coral reef destruction, sand lizard revival

Climate change and coral reef destruction


Current climate targets are not enough to save the world's coral reefs - and policymakers urgently need to consider the economic benefits they bring.

Those are two of the conclusions from a UN-backed project aiming to quantify the financial costs of damaging nature.

“ There's evidence that current levels of CO2 are already causing damage to reefs ”
Alex Rogers, Institute of Zoology "Stabilising at anything more than about 350ppm will lead to further destruction, and really we need to be aiming for zero emissions."

Useful facts from the BBC news site:

OCEAN ACIDIFICATION
# Up to 50% of the CO2 released by burning fossil fuels over the past 200 years has been absorbed by the world's oceans
# This has lowered the pH value of seawater - the measure of acidity and alkalinity - by 0.1
# The vast majority of liquids lie between pH 0 (very acidic) and pH 14 (very alkaline); 7 is neutral
# Seawater is mildly alkaline with a "natural" pH of about 8.2
# The IPCC forecasts that ocean pH will fall by "between 0.14 and 0.35 units over the 21st Century, adding to the present fall of 0.1 units since pre-industrial times."

"Scientists say they now have unambiguous evidence that the warming in the Arctic is accelerating.

Computer models have long predicted that decreasing sea ice should amplify temperature changes in the northern polar region."

Arctic ice thinning at alarming rate



" The thickness of Arctic sea ice "plummeted" last winter, thinning by as much as one-fifth in some regions, satellite data has revealed.

A study by UK researchers showed that the ice thickness had been fairly constant for the previous five winters. "

Sand lizards released in Surrey, mid-Wales and Dorset



Hundreds of rare sand lizards are being released into the wild at locations in England and Wales from which they had previously disappeared.

The sand lizard was once a common sight across heathland, but the gradual destruction of its habitats has led to its extinction in many places.

400 lizards will be set free within a fortnight, the Amphibian and Reptile Conservation group said.

The reintroduction of the sand lizards is part of a 133-point action plan, intended to reverse the decline of the UK's frogs, toads, lizards and snakes.

The plan includes research, monitoring species and encouraging land-owners to create habitats such as ponds to help wildlife flourish.

Dr Tom Tew, chief scientist at Natural England, the government's conservation agency, said: "Reptiles and amphibians are coming under pressure from an increasing number of factors including habitat loss, disease and a future of climate change.

"This important reintroduction programme is an example of the action that must be taken to reverse the decline in England's biodiversity and to conserve the habitats that our unique wildlife relies upon."

  1. Let's face it Pete.....the planet is doomed. I used to think that it would take 2 centuries for man to completely rape the planet...but now....I have no doubt that it won't even take one century...maybe less. The Amazon jungle will be reduced to rumble in no time at the current rate...species are declining at a rapid rate..but that puts money in the pocket. Money that will be worthless in a barren,dead world. Well, that's my uplifting comment for the day. :)

  2. #money over #biosphere - Thanks for that Marty. The history of Europe (which I've been reading at length) shows that painful lessons need to be repeated, over and over, before the majority become more conscious. In day to day it's hard to sustain the necessary patience ...

  3. opportunities for global #biodiversity #conservation biodiversity news

    For the eighth year running, an international team of experts with experience in horizon scanning, science communication and research have produced a report that identifies arising global conservation issues.

    The team included Fauna & Flora International's Dr Abigail Entwistle and the results were published in the scientific journal Trends in Ecology & Evolution.

    Horizon scanning aims to highlight topics that are not yet widely known among conservation professionals but could have significant effects on global biodiversity.

    After reviewing 100 potential issues the team identified 15 topics most likely to have a significant impact on conservation over the next few years; these range from new developments in biotechnology, sand extraction, underwater robotics and blockchain technology.
