En el 2012, los latinos fueron 1 de cada 10 votantes y ayudaron a decidir las elecciones presidenciales, estableciendo un margen récord de votantes.  El mes pasado en California, el estado más populoso de Estados Unidos, la población hispana sobrepasó la de blancos no hispanos.   El único otro estado a llegar a este punto es Nuevo México, cuya población hispana-latina es casi un diez por ciento mayor que la de blancos no hispanos.

Así como la población latina continúa a crecer en todo el país, así crece su influencia en áreas de política claves.  En aquellos estados que son campos de batalla de las elecciones, como Florida, Colorado y Nevada, los latinos representaron el 17, 14 y 18 por ciento de votantes en el 2012, respectivamente, lo que refleja un aumento con relación a elecciones anteriores.  La tendencia ha reavivado una animada discusión sobre la influencia de la comunidad latina estadounidense, el “gigante dormido” en la política del país.

También hay una tendencia política menos reconocida que está surgiendo entre los grupos más jóvenes y de más rápido crecimiento: la demanda entre latinos para actuar con el fin de hacerle frente al cambio climático.  Según una nueva encuesta nacional publicada el mes pasado por Natural Resources Defense Council y Latino Decisions: Read More »

IPCC: Cutting pollution isn’t enough – we need smart adaptation, too

By / Bio / Published: April 2, 2014

Rebecca Shaw is a member of the Intergovernmental Panel on Climate Change (IPCC) and a lead author on Chapter 16, “Adaptation, Opportunities, Constraints and Limits,” of Working Group 2, Fifth Assessment Report. She is also a contributing author for the chapter, “Terrestrial Ecosystems and Inland Waters Systems,” and an author on the technical summary.

Today, the Intergovernmental Panel on Climate Change released its 2014 report on impacts, vulnerability and adaptation.

There are three top take-a-ways from the report:

  1. The documented impacts of climate change are widespread, unequivocal and consequential across the planet for both people and nature
  2. Confronting climate change is now an issue of managing risks, and those risks are greater if we continue to pollute the atmosphere.
  3. To protect ourselves from the impacts of climate change that can’t be avoided, we must make smart adaptation investments in our cities, working lands and ecosystems now. These investments will increase resilience in the face of climate change and lead to a more vibrant and secure world.

The report contains extensive documentation on the impacts the warming atmosphere is already having on agriculture, coastal communities, terrestrial and marine plants and animals, and fresh water availability. Impacts from recent extreme climatic events such as heat waves, droughts, floods and wildfires demonstrate the significant vulnerability of some ecosystems and humans systems. Poor and impoverished communities will be most vulnerable, as will species lacking the robust ability to adapt to climate change.

And the science clearly shows that rates of annual crop yield increases are slowing. Climate change acts as an anchor on production – a heavy weight that will grow heavier each year climate change proceeds unchecked and unmitigated.

As climate change impacts increase, so does the need for getting smart about cutting carbon pollution. It is equally urgent that we super charge efforts to manage the risks associated with the impacts we cannot avoid. It’s not a choice between mitigation and adaptation anymore – we need both, fast. Without action, the magnitude and rates of climate change will lead to high risk of abrupt and irreversible change in terrestrial and freshwater ecosystems. And it will pose major challenges to cities, farms and infrastructure.

Yet, there is some hope. And this is where the new report departs from the 2007 IPCC report. We found that individuals, communities, businesses and governments around the world are innovating adaptation actions, plans and policies.

Here at EDF, we’re investing in transformational adaptation projects that will ensure that people and nature will be more resilient in the face of climate change:

  • In the Mississippi River Delta we are harnessing the river’s natural processes to rebuild coastal wetlands to protect coastal communities from sea level rise and extreme weather.
  • In the drought-stricken Colorado River Basin, we’ve helped to develop water-sharing agreements that can be replicated in other water-stressed regions.
  • Across the Western U.S., we are implementing habitat-exchange programs that will dynamically protect threatened wildlife populations for the long-term, even as their ranges shift.
  • And in the Midwest, we’re working with farmers to decrease greenhouse gas pollution caused by overuse of fertilizer on crops.

These examples are demonstrating that as long as smart investments in adaptation measures are taken in concert with substantial cuts in carbon pollution, we have an opportunity to decrease our vulnerability to climate change and to build a more vibrant and secure world for all.

6 key insights from the latest IPCC climate report

By / Bio / Twitter profile / Published: April 1, 2014

(This post originally appeared on EDF Voices)

Since 1990, the United Nations’ Intergovernmental Panel on Climate Change (IPCC) has released a series of reports that assess the latest data and research on climate change.

The reports are issued approximately every five years. In September 2013, the IPCC issued its newest round of reports by sharing the latest science, concluding with more confidence than ever that humans are responsible and that weather will likely get even more extreme, along with many other key findings.

The newest report, released today, looks at impacts, adaptation and vulnerability. Next month comes the thirdreport in the 3-part series that makes up the IPCC’s 5thAssessment Report (IPCC AR5); it focuses on mitigation—that is, actions to limit the magnitude and rate of climate change.

Over 600 scientists and experts from at least 70 countries were involved in writing this latest installment of the IPCC AR5, which is referred to as Working Group II. Representatives from 195 nations had to approve of the Summary for Policymakers document line-by-line.

The report’s content focuses on three topics:

  • Impacts: effects of climate change on people, society, and ecosystems
  • Adaptation: actions to limit our risks to climate change
  • Vulnerability: the susceptibility of the human and natural worlds to climate change

Here are six key findings from the new IPCC report:

1.       Climate change is now everywhere. Impacts have been found on every continent and across all oceans. Both human and natural systems are experiencing the far-reaching and ever-growing effects: water resources are shrinking; terrestrial, freshwater, and marine species have changed their ways of life; major crop yields have decreased; and heat-related deaths have risen.

2.       Humans and ecosystems are both vulnerable. Climate events such as heat waves, droughts, floods, and wildfires alter ecosystems; disrupt food production and water supply; damage infrastructure and settlements; cause sickness and mortality; and adversely affect mental health and human livelihood. However, people who are socially, economically, culturally, politically, institutionally, or otherwise marginalized are especially vulnerable.

3.       Food security, water resources, human health, ecosystems, and the economy are all at stake. While the degree of risks varies based on climatic and non-climatic factors, scientists are confident that human and natural systems are threatened with continued warming. ‘Runaway’ warming (a global temperature increase of 4˚C (7.2˚F) above preindustrial levels—we are currently at 0.86˚C (1.5˚F)) could make normal activities like growing food or working outdoors impossible in many regions.

4.       Many global risks of climate change are concentrated in urban areas. Heat stress, extreme precipitation, inland and coastal flooding, landslides, air pollution, drought, and water scarcity pose risks in urban areas for people, assets, economies, and ecosystems.

5.       Building resilience is critical to limiting risks… Even the most rigorous mitigation tactics still won’t eliminate some additional warming. The upshot: there are countless opportunities for local, state, and national governments to plan and implement adaptation efforts, and also opportunities for public and private engagements. The down side: several barriers to adaptation still exist (such as legal and financial constraints), and if heat-trapping gas emissions remain unabated and the Earth warms by 4˚C (7.2˚F), the impacts may grow larger than our capacity to adapt.

6.       …but cutting heat-trapping gas emissions is essential. Delaying mitigation actions will likely reduce options for climate-resilient pathways, and make them much less affordable. Fortunately, we can solve two problems at once; examples of actions that build resilience and cut gas emissions include: improved energy efficiency and cleaner energy sources; reduced energy and water consumption in urban areas through greening cities and recycling water; sustainable agriculture and forestry; and protection of ecosystems for carbon storage and other ecosystem services.
