Currently, perihelion occurs during the southern hemisphere's summer. This means that solar radiation due to both the axial tilt inclining the southern hemisphere toward the Sun, and the Earth's proximity to the Sun, will reach maximum during the southern summer and reach minimum during the southern winter.
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
Climate change can also be used more broadly to include changes to the climate that have happened throughout Earth's history. [32] Global warming—used as early as 1975 [33] —became the more popular term after NASA climate scientist James Hansen used it in his 1988 testimony in the U.S. Senate. [34] Since the 2000s, climate change has ...
Some variations in insolation are not due to solar changes but rather due to the Earth moving between its perihelion and aphelion, or changes in the latitudinal distribution of radiation. These orbital changes or Milankovitch cycles have caused radiance variations of as much as 25% (locally; global average changes are much smaller) over long ...
Climate change is driving extreme weather. By all accounts, the last few years have been brutal for the climate — and for the humans and other living things within it. Around the globe, heat ...
[2] [3] Climate change represents long-term changes in temperature and average weather patterns. [4] [5] This leads to a substantial increase in both the frequency and the intensity of extreme weather events. [6] As a region's climate changes, a change in its flora and fauna follows. [7]
As the latest report from the United Nations Intergovernmental Panel on Climate Change makes clear, while the planet has so far seen an average temperature rise of 1.2 degrees Celsius and will ...
If the emission of greenhouse gases isn't slowed, 389 out of 604 species in North America face extinction, according to the NationalAudobon Society
