Davos Agenda: What you need to know about saving the planet

  • 2020 showed us that action on climate change is more urgent than ever.
  • Building back better must include a focus on reaching net-zero, the energy transition and committing to circular economies and sustainable consumption.
  • The Davos Agenda will mobilize global leaders to build a healthier, more resilient planet.

A year ago at the Forum's Annual Meeting in Davos – heeding the advice of speakers including Greta ThunbergUN Secretary-General Antonio Guterres and Prince Charles – government, business and civil society committed to take more concrete action on climate change and save the planet from a hotsmoky, polluted demise.

Throughout the week, delegates watched in horror as bushfires ravaged Australia – ultimately burning more than 11 million hectares of land and killing or displacing as many as 3 billion animals. By the end of the week, a Davos press conference about a new global threat – a highly infectious virus emerging in China – showed the world that we could no longer ignore the links between the health of the planet and the health of humans, economies and societies.

From 25-29 January 2021, The Davos Agenda will bring many of those leaders together again to discuss the innovative and bold solutions needed to stem the pandemic and drive a robust recovery – with a focus on the resiliency and sustainability of our ecosystems and infrastructure.

La Niña Update...

La Niña Roars, Unleashing Fire, Drought and Floods Worldwide

In the American West, the drought that paved the way for 2020’s hellscape of wildfires is poised to be even worse this year. Fanning the flames: La Niña.

The weather pattern has reached the peak of its power, wreaking havoc on a world already reeling from an unprecedented string of extreme weather brought on by climate change. Characterized by a cooling of the equatorial Pacific, La Niña triggers an atmospheric reaction that roils commodities markets across the globe—parching cropland in some areas while bringing a flood of rain to others. 

In the U.S. West, the biggest threat is drought. Even as long-awaited rain falls this week, water scarcity plagues 78% of 11 western states, according to the U.S. Drought Monitor. January should be California’s wettest month, bringing an end to fire season with frequent rain along the coast and valleys and snow in the Sierra Nevada Mountains. But with La Niña steering the winter away from the state, fire season now seems to be limitless. A record 4.2 million acres burned in the state in 2020, and the threat still hasn’t abated. At least a dozen blazes erupted this month as dry gusts rattled the southern half of the state.

Comments 1 to 5:

  1. Suggestion for upcoming digest: Seasonal origin of the thermal maxima at the Holocene and the last interglacial

    Unfortunately behind paywall, but seems to elucidate a discrepancy between data and modeling in paleoclimate.

  2. Phillippe Chantreau @1,

    Bova et al (2021) 'Seasonal origin of the thermal maxima at the Holocene and the last interglacial' certainly looks to have made some interesting and important findings but as you say it is paywalled. There is a graphic attached to this Rutgers press release which is perhaps a little clearer than the thumb-nails attached to the paywalled paper.

  3. Nature has a review of the Bova article, here.

  4. Boava et al (2021) is also the focus of:

    Climate crisis: world is at its hottest for at least 12,000 years – study by Damian Carrington, Environment, The Guardian, Jan 27, 2021

  5. Thanks for the links, the Nature review is very interesting.
