4°C, or about
40 7°F, is the latest predicted rise in global temperature by the end of this century if current international carbon output reduction pledges are met, according to the Climate Scorecard (video above). The UK government, which would seem to approve of using actual science when discussion climate change, has released an add-on layer for GoogleEarth showing a detailed global view of what exactly those 4°C mean to the planet and those living on it.
It isn’t pretty, of course, but it’s a nightmare that’s hard to look away from—like a gruesome traffic accident. But in this case it’s a gruesome traffic accident that hasn’t happened yet, and can totally be prevented.
A quick taste:
High forest-fire danger projected to affect every populated continent. Regions moving into the high-danger category include: large areas of the United States; Mexico; South America, east of the Andes; southern and east Africa; the Sahel; eastern and southern Australia and southern Europe.
Tropical cyclones could be more intense and destructive. Global population increases, particularly in coastal areas, and sea-level rise mean greater cyclone and hurricane related losses, disruptions to infrastructure and loss of life as a result of storm surges. For major cyclone disasters flooding from storm surges has been the primary cause of death.
