If not us, who will act on this?

CO2 Level Rise

Ancient air bubbles trapped in ice enable us to step back in time and see what Earth's atmosphere, and climate, were like in the distant past. They tell us that levels of carbon dioxide (CO2) in the atmosphere are higher than they have been at any time in the past 400,000 years. -NASA

Global Temperature Rise

All three major global surface temperature reconstructions show that Earth has warmed since 1880. Most of the warming has occurred in the past 35 years, with 15 of the 16 warmest years on record occurring since 2001 2016 was the hottest year on record, it replaced 2015 as the hottest. 2017 is on track to top 2106. -NASA

Warming Oceans

The oceans have absorbed much of this increased heat, with the top 700 meters (about 2,300 feet) of ocean showing warming of 0.302 degrees Fahrenheit since 1969. -NASA

Glacial Retreat

Glacial retreat since 1850 has been worldwide and rapid, affecting the availability of fresh water for irrigation and domestic use, mountain recreation, animals and plants. These all depend on glacier-melt in the long term and impacts sea level rise in the oceans. Warming is impacting the countries of Iceland and Greenland dramatically and may disrupt the gulf stream, affecting the climate of Britain.

Ocean Acidification

The ongoing decrease in the pH of the Earth's oceans, caused by the uptake of carbon dioxide (CO2) from the atmosphere. is already dissolving in the more acidic seawater, and that's just one way that acidification may affect ocean life. Coral reefs are dying and dissolving the exoskeletons of marine life. -NASA

Sea Level Rise

Our oceans have been rising over the past century, and the rate has increased in recent decades. In 2014, global sea level was 2.6 inches above the 1993 average—the highest annual average in the satellite record (1993-present). Sea level continues to rise at a rate of about one-eighth of an inch per year. -National Geographic

Animal Extinction

More than two thirds of the world's wildlife could be gone by the end of the century if action isn't taken soon, a new report from the World Wildlife Fund. Since 1970, there has already been a 58% overall decline in the numbers of fish, mammals, birds and reptiles worldwide, according to the WWF's latest bi-annual Living Planet Index.

If accurate, that means wildlife across the globe is vanishing at a rate of 2% a year.
