What is the evidence that indicates climate change?

What is the evidence that indicates climate change?

The physical and biological changes that confirm climate warming include the rate of retreat in glaciers around the world, the intensification of rainfall events, changes in the timing of the leafing out of plants and the arrival of spring migrant birds, and the shifting of the range of some species.

What contributes most to climate change?

Globally, the two biggest sectors that contribute to climate change are electricity generation (~25\%) and food & land use (~24\%). In other words, burning coal, oil, and natural gas to generate electricity is the single largest source of global emissions, but the food & land use sector is nearly tied with it.

What is the number one challenge related to climate change?

Climate change is already happening: temperatures are rising, drought and wild fires are starting to occur more frequently, rainfall patterns are shifting, glaciers and snow are melting and the global mean sea level is rising.

What is the largest source of anthropogenic greenhouse gas emissions globally?

Electricity and Heat Production (25\% of 2010 global greenhouse gas emissions): The burning of coal, natural gas, and oil for electricity and heat is the largest single source of global greenhouse gas emissions.

What are the examples of climate change in South Africa?

The various effects of climate change on rural communities are expected to include: drought, depletion of water resources and biodiversity, soil erosion, decreased subsistence economies and cessation of cultural activities. South Africa contributes considerable CO 2 emissions, being the 14th largest emitter of CO2.

Rise to the challenge of climate change

  • Adapt to our changing coastline. Protect densely populated communities along the coast from storms and flooding.
  • Bring nature into our communities.
  • Improve the natural and built systems that sustain us.
  • Create a greener energy system, with more capacity.

What is anthropogenic greenhouse effect?

The greenhouse effect is a natural phenomenon that insulates the Earth from the cold of space. Anthropogenic (human-caused) GHG emissions are modifying the Earth’s energy balance between incoming solar radiation and the heat released back into space, amplifying the greenhouse effect and resulting in climate change.
