1/ Biden's goal to cut U.S. greenhouse gas emissions in half by 2030 will require sweeping changes in the power generation, transportation and manufacturing sectors.

It will also require a tremendous amount of land.

@merrill_dave reports:
2/ Right now, the U.S. energy sector uses about 81 million acres of land.

That estimate includes not only energy sources fueling the electric grid, but also transportation, home-heating and manufacturing.
3/ Two-thirds of America's total energy footprint is devoted to transportation fuels produced from agricultural crops, primarily corn grown for ethanol.

It requires more land than all other power sources combined but provides just 5% of the nation's energy.

1/ Exclusive:
Homeowners across the U.S. are being sold on a form of financing called property assessed clean energy, or PACE, which leverages the taxing authority of local governments to cover the high upfront cost of a climate-friendly renovations:
2/ Some homeowners thought they were enrolling in a free government program to make their homes more energy-efficient. Others were promised the energy savings from their renovations would quickly offset the cost.

One answered a robocall about eliminating their electricity bill.
3/ PACE isn't a mortgage, nor is it a conventional loan. Rather, homeowners pay back their balance — plus interest — via a surcharge on their annual property taxes.

1/ Exclusive:
Following concerns over the sale of millions of dollars in meaningless carbon credits to corporations like JPMorgan, BlackRock and Disney, the Nature Conservancy says it is conducting an internal review of its carbon-offset project portfolio
2/ The self-examination follows a Bloomberg Green investigation last year that found the world's largest environmental group taking credit for preserving trees in no danger of destruction:
3/ While the Nature Conservancy declined to answer specific questions about the review, it said in a statement that it aims to meet the highest standards with its carbon projects and that the inquiry will be led by scientists and a "team of experts with deep project knowledge."

We examined the political donations by some of America’s top businesses.

Here’s what we know: U.S. businesses have pledged to go green, yet their political contributions have not followed the same trend…
For every dollar these corporations gave to one of the most climate-friendly members of Congress during this election cycle, they gave nearly twice as much to obstructionists of climate focused policies
Polls show consumers are more concerned about climate and the environment than ever and they’re voting that way now too.

These corporate donations also stand in contrast to the bold claims many of these companies make

The American fracking boom and slow rise of renewables made gas look like the future of energy not too long ago.

Now, the demand for gas may be peaking decades ahead of schedule—and the future looks a lot different…
Billions have been spent on building infrastructure to support natural gas, but demand is waning decades ahead of expectation.

Renewables’ dominance may come as soon as 2028, demolishing the bridge gas was supposed to provide after coal’s demise
How did the landscape change so fast?

Global average temperature is projected to be as much as 0.75C higher in 2020 than it was in 1980 Image
While temperatures can vary from one year to another, the trend is clear. 9 of the 10 hottest years on record have happened during the 21st century Image
Even 1.5C of warming will make certain parts of the world unrecognizable. If emissions rise or stay flat, the picture gets disastrous Image

Hurricane Laura is set to make landfall on the Gulf Coast early Thursday as a powerful Category 4 storm, unleashing deadly storm surge, flash floods and destructive winds that could inflict as much as $25 billion in damage…
Already 13 storms have formed in the Atlantic—and that’s a record since scientists began tracking storms in 1851…
Handling this storm during a global pandemic is unprecedented.

A new study found that tens of thousands more people could be infected by the coronavirus depending on how emergency planning is handled…

It’s one of the scariest questions facing billions of humans on a hotter planet: How many of us will die from extreme heat in the decades ahead?

Your future risk of dying from heat will be determined by where you live and economic inequality…
A major paper released today by the @impact_lab maps the relationship between temperature, income, and mortality.

The researchers determined that the toll from heat will be far worse than expected
The global annual mortality rate at the end of this century is set to rise by average of 73 deaths per 100,000 people solely from excess heat.

That’s a death rate comparable to the 79 per 100,000 that New York State has seen from Covid-19 since January

The flow of plastics into our oceans is on a trajectory to triple over the next 20 years.

If no action is taken, the amount of plastic litter will grow to 29 million metric tons per year by 2040. Yes — you read that correctly…
Currently 11 million metric tons of plastic make their way into the oceans each year
There are some actions could be cut that volume by 80%:

♻️ creating more plastic from recyclables
♻️ improving waste collection globally
♻️ investing in plastics or materials that are easier to recycle

In April 1970, on the first Earth Day, the planet had warmed by about 0.06°C—today we're at 1.16°C
Scientists have measured the rising level of carbon dioxide in the atmosphere since the 1950s. The monthly CO2 level has risen by approximately 87 ppm since 1970—or about 27%
The ice caps are melting faster than scientists expected. We’ve been able to track this using data from the late 1970s.
As of Apr. 19, there was 13.66 million km2 of Arctic sea ice, or 5.5% lower than the historical average for the day
