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
The Arctic might seem far from civilization—yet what happens at the poles affects everything.

Arctic wildfires emitted the equivalent of 244 million metric tons of carbon dioxide from January to August, compared with 181 million tons for the whole of 2019 Image
As the Arctic melts, Earth’s most dramatic warming is happening at sea.

93% of heat captured by greenhouse gases since the 1970s has been absorbed by oceans
Heat waves are becoming more intense and more frequent as the planet warms. Increased demand for air conditioning is causing sharp spikes in energy use Image
In oil-rich Saudi Arabia, power plants burn crude oil to meet additional demand in summer, so air pollution rises with heat waves Image
Those in poor countries who can’t afford air conditioning will be disproportionately affected.

By 2100, heat alone could kill as many people as heart disease does, humanity’s biggest killer Image

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 Image
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 Image

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 Image
How did the landscape change so fast?

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
