RENEWABLES CAN'T DELIVER PARIS CLIMATE GOALS

Renewables can’t deliver Paris climate goals


Expansion of renewable energy cannot by itself stave off catastrophic climate change, scientists warned Monday.
Even if solar and wind capacity continues to grow at breakneck speed, it will not be fast enough to cap global warming under two degrees Celsius (3.6 degrees Fahrenheit), the target set down in the landmark 2015 Paris climate treaty, they reported in the journal Nature Climate Change.
“The rapid deployment of wind, solar and electric cars gives some hope,” lead author Glen Peters, a researcher at the Center for International Climate and Environmental Research in Oslo, Norway, told AFP.
“But at this stage, these technologies are not really displacing the growth in fossil fuels or conventional transportation.”

Earth is overheating mainly due to the burning of oil, gas and especially coal to power the global economy.
Barely 1C (1.8F) of warming so far has already led to deadly heatwaves, drought and superstorms engorged by rising seas.
The 196-nation Paris Agreement set a collective goal to cap warming, but lacks the tools to track progress, especially at the country level.
To provide a better toolkit, Peters and colleagues broke down the energy system into half-a-dozen indicators — GDP growth, energy used per unit of GDP, CO2 emissions per unit of energy, share of fossil fuels in the energy mix, etc.
Compounding the challenge, other key policies and technologies deemed essential for holding down temperatures remain woefully underdeveloped, the study cautioned.
In particular, the capacity to keep or pull carbon dioxide out of the atmosphere and store it securely — a cornerstone of end-of-century projections for a climate-safe world — is practically non-existent.
Vetted by the UN’s top climate science panel, these scenarios presume that thousands of industrial-scale carbon capture and storage (CCS) facilities will be up-and-running by 2030.
As of today, there are only one or two, with a couple of dozen in various stages of construction.

COP 23 TO UNVEIL INNOVATIVE APPROACHES TO MEASUREMENT, REPORTING AND VERIFICATION (MRV)

Image
COP 23 Side-event to showcase innovative approaches to Measurement, Reporting and Verification (MRV) Thursday 9 th  November, 2017 The event  will showcase innovative approaches endorsed by the European Union (EU) to enhance Measuring (and monitoring), Reporting and Verification (MRV) capacity and their engagement in the transparency framework under the Paris Agreement. The side event will provide an overview of three specific projects, emphasizing new solutions which can be accessed and potentially replicated in other contexts: two major EU-funded projects, the  ClimaSouth project  and the Regional implementation of Paris Agreement project (RIPAP), and Information Matters, a project supported by Germany and implemented by Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ). source: europa.eu

  System will help improve conservation and sustainable management of forests The Billion Tree Afforestation Project aims to slow down the effects of global warming in Pakistan. Image Credit: Billion Tree Tsunami Afforestation Project Islamabad: Pakistan has launched its first ever national forest monitoring system to curb illegal deforestation and degradation of land and to mitigate the effects of climate change. The forest monitoring system through satellite data would help the country improve “conservation, sustainable management of forests, enhancement of forest carbon stocks and monitor changes in the forest land use and detect deforestation land degradation activities,” said Prime Minister’s Special Assistant on Climate Change, Malik Amin Aslam. Pakistan loses forests over 27,000 hectares annually which is not only a massive environmental issue but also a major public health crisis. “There has been large-scale deforestation and land degradation in the country over last severa...

CLIMATE CHANGE: U.S. CLIMATE POLICY LEADERS RELEASE AMAZON FOREST PROTECTION PLAN

Image
A bipartisan group of former U.S. cabinet officials and chief climate negotiators has come together to build support for the Biden-Harris campaign pledge to protect the Amazon rainforests.  The group has offered concrete policy  recommendations  to Congress and Presidential Special Envoy John Kerry, to whom the task of delivering on this promise will fall. The Amazon rainforest The  Climate Principals  include three former cabinet officials and four former State Department chief climate negotiators. Collectively, the group’s members have led U.S. climate diplomacy for all Presidential  administrations  from the 1992 Rio Earth Summit to the 2015 Paris Agreement. This is the first time that such a diverse and  distinguished  bipartisan group has come together to offer concrete international climate policy recommendations for any particular geographic region or economic sector. The Principals include Bruce Babbitt, former Governor of A...
