Global Biodiversity Panel Warns Humans’ Introduction of Invasive Species Threatens Nature, Food Security

“With so many major drivers of change predicted to worsen,” said one researcher, “it is expected that the increase of invasive alien species and their negative impacts, are likely to be significantly greater.”

As wildfires burned through 3,200 acres of land on the Hawaiian island of Maui earlier this month, ultimately killing at least 115 people and destroying the city of Lahaina, some observers noted that the dry grasses that colonial occupiers introduced in the place of Hawaii’s natural forests made the fires spread faster than they would have if the land had been left intact.

On Monday, a study resulting from nearly five years of research by experts from 49 countries revealed how the grasses are among thousands of harmful invasive alien species that have been introduced by human activities and placed communities across the globe at risk, with the human-driven climate emergency often exacerbating the negative impact of invasive plant and animal species.

UN Report Shows Ozone Layer Recovery Effort ‘Sets a Precedent for Climate Action’

“Our success in phasing out ozone-eating chemicals shows us what can and must be done—as a matter of urgency—to transition away from fossil fuels, reduce greenhouse gases, and so limit temperature increase,” said one expert.

An assessment released Monday by leading science agencies highlights the effectiveness of an international treaty intended to protect the stratospheric ozone layer as well as the power of taking action now to limit global heating driven by human activity.

The Montreal Protocol on Substances That Deplete the Ozone Layer was signed in 1987 and entered into force in 1989. The landmark treaty regulates nearly 100 synthetic chemicals known as ozone-depleting substances (ODSs)—including chlorofluorocarbons (CFCs) used in air conditioners and refrigerators.

After COP27, all signs point to world blowing past the 1.5 degrees global warming limit – here’s what we can still do about it

The world could still, theoretically, meet its goal of keeping global warming under 1.5 degrees Celsius, a level many scientists consider a dangerous threshold. Realistically, that’s unlikely to happen.

Part of the problem was evident at COP27, the United Nations climate conference in Egypt.

While nations’ climate negotiators were successfully fighting to “keep 1.5 alive” as the global goal in the official agreement, reached Nov. 20, 2022, some of their countries were negotiating new fossil fuel deals, driven in part by the global energy crisis. Any expansion of fossil fuels – the primary driver of climate change – makes keeping warming under 1.5 C (2.7 Fahrenheit) compared to pre-industrial times much harder. Continue reading

175 Nations to Agree on ‘Historic’ Plastic Pollution Treaty

The treaty will be “an insurance policy for this generation and future ones, so they may live with plastic and not be doomed by it,” said one official.

The vast majority of the world’s countries agreed Wednesday to forge a legally-binding global treaty restricting plastic pollution, in a move one official said demonstrated “multilateral cooperation at its best.”

Negotiators representing 175 nations met over the past week in Nairobi, Kenya to discuss a joint proposal originally presented by Rwandan and Peruvian representatives. Continue reading
