Recent studies show the 20 warmest years on record have been in the past 22 years, and the top four in the past four years. Climate action must be increased fivefold to limit warming to the 1.5C scientists advise, according to the UN.
Surveyors at 97 sites found only 20,456 monarchs compared to 148,000 at the same sites last year, an 86% decline. [..] Its population has fallen by 97% since the 1980s, and is at just 99.5% of its original abundance.
Tracking 16,704 populations of 4,005 vertebrate species, the LPI finds that global populations of mammals, birds, fish, reptiles, and amphibians have declined, on average, by 60 percent between 1970 and 2014, the most recent year with available data.
A new study finds that frogs, toads, salamanders and other amphibians in the U.S. are dying off so quickly that they could disappear from half of their habitats in the next 20 years. For some of the more endangered species, they could lose half of their habitats in as little as six years.
The fecund abundance that is insects’ singular trait should enable them to recover, but only if they are given the space and the opportunity to do so.
“It’s a debate we need to have urgently,” Goulson says. “If we lose insects, life on earth will. ...” He trailed off, pausing for what felt like a long time.

Numerous studies are revealing that Earth’s remaining wilderness areas are increasingly important buffers against the effects of climate change and other human impacts. But, so far, the contribution of intact ecosystems has not been an explicit target in any international policy framework, such as the United Nations’ Strategic Plan for Biodiversity or the Paris climate agreement.
This must change if we are to prevent Earth’s intact ecosystems from disappearing completely.

The world must thrash out a new deal for nature in the next two years or humanity could be the first species to document our own extinction, warns the United Nation’s biodiversity chief.
Ahead of a key international conference to discuss the collapse of ecosystems, Cristiana Pașca Palmer said people in all countries need to put pressure on their governments to draw up ambitious global targets by 2020 to protect the insects, birds, plants and mammals that are vital for global food production, clean water and carbon sequestration.
