss may actually have a net cooling effect.

In an analysis of temperature data collected from Florida to Manitoba, researchers from 20 institutions

Chinese Sustainability: Outside Looking In

written by Walter Wang

A family trip recently brought me back to China for a few weeks. I was in a small provincial capital — quieter than Beijing or Shanghai and the kind of place that has seen explosive population growth in the past ten years.

I spent some time this trip trying to understand the
